+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
 
-   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+                            Preamble
 
-   1. Definitions.
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
 
-      "License" shall mean the terms and conditions for use, reproduction,
-      and distribution as defined by Sections 1 through 9 of this document.
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
 
-      "Licensor" shall mean the copyright owner or entity authorized by
-      the copyright owner that is granting the License.
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
 
-      "Legal Entity" shall mean the union of the acting entity and all
-      other entities that control, are controlled by, or are under common
-      control with that entity. For the purposes of this definition,
-      "control" means (i) the power, direct or indirect, to cause the
-      direction or management of such entity, whether by contract or
-      otherwise, or (ii) ownership of fifty percent (50%) or more of the
-      outstanding shares, or (iii) beneficial ownership of such entity.
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
 
-      "You" (or "Your") shall mean an individual or Legal Entity
-      exercising permissions granted by this License.
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
 
-      "Source" form shall mean the preferred form for making modifications,
-      including but not limited to software source code, documentation
-      source, and configuration files.
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
 
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
 
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
 
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain
-      separable from, or merely link (or bind by name) to the interfaces of,
-      the Work and Derivative Works thereof.
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
 
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally
-      submitted to Licensor for inclusion in the Work by the copyright owner
-      or by an individual or Legal Entity authorized to submit on behalf of
-      the copyright owner. For the purposes of this definition, "submitted"
-      means any form of electronic, verbal, or written communication sent
-      to the Licensor or its representatives, including but not limited to
-      communication on electronic mailing lists, source code control systems,
-      and issue tracking systems that are managed by, or on behalf of, the
-      Licensor for the purpose of discussing and improving the Work, but
-      excluding communication that is conspicuously marked or otherwise
-      designated in writing by the copyright owner as "Not a Contribution."
+  The precise terms and conditions for copying, distribution and
+modification follow.
 
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and
-      subsequently incorporated within the Work.
+                       TERMS AND CONDITIONS
 
-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
+  0. Definitions.
 
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
+  "This License" refers to version 3 of the GNU General Public License.
 
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
 
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
 
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
 
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
 
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
 
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
 
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
 
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
+  1. Source Code.
 
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
 
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
 
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
 
-   END OF TERMS AND CONDITIONS
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
 
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS

-The Recovery Image
-==================
+**Team Win Recovery Project (TWRP)**
 
-Quick turn-around testing
--------------------------
-
-* Devices using recovery-as-boot (e.g. Pixels, which set BOARD\_USES\_RECOVERY\_AS\_BOOT)
-
-      # After setting up environment and lunch.
-      m -j bootimage
-      adb reboot bootloader
-
-      # Pixel devices don't support booting into recovery mode with `fastboot boot`.
-      fastboot flash boot
-
-      # Manually choose `Recovery mode` from bootloader menu.
-
-* Devices with a separate recovery image (e.g. Nexus)
-
-      # After setting up environment and lunch.
-      mm -j && m ramdisk-nodeps && m recoveryimage-nodeps
-      adb reboot bootloader
-
-      # To boot into the new recovery image without flashing the recovery partition:
-      fastboot boot $ANDROID_PRODUCT_OUT/recovery.img
-
-Running the tests
------------------
-
-    # After setting up environment and lunch.
-    mmma -j bootable/recovery
-
-    # Running the tests on device (under normal boot).
-    adb root
-    adb sync data
-
-    # 32-bit device
-    adb shell /data/nativetest/recovery_unit_test/recovery_unit_test
-
-    # Or 64-bit device
-    adb shell /data/nativetest64/recovery_unit_test/recovery_unit_test
-
-Running the manual tests
-------------------------
-
-`recovery-refresh` and `recovery-persist` executables exist only on systems without
-/cache partition. And we need to follow special steps to run tests for them.
-
-- Execute the test on an A/B device first. The test should fail but it will log
-  some contents to pmsg.
-
-- Reboot the device immediately and run the test again. The test should save the
-  contents of pmsg buffer into /data/misc/recovery/inject.txt. Test will pass if
-  this file has expected contents.
-
-Using `adb` under recovery
---------------------------
-
-When running recovery image from debuggable builds (i.e. `-eng` or `-userdebug` build variants, or
-`ro.debuggable=1` in `/prop.default`), `adbd` service is enabled and started by default, which
-allows `adb` communication. A device should be listed under `adb devices`, either in `recovery` or
-`sideload` state.
-
-    $ adb devices
-    List of devices attached
-    1234567890abcdef    recovery
-
-Although `/system/bin/adbd` is built from the same code base as the one in the normal boot, only a
-subset of `adb` commands are meaningful under recovery, such as `adb root`, `adb shell`, `adb push`,
-`adb pull` etc. Since Android Q, `adb shell` no longer requires manually mounting `/system` from
-recovery menu.
-
-## Troubleshooting
-
-### `adb devices` doesn't show the device.
-
-    $ adb devices
-    List of devices attached
-
- * Ensure `adbd` is built and running.
-
-By default, `adbd` is always included into recovery image, as `/system/bin/adbd`. `init` starts
-`adbd` service automatically only in debuggable builds. This behavior is controlled by the recovery
-specific `/init.rc`, whose source code is at `bootable/recovery/etc/init.rc`.
-
-The best way to confirm a running `adbd` is by checking the serial output, which shows a service
-start log as below.
-
-    [   18.961986] c1      1 init: starting service 'adbd'...
-
- * Ensure USB gadget has been enabled.
-
-If `adbd` service has been started but device not shown under `adb devices`, use `lsusb(8)` (on
-host) to check if the device is visible to the host.
-
-`bootable/recovery/etc/init.rc` disables Android USB gadget (via sysfs) as part of the `fs` action
-trigger, and will only re-enable it in debuggable builds (the `on property` rule will always run
-_after_ `on fs`).
-
-    on fs
-        write /sys/class/android_usb/android0/enable 0
-
-    # Always start adbd on userdebug and eng builds
-    on property:ro.debuggable=1
-        write /sys/class/android_usb/android0/enable 1
-        start adbd
-
-If device is using [configfs](https://www.kernel.org/doc/Documentation/usb/gadget_configfs.txt),
-check if configfs has been properly set up in init rc scripts. See the [example
-configuration](https://android.googlesource.com/device/google/wahoo/+/master/init.recovery.hardware.rc)
-for Pixel 2 devices. Note that the flag set via sysfs (i.e. the one above) is no-op when using
-configfs.
-
-### `adb devices` shows the device, but in `unauthorized` state.
-
-    $ adb devices
-    List of devices attached
-    1234567890abcdef    unauthorized
-
-recovery image doesn't honor the USB debugging toggle and the authorizations added under normal boot
-(because such authorization data stays in /data, which recovery doesn't mount), nor does it support
-authorizing a host device under recovery. We can use one of the following options instead.
-
- * **Option 1 (Recommended):** Authorize a host device with adb vendor keys.
-
-For debuggable builds, an RSA keypair can be used to authorize a host device that has the private
-key. The public key, defined via `PRODUCT_ADB_KEYS`, will be copied to `/adb_keys`. When starting
-the host-side `adbd`, make sure the filename (or the directory) of the matching private key has been
-added to `$ADB_VENDOR_KEYS`.
-
-    $ export ADB_VENDOR_KEYS=/path/to/adb/private/key
-    $ adb kill-server
-    $ adb devices
-
-`-user` builds filter out `PRODUCT_ADB_KEYS`, so no `/adb_keys` will be included there.
-
-Note that this mechanism applies to both of normal boot and recovery modes.
-
- * **Option 2:** Allow `adbd` to connect without authentication.
-   * `adbd` is compiled with `ALLOW_ADBD_NO_AUTH` (only on debuggable builds).
-   * `ro.adb.secure` has a value of `0`.
-
-Both of the two conditions need to be satisfied. Although `ro.adb.secure` is a runtime property, its
-value is set at build time (written into `/prop.default`). It defaults to `1` on `-user` builds, and
-`0` for other build variants. The value is overridable via `PRODUCT_DEFAULT_PROPERTY_OVERRIDES`.
+You can find a compiling guide [here](http://forum.xda-developers.com/showthread.php?t=1943625 "Guide").

+ * LISTXATTR(2)             Linux Programmer's Manual            LISTXATTR(2)
+ *
+ *
+ *
+ * NAME
+ *        listxattr, llistxattr, flistxattr - list extended attribute names
+ *
+ * SYNOPSIS
+ *        #include <sys/types.h>
+ *        #include <attr/xattr.h>
+ *
+ *        ssize_t listxattr (const char *path,
+ *                             char *list, size_t size);
+ *        ssize_t llistxattr (const char *path,
+ *                             char *list, size_t size);
+ *        ssize_t flistxattr (int filedes,
+ *                             char *list, size_t size);
+ *
+ * DESCRIPTION
+ *        Extended  attributes  are  name:value  pairs associated with inodes
+ *        (files, directories, symlinks, etc).  They are  extensions  to  the
+ *        normal  attributes which are associated with all inodes in the sys-
+ *        tem (i.e. the stat(2)  data).   A  complete  overview  of  extended
+ *        attributes concepts can be found in attr(5).
+ *
+ *        listxattr retrieves the list of extended attribute names associated
+ *        with the given path in the filesystem.  The  list  is  the  set  of
+ *        (NULL-terminated)  names,  one  after the other.  Names of extended
+ *        attributes to which the calling process does not have access may be
+ *        omitted  from  the  list.  The length of the attribute name list is
+ *        returned.
+ *
+ *        llistxattr is identical to listxattr, except in the case of a  sym-
+ *        bolic  link, where the list of names of extended attributes associ-
+ *        ated with the link itself is retrieved, not the file that it refers
+ *        to.
+ *
+ *        flistxattr is identical to listxattr, only the open file pointed to
+ *        by filedes (as returned by open(2)) is  interrogated  in  place  of
+ *        path.
+ *
+ *        A  single  extended  attribute  name  is  a  simple NULL-terminated
+ *        string.  The name includes a namespace prefix; there  may  be  sev-
+ *        eral, disjoint namespaces associated with an individual inode.
+ *
+ *        An  empty  buffer  of  size  zero can be passed into these calls to
+ *        return the current size of the list of  extended  attribute  names,
+ *        which  can be used to estimate the size of a buffer which is suffi-
+ *        ciently large to hold the list of names.
+ *
+ * EXAMPLES
+ *        The list of names is returned as an unordered array of  NULL-termi-
+ *        nated  character  strings  (attribute  names  are separated by NULL
+ *        characters), like this:
+ *               user.name1\0system.name1\0user.name2\0
+ *
+ *        Filesystems like ext2, ext3 and  XFS  which  implement  POSIX  ACLs
+ *        using extended attributes, might return a list like this:
+ *               system.posix_acl_access\0system.posix_acl_default\0
+ *
+ * RETURN VALUE
+ *        On  success,  a  positive number is returned indicating the size of
+ *        the extended attribute name list.  On failure, -1 is  returned  and
+ *        errno is set appropriately.
+ *
+ *        If  the  size  of  the list buffer is too small to hold the result,
+ *        errno is set to ERANGE.
+ *
+ *        If extended attributes are not supported by the filesystem, or  are
+ *        disabled, errno is set to ENOTSUP.
+ *
+ *        The errors documented for the stat(2) system call are also applica-
+ *        ble here.

+		 * regardless of logging level. This will give you some strings that you can grep for and find the actual crypto provider in use. In our case there were

+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>

+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see

+
+    fsck: Verify first cluster of a file is not 1
+    
+    Previously the FAT was checked for any out of bounds entries which were
+    cleared. However the first cluster of a file, as specified in its
+    directory entry, was not verified to not be 1.
+    
+    In addition to missing this filesystem error, code that correctly
+    assumes the FAT contained no bad entries anymore could still look up
+    invalid table indices depending on the value stored in entry 1. With
+    the right values and FAT size this can lead to a segfault by accessing
+    unallocated memory.
+    
+    Now test_file() will ignore files where the first cluster equals 1 and
+    an additional check in check_file() will truncate them.
+    
+    This bug was reported in http://bugs.debian.org/773885 by Jakub Wilk.

+
+    Fix attempt to rename root dir in fsck due to uninitialized fields
+    
+    When add_file() is called with offset 0, it will construct a DIR_ENT for
+    the root directory instead of reading the contents from the filesystem.
+    It did not initialize the whole DIR_ENT on the stack, just select
+    values.
+    
+    In particular, the lcase field was left with an undefined value. If
+    that value happened to include the FAT_NO_83NAME bit, the "neither long
+    nor short file name" check in bad_name() added in 3.0.26 would trigger
+    and cause an attempt to rename the entry (which is not possible).
+    Example run:
+    
+        $ /sbin/fsck.fat -y bad.img
+        fsck.fat 3.0.26 (2014-03-07)
+        /
+          Bad short file name ().
+          Auto-renaming it.
+          Renamed to
+        bad.img: 14 files, 19388/403266 clusters
+    
+    This commit changes the initialization zeroize the whole struct before
+    setting individual fields. Thanks to AlexisM, who found the cause and
+    posted a patch on the Debian bug http://bugs.debian.org/764992 .

+Date:   Tue Nov 11 22:49:50 2014 +0100
+
+    Support long file names in volume labeling code
+    
+    The code to find the volume label directory entry in find_volume_de()
+    did not consider long file names so far. Directory entries that make up
+    long file names have four attribute bits set, including the "volume"
+    bit.
+    
+    This caused the code to mistake a directory entry that is part of a
+    long file name as the volume name entry. If such an entry is found
+    first, fatlabel would print garbage when asked to display the label and
+    mangle the long file name when asked to set it. The latter would lead
+    to the loss of the long file name and require a fsck to clean up.
+    
+    Change so that the set of attributes equal that of LFN entries will no
+    langer match as a volume label.

+
+    Fix "odd" files created by frequent power-loss.
+    
+    After running many power losses the filesystem can degrate, containing "odd"
+    files making the filesystem corrupt that could not be solved by fsck:
+    
+      * file was not visible in a ls -l
+      * ls -i reported a "invalid file name" on the console
+      * a test program with diropen/dirread showed the file, a stat on this file
+        failed
+      * file was not accessible and could not be deleted
+    
+    After digging into the code we found why fsck didn't repair the file system:
+    One thing was we don't have short filenames. Another issue was that the LFN
+    pointer was set to NULL and so it looked like we didn't have short and long
+    filenames.
+    
+    Our patch of check.c includes:
+    
+      * returns 1 from function bad_name() in case no short and no long filename
+        exist
+      * auto_rename() and rename_file() got a special handling for the case no short
+        file name exist:
+        - it enables the short file name (we think here was a weakness of the old
+          code: it changed the short filename but didn't enabled it in the
+          file->dir_ent.lcase entry)
+        - it reset all attributes except ATTR_DIR and ATTR_VOLUME
+    
+    This solved our problem pretty well.

+    It seems there is problem in the double conversion on big endians.
+    The first conversion is done by the explicit conversion to __u16
+    in the GET_UNALIGNED_W macro, so the secondary conversion by le16toh
+    seems to be redundant (and wrong).

+Date:   Tue Oct 15 01:29:33 2013 +0400
+
+    Fixing "Fixing default sectors per cluster for FAT32" for UEFI.
+    
+    FAT32 "EFI System Partition" is basically required for UEFI boot;
+    commit ge048a8d broke that for me with both virtualbox-4.2 and
+    real hardware (ASUS C60M1-I to be exact) given ~250Mb filesystem.
+    
+    This commit amends that one by reverting its effects for these
+    small sizes by restoring 512b cluster size for <= 260Mb FAT32.

+
+    Don't align FAT32 reserved sectors to cluster size.
+    
+    For certain file system sizes (in particular, exact GB sizes -
+    don't ask me why) a Technisat HD S2 Plus DVB receiver will still
+    choke on mkdosfs generated file systems, even if the sectors per

+    
+    By comparing the properties of generated FAT32 FS with results
+    of the Windows tool "h2format" (www.heise.de/download/h2format.html),
+    I found that the remaining problems were caused by rounding of the
+    reserved sectors and FAT space to cluster size (the h2format tool
+    doesn't do this).

+
+    Allow operation on SH4 CPUs and remove compiler warnings.
+    
+    Simplify the GET_UNALIGNED_W macro and use it in all cases instead of making it
+    conditional on CPU types. This missed some CPUs that needed it (e.g. SH4), and
+    in any case the implementation caused "dereferencing type-punned pointer will
+    break strict-aliasing rules" warnings.
+    
+    Enable extra warnings, but disable signed comparison and missing field
+    initializer warnings as these are not helpful.
+    
+    Update write_boot_label() so that the boot_sector_16 and boot_sector cases are
+    handled separately instead of using an aliased pointer, as that causes
+    "dereferencing type-punned pointer will break strict-aliasing rules" warnings.
+    
+    Make date_dos2unix(), usage() and cdiv() static functions as they are only used
+    in the files in which they are declared.
+    
+    Update bad_name() and lfn_get() so that the extension is processed separately
+    instead of by indexing past the end of the name field as that causes "array
+    subscript is above array bounds" warnings.
+    
+    Update the dosfsck() main function to avoid a warning that free_clusters may
+    be used uninitialized. Do not print the final count of files and clusters when
+    dosfsck is run with the "-b" option because the used files and clusters have
+    not been counted in this case.

+
+    Correcting miscalculation of sector number in some cases.
+    
+    mkdosfs will incorrectly calculate the number of sectors of a
+    given FAT partition if the number sectors are odd due to
+    count_blocks incorrectly handling the remainder of a division
+    operation. This miscalculation causes the OMAP4 bootloader to
+    fail to boot.
+    
+    This bug can be observed by comparing the total sector size in
+    fdisk expert more to fsck.msdos; this discrepancy only shows up
+    when the number of sectors are odd.
+    
+    See https://bugs.launchpad.net/ubuntu/+source/dosfstools/+bug/794043

+
+    When compiling a 32-bit version of dosfstools on an x86_64 machine,
+    the resulting applications report strange errors on "large" (> 2 GiB)
+    partitions:
+    
+      Seek to -2118967808:Invalid argument
+    
+      Warning: Filesystem is FAT32 according to fat_length and fat32_length fields,
+      but has only 8613 clusters, less than the required minimum of 65525.
+      This may lead to problems on some systems.
+    
+    This appears to be due to compilation with a 32-bit off_t and lseek() library
+    function.
+    
+    Use lseek64 for positioning, and change some suspect uses of off_t to loff_t.

+    mkdosfs: correct alignment of the root directory.
+    
+    Correct the code to align the root directory; it was broken before
+    since bs.dir_entries had already been set at the point of alignment.
+    This patch removes the dual use of bs.dir_entries and root_dir_entries
+    to carry the same information: the information is carried in
+    root_dir_entires exclusively, and then bs.dir_entries is set inside
+    setup_tables() at a late point.
+    
+    The code to align the root directory is also wrapped in
+    if (align_structures); this avoids rounding the number of root
+    directory entries up to a whole sector when used with -a
+    (i.e. preserves the previous behavior.)

+        (Before, this was not tested for. Up to 65535 clusters were accepted
+        as good).
+    
+      * For FAT32 filesystems with less than 65525 a warning message will be

+    Macro MSDOS_FAT12 is now replaced by FAT12_THRESHOLD to make it

+Announcing the release of mkdosfs version 0.3b (Yggdrasil)
+
+It seems I didn't get the bug completely fixed in 0.3a.  Some
+borderline cases would still allocate too many sectors for the FAT.
+Again, nothing to worry about, just a nitpick -- this one would only
+in certain cases add one sector per FAT.
+
+Announcing the release of mkdosfs version 0.3a (Yggdrasil)
+
+Fixed a bug which would cause too many sectors to be reserved for the
+FAT (filesystem will still work fine, but have slightly less space
+available).
+
+Announcing the release of mkdosfs version 0.3 (Yggdrasil)
+
+This version correctly handles even very large filesystems, and
+properly supports the modern (3.3+) DOS bootsector format, including a
+message printed on boot attempts.

+			    --------------
+
+Announcing the release of mkdosfs version 0.2
+
+
+I've just uploaded mkdosfs to sunsite.unc.edu.  It works in a similar way
+to Remy Card's mke2fs, but creates an MS-DOS filesystem.
+
+The filename is mkdosfs-0.2.tar.gz.
+
+This second release should fix a small bug that could lead to FAT sizes that
+Linux's dosfs would accept but MS-DOS wouldn't.
+
+The archive contains a manual page, binary and source versions.

+version 2.11
+============
+
+ - all: don't use own llseek() anymore, glibc lseek() does everything we need
+ - dosfsck: lfn.c: avoid segfault
+ - dosfsck: check.c, lfn.c: check for orphaned LFN slots
+ - dosfsck: check.c alloc_rootdir_entry(): set owner of newly alloced clusters
+ - dosfsck: dosfsck.h: better use <byteswap.h> for byte swapping
+ - dosfsck: io.c: added code for real DOS
+ - mkdosfs: raised FAT12_THRESHOLD from 4078 to 4085, introduced MIN_CLUST_32
+ - mkdosfs: fix loop device size
+ - mkdosfs: by default, use FAT32 on devices >= 512MB
+ - mkdosfs: fix a memory leak (blank_sector)
+ - mkdosfs: fix parsing of number of blocks on command line, so that numbers
+   >2G can be used
+ - mkdosfs: add 'b' to getopt() string so this option can be used :)
+ - mkdosfs: fix parsing of -i arg (should be unsigned)
+ - mkdosfs: change default permissions of created images (-C) to 0666 & ~umask
+ - mkdosfs: relax geometry check: if HDIO_GETGEO fails, print a warning and
+   default to H=255,S=63
+ - dosfsck: new option -n (no-op): just check non-interactively, but
+   don't write anything to filesystem
+ - A few #include changes to support compilation with linux 2.6
+   headers (thanks to Jim Gifford <jim@jg555.com>)
+ - dosfsck: remove directory entries pointing to start cluster 0, if they're
+   not "." or ".." entries that should actually point to the root dir
+   (pointed out by Thomas Winkler <twinkler@sysgo.de>)
+ - mkdosfs: new option -h to set number of hidden sectors
+   (thanks to Godwin Stewart <gstewart@spamcop.net>)
+ - all: updated my mail address everywhere...
+
+version 2.10
+============
+
+ - dosfsck: various 64-bit fixes and removed some warnings by Michal
+   Cihar <mcihar@suse.cz>
+ - mkdosfs: better error message if called without parameters (also
+   suggested by Michal)
+
+version 2.9
+===========
+
+ - dosfsck: if EOF from stdin, exit with error code
+ - dosfsck: Fix potential for "Internal error: next_cluster on bad cluster".
+ - dosfsck: When clearing long file names, don't overwrite the dir
+   entries with all zeros, but put 0xe5 into the first byte.
+   Otherwise, some OSes stop reading the directory at that point...
+ - dosfsck: in statistics printed by -v, fix 32bit overflow in number
+   of data bytes.
+ - dosfsck: fix an potential overflow in "too many clusters" check
+ - dosfsck: fix 64bit problem in fat.c (Debian bug #152769)
+ - dosfsck: allow FAT size > 32MB.
+ - dosfsck: allow for only one FAT
+ - dosfsck: with -v, also check that last sector of the filesystem can
+   be read (in case a partition is smaller than the fs thinks)
+ - mkdosfs: add note in manpage that creating bootable filesystems is
+   not supported.
+ - mkdosfs: better error message with pointer to -I if target is a
+   full-disk device.
+
+version 2.8
+===========
+
+ - dosfsck: Fixed endless loop whenever a volume label was present.
+
+version 2.7
+===========
+
+ - dosfsck: Don't check volume label for bad characters, everything
+   seems to be allowed there... Also ignore duplicate names where one of
+   them is a volume label.
+
+version 2.6
+===========
+
+ - mkdosfs: Added correct heads definition for 2.88M floppies if not
+   created via loopback.
+ - dosfsck: If boot sector and its backup are different (FAT32), offer
+   to write the backup to sector 0. (tnx to Pavel Roskin for this)
+ - For 64 bit alpha, struct bootsector in dosfsck.h must be defined
+   with __attribute__((packed)).
+ - mkdosfs now actually accepts -R option. (tnx to David Kerrawn)
+ - Fixed typo in dosfsck boot.c (recognition of boot signature in FSINFO)
+ - Various compilation fixes for 2.4 kernel headers and for ia64.
+
+version 2.5
+===========
+
+ - The llseek() implementation for alpha didn't really work; fixed it.
+
+version 2.4
+===========
+
+ - Fix compiling problem on alpha (made a silly typo...)
+
+version 2.3
+===========
+
+ - mkdosfs: Fixed usage message (printed only "bad address").
+ - both: made man pages and usage statements more consistent.
+ - both: fix llseek function for alpha.
+ - dosfsck: fix reading of unaligned fields in boot sector for alpha.
+ - dosfsck: fixed renaming of files (extension wasn't really written).
+
+version 2.2
+===========
+
+ - Added dosfsck/COPYING, putting dosfsck officially under GPL (Werner
+   and I agree that it should be GPL).
+ - mkdosfs: Allow creation of a 16 bit FAT on filesystems that are too
+   small for it if the user explicitly selected FAT16 (but a warning
+   is printed). Formerly, you got the misleading error message "make
+   the fs a bit smaller".
+ - dosfsck: new option -y as synonym for -y; for compability with
+   other fs checkers, which also accept this option.
+ - dosfsck: Now prints messages similar to e2fsck: at start version
+   and feature list; at end number of files (and directories) and
+   number of used/total clusters. This makes the printouts of *fsck at
+   boot time nicer.
+ - dosfsck: -a (auto repair) now turns on -f (salvage files), too. -a
+   should act as non-destructive as possible, so lost clusters should
+   be assigned to files. Otherwise the data in them might be
+   overwritten later.
+ - dosfsck: Don't drop a directory with lots of bad entries in
+   auto-repair mode for the same reason as above.
+ - dosfsck: avoid deleting the whole FAT32 root dir if something is
+   wrong with it (bad start cluster or the like).
+ - general: also create symlinks {mkfs,fsck}.vfat.8 to the respective
+   real man pages.
+
+version 2.1
+===========
+
+ - Fix some forgotten loff_t's for filesystems > 4GB. (Thanks to
+   <ki@kretz.co.at>).
+ - Fix typo in mkdosfs manpage.
+ - Removed inclusion of <linux/loop.h> from mkdosfs.c; it's unnecessary and
+   caused problems in some environments.
+ - Fix condition when to expect . and .. entries in a directory. (Was
+   wrong for non-FAT32 if first entry in root dir was a directory also.)
+ - Also create mkfs.vfat and fsck.vfat symlinks, so that also
+   filesystems listed with type "vfat" in /etc/fstab can be
+   automatically checked.
+
+version 2.0
+===========
+
+ - merge of mkdosfs and dosfstools in one package
+ - new maintainer: Roman Hodek <Roman.Hodek@informatik.uni-erlangen.de>
+ - FAT32 support in both mkdosfs and dosfsck
+ - VFAT (long filename) support in dosfsck
+ - Support for Atari variant of MS-DOS filesystem in both tools
+ - Working support for big-endian systems in both tools
+ - Better support for loop devices in mkdosfs: usual floppy sizes are
+   detected and media byte etc. set accordingly; if loop fs has no
+   standard floppy size, use hd params
+   (mainly by Giuliano Procida <gpp10@cus.cam.ac.uk>)
+ - Removed lots of gcc warnings
+ - Fixed some minor calculation bugs in mkdosfs.
+
+For change logs previous to 2.0, see the CHANGES files in the subdirectories.

+dosfsck, version 1
+==================
+
+WARNING: This is ALPHA test software. Use at your own risk.
+
+dosfsck is the Linux equivalent of PC/MS-DOS' CHKDSK. It checks the
+consistency of PC/MS-DOS filesystems and optionally tries to repair
+them. The tests dosfsck performs are described in the man page.
+
+dosfsck needs header files from dosfs.9 (or later) to compile.
+
+Before using dosfsck to repair a filesystem that contains data of any
+value, you should verify that dosfsck is able to correct all reported
+errors. (Except fatal errors and those reported as unfixable, of
+course.) In order to do this, run it with the -V option, e.g.
+
+   dosfsck -V /dev/sda1		(automatic check)
+or dosfsck -V -r /dev/sda1	(interactive check and repair)
+
+dosfsck will perform two passes: in the first pass, inconsistencies are
+detected and a list of changes to correct the problems is generated. In
+the second pass, those changes are applied whenever dosfsck reads data
+from disk. Hence no fixable errors should be reported in the second
+pass if the first pass was successful.
+
+Please notify the author if fixable errors are reported in the second
+pass.
+
+After verifying that dosfsck appears to be able to perform the desired
+operations, either confirm that you want the changes to be performed
+(if dosfsck was started with -r) or re-run dosfsck with the -a option
+(if it was started without -r).
+
+Please send bug reports, comments, flames, etc. to
+almesber@nessie.cs.id.ethz.ch  or  almesber@bernina.ethz.ch

+
+FAT32 and LFN support
+=====================
+
+I've finally implemented some of the new features of MS-DOS
+filesystems: FAT32 and long filenames.
+
+FAT32 is automatically detected and of course the different FAT
+structure is handled. (Internally many changes were needed, so 32 bit
+variables for all cluster numbers and 64 bit vars for offsets inside
+the filesystem.) New checks for FAT32 are most notably on the backup
+boot sector and the new info sector. Also the possibility that the
+root directory resides in a cluster chain (instead of in a static
+area) on FAT32 is handled.
+
+dosfscheck also knows about VFAT long filenames now. It parses those
+names and uses them in listings etc. when available. There are also
+some checks on the (cruel) structure of how LFNs are stored and some
+attempts to fix problems.
+

+Atari format support
+====================
+
+Both mkdosfs and dosfsck now can also handle the Atari variation of
+the MS-DOS filesystem format. The Atari format has some minor
+differences, some caused by the different machine architecture (m68k),
+some being "historic" (Atari didn't change some things that M$
+changed).
+
+Both tools automatically select Atari format if they run on an Atari.
+Additionally the -A switch toggles between Atari and MS-DOS format.
+I.e., on an Atari it selects plain DOS format, on any other machine it
+switches to Atari format.
+
+The differences are in detail:
+
+ - Atari TOS doesn't like cluster sizes != 2, so the usual solution
+   for bigger partitions was to increase the logical sector size. So
+   mkdosfs can handle sector sizes != 512 now, you can also manually
+   select it with the -S option. On filesystems larger than approx. 32
+   MB, the sector size is automatically increased (stead of the
+   cluster size) to make the filesystem fit. mkdosfs will always use 2
+   sectors per cluster (also with the floppy standard configurations),
+   except when directed otherwise on the command line.
+
+ - From the docs, all values between 0xfff8 and 0xffff in the FAT mark
+   an end-of-file. However, DOS usually uses 0xfff8 and Atari 0xffff.
+   This seems to be only an consmetic difference. At least TOS doesn't
+   complain about 0xffff EOF marks. Don't know what DOS thinks of
+   0xfff8 :-) Anyway, both tools use the EOF mark common to the
+   system (DOS/Atari).
+
+ - Something similar of the bad cluster marks: On Atari the FAT values
+   0xfff0 to 0xfff7 are used for this, under DOS only 0xfff7 (the
+   others can be normal cluster numbers, allowing 7 more clusters :-)
+   However, both systems usually mark with 0xfff7. Just dosfsck has to
+   interpret 0xfff0...0xfff7 differently.
+
+ - Some fields in the boot sector are interpreted differently. For
+   example, Atari has a disk serial number (used to aid disk change
+   detection) where DOS stores the system name; the 'hidden' field is
+   32 bit for DOS, but 16 bit for Atari, and there's no 'total_sect'
+   field; the 12/16 bit FAT decision is different: it's not based on
+   the number of clusters, but always FAT12 on floppies and FAT16 on
+   hard disks. mkdosfs nows about these differences and constructs the
+   boot sector accordingly.
+
+ - In dosfsck, the boot sector differences also have to known, to not
+   warn about things that are no error on Atari. In addition, most
+   Atari formatting tools fill the 'tracks' and 'heads' fields with 0
+   for hard disks, because they're meaningless on SCSI disks (Atari
+   has/had no IDE). Due to this, the check that they should be
+   non-zero is switched off.
+
+ - Under Atari TOS, some other characters are illegal in filenames:
+   '<', '>', '|', '"', and ':' are allowed, but all non-ASCII chars
+   (codes >= 128) are forbidden.

+mkdosfs - Make DOS filesystem utilty.
+
+
+I wrote this, partially to complement the dosfsck utility written by Werner
+Almesberger (who graciously gave me some pointers when I asked for some
+advice about writing this code), and also to avoid me having to boot DOS
+just to create data partitions (I use Linux to back up DOS :-) ).
+
+The code is really derived from Remy Card's mke2fs utility - I used this as a
+framework, although all of the filesystem specific stuff was removed and the
+DOS stuff inserted.  I believe originally mke2fs was based on Linus' mkfs
+code, hence the acknowledgements in the source code.
+
+Neither Remy nor Linus have had any involvement with mkdosfs, so if there are
+any bugs they're almost certainly "all my own work".
+
+The code has been available for ftp since 1st September 1993, and I have yet
+to receive any bug reports from users.  I don't know of any bugs, but if you
+do find a bug or have any constructive comments, please mail me!
+
+The only bug I found with version 0.1 was an obscure fault that could lead
+to an invalid (for MS-DOS, not Linux's dos fs) number of sectors used in the
+file allocation table(s).
+
+

+
+
+FAT32 support
+=============
+
+mkdosfs now can also create filesystems in the new FAT32 format. To do
+this, give mkdosfs a "-F 32" option. FAT32 isn't selected
+automatically (yet), even if very large clusters are needed with
+FAT16. With FAT32 you have two additional options, -R to select the
+number of reserved sectors (usually 32), and -b to select the location
+of the backup boot sector (default 6). Of course such a backup is
+created, as well as the new info sector. On FAT32, the root directory
+is always created as a cluster chain. Sorry, there's no switch to
+generate an old static root dir.
+
+One bigger bug fix besides FAT32 was to reject filesystems that need a
+16 bit FAT to fit all possible clusters, but the bigger FAT needs some
+more sectors, so the total number of clusters drop below the border
+where MS-DOS expects a 12 bit FAT. So such filesystems would be FAT16,
+but interpreted as FAT32 by DOS. The fix is to reduce filesystem size
+a bit.

+\fBfsck.fat\fP [\fIOPTIONS\fP] \fIDEVICE\fP
+.SH DESCRIPTION
+\fBfsck.fat\fP verifies the consistency of MS\-DOS filesystems and optionally
+tries to repair them.
+.PP
+The following filesystem problems can be corrected (in this order):
+.IP * 4
+FAT contains invalid cluster numbers.  Cluster is changed to EOF.
+.IP * 4
+File's cluster chain contains a loop.  The loop is broken.
+.IP * 4
+Bad clusters (read errors).  The clusters are marked bad and they are
+removed from files owning them.  This check is optional.
+.IP * 4
+Directories with a large number of bad entries (probably corrupt).  The
+directory can be deleted.
+.IP * 4
+Files . and .. are non\-directories.  They can be deleted or renamed.
+.IP * 4
+Directories . and .. in root directory.  They are deleted.
+.IP * 4
+Bad filenames.  They can be renamed.
+.IP * 4
+Duplicate directory entries.  They can be deleted or renamed.
+.IP * 4
+Directories with non\-zero size field.  Size is set to zero.
+.IP * 4
+Directory . does not point to parent directory.  The start pointer is
+adjusted.
+.IP * 4
+Directory .. does not point to parent of parent directory.  The start
+pointer is adjusted.
+.IP * 4
+Start cluster number of a file is invalid.  The file is truncated.
+.IP * 4
+File contains bad or free clusters.  The file is truncated.
+.IP * 4
+File's cluster chain is longer than indicated by the size fields.  The file
+is truncated.
+.IP * 4
+Two or more files share the same cluster(s).  All but one of the files are
+truncated.  If the file being truncated is a directory file that has already
+been read, the filesystem check is restarted after truncation.
+.IP * 4
+File's cluster chain is shorter than indicated by the size fields.  The file
+is truncated.
+.IP * 4
+Clusters are marked as used but are not owned by a file.  They are marked as
+free.
+.PP
+Additionally, the following problems are detected, but not repaired:
+.IP * 4
+Invalid parameters in boot sector
+.IP * 4
+Absence of . and .. entries in non\-root directories
+.PP
+.\" ----------------------------------------------------------------------------
+When \fBfsck.fat\fP checks a filesystem, it accumulates all changes in memory
+and performs them only after all checks are complete.  This can be disabled
+with the \fB\-w\fP option.
+.SH OPTIONS
+.IP \fB\-a\fP 4
+Automatically repair the filesystem.  No user intervention is necessary.
+Whenever there is more than one method to solve a problem, the least
+destructive approach is used.
+.IP \fB\-A\fP 4
+Use Atari variation of the MS\-DOS filesystem.  This is default if
+\fBfsck.fat\fP is run on an Atari, then this option turns off Atari format.
+There are some minor differences in Atari format: Some boot sector fields
+are interpreted slightly different, and the special FAT entries for
+end\-of\-file and bad cluster can be different.  Under MS\-DOS 0xfff8 is used
+for EOF and Atari employs 0xffff by default, but both systems recognize all
+values from 0xfff8...0xffff as end\-of\-file.  MS\-DOS uses only 0xfff7 for bad
+clusters, where on Atari values 0xfff0...0xfff7 are for this purpose (but
+the standard value is still 0xfff7).
+.IP \fB\-b\fP 4
+Make read\-only boot sector check.
+.IP "\fB\-d\fP \fIPATH\fP" 4
+Delete the specified file.  If more than one file with that name exist, the
+first one is deleted.  This option can be given more than once.
+.IP \fB\-f\fP 4
+Salvage unused cluster chains to files.  By default, unused clusters are
+added to the free disk space except in auto mode (\fB\-a\fP).
+.IP \fB\-l\fP 4
+List path names of files being processed.
+.IP \fB\-n\fP 4
+No\-operation mode: non\-interactively check for errors, but don't write
+anything to the filesystem.
+.IP \fB\-p\fP 4
+Same as \fB\-a\fP, for compatibility with other *fsck.
+.IP \fB\-r\fP 4
+Interactively repair the filesystem.  The user is asked for advice whenever
+there is more than one approach to fix an inconsistency.  This is the
+default mode and the option is only retained for backwards compatibility.
+.IP \fB\-t\fP 4
+Mark unreadable clusters as bad.
+.IP "\fB\-u\fP \fIPATH\fP" 4
+Try to undelete the specified file.  \fBfsck.fat\fP tries to allocate a chain
+of contiguous unallocated clusters beginning with the start cluster of the
+undeleted file.  This option can be given more than once.
+.IP \fB\-v\fP 4
+Verbose mode.  Generates slightly more output.
+.IP \fB\-V\fP 4
+Perform a verification pass.  The filesystem check is repeated after the
+first run.  The second pass should never report any fixable errors.  It may
+take considerably longer than the first pass, because the first pass may
+have generated long list of modifications that have to be scanned for each
+disk read.
+.IP \fB\-w\fP 4
+Write changes to disk immediately.
+.IP \fB\-y\fP 4
+.\" ----------------------------------------------------------------------------
+Same as \fB\-a\fP (automatically repair filesystem) for compatibility with other
+fsck tools.
+.SH "EXIT STATUS"

+\fBmkfs.fat\fP \- create an MS\-DOS filesystem under Linux
+.SH SYNOPSIS
+.\" ----------------------------------------------------------------------------
+\fBmkfs.fat\fP [\fIOPTIONS\fP] \fIDEVICE\fP [\fIBLOCK\-COUNT\fP]
+.SH DESCRIPTION
+.\" ----------------------------------------------------------------------------
+\fBmkfs.fat\fP is used to create an MS\-DOS filesystem under Linux on a device
+(usually a disk partition).  \fIDEVICE\fP is the special file corresponding to
+the device (e.g. /dev/sdXX).  \fIBLOCK\-COUNT\fP is the number of blocks on the
+device.  If omitted, \fBmkfs.fat\fP automatically determines the filesystem
+size.
+.SH OPTIONS
+.IP \fB\-a\fP 4
+Normally, for any filesystem except very small ones, \fBmkfs.fat\fP will align
+all the data structures to cluster size, to make sure that as long as the
+partition is properly aligned, so will all the data structures in the
+filesystem.  This option disables alignment; this may provide a handful of
+additional clusters of storage at the expense of a significant performance
+degradation on RAIDs, flash media or large\-sector hard disks.
+.IP "\fB \-A\fP" 4
+Use Atari variation of the MS\-DOS filesystem.  This is default if
+\fBmkfs.fat\fP is run on an Atari, then this option turns off Atari format.
+There are some differences when using Atari format: If not directed
+otherwise by the user, \fBmkfs.fat\fP will always use 2 sectors per cluster,
+since GEMDOS doesn't like other values very much.  It will also obey the
+maximum number of sectors GEMDOS can handle.  Larger filesystems are managed
+by raising the logical sector size.  Under Atari format, an Atari\-compatible
+serial number for the filesystem is generated, and a 12 bit FAT is used only
+for filesystems that have one of the usual floppy sizes (720k, 1.2M, 1.44M,
+2.88M), a 16 bit FAT otherwise.  This can be overridden with the \fB\-F\fP
+option.  Some PC\-specific boot sector fields aren't written, and a boot
+message (option \fB\-m\fP) is ignored.
+.IP "\fB\-b\fP \fISECTOR\-OF\-BACKUP\fP" 4
+Selects the location of the backup boot sector for FAT32.  Default depends
+on number of reserved sectors, but usually is sector 6.  The backup must be
+within the range of reserved sectors.
+.IP \fB\-c\fP 4
+Check the device for bad blocks before creating the filesystem.
+.IP \fB\-C\fP 4
+Create the file given as \fIDEVICE\fP on the command line, and write the
+to\-be\-created filesystem to it.  This can be used to create the new
+filesystem in a file instead of on a real device, and to avoid using \fBdd\fP
+in advance to create a file of appropriate size.  With this option, the
+\fIBLOCK\-COUNT\fP must be given, because otherwise the intended size of the
+filesystem wouldn't be known.  The file created is a sparse file, which
+actually only contains the meta\-data areas (boot sector, FATs, and root
+directory).  The data portions won't be stored on the disk, but the file
+nevertheless will have the correct size.  The resulting file can be copied
+later to a floppy disk or other device, or mounted through a loop device.
+.IP "\fB\-D\fP \fIDRIVE\-NUMBER\fP" 4
+Specify the BIOS drive number to be stored in the FAT boot sector.  This
+value is usually 0x80 for hard disks and 0x00 for floppy devices or

+Sets the volume ID of the newly created filesystem; \fIVOLUME\-ID\fP is a 32\-bit

+.\" ----------------------------------------------------------------------------
+.SH SYNOPSIS
+\fBfsck.fat\fR [\fIOPTIONS\fR] \fIDEVICE\fR
+.\" ----------------------------------------------------------------------------
+.SH DESCRIPTION
+\fBfsck.fat\fR verifies the consistency of MS\-DOS filesystems and optionally
+tries to repair them.
+.PP
+The following filesystem problems can be corrected (in this order):
+.IP "*" 4
+FAT contains invalid cluster numbers.
+Cluster is changed to EOF.
+.IP "*" 4
+File's cluster chain contains a loop.
+The loop is broken.
+.IP "*" 4
+Bad clusters (read errors).
+The clusters are marked bad and they are removed from files owning them.
+This check is optional.
+.IP "*" 4
+Directories with a large number of bad entries (probably corrupt).
+The directory can be deleted.
+.IP "*" 4
+Files . and .. are non\-directories.
+They can be deleted or renamed.
+.IP "*" 4
+Directories . and .. in root directory.
+They are deleted.
+.IP "*" 4
+Bad filenames.
+They can be renamed.
+.IP "*" 4
+Duplicate directory entries.
+They can be deleted or renamed.
+.IP "*" 4
+Directories with non\-zero size field.
+Size is set to zero.
+.IP "*" 4
+Directory . does not point to parent directory.
+The start pointer is adjusted.
+.IP "*" 4
+Directory .. does not point to parent of parent directory.
+The start pointer is adjusted.
+.IP "*" 4
+Start cluster number of a file is invalid.
+The file is truncated.
+.IP "*" 4
+File contains bad or free clusters.
+The file is truncated.
+.IP "*" 4
+File's cluster chain is longer than indicated by the size fields.
+The file is truncated.
+.IP "*" 4
+Two or more files share the same cluster(s).
+All but one of the files are truncated.
+If the file being truncated is a directory file that has already been read, the
+filesystem check is restarted after truncation.
+.IP "*" 4
+File's cluster chain is shorter than indicated by the size fields.
+The file is truncated.
+.IP "*" 4
+Clusters are marked as used but are not owned by a file.
+They are marked as free.
+.PP
+Additionally, the following problems are detected, but not repaired:
+.IP "*" 4
+Invalid parameters in boot sector
+.IP "*" 4
+Absence of . and .. entries in non\-root directories
+.PP
+When \fBfsck.fat\fR checks a filesystem, it accumulates all changes in memory
+and performs them only after all checks are complete.
+This can be disabled with the \fB\-w\fR option.
+.\" ----------------------------------------------------------------------------
+.SH OPTIONS
+.IP "\fB\-a\fR" 4
+Automatically repair the filesystem.
+No user intervention is necessary.
+Whenever there is more than one method to solve a problem, the least
+destructive approach is used.
+.IP "\fB\-A\fR" 4
+Use Atari variation of the MS\-DOS filesystem.
+This is default if \fBfsck.fat\fR is run on an Atari, then this option turns
+off Atari format.
+There are some minor differences in Atari format:
+Some boot sector fields are interpreted slightly different, and the special FAT
+entries for end\-of\-file and bad cluster can be different.
+Under MS\-DOS 0xfff8 is used for EOF and Atari employs 0xffff by default, but
+both systems recognize all values from 0xfff8...0xffff as end\-of\-file.
+MS\-DOS uses only 0xfff7 for bad clusters, where on Atari values 0xfff0...0xfff7
+are for this purpose (but the standard value is still 0xfff7).
+.IP "\fB-b\fR" 4
+Make read-only boot sector check.
+.IP "\fB\-d\fR \fIPATH\fR" 4
+Delete the specified file.
+If more than one file with that name exist, the first one is deleted.
+This option can be given more than once.
+.IP "\fB\-f\fR" 4
+Salvage unused cluster chains to files.
+By default, unused clusters are added to the free disk space except in auto mode
+(\fB\-a\fR).
+.IP "\fB\-l\fR" 4
+List path names of files being processed.
+.IP "\fB\-n\fR" 4
+No\-operation mode: non\-interactively check for errors, but don't write
+anything to the filesystem.
+.IP "\fB\-p\fR" 4
+Same as \fB\-a\fR, for compatibility with other *fsck.
+.IP "\fB\-r\fR" 4
+Interactively repair the filesystem.
+The user is asked for advice whenever there is more than one approach to fix an
+inconsistency.
+This is the default mode and the option is only retained for backwards
+compatibility.
+.IP "\fB\-t\fR" 4
+Mark unreadable clusters as bad.
+.IP "\fB\-u\fR \fIPATH\fR" 4
+Try to undelete the specified file.
+\fBfsck.fat\fR tries to allocate a chain of contiguous unallocated clusters
+beginning with the start cluster of the undeleted file.
+This option can be given more than once.
+.IP "\fB\-v\fR" 4
+Verbose mode.
+Generates slightly more output.
+.IP "\fB\-V\fR" 4
+Perform a verification pass.
+The filesystem check is repeated after the first run.
+The second pass should never report any fixable errors.
+It may take considerably longer than the first pass, because the first pass may
+have generated long list of modifications that have to be scanned for each disk
+read.
+.IP "\fB\-w\fR" 4
+Write changes to disk immediately.
+.IP "\fB\-y\fR" 4
+Same as \fB\-a\fR (automatically repair filesystem) for compatibility with other
+fsck tools.
+.\" ----------------------------------------------------------------------------
+.SH "EXIT STATUS"
+.IP "0" 4
+No recoverable errors have been detected.
+.IP "1" 4
+Recoverable errors have been detected or \fBfsck.fat\fR has discovered an
+internal inconsistency.
+.IP "2" 4
+Usage error.
+\fBfsck.fat\fR did not access the filesystem.
+.\" ----------------------------------------------------------------------------
+.SH FILES
+.IP "fsck0000.rec, fsck0001.rec, ..." 4
+When recovering from a corrupted filesystem, \fBfsck.fat\fR dumps recovered data
+into files named 'fsckNNNN.rec' in the top level directory of the filesystem.
+.\" ----------------------------------------------------------------------------
+.SH BUGS
+Does not create . and .. files where necessary.
+Does not remove entirely empty directories.
+Should give more diagnostic messages.

+\fBmkfs.fat\fR \- create an MS-DOS filesystem under Linux
+.\" ----------------------------------------------------------------------------
+.SH SYNOPSIS
+\fBmkfs.fat\fR [\fIOPTIONS\fR] \fIDEVICE\fR [\fIBLOCK-COUNT\fR]
+.\" ----------------------------------------------------------------------------
+.SH DESCRIPTION
+\fBmkfs.fat\fR is used to create an MS-DOS filesystem under Linux on a device
+(usually a disk partition).
+\fIDEVICE\fR is the special file corresponding to the device (e.g. /dev/sdXX).
+\fIBLOCK-COUNT\fR is the number of blocks on the device.
+If omitted, \fBmkfs.fat\fR automatically determines the filesystem size.
+.\" ----------------------------------------------------------------------------
+.SH OPTIONS
+.IP "\fB\-a\fR" 4
+Normally, for any filesystem except very small ones, \fBmkfs.fat\fR will align
+all the data structures to cluster size, to make sure that as long as the
+partition is properly aligned, so will all the data structures in the
+filesystem.
+This option disables alignment; this may provide a handful of additional
+clusters of storage at the expense of a significant performance degradation on
+RAIDs, flash media or large-sector hard disks.
+.IP "\fB \-A\fR" 4
+Use Atari variation of the MS-DOS filesystem.
+This is default if \fBmkfs.fat\fR is run on an Atari, then this option turns off
+Atari format.
+There are some differences when using Atari format:
+If not directed otherwise by the user, \fBmkfs.fat\fR will always use 2 sectors
+per cluster, since GEMDOS doesn't like other values very much.
+It will also obey the maximum number of sectors GEMDOS can handle.
+Larger filesystems are managed by raising the logical sector size.
+Under Atari format, an Atari-compatible serial number for the filesystem is
+generated, and a 12 bit FAT is used only for filesystems that have one of the
+usual floppy sizes (720k, 1.2M, 1.44M, 2.88M), a 16 bit FAT otherwise.
+This can be overridden with the \fB\-F\fR option.
+Some PC-specific boot sector fields aren't written, and a boot message (option
+\fB\-m\fR) is ignored.
+.IP "\fB\-b\fR \fISECTOR-OF-BACKUP\fR" 4
+Selects the location of the backup boot sector for FAT32.
+Default depends on number of reserved sectors, but usually is sector 6.
+The backup must be within the range of reserved sectors.
+.IP "\fB\-c" 4
+Check the device for bad blocks before creating the filesystem.
+.IP "\fB\-C\fR" 4
+Create the file given as \fIDEVICE\fR on the command line, and write the
+to-be-created filesystem to it.
+This can be used to create the new filesystem in a file instead of on a real
+device, and to avoid using \fBdd\fR in advance to create a file of appropriate
+size.
+With this option, the \fIBLOCK-COUNT\fR must be given, because otherwise the
+intended size of the filesystem wouldn't be known.
+The file created is a sparse file, which actually only contains the meta-data
+areas (boot sector, FATs, and root directory).
+The data portions won't be stored on the disk, but the file nevertheless will
+have the correct size.
+The resulting file can be copied later to a floppy disk or other device, or
+mounted through a loop device.
+.IP "\fB\-D\fR \fIDRIVE-NUMBER\fR" 4
+Specify the BIOS drive number to be stored in the FAT boot sector.
+This value is usually 0x80 for hard disks and 0x00 for floppy devices or
+partitions to be used for floppy emulation.
+.IP "\fB\-f\fR \fINUMBER-OF-FATS\fR" 4
+Specify the number of file allocation tables in the filesystem.
+The default is 2.
+.IP "\fB\-F\fR \fIFAT-SIZE\fR" 4
+Specifies the type of file allocation tables used (12, 16 or 32 bit).
+If nothing is specified, \fBmkfs.fat\fR will automatically select between 12, 16

+/* Description: Utility to allow an MS-DOS filesystem to be created
+   under Linux.  A lot of the basic structure of this program has been
+   borrowed from Remy Card's "mke2fs" code.
+
+   As far as possible the aim here is to make the "mkfs.fat" command
+   look almost identical to the other Linux filesystem make utilties,
+   eg bad blocks are still specified as blocks, not sectors, but when
+   it comes down to it, DOS is tied to the idea of a sector (512 bytes
+   as a rule), and not the block.  For example the boot block does not
+   occupy a full cluster.
+
+   Fixes/additions May 1998 by Roman Hodek
+   <Roman.Hodek@informatik.uni-erlangen.de>:
+   - Atari format support
+   - New options -A, -S, -C
+   - Support for filesystems > 2GB
+   - FAT32 support */

+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if

+1.2.2 (2015-11-09)
+
+* Improved reliability in case of a sudden unplug: FS will be in a clean state
+after closing all files and performing sync(1).
+* Fixed compilation on Debian GNU/kFreeBSD and GNU/Hurd platforms.
+* Updated mount.exfat-fuse man page.
+
+1.2.1 (2015-09-24)
+
+* Fixed compatibility with Zalman VE-200: now newly created directories do not
+have archive bit set.
+* Fixed heap corruption: malformed FS can use invalid sector or cluster size.
+* Fixed hang on mount: malformed FS can have cyclic references in the clusters
+map.
+
+1.2.0 (2015-08-26)
+
+* Switched from SCons to autotools.
+* Added musl libc support [Brendan Heading].
+* Worked around "FS is larger than device" error for memory cards formatted by
+Panasonic Lumix cameras.
+* Worked around "unknown entry type 0xe1" error for memory cards formatted by
+Sony cameras.
+
+1.1.1 (2014-11-15)
+
+* Fixed mkfs crash on some sectors-per-cluster (-s option) values.
+
+1.1.0 (2014-07-08)
+
+* Relicensed the project from GPLv3+ to GPLv2+.
+* OpenBSD support [Helg Bredow].
+* Improved I/O errors handling.
+* Implemented fsync() and fsyncdir().
+* Fixed crash on Mac OS X 10.5 caused by non-standard use of realpath(). Also
+fixed TrueCrypt disks unmounting.
+* Avoid extra erase on writes to the end of a file. This should improve linear
+write speed.
+* Allow arbitrary changing of lower 9 bits of mode. Allow owner/group changing
+to the same owner/group. This fixes rsync.
+* Fixed buffers overflows when handling lengthy file names.
+* Fixed "real size does not equal to size" error on volumes with pagefile.sys.
+* Fixed negative IUsed in "df -i" output.
+
+1.0.1 (2013-02-02)
+
+* Fixed unexpected removal of a directory if it is moved into itself.
+* Fixed "Operation not permitted" error on reading an empty file.
+
+1.0.0 (2013-01-19)
+
+* Fixed crash when renaming a file within a single directory and a new name
+differs only in case.
+* Fixed clusters allocation: a cluster beyond valid clusters range could be
+allocated.
+* Fixed crash when a volume is unmounted while some files are open.
+* SConscript now respects AR and RANLIB environment variables.
+* Improved error handling.
+
+Linux:
+
+* Enabled big_writes. This improves write speed (larger block size means less
+switches between kernel- and user-space).
+* Do BLKROGET ioctl to make sure the device is not read-only: after
+"blockdev --setro" kernel still allows to open the device in read-write mode
+but fails writes.
+
+OS X:
+
+* Fixed OS X 10.8 support.
+* Switched to 64-bit inode numbers (now Mac OS X 10.5 or later is required).
+* Switched from unmaintained MacFUSE to OSXFUSE (http://osxfuse.github.com).
+* Fixed device size detection. Now mkfs works.
+* Workarounded some utilities failures due to missing chmod() support.
+* Disabled (senseless) permission checks made by FUSE.
+
+0.9.8 (2012-08-09)
+
+* The mkfs utility can now create huge file systems (up to several exabytes).
+* Fixed handling of characters beyond Basic Multilingual Plane.
+* Echo messages to syslog only if stderr is not connected to a terminal.
+
+0.9.7 (2012-03-08)
+
+* Out-of-the-box FreeBSD support (via ublio library).
+* Fixed "missing EOD entry" error (could happen while reading directory that
+consists of several clusters).
+* Fixed interpretation of minutes field in files timestamps (minutes could be
+displayed incorrectly).
+* Fixed mtime seconds field initialization for newly created file (mtime could
+be 1 sec less than creation time).
+* SConscript now respects CC, CCFLAGS and LDFLAGS environment variables.
+
+0.9.6 (2012-01-14)
+
+* Fixed write performance regression introduced in 0.9.4.
+* Mount in read-only mode if the device is write-protected.
+* Set ctime to mtime to ensure we don't break programs that rely on ctime
+(e.g. rsync considered that all files are outdated) [Eldad Zack].
+* Indicate that FS in not clean when it was not cleanly unmounted.
+* Utilities are now compatible with GNU/Hurd.
+* Fixed several memory leaks that could occur on error handling paths.
+* Improved handling of corrupted file systems.
+
+0.9.5 (2011-05-15)
+
+* Fixed erasing of the root directory cluster when creating a new FS with
+mkexfatfs. This bug could cause mkexfatfs to produce invalid FS.
+* Utilities are not linked with libfuse anymore.
+* Ensure that the path being opened is either a device or a regular file.
+
+0.9.4 (2011-03-05)
+
+* Introduced exfat-utils: dumpexfat, exfatfsck, mkexfatfs, exfatlabel.
+* Fixed "Invalid argument" error while mounting a volume from a disk with sector size greater than 512 bytes.
+* Wait for all data to be flushed to disk on unmount.
+* Kernel cache is no longer flushed on open. This can slightly improve read performance by avoiding extra read requests from kernel to user-space.
+* Allow to unmount volumes as user (fusermount -u) if they were mounted from the very same user [Tino Lange].
+* Errors and warnings are now duplicated to syslog.
+
+0.9.3 (2010-09-25)
+
+* Directories now can shrink.
+* Improved timestamps resolution from 2 sec to 1 sec.
+* Fixed timestamps displaying under Mac OS X when compiled for i386 or ppc.
+* Fixed FS size displaying for non-GNU systems.
+
+0.9.2 (2010-07-24)
+
+* Fixed a bug which could cause the whole directory to become unreadable after renaming a file in it.
+* Support for Solaris and various *BSD [Albert Lee].
+* Improved error handling on corrupted volumes.
+* Improved allowed file name characters filter.
+* Added man page.
+
+0.9.1 (2010-06-12)
+
+* Implemented automounting (util-linux-ng 2.18 or later is required).
+* Fixed mounting when cluster bitmap is larger than expected.
+* Fixed crash on statfs() when root directory contains error.
+* Fixed bugs specific to big-endian machines.
+* Other bugfixes.
+
+0.9.0 (2010-03-21)
+
+* Initial release.

+About
+-----
+
+This project aims to provide a full-featured [exFAT][1] file system implementation for Unix-like systems. It consists of a [FUSE][2] module (fuse-exfat) and a set of utilities (exfat-utils).
+
+Supported operating systems:
+
+* GNU/Linux
+* Mac OS X 10.5 or later
+* FreeBSD
+* OpenBSD
+
+Most GNU/Linux distributions already have fuse-exfat and exfat-utils in their repositories, so you can just install and use them. The next chapter describes how to compile them from source.
+
+Compiling
+---------
+
+To build this project under GNU/Linux you need to install the following packages:
+
+* git
+* autoconf
+* automake
+* pkg-config
+* fuse-devel (or libfuse-dev)
+* gcc
+* make
+
+Get the source code, change directory and compile:
+
+    git clone https://github.com/relan/exfat.git
+    cd exfat
+    autoreconf --install
+    ./configure --prefix=/usr
+    make
+
+Then install driver and utilities:
+
+    sudo make install
+
+You can remove them using this command:
+
+    sudo make uninstall
+
+Mounting
+--------
+
+Modern GNU/Linux distributions will mount exFAT volumes automatically—util-linux-ng 2.18 (was renamed to util-linux in 2.19) is required for this. Anyway, you can mount manually (you will need root privileges):
+
+    sudo mount.exfat-fuse /dev/sdXn /mnt/exfat
+
+where /dev/sdXn is the partition special file, /mnt/exfat is a mountpoint.
+
+Feedback
+--------
+
+If you have any questions, issues, suggestions, bug reports, etc. please create an [issue][3]. Pull requests are also welcome!

+
+.SH BUGS
+exFAT is a case-insensitive file system. Some things can behave unexpectedly,
+e.g. directory renaming that changes only case of some characters:
+
+.B \t$ mv FOO Foo
+.br
+.B \tmv: cannot move \(cqFOO\(cq to a subdirectory of itself, \(cqFoo/FOO\(cq
+
+This happens because
+.B mv
+finds that destination exists (for case-insensitive file
+systems
+.B FOO
+and
+.B Foo
+are the same thing) and adds source basename to the destination. The file
+system gets
+.B rename(\(dqFOO\(dq,\ \(dqFoo/FOO\(dq)
+syscall and returns an error.

+.TH EXFATLABEL 8 "February 2011"
+.SH NAME
+.B exfatlabel
+\- get or set an exFAT file system label
+.SH SYNOPSIS
+.B exfatlabel
+[
+.B \-V
+]
+.I device
+[
+.I label
+]
+
+.SH DESCRIPTION
+.B exfatlabel
+reads or changes an exFAT file system label (volume name).
+
+If
+.I label
+argument is present,
+.B exfatlabel
+sets the new volume name. Label can be up to 15 characters. This limit is
+shorter if characters beyond Unicode BMP are used because internally label
+is stored in UTF-16.
+
+If
+.I label
+argument is omitted,
+.B exfatlabel
+just prints current volume name.
+
+.SH COMMAND LINE OPTIONS
+Command line options available:
+.TP
+.BI \-V
+Print version and copyright.
+
+.SH EXIT CODES
+Zero is returned on success. Any other code means an error.

+.SH NAME
+.B mkexfatfs
+\- create an exFAT file system
+.SH SYNOPSIS
+.B mkexfatfs
+[
+.B \-i
+.I volume-id
+]
+[
+.B \-n
+.I volume-name
+]
+[
+.B \-p
+.I partition-first-sector
+]
+[
+.B \-s
+.I sectors-per-cluster
+]
+[
+.B \-V
+]
+.I device
+
+.SH DESCRIPTION
+.B mkexfatfs
+creates an exFAT file system on a block device.
+.I device
+is a special file corresponding to the partition on the device. Note that if
+this is an MBR partition then the file system type should be set to 0x07
+(NTFS/exFAT) otherwise other operating systems may refuse to mount the
+file system.
+
+.SH OPTIONS
+Command line options available:
+.TP
+.BI \-i " volume-id"
+A 32-bit hexadecimal number. By default a value based on current time is set.
+.TP
+.BI \-n " volume-name"
+Volume name (label), up to 15 characters. By default no label is set.
+.TP
+.BI \-p " partition-first-sector"
+First sector of the partition starting from the beginning of the whole disk.
+exFAT super block has a field for this value but in fact it's optional and
+does not affect anything. Default is 0.
+.TP
+.BI \-s " sectors-per-cluster"
+Number of physical sectors per cluster (cluster is an allocation unit in
+exFAT). Must be a power of 2, i.e. 1, 2, 4, 8, etc. Cluster size can not
+exceed 32 MB. Default cluster sizes are:
+4 KB if volume size is less than 256 MB,
+32 KB if volume size is from 256 MB to 32 GB,
+128 KB if volume size is 32 GB or larger.
+.TP
+.BI \-V
+Print version and copyright.
+
+.SH EXIT CODES
+Zero is returned on successful creation. Any other code means an error.

+ *   Henceforth the source version will match the shared-library major
+ *   and minor numbers; the shared-library major version number will be
+ *   used for changes in backward compatibility, as it is intended.  The
+ *   PNG_LIBPNG_VER macro, which is not used within libpng but is available
+ *   for applications, is an unsigned integer of the form xyyzz corresponding
+ *   to the source version x.y.z (leading zeros in y and z).  Beta versions
+ *   were given the previous public release number plus a letter, until
+ *   version 1.0.6j; from then on they were given the upcoming public
+ *   release number plus "betaNN" or "rcNN".
+ *
+ *   Binary incompatibility exists only when applications make direct access
+ *   to the info_ptr or png_ptr members through png.h, and the compiled
+ *   application is loaded with a different version of the library.
+ *
+ *   DLLNUM will change each time there are forward or backward changes
+ *   in binary compatibility (e.g., when a new feature is added).
+ *
+ * See libpng-manual.txt or libpng.3 for more information.  The PNG
+ * specification is available as a W3C Recommendation and as an ISO
+ * Specification, <http://www.w3.org/TR/2003/REC-PNG-20031110/

+ * Y2K compliance in libpng:
+ * =========================
+ *
+ *    March 28, 2013
+ *
+ *    Since the PNG Development group is an ad-hoc body, we can't make
+ *    an official declaration.
+ *
+ *    This is your unofficial assurance that libpng from version 0.71 and
+ *    upward through 1.6.1 are Y2K compliant.  It is my belief that
+ *    earlier versions were also Y2K compliant.
+ *
+ *    Libpng only has two year fields.  One is a 2-byte unsigned integer
+ *    that will hold years up to 65535.  The other, which is deprecated,
+ *    holds the date in text format, and will hold years up to 9999.
+ *
+ *    The integer is
+ *        "png_uint_16 year" in png_time_struct.
+ *
+ *    The string is
+ *        "char time_buffer[29]" in png_struct.  This is no longer used
+ *    in libpng-1.6.x and will be removed from libpng-1.7.0.
+ *
+ *    There are seven time-related functions:
+ *        png.c: png_convert_to_rfc_1123_buffer() in png.c
+ *          (formerly png_convert_to_rfc_1123() prior to libpng-1.5.x and
+ *          png_convert_to_rfc_1152() in error prior to libpng-0.98)
+ *        png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
+ *        png_convert_from_time_t() in pngwrite.c
+ *        png_get_tIME() in pngget.c
+ *        png_handle_tIME() in pngrutil.c, called in pngread.c
+ *        png_set_tIME() in pngset.c
+ *        png_write_tIME() in pngwutil.c, called in pngwrite.c
+ *
+ *    All handle dates properly in a Y2K environment.  The
+ *    png_convert_from_time_t() function calls gmtime() to convert from system
+ *    clock time, which returns (year - 1900), which we properly convert to
+ *    the full 4-digit year.  There is a possibility that libpng applications
+ *    are not passing 4-digit years into the png_convert_to_rfc_1123_buffer()
+ *    function, or that they are incorrectly passing only a 2-digit year
+ *    instead of "year - 1900" into the png_convert_from_struct_tm() function,
+ *    but this is not under our control.  The libpng documentation has always
+ *    stated that it works with 4-digit years, and the APIs have been
+ *    documented as such.
+ *
+ *    The tIME chunk itself is also Y2K compliant.  It uses a 2-byte unsigned
+ *    integer to hold the year, and can hold years as large as 65535.
+ *
+ *    zlib, upon which libpng depends, is also Y2K compliant.  It contains
+ *    no date-related code.

+ *
+ * This has no effect on the way pixels are written into a PNG output
+ * datastream. The color samples in a PNG datastream are never premultiplied
+ * with the alpha samples.
+ *
+ * The default is to return data according to the PNG specification: the alpha
+ * channel is a linear measure of the contribution of the pixel to the
+ * corresponding composited pixel.  The gamma encoded color channels must be
+ * scaled according to the contribution and to do this it is necessary to undo
+ * the encoding, scale the color values, perform the composition and reencode
+ * the values.  This is the 'PNG' mode.
+ *
+ * The alternative is to 'associate' the alpha with the color information by
+ * storing color channel values that have been scaled by the alpha.  The
+ * advantage is that the color channels can be resampled (the image can be
+ * scaled) in this form.  The disadvantage is that normal practice is to store
+ * linear, not (gamma) encoded, values and this requires 16-bit channels for
+ * still images rather than the 8-bit channels that are just about sufficient if
+ * gamma encoding is used.  In addition all non-transparent pixel values,
+ * including completely opaque ones, must be gamma encoded to produce the final
+ * image.  This is the 'STANDARD', 'ASSOCIATED' or 'PREMULTIPLIED' mode (the
+ * latter being the two common names for associated alpha color channels.)
+ *
+ * Since it is not necessary to perform arithmetic on opaque color values so
+ * long as they are not to be resampled and are in the final color space it is
+ * possible to optimize the handling of alpha by storing the opaque pixels in
+ * the PNG format (adjusted for the output color space) while storing partially
+ * opaque pixels in the standard, linear, format.  The accuracy required for
+ * standard alpha composition is relatively low, because the pixels are
+ * isolated, therefore typically the accuracy loss in storing 8-bit linear
+ * values is acceptable.  (This is not true if the alpha channel is used to
+ * simulate transparency over large areas - use 16 bits or the PNG mode in
+ * this case!)  This is the 'OPTIMIZED' mode.  For this mode a pixel is
+ * treated as opaque only if the alpha value is equal to the maximum value.
+ *
+ * The final choice is to gamma encode the alpha channel as well.  This is
+ * broken because, in practice, no implementation that uses this choice
+ * correctly undoes the encoding before handling alpha composition.  Use this
+ * choice only if other serious errors in the software or hardware you use
+ * mandate it; the typical serious error is for dark halos to appear around
+ * opaque areas of the composited PNG image because of arithmetic overflow.

+ * When the standard Porter Duff handling is requested with mode 1 the output
+ * encoding is set to be linear and the output_gamma value is only relevant
+ * as a default for input data that has no gamma information.  The linear output
+ * encoding will be overridden if png_set_gamma() is called - the results may be
+ * highly unexpected!
+ *
+ * The following numbers are derived from the sRGB standard and the research
+ * behind it.  sRGB is defined to be approximated by a PNG gAMA chunk value of
+ * 0.45455 (1/2.2) for PNG.  The value implicitly includes any viewing
+ * correction required to take account of any differences in the color
+ * environment of the original scene and the intended display environment; the
+ * value expresses how to *decode* the image for display, not how the original
+ * data was *encoded*.
+ *
+ * sRGB provides a peg for the PNG standard by defining a viewing environment.
+ * sRGB itself, and earlier TV standards, actually use a more complex transform
+ * (a linear portion then a gamma 2.4 power law) than PNG can express.  (PNG is
+ * limited to simple power laws.)  By saying that an image for direct display on
+ * an sRGB conformant system should be stored with a gAMA chunk value of 45455
+ * (11.3.3.2 and 11.3.3.5 of the ISO PNG specification) the PNG specification
+ * makes it possible to derive values for other display systems and
+ * environments.
+ *
+ * The Mac value is deduced from the sRGB based on an assumption that the actual
+ * extra viewing correction used in early Mac display systems was implemented as
+ * a power 1.45 lookup table.
+ *
+ * Any system where a programmable lookup table is used or where the behavior of
+ * the final display device characteristics can be changed requires system
+ * specific code to obtain the current characteristic.  However this can be
+ * difficult and most PNG gamma correction only requires an approximate value.
+ *
+ * By default, if png_set_alpha_mode() is not called, libpng assumes that all
+ * values are unencoded, linear, values and that the output device also has a
+ * linear characteristic.  This is only very rarely correct - it is invariably
+ * better to call png_set_alpha_mode() with PNG_DEFAULT_sRGB than rely on the
+ * default if you don't know what the right answer is!
+ *
+ * The special value PNG_GAMMA_MAC_18 indicates an older Mac system (pre Mac OS
+ * 10.6) which used a correction table to implement a somewhat lower gamma on an
+ * otherwise sRGB system.
+ *
+ * Both these values are reserved (not simple gamma values) in order to allow
+ * more precise correction internally in the future.
+ *
+ * NOTE: the following values can be passed to either the fixed or floating
+ * point APIs, but the floating point API will also accept floating point
+ * values.

+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_DEFAULT_sRGB);
+ *    This is the default libpng handling of the alpha channel - it is not
+ *    pre-multiplied into the color components.  In addition the call states
+ *    that the output is for a sRGB system and causes all PNG files without gAMA
+ *    chunks to be assumed to be encoded using sRGB.
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
+ *    In this case the output is assumed to be something like an sRGB conformant
+ *    display preceeded by a power-law lookup table of power 1.45.  This is how
+ *    early Mac systems behaved.
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_STANDARD, PNG_GAMMA_LINEAR);
+ *    This is the classic Jim Blinn approach and will work in academic
+ *    environments where everything is done by the book.  It has the shortcoming
+ *    of assuming that input PNG data with no gamma information is linear - this
+ *    is unlikely to be correct unless the PNG files where generated locally.
+ *    Most of the time the output precision will be so low as to show
+ *    significant banding in dark areas of the image.
+ *
+ * png_set_expand_16(pp);
+ * png_set_alpha_mode(pp, PNG_ALPHA_STANDARD, PNG_DEFAULT_sRGB);
+ *    This is a somewhat more realistic Jim Blinn inspired approach.  PNG files
+ *    are assumed to have the sRGB encoding if not marked with a gamma value and
+ *    the output is always 16 bits per component.  This permits accurate scaling
+ *    and processing of the data.  If you know that your input PNG files were
+ *    generated locally you might need to replace PNG_DEFAULT_sRGB with the
+ *    correct value for your system.
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_OPTIMIZED, PNG_DEFAULT_sRGB);
+ *    If you just need to composite the PNG image onto an existing background
+ *    and if you control the code that does this you can use the optimization
+ *    setting.  In this case you just copy completely opaque pixels to the
+ *    output.  For pixels that are not completely transparent (you just skip
+ *    those) you do the composition math using png_composite or png_composite_16
+ *    below then encode the resultant 8-bit or 16-bit values to match the output
+ *    encoding.
+ *
+ * Other cases
+ *    If neither the PNG nor the standard linear encoding work for you because
+ *    of the software or hardware you use then you have a big problem.  The PNG
+ *    case will probably result in halos around the image.  The linear encoding
+ *    will probably result in a washed out, too bright, image (it's actually too
+ *    contrasty.)  Try the ALPHA_OPTIMIZED mode above - this will probably
+ *    substantially reduce the halos.  Alternatively try:
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_BROKEN, PNG_DEFAULT_sRGB);
+ *    This option will also reduce the halos, but there will be slight dark
+ *    halos round the opaque parts of the image where the background is light.
+ *    In the OPTIMIZED mode the halos will be light halos where the background
+ *    is dark.  Take your pick - the halos are unavoidable unless you can get
+ *    your hardware/software fixed!  (The OPTIMIZED approach is slightly
+ *    faster.)
+ *
+ * When the default gamma of PNG files doesn't match the output gamma.
+ *    If you have PNG files with no gamma information png_set_alpha_mode allows
+ *    you to provide a default gamma, but it also sets the ouput gamma to the
+ *    matching value.  If you know your PNG files have a gamma that doesn't
+ *    match the output you can take advantage of the fact that
+ *    png_set_alpha_mode always sets the output gamma but only sets the PNG
+ *    default if it is not already set:
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_DEFAULT_sRGB);
+ * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
+ *    The first call sets both the default and the output gamma values, the
+ *    second call overrides the output gamma without changing the default.  This
+ *    is easier than achieving the same effect with png_set_gamma.  You must use
+ *    PNG_ALPHA_PNG for the first call - internal checking in png_set_alpha will
+ *    fire if more than one call to png_set_alpha_mode and png_set_background is
+ *    made in the same read operation, however multiple calls with PNG_ALPHA_PNG
+ *    are ignored.

+/* Provide the default handling for all unknown chunks or, optionally, for

+ *
+ * NOTE: prior to 1.6.0 the handling specified for particular chunks on read was
+ * ignored and the default was used, the per-chunk setting only had an effect on
+ * write.  If you wish to have chunk-specific handling on read in code that must
+ * work on earlier versions you must use a user chunk callback to specify the
+ * desired handling (keep or discard.)
+ *
+ * The 'keep' parameter is a PNG_HANDLE_CHUNK_ value as listed below.  The
+ * parameter is interpreted as follows:
+ *
+ * READ:
+ *    PNG_HANDLE_CHUNK_AS_DEFAULT:
+ *       Known chunks: do normal libpng processing, do not keep the chunk (but
+ *          see the comments below about PNG_HANDLE_AS_UNKNOWN_SUPPORTED)
+ *       Unknown chunks: for a specific chunk use the global default, when used
+ *          as the default discard the chunk data.
+ *    PNG_HANDLE_CHUNK_NEVER:
+ *       Discard the chunk data.
+ *    PNG_HANDLE_CHUNK_IF_SAFE:
+ *       Keep the chunk data if the chunk is not critical else raise a chunk
+ *       error.
+ *    PNG_HANDLE_CHUNK_ALWAYS:
+ *       Keep the chunk data.
+ *
+ * If the chunk data is saved it can be retrieved using png_get_unknown_chunks,
+ * below.  Notice that specifying "AS_DEFAULT" as a global default is equivalent
+ * to specifying "NEVER", however when "AS_DEFAULT" is used for specific chunks
+ * it simply resets the behavior to the libpng default.
+ *
+ * INTERACTION WTIH USER CHUNK CALLBACKS:
+ * The per-chunk handling is always used when there is a png_user_chunk_ptr
+ * callback and the callback returns 0; the chunk is then always stored *unless*
+ * it is critical and the per-chunk setting is other than ALWAYS.  Notice that
+ * the global default is *not* used in this case.  (In effect the per-chunk
+ * value is incremented to at least IF_SAFE.)
+ *
+ * IMPORTANT NOTE: this behavior will change in libpng 1.7 - the global and
+ * per-chunk defaults will be honored.  If you want to preserve the current
+ * behavior when your callback returns 0 you must set PNG_HANDLE_CHUNK_IF_SAFE
+ * as the default - if you don't do this libpng 1.6 will issue a warning.
+ *
+ * If you want unhandled unknown chunks to be discarded in libpng 1.6 and
+ * earlier simply return '1' (handled).
+ *
+ * PNG_HANDLE_AS_UNKNOWN_SUPPORTED:
+ *    If this is *not* set known chunks will always be handled by libpng and
+ *    will never be stored in the unknown chunk list.  Known chunks listed to
+ *    png_set_keep_unknown_chunks will have no effect.  If it is set then known
+ *    chunks listed with a keep other than AS_DEFAULT will *never* be processed
+ *    by libpng, in addition critical chunks must either be processed by the
+ *    callback or saved.
+ *
+ *    The IHDR and IEND chunks must not be listed.  Because this turns off the
+ *    default handling for chunks that would otherwise be recognized the
+ *    behavior of libpng transformations may well become incorrect!
+ *
+ * WRITE:
+ *    When writing chunks the options only apply to the chunks specified by
+ *    png_set_unknown_chunks (below), libpng will *always* write known chunks
+ *    required by png_set_ calls and will always write the core critical chunks
+ *    (as required for PLTE).
+ *
+ *    Each chunk in the png_set_unknown_chunks list is looked up in the
+ *    png_set_keep_unknown_chunks list to find the keep setting, this is then
+ *    interpreted as follows:
+ *
+ *    PNG_HANDLE_CHUNK_AS_DEFAULT:
+ *       Write safe-to-copy chunks and write other chunks if the global
+ *       default is set to _ALWAYS, otherwise don't write this chunk.
+ *    PNG_HANDLE_CHUNK_NEVER:
+ *       Do not write the chunk.
+ *    PNG_HANDLE_CHUNK_IF_SAFE:
+ *       Write the chunk if it is safe-to-copy, otherwise do not write it.
+ *    PNG_HANDLE_CHUNK_ALWAYS:
+ *       Write the chunk.
+ *
+ * Note that the default behavior is effectively the opposite of the read case -
+ * in read unknown chunks are not stored by default, in write they are written
+ * by default.  Also the behavior of PNG_HANDLE_CHUNK_IF_SAFE is very different
+ * - on write the safe-to-copy bit is checked, on read the critical bit is
+ * checked and on read if the chunk is critical an error will be raised.
+ *
+ * num_chunks:
+ * ===========
+ *    If num_chunks is positive, then the "keep" parameter specifies the manner
+ *    for handling only those chunks appearing in the chunk_list array,
+ *    otherwise the chunk list array is ignored.
+ *
+ *    If num_chunks is 0 the "keep" parameter specifies the default behavior for
+ *    unknown chunks, as described above.
+ *
+ *    If num_chunks is negative, then the "keep" parameter specifies the manner
+ *    for handling all unknown chunks plus all chunks recognized by libpng
+ *    except for the IHDR, PLTE, tRNS, IDAT, and IEND chunks (which continue to

+ *  SIMPLIFIED API
+ *******************************************************************************
+ *
+ * Please read the documentation in libpng-manual.txt (TODO: write said
+ * documentation) if you don't understand what follows.
+ *
+ * The simplified API hides the details of both libpng and the PNG file format
+ * itself.  It allows PNG files to be read into a very limited number of
+ * in-memory bitmap formats or to be written from the same formats.  If these
+ * formats do not accomodate your needs then you can, and should, use the more
+ * sophisticated APIs above - these support a wide variety of in-memory formats
+ * and a wide variety of sophisticated transformations to those formats as well
+ * as a wide variety of APIs to manipulate ancillary information.
+ *
+ * To read a PNG file using the simplified API:
+ *
+ * 1) Declare a 'png_image' structure (see below) on the stack and set the
+ *    version field to PNG_IMAGE_VERSION.
+ * 2) Call the appropriate png_image_begin_read... function.
+ * 3) Set the png_image 'format' member to the required sample format.
+ * 4) Allocate a buffer for the image and, if required, the color-map.
+ * 5) Call png_image_finish_read to read the image and, if required, the
+ *    color-map into your buffers.
+ *
+ * There are no restrictions on the format of the PNG input itself; all valid
+ * color types, bit depths, and interlace methods are acceptable, and the
+ * input image is transformed as necessary to the requested in-memory format
+ * during the png_image_finish_read() step.  The only caveat is that if you
+ * request a color-mapped image from a PNG that is full-color or makes
+ * complex use of an alpha channel the transformation is extremely lossy and the
+ * result may look terrible.
+ *
+ * To write a PNG file using the simplified API:
+ *
+ * 1) Declare a 'png_image' structure on the stack and memset() it to all zero.
+ * 2) Initialize the members of the structure that describe the image, setting
+ *    the 'format' member to the format of the image samples.
+ * 3) Call the appropriate png_image_write... function with a pointer to the
+ *    image and, if necessary, the color-map to write the PNG data.
+ *
+ * png_image is a structure that describes the in-memory format of an image
+ * when it is being read or defines the in-memory format of an image that you
+ * need to write:

+ * 2: A gray/luminance channel and an alpha channel (GA).
+ * 3: Three red, green, blue color channels (RGB).
+ * 4: Three color channels and an alpha channel (RGBA).
+ *
+ * The components are encoded in one of two ways:
+ *
+ * a) As a small integer, value 0..255, contained in a single byte.  For the
+ * alpha channel the original value is simply value/255.  For the color or
+ * luminance channels the value is encoded according to the sRGB specification
+ * and matches the 8-bit format expected by typical display devices.
+ *
+ * The color/gray channels are not scaled (pre-multiplied) by the alpha
+ * channel and are suitable for passing to color management software.
+ *
+ * b) As a value in the range 0..65535, contained in a 2-byte integer.  All
+ * channels can be converted to the original value by dividing by 65535; all
+ * channels are linear.  Color channels use the RGB encoding (RGB end-points) of
+ * the sRGB specification.  This encoding is identified by the
+ * PNG_FORMAT_FLAG_LINEAR flag below.
+ *
+ * When the simplified API needs to convert between sRGB and linear colorspaces,
+ * the actual sRGB transfer curve defined in the sRGB specification (see the
+ * article at http://en.wikipedia.org/wiki/SRGB) is used, not the gamma=1/2.2
+ * approximation used elsewhere in libpng.
+ *
+ * When an alpha channel is present it is expected to denote pixel coverage
+ * of the color or luminance channels and is returned as an associated alpha
+ * channel: the color/gray channels are scaled (pre-multiplied) by the alpha
+ * value.
+ *
+ * The samples are either contained directly in the image data, between 1 and 8
+ * bytes per pixel according to the encoding, or are held in a color-map indexed
+ * by bytes in the image data.  In the case of a color-map the color-map entries
+ * are individual samples, encoded as above, and the image data has one byte per
+ * pixel to select the relevant sample from the color-map.
+ */

+/* PNG_FORMAT_*
+ *
+ * #defines to be used in png_image::format.  Each #define identifies a
+ * particular layout of sample data and, if present, alpha values.  There are
+ * separate defines for each of the two component encodings.
+ *
+ * A format is built up using single bit flag values.  All combinations are
+ * valid.  Formats can be built up from the flag values or you can use one of
+ * the predefined values below.  When testing formats always use the FORMAT_FLAG
+ * macros to test for individual features - future versions of the library may
+ * add new flags.
+ *
+ * When reading or writing color-mapped images the format should be set to the

+/* Function calling conventions.
+ * =============================
+ * Normally it is not necessary to specify to the compiler how to call
+ * a function - it just does it - however on x86 systems derived from
+ * Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems
+ * and some others) there are multiple ways to call a function and the
+ * default can be changed on the compiler command line.  For this reason
+ * libpng specifies the calling convention of every exported function and
+ * every function called via a user supplied function pointer.  This is
+ * done in this file by defining the following macros:
+ *
+ * PNGAPI    Calling convention for exported functions.
+ * PNGCBAPI  Calling convention for user provided (callback) functions.
+ * PNGCAPI   Calling convention used by the ANSI-C library (required
+ *           for longjmp callbacks and sometimes used internally to
+ *           specify the calling convention for zlib).
+ *
+ * These macros should never be overridden.  If it is necessary to
+ * change calling convention in a private build this can be done
+ * by setting PNG_API_RULE (which defaults to 0) to one of the values
+ * below to select the correct 'API' variants.
+ *
+ * PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.
+ *                This is correct in every known environment.
+ * PNG_API_RULE=1 Use the operating system convention for PNGAPI and
+ *                the 'C' calling convention (from PNGCAPI) for
+ *                callbacks (PNGCBAPI).  This is no longer required
+ *                in any known environment - if it has to be used
+ *                please post an explanation of the problem to the
+ *                libpng mailing list.
+ *
+ * These cases only differ if the operating system does not use the C
+ * calling convention, at present this just means the above cases
+ * (x86 DOS/Windows sytems) and, even then, this does not apply to
+ * Cygwin running on those systems.
+ *
+ * Note that the value must be defined in pnglibconf.h so that what
+ * the application uses to call the library matches the conventions
+ * set when building the library.
+ */
+
+/* Symbol export
+ * =============
+ * When building a shared library it is almost always necessary to tell
+ * the compiler which symbols to export.  The png.h macro 'PNG_EXPORT'
+ * is used to mark the symbols.  On some systems these symbols can be
+ * extracted at link time and need no special processing by the compiler,
+ * on other systems the symbols are flagged by the compiler and just
+ * the declaration requires a special tag applied (unfortunately) in a
+ * compiler dependent way.  Some systems can do either.
+ *
+ * A small number of older systems also require a symbol from a DLL to
+ * be flagged to the program that calls it.  This is a problem because
+ * we do not know in the header file included by application code that
+ * the symbol will come from a shared library, as opposed to a statically
+ * linked one.  For this reason the application must tell us by setting
+ * the magic flag PNG_USE_DLL to turn on the special processing before
+ * it includes png.h.
+ *
+ * Four additional macros are used to make this happen:
+ *
+ * PNG_IMPEXP The magic (if any) to cause a symbol to be exported from
+ *            the build or imported if PNG_USE_DLL is set - compiler
+ *            and system specific.
+ *
+ * PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to
+ *                       'type', compiler specific.
+ *
+ * PNG_DLL_EXPORT Set to the magic to use during a libpng build to
+ *                make a symbol exported from the DLL.  Not used in the
+ *                public header files; see pngpriv.h for how it is used
+ *                in the libpng build.
+ *
+ * PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come
+ *                from a DLL - used to define PNG_IMPEXP when
+ *                PNG_USE_DLL is set.
+ */
+
+/* System specific discovery.
+ * ==========================
+ * This code is used at build time to find PNG_IMPEXP, the API settings
+ * and PNG_EXPORT_TYPE(), it may also set a macro to indicate the DLL
+ * import processing is possible.  On Windows systems it also sets

+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+	later.  Patch by Anatol Pomozov
+
+2012-05-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Linking to a library that uses threads requires the application
+	to be linked with -pthreads otherwise some pthread functions will

+	file or directory is deleted.  Patch by John Muir
+
+2011-12-06  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Update retrieve_reply() method
+
+2011-12-05  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Low level API: lock argument of fuse_reply_lock should have a
+	'const' qualifier.  Reported by Shachar Sharon
+
+	* Add support for ioctl on directories.  Reported by Antonio SJ
+	Musumeci
+
+2011-10-13  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Reply to request with ENOMEM in case of failure to allocate
+	request structure.  Otherwise the task issuing the request will
+	just freeze up until the filesystem daemon is killed.  Reported by
+	Stephan Kulow
+
+2011-09-23  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Replace daemon() function with fork().  Patch by Anatol Pomozov
+
+2011-08-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* If configured with --disable-mtab then don't call mount(8) from
+	libfuse to update the mtab.  Reported by: James Sierp
+
+2011-08-24  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Use LRU list for cleaning up the cache if the "remember=T"
+	option was given.  Patch by therealneworld@gmail.com
+
+2011-07-06  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add ->flock() operation to low and high level interfaces.  This
+	fixes problems with emulating flock() with POSIX locking.
+	Reported by Sebastian Pipping.  As with lock/setlk/getlk most
+	filesystems don't need to implement this, as the kernel takes care
+	of file locking.  The only reason to implement locking operations
+	is for network filesystems which want file locking to work between
+	clients.
+
+2011-07-02  Sebastian Pipping <sebastian@pipping.org>
+
+	* Make xmp_utimens of examples "fusexmp" and "fusexmp_fh"
+	not follow symlinks as other layers do that already.
+
+2011-06-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add "remember" option.  This works similar to "noforget" except
+	that eventually the node will be allowed to expire from the cache.
+	Patch by therealneworld@gmail.com
+
+2011-05-27  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Check if splice/vmsplice are supported
+
+2011-05-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Remove -lrt -ldl from fuse.pc for dynamic linking since
+	libfuse.so is already linked with these libraries.  Reported by:
+	Nikolaus Rath
+
+2011-05-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Cleaner build output.  Patch by Reuben Hawkins
+
+2011-05-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Disable splice by default, add "splice_read", "splice_write" and
+	"splice_move" options.  Keep the "no_splice_*" variants, which can
+	disable splice even if the filesystem explicitly enables it.
+
+2011-04-15  Max Krasnyansky <maxk@kernel.org>
+	* Added support for "auto_unmount" option which unmounts the
+	filesystem automatically on process exit (or crash).
+
+2011-03-30  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Patches by Laszlo Papp fixing various issues found by the
+	Coverity checker
+
+2011-03-11  Miklos Szeredi <miklos@szeredi.hu>
+
+	* In case of failure to add to /etc/mtab don't umount.  Reported
+	by Marc Deslauriers
+
+2011-02-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* libfuse: In fuse_session_loop_mt() don't pause when exiting the
+	worker threads.  The pause() was added in 2.2.1 to prevent
+	segfault on pthread_cancel() on an exited, detached thread.  Now
+	worker threads are not detached and pthread_cancel() should work
+	fine even after the thread exited.  Reported by Boris Protopopov
+
+2011-01-31  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fusermount: chdir to / before performing mount/umount
+
+	* fusermount: only allow mount and umount if util-linux supports
+	--no-canonicalize
+
+2010-12-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Highlevel lib: allow hash tables to shrink
+
+	* Highlevel lib: add slab allocation for node cache.  This will
+	allow the memory used by the filesystem to grow and shrink
+	depending on how many inodes are currently cached.
+
+2010-12-13  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Highlevel lib: use dynamically resized hash table for looking up
+	by name and node ID.
+
+2010-12-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Allow batching of forget requests.  This allows forget requests
+	to be processed faster and doesn't require a modification to fuse
+	filesystems.  Reported by Terje Malmedal
+
+	* Add ->forget_multi() operation to the lowlevel API.  The
+	filesystem may implement this to process multiple forget requests
+	in one call
+
+	* Fix the ambiguity of ioctl ABI on the kernel/userspace boundary
+	for 32bit vs. 64bit userspace
+
+2010-11-10  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add new write_buf() method to the highlevel API.  Similarly to
+	the lowlevel write_buf() method, this allows implementing zero
+	copy writes.
+
+	* Add a new read_buf() method to the highlevel API.  This allows
+	returning a generic buffer from the read method, which in turn
+	allows zero copy reads.
+
+	* In fusexmp_fh implement the ->read_buf() and ->write_buf()
+	methods.  Leave the ->read() and ->write() implementations for
+	reference, even though they are not necessary.
+
+2010-11-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix check for read-only fs in mtab update
+
+	* Open /dev/null for write instead of read for redirecting stdout
+	and stderr
+
+	* If umount(8) supports --fake and --no-canonicalize (util-linux-ng
+	version 2.18 or later), and umount(2) supports the
+	UMOUNT_NOFOLLOW flag (linux kernel version 2.6.35 or later)  then,
+	"fusermount -u" will call the umount(2) system call and use
+	"umount --fake ..." to update /etc/mtab
+
+	* Added --disable-legacy-umount option to configure.  This
+	disables the runtime checking of umount(8) version.  When built
+	with this option then "fusermount -u" will fail if umount(8)
+	doesn't support the --fake and --no-canonicalize options.
+
+	* Fix fuse_buf_copy() if already at the end of the buffers
+
+	* Add new ->write_buf() method to low level interface.  This
+	allows passig a generic buffer, either containing a memory buffer
+	or a file descriptor.  This allows implementing zero copy writes.
+
+	* Add fuse_session_receive_buf() and fuse_session_process_buf()
+	which may be used in event loop implementations to replace
+	fuse_chan_recv() and fuse_session_process() respectively.
+
+	* Remove unnecessary restoring of current working directory in
+	"fusermount -u"
+
+	* Add ctx->pid to debug output
+
+	* Fix st_nlink value in high level lib if file is unlinked but
+	still open
+
+	* libfuse: add store request.  Request data to be stored in the
+	kernel buffers for a given inode.
+
+	* libfuse: add retrieve request.  Retrieve data stored in the
+	kernel buffers for a given inode.

+	uclibc + libiconv.  Patch by Natanael Copa
+
+2010-10-05  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add missing argument check in ulockmgr.c to prevent calling
+	ulockmgr_server with illegal arguments. This would cause an ever
+	growing list of ulockmgr_server processes with an endless list of
+	open files which finally exceeds the open file handle limit.
+	Patch by Markus Ammer
+
+2010-09-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix ambiguous symbol version for fuse_chan_new.
+	fuse_versionscript included fuse_chan_new in both FUSE_2.4 and
+	FUSE_2.6.  Remove the FUSE_2.4, which is invalid.
+
+2010-09-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix option escaping for fusermount.  If the "fsname=" option
+	contained a comma then the option parser in fusermount was
+	confused (Novell bugzilla #641480).  Fix by escaping commas when
+	passing them over to fusermount.  Reported by Jan Engelhardt
+
+2010-08-27  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add NetBSD support.  Patch from Emmanuel Dreyfus
+
+2010-07-12  Miklos Szeredi <miklos@szeredi.hu>
+
+	* libfuse: add buffer interface.  Add a generic buffer interface
+	for use with I/O.  Buffer vectors are supplied and each buffer in
+	the vector may be a memory pointer or a file descriptor.
+
+	* The fuse_reply_fd() interface is converted to using buffers.
+
+2010-06-23  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Make the number of max background requests and congestion
+	threshold tunable.  New options are "max_background" and
+	"congestion_threshold".  Only effective on linux kernel versions
+	2.6.32 or greater.  Patch by Csaba Henk
+
+2010-06-17  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add fuse_reply_fd() reply function to the low level interface.
+	On linux version 2.6.35 or greater this will use splice() to move
+	data directly from a file descriptor to the fuse device without
+	needing to go though a userspace buffer.  With the
+	FUSE_REPLY_FD_MOVE flag the kernel will attempt to move the data
+	directly into the filesystem's cache.  On earlier kernels it will
+	fall back to an intermediate buffer.  The options
+	"no_splice_write" and "no_splice_move" can be used to disable
+	splicing and moving respectively.
+ 
+2010-06-15  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix out-of-source build.  Patch by Jörg Faschingbauer
+
+	* Add a "nopath" option and flag, indicating that path argument
+	need not be calculated for the following operations: read, write,
+	flush, release, fsync, readdir, releasedir, fsyncdir, ftruncate,
+	fgetattr, lock, ioctl and poll.

+
+2010-01-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix compile error on FreeBSD.  Patch by Jay Sullivan
+
+2009-12-17  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Use '--no-canonicalize' option of mount(8) (available in
+	util-linux-ng version 2.17 or greater) to avoid calling
+	readling(2) on the newly mounted filesystem before the mount
+	procedure is finished.  This has caused a deadlock if "audit" was
+	enabled in the kernel.  Also use '--no-canonicalize' for umount to
+	avoid touching the mounted filesystem.
+
+2009-09-11  Miklos Szeredi <miklos@szeredi.hu>
+

+
+2009-07-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Clarify how the protocol version should be negotiated between
+	kernel and userspace.  Notably libfuse didn't correctly handle the
+	case when the supported major versions didn't match
+
+	* Add missing pthread link for libulockmgr.  Patch by  Petr Salinger
+
+2009-07-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* The context is extended with a 'umask' field.  The umask is sent
+	for mknod, mkdir and create requests by linux kernel version
+	2.6.31 or later, otherwise the umask is set to zero.  Also
+	introduce a new feature flag: FUSE_CAP_DONT_MASK.  If the kernel
+	supports this feature, then this flag will be set in conn->capable
+	in the ->init() method.  If the filesystem sets this flag in in
+	conn->want, then the create modes will not be masked.
+
+	* Add low level interfaces for lookup cache and attribute
+	invalidation.  This feature is available in linux kernels 2.6.31
+	or later.  Patch by John Muir
+
+	* Kernel interface version is now 7.12
+
+	* fusermount: Do not silently ignore command line arguments.
+	Patch by Sebastian Harl
+
+2009-06-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.8.0-pre3
+
+2009-06-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add fuse_getgroups (high level lib) and fuse_req_getgroups (low
+	level lib) functions to query the supplementary group IDs for the
+	current request.  Currently this is implemented on Linux by
+	reading from the /proc filesystem.
+
+2009-06-18  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add "noforget" option to high level lib to prevent ESTALE errors
+	on NFS exported filesystems.  This result in paths being cached
+	forever, resulting in ever growing memory usage.  Use with care.
+
+	* Add "no_remote_lock" option to disable remote file locking even
+	if the filesystem implements it.  With this option locking
+	primitives (flock, lockf, fcntl(F_SETLK)) will still work, but
+	will ignore remotely locked files.
+
+	* CUSE patches from Tejun Heo:
+
+	* Unrestricted ioctl support left some debris.  Clean them up:
+	  o No reason to pass around pointer to flags.  Pass flags directly.
+	  o Clean up comment and prototype parameter names.
+	  o fuse_lib_ioctl() didn't reply when get_path() failed.  Fix it.
+	  o Remove unused variables {in|out}_iov from fuse_lib_ioctl().
+
+	* Add fuse_reply_ioctl_iov()
+
+	* Move fuse_session, fuse_req and fuse_ll definitions to fuse_i.h
+	and make send_reply_iov() and fuse_setup_common() global (also in
+	fuse_i.h).  These will be used by CUSE support.
+
+	* Restructure fuse_ll_process()
+
+	* Implement libfuse side of CUSE support.  CUSE uses subset of FUSE
+	operations as dir operations don't make sense for CUSE where one
+	instance implements single character device.
+
+	CUSE support comes with its own cuse_lowevel_ops and related
+	initialization and helper functions.  Except for initialization, it
+	usage is basically identical to FUSE.
+
+	This patch also adds example/cusexmp.c which can create a character
+	device with name and device number specified on command line.  The
+	created device itself is pretty boring.  It's a bit bucket supporting
+	read, write and access via ioctl.
+
+2009-06-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add missing fuse_reply_bmap to versionscript.  Debian
+	Bug#531329.  Reported by Goswin Brederlow
+

+
+	* Only pass valid flags to ->setattr().
+
+2008-12-05  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Implement ioctl support.  On high level interface only
+	"restricted" ioctls are supported (which are defined with the
+	_IO(), _IOR(), _IOW() or _IOWR() macros).  Unrestricted ioctls
+	will only be allwed to CUSE (Character Device in Userspace)
+	servers.  Patch by Tejun Heo
+
+2008-11-28  Miklos Szeredi <miklos@szeredi.hu>

+2008-05-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Don't allow bigger than 4kB writes by default on 2.6.26 and
+	later kernels, so that filesystems not expecting this are not
+	broken on a kernel upgrade.  Provide a 'big_writes' mount option
+	to enable this feature.  In future API revisions this may become

+
+2008-02-03  Csaba Henk <csaba.henk@creo.hu>
+
+	* lib/mount_bsd.c:
+	- string formatting fixes
+	- exit if mounting has failed
+	  (in FreeBSD a mount failure is not critical per se, as the daemon
+	  still could be mounted externally, but waiting for such an event
+	  is more confusing than fruitful)
+	- ditch the kvm(8) stuff and simply use forced unmount which just
+	  won't block

+
+	* Remove erroneous 'fuse_opt_insert_arg@FUSE_2_5' from

+
+	* mount.fuse: add "setuid=USER" option which does a "su - USER"
+	for the filesystem
+
+	* fusermount: use "/bin/mount -f" to add entry to /etc/mtab, and
+	"/bin/umount" to remove entry from /etc/mtab.  This gets rid of
+	the ugly code dealing with mtab, as well as a possible race
+	between fusermount and mount trying to modify /etc/mtab at the

+2006-11-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix bug in certain error paths of lookup routines.  The request
+	object was reused for sending FORGET, which is illegal.  This bug
+	could cause an Oops in linux-2.6.18 or in fuse-2.6.0, and might
+	silently corrupt memory in earlier versions.  Report and test
+	program by Russ Cox
+
+2006-11-11  Miklos Szeredi <miklos@szeredi.hu>

+2006-10-13  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: Fix compilation on patched 2.6.18 (fc6) and 2.6.19.
+	Report from David Shaw
+
+	* lib: Fix lost error on renaming a file. Report from David Shaw
+
+	* lib: Fix lost error on hiding open files (renaming to
+	.fuse_hiddenXXXX)
+
+	* kernel: Fix a rare hang on SMP/32bit on heavy filesystem
+	activity.  The cause of the bug was that some calls to
+	i_size_write() were not protected by a lock, and hence
+	i_size_seqcount could become corrupted.  This caused subsequent
+	calls to i_size_read() to spin forever.  This is a long standing
+	bug was probably introduced in version 2.2, and thought to be
+	related to NFS exporting (it's not).  It was reported by various
+	people, but Dana Henriksen has finally helped me to track it down,
+	so big thanks to him
+
+	* kernel: Protect against truncation of a swapfile
+
+2006-10-10  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: Check for signature of super_operations->umount_begin().
+	Ubuntu kernel 2.6.17 seems to use the new signature found in
+	2.6.18.  Thanks to Florent Mertens for the report
+
+2006-10-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Make sure inode numers wrap around at 2^32.  This is needed on
+	dual 64bit/32bit architectures, because 32bit applications using
+	the non-largefile interface would otherwise break (EOVERFLOW error
+	would be returned by the stat() system call family)
+
+	* ulockmgr: handle the case, when a locking operation fails
+	because no more file desctriptors are available in
+	ulockmgr_server.  Also work around a Linux kernel bug (known to
+	exist for all Linux kernel versions <= 2.6.18) which may cause
+	sent file descriptors to be lost in the above case
+
+	* ulockmgr: optimize file descriptor use
+
+	* restore needed cpp flags to util/Makefile.am
+
+	* Install udev rules as 99-fuse.rules instead of 60-fuse.rules
+
+	* Minor clean up of udev rules
+
+	* Add a synchronous DESTROY message to kernel interface.  This is
+	invoked from umount, when the final instance of the filesystem is
+	released.  It is only sent for filesystems mounted with the
+	'blkdev' option for security reasons.
+
+	* If the DESTROY message is received, call the filesystem's
+	->destroy() method.  In this case it's not called from session
+	destruction as it would be otherwise.
+
+2006-10-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.6.0-rc2
+
+2006-10-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add support for FLUSH+RELEASE operation for FreeBSD.  Original
+	patch by Csaba Henk
+
+	* Add init script to insert fuse module and mount the control
+	filesystem.  The script is installed as /etc/init.d/fuse and on
+	debian based systems (where update-rc.d is available) symlinks
+	from /etc/rc*.d/ are also installed.
+
+	* Include '#define FUSE_USE_VERSION=XX' into examples so they
+	become more self contained.
+
+2006-09-30  Miklos Szeredi <miklos@szeredi.hu>
+
+	* API changes:
+
+	* Move lock_owner from a separate argument into fuse_file_info
+
+	* Add a flag to fuse_file_info indicating (1) a highlevel lock
+	operation (unlock all) was initiated by a flush, (2) a lowlevel
+	release operation should perform a flush as well.
+
+	* fusermount: revert modprobe change (2006-08-18) since it
+	doesn't work reliably with udev
+
+	* Add support for block device backed filesystems.  This mode is
+	selected with the 'blkdev' option, which is privileged.
+
+	* Add support for the bmap (FIBMAP ioctl) operation on block
+	device backed filesystems.  This allows swapon and lilo to work on
+	such filesystems.
+
+	* kernel changes:
+
+	* Drop support for kernels earlier than 2.6.9.  Kernel module from
+	previous (2.5.x) release can be used with library from this
+	release
+
+	* In fuse_dentry_revalidate() use dget_parent() instead of
+	dereferencing d_parent, since there's no protection against parent
+	changing and going away
+
+	* Protect nlookup from concurrent updates
+
+	* In lookup if a directory alias exists but is unused,
+	then get rid of it, otherwise return -EBUSY.
+
+	* In mkdir if a directory alias exists, return success, but leave
+	dentry negative.  In reality this could happen if a remote rename
+	immediately followed the mkdir.
+
+	* Don't BUG in fuse_iget() if multiple retries are needed to get a
+	good inode.  This could happen if several lookups are racing for
+	the same inode.
+
+2006-09-29  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix compilation on 2.6.9.  Report from Troy Ayers
+
+2006-09-27  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix Oops in fuse_readpages().  Reported by David Shaw
+
+2006-09-24  Csaba Henk <csaba.henk@creo.hu>
+
+	* Add support for nanosec times on FreeBSD
+
+	* Fix FreeBSD compatibility issues
+
+2006-09-23  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix one more compatibility bug.  Thanks to Ricardo Correia
+
+	* Fix utimens compilation with uClibc.  Patch from Jamie Guinan
+
+2006-09-22  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fixed several compatibility bugs in low level interface.
+	Reported by Ricardo Correia
+
+	* Add workaround for ARM caching bug
+
+2006-09-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Rename new utimes() method to more logical utimens()
+
+2006-09-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fuse tried to unlink already unlinked hidden files.  Bug
+	reported by Milan Svoboda
+
+2006-09-10  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.6.0-rc1
+
+2006-09-10  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: Fix unlock on close for kernels < 2.6.18
+
+	* Add ulockmgr library & server.  This can be used for handling
+	file locking requests either directly from libfuse or over a
+	network, etc.  This first version is not optimized and the number
+	of file descriptors it uses may get out of hand
+
+2006-09-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: Add interrupt support to high level library, which may be
+	enabled with the 'intr' mount option.
+
+	* When an operation is interrupted the thread handling that
+	operation will receive SIGUSR1 (or other signal specified with the
+	'intr_signal=N' option).  The library installs a no-op signal
+	handler for this signal, unless there's already a handler
+	installed.
+
+	* The filesystem may query interrupt status (regardless of 'intr')
+	with the fuse_interrupted() function.
+
+	* mount.fuse: initialize $HOME if not set.  Report from Sven Goldt
+
+2006-09-03  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: Multithreaded loop now allows unlimited number of threads.
+	This is needed for locking operations which may block
+	indefinitely.  Also the kernel now doesn't limit the number of
+	outstanding requests so the library shouldn't do so either.
+
+2006-09-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix recursive lock bug in interrupt handling
+
+	* Add utimes() method to highlevel interface, which supports
+	setting times with nanosecond resolution
+
+2006-08-18  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: fix page leak if fuse_readpages() failed in it's
+	initialization.  Bug found and original patch from Alexander
+	Zarochentsev
+
+	* For linux kernels >=2.6.18 (2.6.19 if using the fuse module from
+	the kernel tree) the statfs method will receive the path within
+	the filesystem on which the stat(v)fs syscall was called
+
+	* fusermount: try to modprobe fuse module if invoked by root and
+	unable to open device.  This is needed with udev, since the device
+	node will be created only when the module is inserted, hence
+	module autoloading won't work.  Reported by Szakacsits Szabolcs
+
+2006-07-30  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fusermount: if selinux is active, restore the original file's
+	security context in unmount_rename().  Redhat bugzilla id 188561.
+	Patch from Yves Perrenoud
+
+	* Add POSIX file locking operation to high level library
+
+	* Initialize context for unlink of hidden files on umount.  Bug
+	reported by Tim Stoakes
+
+2006-07-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Multiple release() calls can race with each other, resulting in
+	the hidden file being deleted before the last release finishes.
+	Bug found and patch tested by Mark Huijgen
+
+2006-07-05  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fusermount: if /dev/fuse doesn't exist, suggest modprobing fuse;
+	this makes sense on systems using udev.  Reported by Szakacsits
+	Szabolcs
+
+2006-06-29  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.6.0-pre3
+
+2006-06-29  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Support in kernel module for file locking and interruption.  The
+	same functionality is available in official kernels >= 2.6.18
+
+2006-06-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add POSIX file locking support
+
+	* Add request interruption
+
+2006-06-06  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add missing pthread_rwlock_destroy().  Patch from Remy Blank
+
+2006-06-05  Remy Blank <remy.blank@pobox.com>
+
+	* lib: canonicalize mount point in fuse_helper_opt_proc() so that
+	unmounting succeeds even if mount point was relative.
+
+2006-06-04  Csaba Henk <csaba.henk@creo.hu>
+
+	* lib: fix emergency umount in helper.c when malloc fails.
+	(The way it was done would end up in a segfault.)
+
+2006-06-01  Csaba Henk <csaba.henk@creo.hu>
+
+	* lib: adjust threading related compiler flags.
+	Switch to "-pthread" from "-lpthread" as that's the preferred
+	one on several platforms. Consulted with Terrence Cole and
+	Miklos Szeredi
+
+2006-05-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: search fusermount in installation directory (bindir) as
+	well as in PATH.
+
+2006-05-03  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: fix compilation if CLOCK_MONOTONIC is not defined.
+	Reported by Christian Magnusson
+
+2006-04-23  Csaba Henk <csaba.henk@creo.hu>
+
+	* lib: make FreeBSD mount routine recognize if kernel features
+        backgrounded init and if it does, run the mount util in foreground
+        (similarly to Linux)
+
+2006-04-21  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: fix fput deadlock fix, the lockless solution could lead
+	to "VFS: busy inodes after umount..."
+
+	* kernel: fix race between checking and setting file->private_data
+	for the device.  Found by Al Viro
+
+2006-04-11  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: remove request pool, instead allocate requests on
+	demand.  Account the number of background requests, and if they go
+	over a limit, block the allocation of new requests.
+
+	* kernel: fix deadlock if backgrounded request holds the last
+	reference to the super block
+
+	* kernel: don't use fuse_reset_request() during direct I/O
+
+2006-04-06  Csaba Henk <csaba.henk@creo.hu>
+
+	* lib: Let FreeBSD mount option parsing routine recognize "no"
+	prefixes for FUSE specific options as well
+
+2006-04-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: Add missing rwlock initialization.  Patch by Ryan Bradetich
+
+2006-03-17  Miklos Szeredi <miklos@szeredi.hu>
+
+	* API changes:
+
+	* fuse_main(), fuse_setup() and fuse_new() have an additionl
+	user_data parameter
+
+	* fuse_mount() returns a 'struct fuse_chan' pointer instead of a
+	file descriptor
+
+	* fuse_unmount() receives a 'struct fuse_chan' pointer.  It
+	destroys the given channel
+
+	* fuse_teardown() no longer has a file descriptor parameter
+
+	* new exported functions: fuse_session_remove_chan(),
+	fuse_get_session(), fuse_daemonize()
+
+	* fuse_chan_recv() may now return a new channel which will be used
+	to send the reply
+
+2006-03-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.6.0-pre2
+
+2006-03-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Don't unmount if already unmounted.  This fixes a problem seen
+	in the following situation: Lazy unmount a busy filesystem; Mount
+	a new one in top; When the first finally unmounts, the second also
+	unmounts.  Reported by Franco Broi
+
+2006-03-15  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lowlevel lib: use indirect function calls instead of a
+	switch/case construct.  Besides increased efficiency it helps
+	maintainability & readability too.  Patch from Florin Malita
+
+2006-03-13  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: replace global spinlock with a per-connection spinlock
+
+2006-03-10  Miklos Szeredi <miklos@szeredi.hu>

+	from Yura Pakhuchiy
+

+
+	* Fix O_ASYNC handling in fuse_dev_release().  From Jeff Dike
+
+2006-03-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add O_ASYNC and O_NONBLOCK support to FUSE device.  Patch by
+	Jeff Dike
+
+	* Renamed fuse_chan_receive() to fuse_chan_recv() and changed
+	interface to return -errno in case of error.
+
+2006-03-01  Csaba Henk <csaba.henk@creo.hu>
+
+	* libfuse: pass device file descriptor to fuse_unmount(), rewrite
+	FreeBSD implementation so that it uses libc (sysctl backed) instead
+	of an embdedded script (kmem backed). Adjust the control flow of
+	hello_ll so that device doesn't get closed before unmount attempt.
+
+2006-02-25  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Lowlevel lib: return all-zero statvfs data if filesystem doesn't
+	implement method.  This is needed on FreeBSD, and nicer on Linux
+	too.  Highlevel lib already did this.  Reported by Csaba Henk
+
+	* Fix negative entry handling.  There was a bug, that negative
+	lookups with timeouts (nodeid == 0) returned -EIO.
+
+2006-02-23  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix race between RELEASE and UNLINK, which might leave
+	.fuse_hidden* files around
+
+2006-02-21  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fusexmp_fh: implement flush() method and call close() on the
+	open file descriptor.  This is needed if used on an NFS
+	filesystem, which buffers data until file is closed.  Franco Broi
+	spotted the situation when 'cp -p' failed to set the modification
+	time because of this.
+
+2006-02-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.6.0-pre1

+2006-02-17  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Lowlevel lib: Unify fuse_dirent_size() and fuse_add_dirent()
+	into a single function fuse_add_direntry().  This cleans up the
+	interface and makes it possible to do stacking.
+
+2006-02-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix rare race betweeen abort and release caused by failed iget()
+	in fuse_create_open().
+
+	* Add 'ac_attr_timeout' option e.g. for filesystems which do their
+	own attribute caching.
+
+2006-02-15  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Work around FreeBSD runtime linker "feature" which binds an old
+	version of a symbol to internal references if the symbol has more
+	than one version.  This resulted in infinite recursion in
+	fuse_lowlevel_new_compat25().
+
+2006-02-10  Csaba Henk <csaba.henk@creo.hu>
+
+	* Refine clock_gettime() querying so that linker options
+	shall be set as it's appropriate for the target platform.
+
+2006-02-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix udev rule syntax.  Reported by Nix
+
+2006-02-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* In some cases udev rule seems to be ineffective when installed
+	as 40-fuse.rules but work as 60-fuse.rules.  Reported by John Hunt
+
+2006-02-03  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix compilation when build directory is different from source
+	directory.  Reported by Frédéric L. W. Meunier
+
+2006-02-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix even bigger bug introduced in fix for request_end() on
+	2006-01-14.  Reported by Gal Rosen
+
+2006-01-30  Miklos Szeredi <miklos@szeredi.hu>
+
+	* highlevel-lib: add 'auto_cache' option.  This caches file data
+	based on modification time and size
+
+2006-01-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Sanitize storage type and help message in mount_bsd.c.  Patch
+	from Csaba Henk
+
+	* fuse_opt: add new helper constants FUSE_OPT_KEY_KEEP and
+	FUSE_OPT_KEY_DISCARD
+
+	* Add options 'max_readahead', 'sync_read' and 'async_read'
+
+	* Kernel ABI version 7.6:
+
+	* Negotiate the 'max_readahead' value and 'async_read' flags with
+	userspace in the INIT method
+
+	* Add connection info to ->init() methods to both lowlevel and
+	highlevel API
+
+	* Fall back to synchronous read() behavior if either library or
+	userspace filesystem is using the old interface version.  This is
+	needed so non-updated filesystems won't be confused by the
+	different read() behavior
+
+2006-01-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: if "fsname=" option was given, pass it to fusermount
+
+	* fuse_opt: add new fuse_opt_insert_arg() function, which is
+	needed by filesystems to implement some argument manipulations
+	correctly
+
+	* fuse_opt: fix memory leak in handling "--" option
+
+2006-01-18  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: fix detection of case when fuse is not configured into
+	the kernel either as module or built-in
+
+	* fuse_opt.h: fix incompatibility with C++ compilers by renaming
+	'template' structure member to 'templ'.  Reported by Takashi Iwai
+
+	* fuse.h: fix compatibility bugs.  Patch by Yura Pakhuchiy
+
+	* kernel: support version 2.6.16 (i_sem -> i_mutex)
+
+2006-01-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added (again) asynchronous readpages support
+
+	* Each connection now shows up under /sys/fs/fuse/connections
+
+	* Connection attributes exported to sysfs: 'waiting' number of
+	waiting requests; 'abort' abort the connection
+
+	* Connection may be aborted through either the sysfs interface or
+	with 'umount -f mountpoint'
+
+2006-01-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.5.0
+
+2006-01-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: fix a couple of bugs
+
+	* Order of request_end() and fuse_copy_finish() was wrong.
+	Posthumous note: Franco Broi managed to exploit this, though it
+	seemed quite impossible
+
+	* request_end() used request pointer after decrementing refcount
+
+	* Clearing ->connected or ->mounted connection flags could race
+	with setting other bitfields not protected with a lock
+
+2006-01-10  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: add necessary compile flags for 2.4.X/x86_64.
+	Report from Sean Ziegeler
+
+2006-01-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.5.0-pre2
+
+2006-01-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Applied patch from Csaba Henk, to update mount_bsd to new
+	fuse_mount() semantics
+
+	* Ignore auto,noauto,... options in mount.fuse.  Reported by Frank
+	Steiner and Don Taber
+
+	* fusermount: add 'dirsync' mount option
+
+2006-01-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Improved help reporting and added version reporting to library
+
+2006-01-06  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Change working directory to "/" even if running in the
+	foreground.  Patch from Jonathan Brandmeyer
+
+	* Changed lots of functions to use 'struct fuse_args' instead of
+	separate argc and argv
+
+	* Added fuse_parse_cmdline(), fuse_set_signal_handlers() and
+	fuse_remove_signal_handlers() functions, so that it's now pretty
+	easy to get all the functionality of fuse_main() with a filesystem
+	using the lowlevel API.
+
+2006-01-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* mount.fuse: the 'user' option should be ignored. Report and
+	solution from Mattd.
+
+	* mount.fuse: export PATH in the right place. Report and patch
+	from Hannes Schweizer
+
+2005-12-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Clean up the option parsing interface slightly, by creating an
+	"argument list" structure, that contains the argument vector and
+	count
+
+2005-12-15  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fusermount: check if /mnt/mtab is a symlink and don't modify it
+	in that case
+
+	* kernel: simplify request size limiting. INIT only contains
+	maximum write size, maximum path component size remains fixed at
+	1024 bytes, and maximum xattr size depends on read buffer.
+
+2005-12-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix readdir() failure on x86_64, of 32bit programs compiled
+	without largefile support.  Bug report and help from Anthony
+	Kolasny
+
+	* If lookup returns invalid mode, return -EIO instead of creating
+	a regular file
+
+	* Add current output argument vector to option processing
+	function
+
+2005-12-12  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix stale code in ifdef FreeBSD.  Patch from Csaba Henk
+
+2005-12-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.5.0-pre1
+
+2005-12-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* libfuse: added option parsing interface, defined in
+	<fuse_opt.h>.
+
+2005-12-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Return EIO for file operations (read, write, fsync, flush) on
+	open files whose inode has become "bad".  Inodes will be marked
+	"bad" if their type changes.  Bug report by Csaba Henk
+
+2005-12-06  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Use bigger request buffer size.  write() did not work on archs
+	with > 4k page size, Bug report by Mark Haney
+
+	* ABI version 7.5:
+
+	* Extend INIT reply with data size limits
+
+2005-12-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix memory leak in fuse_read_cmd()/fuse_process_cmd().  Bug
+	reported by Vincenzo Ciancia
+
+	* Handle exit-by-umount in fuse_read_cmd()
+
+2005-11-29  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Check if '-msoft-float' option is supported by compiler when
+	configuring for a 2.4.x kernel.  Bug report by Mark Haney
+
+	* In multithreaded loop send a TERM signal to the main thread if
+	one of the other threads exit.  Needed on FreeBSD for a clean exit
+	on umount.  Should not cause any harm on Linux either
+
+2005-11-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix bug in 32-bit file handle compatibility
+
+2005-11-27  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Block TERM, INT, HUP and QUIT signals in all but the main
+	thread.  According to POSIX it's not specified which thread will
+	receive these signals.
+
+	* Kernel changes:
+
+	* Check for directory aliasing on mkdir, not just on lookup
+
+	* Check for special node ID values in create+open operation
+
+	* Sync with -mm: readv, writev, aio_read and aio_write methods
+	added to file operations
+
+	* Cleanups: lookup code, page offset calculation
+
+	* ABI stepped to 7.4, changes:
+
+	* frsize member added to fuse_kstatfs structure
+
+	* added support for negative entry caching: on lowlevel API if
+	fuse_entry_param::ino is set to zero in reply to a lookup request,
+	the kernel will cache the dentry for the specified amount of time.
+
+	* libfuse: added 'negative_timeout' option: specifies how much
+	negative entries should be cached.  Default is zero, to be
+	compatible with prior versions
+
+2005-11-22  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add detection of mainline FUSE code in running kernel
+
+2005-11-21  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Don't use async cancelation in multithreaded loop.  This makes
+	it more portable to systems where read() is not async cancel safe.
+	Report from Andriy Gapon
+
+2005-11-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Warn if API version 11 compatibility is requested
+
+2005-11-17  Miklos Szeredi <miklos@szeredi.hu>
+
+	* More FreeBSD merge
+
+	* fusermount: don't allow mountpoints with '\n', '\t', or '\\' in
+	them, because it corrupts /etc/mtab.  Found by Thomas Biege
+	CVE-2005-3531
+
+	* libfuse: don't use system() to invoke 'fusermount -u ...'
+	because it breaks mountpoints with spaces in them into multiple
+	arguments
+
+2005-11-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Merge library part of FreeBSD port.  Patch by Csaba Henk
+
+2005-11-11  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Use 64bit type for file handle, so the full range supported by
+	the kernel interface is available to applications
+
+2005-11-10  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Moved mountpoint argument checking from fuse_parse_cmdline() to
+	fuse_mount() in preparation to FreeBSD merge.
+
+2005-11-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Remove unneeded close() from fuse_teardown().  Spotted by Csaba
+	Henk.
+
+2005-11-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Make the statfs change backwards compatible.
+
+2005-11-06  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Change ->statfs() method to use 'struct statvfs' instead of
+	'struct statfs'.  This makes the API more portable since statvfs()
+	is defined by POSIX.
+
+2005-10-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add fgetattr() method, which currently will only be called after
+	a successful call to a create() method.
+
+2005-10-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Change kernel ABI version to 7.3
+
+	* Add ACCESS operation.  This is called from the access() system
+	call if 'default_permissions' mount option is not given, and is
+	not called on kernels 2.4.*
+
+	* Add atomic CREATE+OPEN operation.  This will only work with
+	2.6.15 (presumably) or later Linux kernels.
+
+	* Add ftruncate() method.  This will only work with 2.6.15
+	(presumably) or later Linux kernels.
+
+	* Fix kernel module compile if kernel source and build directories
+	differ.  Report and initial patch by John Eastman
+
+2005-10-18  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: optimize buffer reallocation in fill_dir.
+
+2005-10-17  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.4.1
+
+2005-10-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* libfuse: add debug for write result (by Shaun Jackman) and
+	warnings for too large read/write result
+
+2005-10-11  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Spelling fixes, thanks to Ioannis Barkas
+
+2005-10-10  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fuse_common.h: use extern "C".  Thanks to Valient Gough for the
+	patch
+
+2005-10-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* highlevel-lib: init() and destroy() methods didn't have an
+	initialized fuse_context.  Bug reported by Tim Stoakes
+
+2005-10-04  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.4.0
+
+2005-10-03  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add documentation to fuse_lowlevel.h
+
+	* API cleanups:
+
+	* Remove definitions of unused FATTR_CTIME / FUSE_SET_ATTR_CTIME
+
+	* Move fuse_mount() and fuse_unmount() to fuse_common.h
+
+	* Change the return type of fuse_reply_none() from int to void.
+
+2005-09-30  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: NFS exporting leaked dentries.  Bug found and fixed by
+	Akshat Aranya.
+
+2005-09-29  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fusermount: fix error message, when unable to open /dev/fuse.
+	Report by Balázs Pozsár
+
+2005-09-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* UClibc fixes from Christian Magnusson
+
+2005-09-27  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added NAME="%k" to util/udev.rules.  Fix by Mattias Wadman.
+
+2005-09-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.4.0-rc1
+
+2005-09-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fusermount: allow user umount in the case when /etc/mtab is a
+	symlink to /proc/mounts.  Reported by Balázs Pozsár.
+
+2005-09-23  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Check for special node ID values in lookup and creation
+
+2005-09-22  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Slight optimization in returning EINVAL error in case of an open
+	with O_DIRECT flag.
+
+2005-09-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Remove '--enable-auto-modprobe' configure flag.  Module
+	auto-loading is now handled by the kernel.
+
+2005-09-15  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Install UDEV rule file, so /dev/fuse is created with mode 0666.
+	Help from Jens M. Noedler.
+
+2005-09-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add memory cleanup on thread exit
+
+2005-09-13  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Set umask to zero in fusexmp and fusexmp_fh, so that
+	files/directories are created with the requested mode.
+
+2005-09-12  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Don't ignore read error in multithreaded loop
+
+2005-09-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.4.0-pre2
+
+2005-09-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Revert lock and access operations.  Postpone these until 2.5.
+
+2005-09-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix compile warning on 2.6.13 and later
+
+	* Fix compilation on old kernels
+
+2005-08-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: always refresh directory contents after rewinddir() to
+	conform to SUS.  Bug found by John Muir.
+
+2005-08-15  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.4.0-pre1
+
+2005-08-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: cleaned up (or messed up, depending on your POV) the low
+	level library API.  Hopefully this is close to the final form.
+
+2005-08-05  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fusermount: don't allow empty mountpoint argument, which defeats
+	automatic umounting in fuse_main().  Bugreport by Václav Jůza
+
+2005-08-03  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fix warnings in fuse.h and fuse_lowlevel.h if -Wshadow compiler
+	option is used (Paul Alfille).
+
+2005-08-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* highlevel-lib: added mount options "attr_timeout" and
+	"entry_timeout".  These options control the length of time file
+	attributes and entries (names) are cached.  Both default to 1.0
+	second.
+
+	* kernel: correctly handle zero timeout for attributes and entries
+
+2005-08-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added missing symbols to versionscript (Joshua J. Berry)
+
+	* kernel: implement two flags, open can set: 'direct_io' and
+	'keep_cache'.  These correspond exactly to mount options
+	'direct_io' and 'kernel_cache', but allow a per-open setting.
+
+	* Move 'direct_io' and 'kernel_cache' mount option handling to
+	userspace.  For both mount options, if the option is given, then
+	the respective open flag is set, otherwise the open flag is left
+	unmodified (so the filesystem can set it).
+
+	* lib (highlevel): make open method optional
+
+2005-07-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: invalidate attributes for read/readdir/readlink
+	operations
+
+	* kernel: detect newer UML kernels
+
+2005-07-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Make the installation path of fuse.ko and mount.fuse
+	configurable through INSTALL_MOD_PATH and MOUNT_FUSE_PATH
+	environment variables.  Requirement and help from Csaba Henk.
+
+2005-07-22  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix bug, that causes filesystem requests to hang when unique
+	request counter becomes negative.  This happens after
+	2,147,483,648 operations, so most people won't care.  Thanks to
+	Franco Broi for the report and testing.
+
+2005-07-21  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Don't change mtime/ctime/atime to local time on read/write.
+	Bug reported by Ben Grimm
+
+	* Install fuse_common.h and fuse_lowlevel.h.  Report by Christian
+	Magnusson
+
+	* fusermount: use getopt_long() for option parsing.  It allows the
+	use of '--' to stop argument scanning, so fusermount can now
+	operate on directories whose names begin with a '-'.  Patch by
+	Adam Connell
+
+2005-07-15  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fusermount: add '-v', '--version' and '--help' options
+
+	* add inode based API
+
+2005-07-12  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: don't block signals in worker threads.  Problem noticed by
+	Usarin Heininga
+
+2005-07-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: don't allow both 'allow_other' and 'allow_root' options to
+	be given
+
+2005-07-06  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fusermount: check if mountpoint is empty (only '.' and '..' for
+	directories, and size = 0 for regular files).  If "nonempty"
+	option is given, omit this check.  This is useful, so users don't
+	accidentally hide data (e.g. from backup programs).  Thanks to
+	Frank van Maarseveen for pointing this out.
+
+	* kernel: check if mandatory mount options ('fd', 'rootmode',
+	'user_id', 'group_id') are all given
+
+	* lib: simplify 'readdir_ino' handling
+
+	* lib: add mount options 'umask=M', 'uid=N', 'gid=N'
+
+2005-07-03  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: clean up 'direct_io' code
+
+2005-06-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add 'mount.fuse' written by Petr Klima
+
+	* '/dev/fuse' is created by 'make install' if does not yet exist
+
+2005-06-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix UCLIBC compile error.  Patch by Christian Magnusson
+
+2005-06-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Enable the auto-loading of the module via access to the
+	corresponding device file.  Patch by Takashi Iwai.
+
+	* Allow mounting a regular file (over a regular file) for
+	unprivleged users.
+
+	* Do not create temporary device file.  Require "/dev/fuse" to
+	exist, and be readable/writable by the mounting user.
+
+2005-06-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.3.0
+
+2005-06-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix serious information leak: if the filesystem returns a short
+	byte count to a read request, and there are non-zero number of
+	pages which are not filled at all, these pages will not be zeroed.
+	Hence the user can read out previous memory contents.  Found by
+	Sven Tantau.
+
+2005-05-27  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add "readdir_ino" mount option, which tries to fill in the d_ino
+	field in struct dirent.  This mount option is ignored if "use_ino"
+	is used.  It helps some programs (e.g. 'pwd' used over NFS from a
+	non-Linux OS).  Patch by David Shaw.
+
+2005-05-12  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.3-rc1
+
+2005-05-12  Miklos Szeredi <miklos@szeredi.hu>
+
+	* File save in krusader and other editors doesn't work with sshfs,
+	because open() is interrupted by a periodic signal, and open()
+	restarts forever, without any progress.  This could just be fixed
+	in open(), but the problem is more generic: if signals are
+	received more often than the filesystem can get the request to
+	userspace, it will never finish.  This is probably only a
+	theoretical problem, nevertheless I'm removing the possibility to
+	interrupt requests with anything other than SIGKILL, even before
+	being sent to userspace.  Bugreport by Eduard Czimbalmos.
+
+2005-05-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* libfuse: add "tree_lock" rwlock, that is locked for write in
+	rename, unlink and rmdir, and locked for read in all other
+	operations.  This should fix the rename/release race reported by
+	Valient Gough and others.  The solution is very coarse, a finer
+	grained locking scheme could be implemented, but it would be much
+	more complex.  Let's see whether this is good enough.

+2005-05-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.3-pre7
+
+2005-05-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Better fix for out of order FORGET messages.  Now the
+	LOOKUP/FORGET messages are balanced exactly (one FORGET can
+	balance many lookups), so the order no longer matters.  This
+	changes the kernel ABI slightly, but the library remains backward
+	compatible.
+
+2005-05-06  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix abort for out of order FORGET messages.  Again.  Spotted by
+	Franco Broi again.  Sorry :)
+
+2005-04-29  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.3-pre6
+
+2005-04-29  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Make fusermount work with fuse kernel modules not yet supporting
+	the "group_id" option (added for the purpose of stricter
+	permission checking).
+
+2005-04-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Check for hard-linked directories in lookup.  This could cause
+	problems in the VFS, which assumes that such objects never exist.
+
+	* Make checking of permission for other users more strict.  Now
+	the same privilege is required for the mount owner as for ptrace
+	on the process performing the filesystem operation.
+
+2005-04-23  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.3-pre5
+
+2005-04-22  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add -msoft-float to kernel module compile flags for 2.4.X.  This
+	is needed on certain architectures.  Report from Chris Kirby
+
+	* Fix buggy behavior of open(..., O_CREAT|O_EXCL) if interrupted.
+	Reported by David Shaw
+
+	* Remove "allow_root" option from kernel module, and implement
+	it's functionality in the library
+
+	* Fix Oops caused by premature release of fuse_conn.  Clean up
+	related code, to be more readable
+
+	* Sendfile should not use page cache if "direct_io" mount option
+	is given
+
+2005-04-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix Oops in case of nfs export.  Spotted by David Shaw
+
+	* Fix another Oops in case of write over nfs with direct_io turned
+	on.  Again spotted by David Shaw
+
+2005-04-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.3-pre4
+
+2005-04-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* lib: finalized new readdir() interface, which now supersedes the
+	getdir() method.
+
+2005-04-03  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.3-pre3
+
+2005-04-03  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Implement backward compatibility with version 5 kernel ABI
+
+2005-04-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.3-pre2
+
+2005-04-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: fix dirent offset handling
+
+	* lib: add readdir and releasedir methods
+
+	* lib: use fh field of fuse_file_info in opendir, readdir,
+	releasedir and fsyncdir methods
+
+	* lib: check kernel API version and bail out of it's old.  This
+	will be properly fixed in the next release
+
+2005-03-31  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.3-pre1
+
+2005-03-31  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel API: add padding to structures, so 64bit and 32bit
+	compiler will return the same size
+
+	* kernel API: add offset field to fuse_dirent.  This will allow
+	more sophisticated readdir interface for userspace
+
+	* kernel API: change major number to 6
+
+	* kernel: fix warnings on 64bit archs
+
+	* kernel: in case of API version mismatch, return ECONNREFUSED
+
+2005-03-24  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: trivial cleanups
+
+2005-03-21  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add fsyncdir() operation
+
+2005-03-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: add locking to background list (fixes previous fix)
+
+2005-03-18  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: fix bug which could cause leave busy inodes after
+	unmount, and Oops.
+
+2005-03-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* examples: add -lpthread to link flags to work around valgrind
+	quirk
+
+	* lib: don't exit threads, so cancelation doesn't cause segfault
+
+2005-03-04  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: fix nasty bug which could cause an Oops under certain
+	situations.  Found by Magnus Johansson
+
+2005-02-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* libfuse: added opendir() method.  This can be used in case
+	permission checking in getdir() is too late.  Thanks to Usarin
+	Heininga for pointing out this deficiency
+
+	* libfuse: added init() and destroy() methods to fuse_operations
+
+	* kernel: llseek() method for files and directories made explicit
+
+	* kernel: fixed inode leak in NFS export in case of nodeid
+	wrapping
+
+2005-02-15  Miklos Szeredi <miklos@szeredi.hu>
+
+	* libfuse: clean up some unitialized memory found with valgrind
+
+	* Add -lpthread to Libs in fuse.pc.  Valgrind seems to need an
+	explicitly linked libpthread for applications
+
+2005-02-10  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fusermount: set umask, otherwise /etc/mtab will have
+	unpredictable permission.  Spotted by Jindrich Kolorenc
+
+	* fusermount: set owner and group of /etc/mtab to original values
+	on unmount
+
+	* libfuse: add 'use_ino' option to help.  Patch by Valient Gough
+
+2005-02-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Cleaned up directory reading (temporary file is not used)
+
+2005-02-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.2
+
+2005-02-02  Miklos Szeredi <miklos@szeredi.hu>

+
+2005-01-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix compilation on 2.6.7
+
+2005-01-26  Miklos Szeredi <miklos@szeredi.hu>
+

+
+2005-01-26  Miklos Szeredi <miklos@szeredi.hu>
+

+	passed as the first argument.  Found by Anton Altaparmakov
+
+2005-01-21  Miklos Szeredi <miklos@szeredi.hu>
+
+	* LIB: fix double reply in readdir operation
+
+	* fusermount: fix uid checking bug.  Patch by Adam Connell
+
+	* KERNEL: fix compile on various RedHat patched 2.4 kernels.
+	Patch by Keshava Gowda
+
+2005-01-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* KERNEL: provide correct llseek semantics for fuse device (fixes
+	a bug on Progeny 2.4.20 kernel).  Reported by Valient Gough
+
+2005-01-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.2-pre5 (matches kernel 2.6.11-rc1-mm2)
+
+2005-01-18  Miklos Szeredi <miklos@szeredi.hu>
+
+	* KERNEL ABI: remove GETDIR operation, and add OPENDIR, READDIR
+	and RELEASEDIR.  This ends the ugly hack of passing a file
+	descriptor to the kernel, and actually makes the code simpler.
+
+2005-01-17  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.2-pre4
+
+2005-01-17  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fusermount: remove capability setting, which was the cause of
+	problems for some users.  It seems that FS related capabilities
+	are removed by setfsuid(), so this isn't even needed.
+
+2005-01-15  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fix compilation on 2.4 kernels (reported by Valient Gough)
+
+	* fix failure to unmount bug (found by David Shaw)
+
+	* fusermount: improve parsing of /etc/fuse.conf
+
+2005-01-13  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Remove 'mount_max' and 'user_allow_other' module options.  These
+	are now checked by fusermount, and can be set in /etc/fuse.conf
+
+	* KERNEL: change check for fsid == 0 to capable(CAP_DAC_OVERRIDE)
+
+2005-01-11  Miklos Szeredi <miklos@szeredi.hu>
+
+	* KERNEL: fix possible inode allocation problem, where
+	sizeof(struct inode) is not aligned (found by Mike Waychison)
+
+	* KERNEL: use new follow_link/put_link methods
+
+	* KERNEL: cosmetic fixes
+
+2005-01-10  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.2-pre3
+
+2005-01-10  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add missing code that was accidently left out
+
+2005-01-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.2-pre2
+
+2005-01-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Change "uid" mount option to "user_id" to avoid confusion with a
+	mount option "uid" commonly used by many filesystems
+
+2005-01-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.2-pre1
+
+2005-01-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* If FUSE is configured in the kernel, don't build it by default
+
+2005-01-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Compile fix by Christian Magnusson
+
+2005-01-05  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix compilation for 2.6.{0-5} kernels
+
+2005-01-04  Miklos Szeredi <miklos@szeredi.hu>
+
+	* KERNEL: if request is interrupted, still keep reference to used
+	inode(s) and file, so that FORGET and RELEASE are not sent until
+	userspace finishes the request.
+
+	* remove /{sys,proc}/fs/fuse/version, and instead add an INIT
+	request with the same information, which is more flexible,
+	simpler, works on embedded systems.
+
+2004-12-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* KERNEL ABI: update interface to make it independent of type
+	sizes.  This will help on 64 bit architectures which can run
+	legacy 32 bit applications.
+
+	* KERNEL ABI: add "len" field to request headers.  This will allow
+	sending/receiving requests in multiple chunks.
+
+	* KERNEL: handle file type change more intelligently
+
+	* LIB: "-o debug" option should disable backgrounding (fix by
+	Fabien Reygrobellet)
+
+2004-12-13  Miklos Szeredi <miklos@szeredi.hu>
+
+	* KERNEL: invalidate dentry/attributes if interrupted request
+	could leave filesystem in an unknown state.
+
+2004-12-12  Miklos Szeredi <miklos@szeredi.hu>
+
+	* KERNEL: lots of cleanups related to avoiding possible deadlocks.
+	These will cause some regressions, but stability is considered
+	more important.  If any of these features turns out to be
+	important, it can be readded with the deadlock problems addressed.
+
+	* Make all requests interruptible (only with SIGKILL currently).
+	This can be used to break any deadlock produced by the userspace
+	filesystem accessing it's own exported files.  The RELEASE request
+	is special, because if it's interrupted before sending it to
+	userspace it is still sent, but the reply is not awaited.
+
+	* If request is interrupted before being sent to userspace, and if
+	it hasn't yet got any side effects, it is always restarted,
+	regardless of the SA_RESTART flag.  This makes these interruptions
+	transparent to the process.
+
+	* Remove shared-writable mmap support, which was prone to an
+	out-of-memory deadlock situation
+
+	* Remove INVALIDATE userspace initiated request
+
+	* Make readpages() synchronous.  Asynchronous requests are
+	deadlock prone, since they cannot be interrupted.
+
+	* Add readv/writev support to fuse device operations
+
+	* Remove some printks, which userspace FS can use for a DoS
+	against syslog
+
+	* Remove 'large_read' mount option from 2.6 in kernel, check it in
+	fusermount instead
+
+	* LIB: improve compatibility with a fuse.h header installed in
+	${prefix}/include which in turn includes the real header.
+
+	* LIB: improve compatibility by defining fuse_main() (which is now
+	not used), so old configure scripts find it.
+
+2004-12-10  Miklos Szeredi <miklos@szeredi.hu>
+
+	* When mounting on a subdirectory of / don't duplicate slashes at
+	the beggining of path (spotted by David Shaw)
+
+2004-12-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix bug causing garbage in mount options (spotted by David Shaw)
+
+2004-12-07  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add 'writepage' flag to 'fuse_file_info'.
+
+	* More comments in fuse.h
+
+	* Get rid of double underscores
+
+2004-12-04  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add -D_FILE_OFFSET_BITS=64 to cflags provided by pkg-config
+
+	* helper.c: add -ho option, which only displays the options not
+	the usage header.  This can be used by filesystems which have
+	their own options.
+
+2004-12-03  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add source compatibility to 2.1 and 1.1 APIs.  To select betwen
+	versions simply define FUSE_USE_VERSION to 22, 21 or 11 before
+	including the fuse header
+
+	* Add binary compatibility to 2.1 version of library with symbol
+	versioning
+
+2004-12-03  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.1
+
+2004-12-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: clean up writing functions
+
+	* kernel: no allocation on write in direct_io mode
+
+	* move linux/fuse.h to fuse_kernel.h
+
+2004-11-30  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: clean up reading functions
+
+2004-11-29  Miklos Szeredi <miklos@szeredi.hu>
+
+	* kernel: make readpage() uninterruptible
+
+	* kernel: check readonly filesystem flag in fuse_permission
+
+	* lib: don't die if version file not found and new style device
+	exists
+
+	* lib: add '-r' option, which is short for '-o ro'
+
+	* fusermount: simplify device opening
+
+	* kernel: when direct_io is turend on, copy data directly to
+	destination without itermediate buffer.  More efficient and safer,
+	since no allocation is done.
+
+	* fusermount: fix warning if fuse module is not loaded
+
+	* kernel: use /dev/fuse on 2.4 too
+
+2004-11-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* libfuse API change: open, read, write, flush, fsync and release
+	are passed a 'struct fuse_file_info' pointer containing the open
+	flags (open and release), and the file handle.  Verion changed to
+	3.0.
+
+2004-11-23  Miklos Szeredi <miklos@szeredi.hu>
+
+	* More cleanups in the kernel
+
+	* The 10,229 charater device number has been assigned for FUSE
+
+	* Version file checking fix (reported by Christian Magnusson)
+
+	* fusermount: opening the fuse device now doesn't need /sys.
+
+	* Optimize reading by controlling the maximum readahead based on
+	the 'max_read' mount option
+
+	* fixes for UCLIBC (Christian Magnusson)
+
+2004-11-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Cleaned up kernel in preparation for merge into mainline:
+
+	* Use /sys/fs/fuse/version instead of /proc/fs/fuse/version
+
+	* Use real device (/dev/fuse) instead of /proc/fs/fuse/dev
+
+	* __user annotations for sparse
+
+	* allocate individual pages instead of kmalloc in fuse_readdir,
+	fuse_read and fuse_write.
+
+	* Fix NFS export in case "use_ino" mount option is given
+
+	* Make libfuse and fusermount compatible with future versions
+
+	* fusermount: properly add mount options to /etc/mtab
+
+2004-11-15  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fusermount: do not resolve last component of mountpoint on if it
+	is '.' or '..'.  This new path resolvation is now done on mount as
+	well as unmount.  This enables relative paths to work on unmount.
+
+	* fusermount: parse common mount options like "ro", "rw", etc...
+
+	* Allow module params to be changed through sysfs
+
+2004-11-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 2.1-pre1
+
+2004-11-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix bug in fuse_readpages() causing Oops in certain situations.
+	Bug found by Vincenzo Ciancia.
+
+	* Fix compilation with kernels versions > 2.6.9.
+
+2004-11-11  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Check kernel interface version in fusermount to prevent
+	strangeness in case of mismatch.
+
+	* No need to allocate fuse_conn until actual mount happens
+
+	* Fix potential race between umount and fuse_invalidate
+
+	* Check superblock of proc file in addition to inode number
+
+	* Fix race between request_send_noreply() and fuse_dev_release()
+
+2004-11-10  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Separate configure for the kernel directory
+
+	* Don't allow write to return more than 'count'
+
+	* Extend kernel interface for future use
+
+2004-11-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix 'makeconf.sh' to use autoreconf if available
+
+2004-11-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add ino argument to 'fuse_dirfil_t'.  NOTE: This breaks source
+	compatibility with earlier versions.  To compile earier versions
+	just add '-DFUSE_DIRFIL_COMPAT' compile flag or fix the source.
+	Do not use the "use_ino" mount flag with filesystems compiled with
+	FUSE_DIRFIL_COMPAT.
+
+	* Add pkg-config support.  To compile a FUSE based filesystem you
+	can do  "gcc -Wall `pkg-config --cflags --libs fuse` myfs.c -o myfs"
+	or similar.  Note, that the PKG_CONFIG_PATH environment variable
+	usually needs to be set to "/usr/local/lib/pkgconfig".
+
+	* fuse.h is now installed in ${prefix}/include/fuse/
+
+2004-11-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added "use_ino" mount option.  This enables the filesystems to
+	set the st_ino field on files
+
+2004-11-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix compile problems with ancient (<=2.4.18) kernels (reported
+	by Jeremy Smith)
+
+	* Add "allow_root" mount option.  Patch by Yaroslav Rastrigin
+
+	* Clear the 'exited' flag when mail loop is finished
+
+2004-10-28  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Make xattr functions work under 2.6 (bug found by Vincenzo
+	Ciancia)
+
+2004-10-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Reset request in fuse_flush() (bugreport by David Shaw)
+
+2004-10-21  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fuse_main() now does not exit on error, rather it returns an
+	error code
+
+	* Exported __fuse_setup() and __fuse_teardown() functions, which
+	make it easier to implement a custom event loop.
+
+	* Use daemon() call to background the filesystem after mounting.
+	This function closes the standard input, output and error and
+	changes the current working directory to "/".
+
+2004-10-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Released 1.9
+
+2004-10-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Don't allow fuse_flush() to be interrupted (bug found by David
+	Shaw)
+
+2004-09-27  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add PID to fuse_context.  Patch by Steven James
+
+	* Change file handle type to 'unsigned long' in kernel interface
+
+2004-09-22  Miklos Szeredi <miklos@szeredi.hu>
+
+	* A slight API change: fuse_get_context() doesn't need the "fuse"
+	pointer, but the returned context contains it instead.  The
+	fuse_get() function is not needed anymore, so it's removed.
+
+	* Fix mounting and umounting FUSE filesystem under another FUSE
+	filesystem by non-root (bug spotted by Valient Gough)
+
+2004-09-21  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix deadlock in case of memory allocation failure.  Patch by
+	Christian Magnusson
+
+2004-09-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Check memory allocation failures in libfuse
+
+2004-09-14  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Check temporary file creation failure in do_getdir().  Bug
+	spotted by Terje Oseberg
+
+2004-09-13  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Allow "large_read" option for 2.6 kernels but warn of deprecation
+
+	* Make requests non-interruptible so race with FORGET is avoided.
+	This is only a temporary solution
+
+	* Support compiling FUSE kernel module on 2.4.x UML kernels
+
+2004-09-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix bug in case two FORGETs for the same node are executed in
+	the wrong order.  Bug spotted and endured for months by Franco
+	Broi, and logfile for solution provided by Terje Oseberg
+
+2004-09-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add -D_REENTRANT to the compile flags
+
+	* Add documentation of fuse internals by Terje Oseberg
+
+2004-08-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Change release method to be non-interruptible.  Fixes bug
+	causing missing release() call when program which has opened files
+	is killed (reported by Franco Broi and David Shaw)
+
+2004-07-29  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add fuse_invalidate() to library API
+
+2004-07-26  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Check permissions in setattr if 'default_permissions' flag is
+	set.  Bug spotted by Damjan Lango
+
+2004-07-24  Miklos Szeredi <miklos@szeredi.hu>
+
+	* 'large_read' mount option removed for 2.6 kernels, since the
+	default (dynamic read size) is better
+
+	* Extend kernel API with file handles.  A file handle is returned
+	by open, and passed to read, write, flush, fsync and release.
+	This is currently only used for debug output in the library.
+
+	* Security changes:
+
+	* Change the current directory to the mountpoint before checking
+	the permissions and mount filesystem on "."
+
+	* By default don't modprobe the fuse module for non-root.  The old
+	behavior can be restored with the '--enable-auto-modprobe' flag of
+	./configure
+
+	* By default don't allow shared writable mappings for non-root.
+	The old behavior can be restored with the 'user_mmap=1' module
+	parameter
+
+2004-07-23  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Clean up mount option passing to fusermount and to fuse_new()
+	BEWARE: this changes the userspace API slightly, and the command
+	line usage of programs using fuse_main()
+
+2004-07-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Optimize reading under 2.6 kernels by issuing multiple page
+	asynchronous read requests
+
+2004-07-18  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Only use redirty_page_for_writepage() for kernels >= 2.6.6
+
+2004-07-16  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Separate directory entry and inode attribute validity timer
+
+	* New write semaphore to stop page writeback during truncate
+
+	* Fsync now waits for all writes to complete before sending the
+	request
+
+	* Optimization: if a page is completely written by
+	fuse_commit_write(), clear the dirty flag and set the uptodate
+	flag for that page
+
+	* Some memory cleanup at exit
+
+2004-07-13  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add FUSE_HARD_REMOVE flag, and '-i' option to fuse main, which
+	disable the "hide if open" behavior of unlink/rename.
+
+	* If temporary buffer allocation fails in raw read, fall back to a
+	smaller buffer
+
+2004-07-12  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix bug in do_open() in libfuse: open count was incremented
+	after the reply is sent so it could race with unlink/forget and
+	cause an abort.
+
+2004-07-08  Miklos Szeredi <miklos@szeredi.hu>
+
+	* When performing create or remove operation, refresh the parent's
+	attributes on next revalidate, as i_nlink (and maybe size/time)
+	could be inacurate.
+
+	* Use redirty_page_for_writepage() in fuse_writepage() for skipped
+	pages (2.6 only)
+
+	* Set set_page_dirty address space operation (2.6 only)
+
+2004-07-06  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Minor fix in read:  print debug info even if read size is zero
+
+2004-07-04  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix race between truncate and writepage (fsx-linux now runs
+	without error)
+
+2004-07-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix kernel hang on mkfifo under 2.4 kernels (spotted and patch
+	by Mattias Wadman)
+
+	* Added option for direct read/write (-r)
+
+	* Fix revalidate time setting for newly created inodes
+
+	* Remove uid==0 check for '-x' option in fusermount (kernel checks
+	this)
+
+	* fuse_main() only installs handlers for signals (out of INT, HUP,
+	TERM, PIPE), for which no handler has yet been installed
+
+	* Add module option 'user_allow_other' which if set to non-zero
+	will allow non root user to specify the 'allow_other' mount option
+	('-x' option of fusermount)
+
+	* Fix deadlock between page writeback completion and truncate
+	(bug found by Valient Gough with the fsx-linux utility)
+
+2004-07-01  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Change passing fuse include dir to 2.6 kernel make system more
+	robust (fixes compile problems seen on SuSE 9.1 with updated 2.6
+	kernel)
+
+2004-06-30  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Acquire inode->i_sem before open and release methods to prevent
+	concurrent rename or unlink operations.
+
+	* Make __fuse_read_cmd() read only one command.  This allows
+	multiplexing the fuse file descriptor with other event sources
+	using select() or poll() (patch by Jeff Harris)
+
+	* Export 'exited' flag with __fuse_exited() (patch by Jeff Harris)
+
+2004-06-27  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix file offset wrap around at 4G when doing large reads
+
+2004-06-24  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix memory leak in open (Valient Gough)
+
+2004-06-24  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add "close after delete" support to libfuse (patch by Valient
+	Gough)
+
+	* Cancel all worker threads before exit in multithreaded mode
+
+2004-06-23  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix locking bugs
+
+	* Don't send reply to RELEASE
+
+	* Work with newer libtool (1.5a)
+
+	* Check for st_atim member of struct stat
+
+2004-06-22  Miklos Szeredi <miklos@szeredi.hu>
+
+	* No request allocation needed on inode and file release
+
+2004-06-21  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix possible inode leak in userspace in case of unfinished
+	lookup/mknod/mkdir/symlink/link operation.
+
+2004-06-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix some races and cleanups in fuse_read_super()
+
+2004-06-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Requests are allocated at open time
+
+2004-06-03  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Build shared library as well as static (using libtool)
+
+	* Change FUSE_MINOR_VERSION from 1 to 0.  I know it's illegal but
+	there has not been a release with the previous minor number, and I
+	hope nobody is using it for anything.
+
+	* Change fuse_main(), so that default behavior is to go into
+	background if mount is successful.  '-f' and '-d' options disable
+	backgrounding.  This fixes the "Why does my FUSE daemon hang?"
+	newbie complaint.
+
+	* Cache ENOSYS (function not implemented) errors on *xattr, flush
+	and fsync
+
+	* Don't call getdir method from open() only from first readdir().
+	Open is sometimes just used to store the current directory
+	(e.g. find)
+
+2004-05-18  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added flush() call
+
+2004-05-04  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Extended attributes support for 2.4 (patch by Cody Pisto)
+
+2004-04-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fixed parser with modversions (Mattias Wadman)
+
+2004-04-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added mount option parser to 2.4 build
+
+2004-04-13  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Replaced binary mount data with text options
+
+	* Show FUSE specific mount options in /proc/mounts

+
+	* Check some limits so userspace won't get too big requests
+
+2004-04-05  Miklos Szeredi <miklos@szeredi.hu>

+	* Kill compile warning
+
+	* Upgraded user-mount patch for 2.6.5

+
+	* fixed zero size case for getxattr and listxattr
+
+2004-03-30  Miklos Szeredi <miklos@szeredi.hu>
+
+	* new fusermount flag '-z': lazy unmount, default is not lazy
+
+	* Extended attributes operations added (getxattr, setxattr,
+	listxattr, removexattr)
+
+2004-03-25  Miklos Szeredi <miklos@szeredi.hu>
+
+	* If filesystem doesn't define a statfs operation, then an
+	all-zero default statfs is returned instead of ENOSYS
+
+2004-03-24  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add FS_BINARY_MOUNTDATA filesystem flag for kernels > 2.6.4
+
+2004-03-09  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Fix for uClinux (Christian Magnusson)
+
+2004-03-02  Miklos Szeredi <miklos@szeredi.hu>
+
+	* fuse_main() adds "-n progname" to the fusermount command line
+
+	* More kernel interface changes:
+
+	* Lookup/getattr return cache timeout values
+
+2004-02-25  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Clean up option parsing in fuse_main()
+
+	* Added fuse_get() function which returns the fuse object created
+	by fuse_main()
+
+2004-02-20  Miklos Szeredi <miklos@szeredi.hu>
+
+	* removed old way of mounting (fusermount mountpoint program)
+
+	* more kernel interface changes:
+
+	* added nanosecond precision to file times
+
+	* removed interface version from mount data
+
+	* added /proc/fs/fuse/version which contains MAJOR.MINOR
+
+2004-02-19  Miklos Szeredi <miklos@szeredi.hu>
+
+	* statfs library API changed to match other methods.  Since this
+	  is not backward compatible FUSE_MAJOR_VERSION is changed to 2
+
+	* kernel interface changes follow:
+
+	* statfs changed to 64 bits, added 'bavail' field
+
+	* add generation number to lookup result
+
+	* optimized mknod/mkdir/symlink/link (no separate lookup is
+	needed)
+
+	* rdev size increased to 32 bits for mknod
+
+	* kernel interface version changed to 3.1
+
+2004-02-18  Miklos Szeredi <miklos@szeredi.hu>
+
+	* user-mount upgraded for 2.6.3 kernel
+
+2004-02-17  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added user-mount.2.6.2-rc3.patch
+
+	* Add FS_SAFE flag to fuse filesystem

+	suid-root
+
+2004-02-12  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Remove MS_PERMISSION mount flag (that means something else now)

+	* Make loopback mount of a fuse file work
+
+2004-02-04  Miklos Szeredi <miklos@szeredi.hu>

+
+	* Properly check if the inode exists in fuse_invalidate
+
+2004-01-27  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Added -q option for fusermount
+
+	* fuse_unmount() now uses -q option of fusermount, so no error is
+	printed if the cause of the program exit is that the filesystem
+	has already been unmounted
+
+	* Fix i_nlink correctness after rmdir/unlink
+
+2004-01-26  Miklos Szeredi <miklos@szeredi.hu>
+

+
+	* Write all pending data before a RELEASE operation
+
+	* Suppress 'Bad file descriptor' warning on exit
+
+	* Replaced fusermount option '-d xxx' with '-n xxx' so it doesn't
+	get confused with '-d' of fuse_main() (sorry about this change)
+
+	* New fusermount option '-l' which enables big reads.  Big reads
+	are now disabled by default.
+
+	* fuse_main() can accept fusermount arguments after a '--'
+
+2004-01-19  Miklos Szeredi <miklos@szeredi.hu>

+
+2004-01-14  Miklos Szeredi <miklos@szeredi.hu>

+	* Implemented fsync support in examples/example.py
+
+	* Implemented 'fsync' and 'statfs' methods in python
+	  interface
+
+2003-12-12  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Make it compile on 2.4.19.
+
+	* Add fsync operation (write file failed on xemacs & vi)
+
+2003-12-12  David McNab <david@rebirthing.co.nz>
+
+	* Added distutils support to the python module, as per standard
+	  python development practice
+
+2003-12-11  Miklos Szeredi <miklos@szeredi.hu>
+
+	* Add file locking for mount/unmount (based on patch by Valient
+	Gough)
+
+2003-12-11  David McNab <david@rebirthing.co.nz>
+
+	* Python filesystem - was broken with python2.3, now fixed:
+	   - changed PyTuple_* calls to PySequence_*, because os.lstat
+	     is no longer returning a pure tuple
+	   - changed PyInt_Check() calls to also call PyLong_Check,
+	     to cover for cases (eg os.lstat) where longs are returned
+	   - Added support for file 'release' handling, which IMO is
+	     essential since this signals to a FS that writes to a file
+	     are complete (and therefore the file can now be disposed of
+	     meaningfully at the python filesystem's discretion)
+	   - Added '__init__' handler to base Fuse class, which allows
+	     your Python class to know the mountpoint and mount args,
+	     as attributes myfs.mountpoint, myfs.optlist, myfs.optdict
+
+	* General:
+	   - added 'mount.fuse' script (in util/ dir), which is meant to be
+	     symlinked from /sbin, and which allows FUSE filesystems to
+	     be mounted with the 'mount' command, and listed in fstab;
+	     also, mount arguments get passed to your filesystem
+
+
+2003-11-04  Miklos Szeredi <miklos@szeredi.hu>

+General Information
+===================
+
+FUSE (Filesystem in Userspace) is a simple interface for userspace
+programs to export a virtual filesystem to the Linux kernel.  FUSE
+also aims to provide a secure method for non privileged users to
+create and mount their own filesystem implementations.
+
+You can download the source code releases from
+
+  http://sourceforge.net/projects/fuse
+
+or alternatively you can use CVS to get the very latest development
+version:
+
+  cvs -d :pserver:anonymous@fuse.cvs.sourceforge.net:/cvsroot/fuse co fuse
+
+
+Dependencies
+============
+
+Linux kernel version 2.6.X where X >= 9.
+
+Alternatively a kernel module from FUSE release 2.5.* can be used with
+this release, which supports kernels >= 2.4.21.
+
+Installation
+============
+
+./configure
+make
+make install
+modprobe fuse
+
+You may also need to add '/usr/local/lib' to '/etc/ld.so.conf' and/or
+run ldconfig.
+
+You'll also need a fuse kernel module, Linux kernels 2.6.14 or later
+contain FUSE support.
+
+For more details see the file 'INSTALL'
+
+How To Use
+==========
+
+FUSE is made up of three main parts:
+
+ - A kernel filesystem module
+
+ - A userspace library
+
+ - A mount/unmount program
+
+
+Here's how to create your very own virtual filesystem in five easy
+steps (after installing FUSE):
+
+  1) Edit the file example/fusexmp.c to do whatever you want...
+
+  2) Build the fusexmp program
+
+  3) run 'example/fusexmp /mnt/fuse -d'
+
+  4) ls -al /mnt/fuse
+
+  5) Be glad
+
+If it doesn't work out, please ask!  Also see the file 'include/fuse.h' for
+detailed documentation of the library interface.
+
+Security
+========
+
+If you run 'make install', the fusermount program is installed
+set-user-id to root.  This is done to allow normal users to mount
+their own filesystem implementations.
+
+There must however be some limitations, in order to prevent Bad User from
+doing nasty things.  Currently those limitations are:
+
+  - The user can only mount on a mountpoint, for which it has write
+    permission
+
+  - The mountpoint is not a sticky directory which isn't owned by the
+    user (like /tmp usually is)
+
+  - No other user (including root) can access the contents of the mounted
+    filesystem.
+
+Configuration
+=============
+
+Some options regarding mount policy can be set in the file
+'/etc/fuse.conf'
+
+Currently these options are:
+
+mount_max = NNN
+
+  Set the maximum number of FUSE mounts allowed to non-root users.
+  The default is 1000.
+
+user_allow_other
+
+  Allow non-root users to specify the 'allow_other' or 'allow_root'
+  mount options.
+
+
+Mount options
+=============
+
+Most of the generic mount options described in 'man mount' are
+supported (ro, rw, suid, nosuid, dev, nodev, exec, noexec, atime,
+noatime, sync async, dirsync).  Filesystems are mounted with
+'-onodev,nosuid' by default, which can only be overridden by a
+privileged user.
+
+These are FUSE specific mount options that can be specified for all
+filesystems:
+
+default_permissions
+
+  By default FUSE doesn't check file access permissions, the
+  filesystem is free to implement it's access policy or leave it to
+  the underlying file access mechanism (e.g. in case of network
+  filesystems).  This option enables permission checking, restricting
+  access based on file mode.  This is option is usually useful
+  together with the 'allow_other' mount option.
+
+allow_other
+
+  This option overrides the security measure restricting file access
+  to the user mounting the filesystem.  So all users (including root)
+  can access the files.  This option is by default only allowed to
+  root, but this restriction can be removed with a configuration
+  option described in the previous section.
+
+allow_root
+
+  This option is similar to 'allow_other' but file access is limited
+  to the user mounting the filesystem and root.  This option and
+  'allow_other' are mutually exclusive.
+
+kernel_cache
+
+  This option disables flushing the cache of the file contents on
+  every open().  This should only be enabled on filesystems, where the
+  file data is never changed externally (not through the mounted FUSE
+  filesystem).  Thus it is not suitable for network filesystems and
+  other "intermediate" filesystems.
+
+  NOTE: if this option is not specified (and neither 'direct_io') data
+  is still cached after the open(), so a read() system call will not
+  always initiate a read operation.
+
+auto_cache
+
+  This option enables automatic flushing of the data cache on open().
+  The cache will only be flushed if the modification time or the size
+  of the file has changed.
+
+large_read
+
+  Issue large read requests.  This can improve performance for some
+  filesystems, but can also degrade performance.  This option is only
+  useful on 2.4.X kernels, as on 2.6 kernels requests size is
+  automatically determined for optimum performance.
+
+direct_io
+
+  This option disables the use of page cache (file content cache) in
+  the kernel for this filesystem.  This has several affects:
+
+     - Each read() or write() system call will initiate one or more
+       read or write operations, data will not be cached in the
+       kernel.
+
+     - The return value of the read() and write() system calls will
+       correspond to the return values of the read and write
+       operations.  This is useful for example if the file size is not
+       known in advance (before reading it).
+
+max_read=N
+
+  With this option the maximum size of read operations can be set.
+  The default is infinite.  Note that the size of read requests is
+  limited anyway to 32 pages (which is 128kbyte on i386).
+
+max_readahead=N
+
+  Set the maximum number of bytes to read-ahead.  The default is
+  determined by the kernel.  On linux-2.6.22 or earlier it's 131072
+  (128kbytes)
+
+max_write=N
+
+  Set the maximum number of bytes in a single write operation.  The
+  default is 128kbytes.  Note, that due to various limitations, the
+  size of write requests can be much smaller (4kbytes).  This
+  limitation will be removed in the future.
+
+async_read
+
+  Perform reads asynchronously. This is the default
+
+sync_read
+
+  Perform all reads (even read-ahead) synchronously.
+
+hard_remove
+
+  The default behavior is that if an open file is deleted, the file is
+  renamed to a hidden file (.fuse_hiddenXXX), and only removed when
+  the file is finally released.  This relieves the filesystem
+  implementation of having to deal with this problem.  This option
+  disables the hiding behavior, and files are removed immediately in
+  an unlink operation (or in a rename operation which overwrites an
+  existing file).
+
+  It is recommended that you not use the hard_remove option. When
+  hard_remove is set, the following libc functions fail on unlinked
+  files (returning errno of ENOENT):
+     - read()
+     - write()
+     - fsync()
+     - close()
+     - f*xattr()
+     - ftruncate()
+     - fstat()
+     - fchmod()
+     - fchown()
+
+debug
+
+  Turns on debug information printing by the library.
+
+fsname=NAME
+
+  Sets the filesystem source (first field in /etc/mtab).  The default
+  is the program name.
+
+subtype=TYPE
+
+  Sets the filesystem type (third field in /etc/mtab).  The default is
+  the program name.
+
+  If the kernel suppports it, /etc/mtab and /proc/mounts will show the
+  filesystem type as "fuse.TYPE"
+
+  If the kernel doesn't support subtypes, the source filed will be
+  "TYPE#NAME", or if fsname option is not specified, just "TYPE".
+
+use_ino
+
+  Honor the 'st_ino' field in getattr() and fill_dir().  This value is
+  used to fill in the 'st_ino' field in the stat()/lstat()/fstat()
+  functions and the 'd_ino' field in the readdir() function.  The
+  filesystem does not have to guarantee uniqueness, however some
+  applications rely on this value being unique for the whole
+  filesystem.
+
+readdir_ino
+
+  If 'use_ino' option is not given, still try to fill in the 'd_ino'
+  field in readdir().  If the name was previously looked up, and is
+  still in the cache, the inode number found there will be used.
+  Otherwise it will be set to '-1'.  If 'use_ino' option is given,
+  this option is ignored.
+
+nonempty
+
+  Allows mounts over a non-empty file or directory.  By default these
+  mounts are rejected (from version 2.3.1) to prevent accidental
+  covering up of data, which could for example prevent automatic
+  backup.
+
+umask=M
+
+  Override the permission bits in 'st_mode' set by the filesystem.
+  The resulting permission bits are the ones missing from the given
+  umask value.  The value is given in octal representation.
+
+uid=N
+
+  Override the 'st_uid' field set by the filesystem.
+
+gid=N
+
+  Override the 'st_gid' field set by the filesystem.
+
+blkdev
+
+  Mount a filesystem backed by a block device.  This is a privileged
+  option.  The device must be specified with the 'fsname=NAME' option.
+
+entry_timeout=T
+
+  The timeout in seconds for which name lookups will be cached. The
+  default is 1.0 second.  For all the timeout options, it is possible
+  to give fractions of a second as well (e.g. "-oentry_timeout=2.8")
+
+negative_timeout=T
+
+  The timeout in seconds for which a negative lookup will be cached.
+  This means, that if file did not exist (lookup retuned ENOENT), the
+  lookup will only be redone after the timeout, and the file/directory
+  will be assumed to not exist until then.  The default is 0.0 second,
+  meaning that caching negative lookups are disabled.
+
+attr_timeout=T
+
+  The timeout in seconds for which file/directory attributes are
+  cached.  The default is 1.0 second.
+
+ac_attr_timeout=T
+
+  The timeout in seconds for which file attributes are cached for the
+  purpose of checking if "auto_cache" should flush the file data on
+  open.   The default is the value of 'attr_timeout'
+
+intr
+
+  Allow requests to be interrupted.  Turning on this option may result
+  in unexpected behavior, if the filesystem does not support request
+  interruption.
+
+intr_signal=NUM
+
+  Specify which signal number to send to the filesystem when a request
+  is interrupted.  The default is 10 (USR1).
+
+modules=M1[:M2...]
+
+  Add modules to the filesystem stack.  Modules are pushed in the
+  order they are specified, with the original filesystem being on the
+  bottom of the stack.
+
+
+Modules distributed with fuse
+-----------------------------
+
+iconv
+`````
+Perform file name character set conversion.  Options are:
+
+from_code=CHARSET
+
+  Character set to convert from (see iconv -l for a list of possible
+  values).  Default is UTF-8.
+
+to_code=CHARSET
+
+  Character set to convert to.  Default is determined by the current
+  locale.
+
+
+subdir
+``````
+Prepend a given directory to each path. Options are:
+
+subdir=DIR
+
+  Directory to prepend to all paths.  This option is mandatory.
+
+rellinks
+
+  Transform absolute symlinks into relative
+
+norellinks
+
+  Do not transform absolute symlinks into relative.  This is the default.
+

+ *
+ * There are three possible actions in case of a match:
+ *
+ * i) An integer (int or unsigned) variable determined by 'offset' is
+ *    set to 'value'
+ *
+ * ii) The processing function is called, with 'value' as the key
+ *
+ * iii) An integer (any) or string (char *) variable determined by
+ *    'offset' is set to the value of an option parameter
+ *
+ * 'offset' should normally be either set to
+ *
+ *  - 'offsetof(struct foo, member)'  actions i) and iii)
+ *
+ *  - -1			      action ii)
+ *
+ * The 'offsetof()' macro is defined in the <stddef.h> header.
+ *
+ * The template determines which options match, and also have an
+ * effect on the action.  Normally the action is either i) or ii), but
+ * if a format is present in the template, then action iii) is
+ * performed.
+ *
+ * The types of templates are:
+ *
+ * 1) "-x", "-foo", "--foo", "--foo-bar", etc.	These match only
+ *   themselves.  Invalid values are "--" and anything beginning
+ *   with "-o"
+ *
+ * 2) "foo", "foo-bar", etc.  These match "-ofoo", "-ofoo-bar" or
+ *    the relevant option in a comma separated option list
+ *
+ * 3) "bar=", "--foo=", etc.  These are variations of 1) and 2)
+ *    which have a parameter
+ *
+ * 4) "bar=%s", "--foo=%lu", etc.  Same matching as above but perform
+ *    action iii).

+ *
+ * 6) "-x %s", etc.  Combination of 4) and 5)

+SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
+-----------------------------------------------------------
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded, 
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
+
+DEFINITIONS

+    <title>libblkid Overview</title>
+    <partintro>
+    <para>
+The libblkid library is used to identify block devices (disks) as to their
+content (e.g.  filesystem type, partitions) as well as extracting additional
+information such as filesystem labels/volume names, partitions, unique
+identifiers/serial numbers, etc.  A common use is to allow use of LABEL= and
+UUID= tags instead of hard-coding specific block device names into
+configuration files.
+    </para>
+    <para>
+The libblkid librray
+was written by Andreas Dilger for the ext2 filesystem utilties, with input
+from Ted Ts'o.  The library was subsequently heavily modified by Ted Ts'o.
+    </para>
+    <para>
+The low-level probing code, topology and partitions support was written
+by Karel Zak. Currently, the library is mainatned by Karel Zak.
+    </para>
+    <para>
+The library is part of the util-linux package since version 2.15 and is
+available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.

+ *  X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
+ *
+ *  Note that we take it "backwards" and put the highest-order term in
+ *  the lowest-order bit.  The X^32 term is "implied"; the LSB is the
+ *  X^31 term, etc.  The X^0 term (usually shown as "+1") results in
+ *  the MSB being 1.
+ *
+ *  Note that the usual hardware shift register implementation, which
+ *  is what we're using (we're merely optimizing it by doing eight-bit
+ *  chunks at a time) shifts bits into the lowest-order term.  In our
+ *  implementation, that means shifting towards the right.  Why do we
+ *  do it this way?  Because the calculated CRC must be transmitted in
+ *  order from highest-order term to lowest-order term.  UARTs transmit
+ *  characters in order from LSB to MSB.  By storing the CRC this way,
+ *  we hand it to the UART in the order low-byte to high-byte; the UART
+ *  sends each low-bit to hight-bit; and the result is transmission bit
+ *  by bit from highest- to lowest-order term without requiring any bit
+ *  shuffling on our part.  Reception works similarly.
+ *
+ *  The feedback terms table consists of 256, 32-bit entries.  Notes
+ *
+ *      The table can be generated at runtime if desired; code to do so
+ *      is shown later.  It might not be obvious, but the feedback
+ *      terms simply represent the results of eight shift/xor opera-
+ *      tions for all combinations of data and CRC register values.
+ *
+ *      The values must be right-shifted by eight bits by the "updcrc"
+ *      logic; the shift must be unsigned (bring in zeroes).  On some
+ *      hardware you could probably optimize the shift in assembler by
+ *      using byte-swap instructions.

+.TH "TERMINAL_COLORS.D" "5" "January 2014" "util-linux" "terminal-colors.d"
+.SH "NAME"
+terminal-colors.d \- Configure output colorization for various utilities
+.SH "SYNOPSIS"
+/etc/terminal-colors\&.d/[[\fIname\fR][@\fIterm\fR]\&.][\fItype\fR]
+.SH "DESCRIPTION"
+Files in this directory determine the default behavior for utilities
+when coloring output.
+
+The
+.I name
+is a utility name.  The name is optional and when none is specified then the
+file is used for all unspecified utilities.
+
+The
+.I term
+is a terminal identifier (the TERM environment variable).
+The terminal identifier is optional and when none is specified then the file
+is used for all unspecified terminals.
+
+The
+.I type
+is a file type.  Supported file types are:
+.TP
+.B disable
+Turns off output colorization for all compatible utilities.
+.TP
+.B enable
+Turns on output colorization; any matching
+.B disable
+files are ignored.
+.TP
+.B scheme
+Specifies colors used for output.  The file format may be specific to the utility,
+the default format is described below.
+.PP
+If there are more files that match for a utility, then the file with the more
+specific filename wins.  For example, the filename "@xterm.scheme" has less
+priority than "dmesg@xterm.scheme".  The lowest priority are those files without a
+utility name and terminal identifier (e.g. "disable").
+
+The user-specific
+.I $XDG_CONFIG_HOME/terminal-colors.d
+or
+.I $HOME/.config/terminal-colors.d
+overrides the global setting.
+
+.SH EXAMPLES
+Disable colors for all compatible utilities:
+.RS
+.br
+.B "touch /etc/terminal-colors.d/disable"
+.br
+.RE
+
+Disable colors for all compatible utils on a vt100 terminal:
+.RS
+.br
+.B "touch /etc/terminal-colors.d/@vt100.disable"
+.br
+.RE
+
+Disable colors for all compatible utils except dmesg(1):
+.RS
+.br
+.B "touch /etc/terminal-colors.d/disable"
+.sp
+.B "touch /etc/terminal-colors.d/dmesg.enable"
+.br
+.RE
+
+.SH DEFAULT SCHEME FILES FORMAT
+The following statement is recognized:
+
+.RS
+.br
+.B "name color-sequence"
+.br
+.RE
+
+The
+.B name
+is a logical name of color sequence (for example "error").  The names are
+specific to the utilities.  For more details always see the COLORS section
+in the man page for the utility.
+
+The
+.B color-sequence
+is a color name, ASCII color sequences or escape sequences.
+
+.SS Color names
+black, blue, brown, cyan, darkgray, gray, green, lightblue, lightcyan
+lightgray, lightgreen, lightmagenta, lightred, magenta, red and yellow
+.SS ANSI color sequences
+The color sequences are composed of sequences of numbers
+separated by semicolons.  The most common codes are:
+.sp
+.RS
+.TS
+l l.
+ 0	to restore default color
+ 1	for brighter colors
+ 4	for underlined text
+ 5	for flashing text
+30	for black foreground
+31	for red foreground
+32	for green foreground
+33	for yellow (or brown) foreground
+34	for blue foreground
+35	for purple foreground
+36	for cyan foreground
+37	for white (or gray) foreground
+40	for black background
+41	for red background
+42	for green background
+43	for yellow (or brown) background
+44	for blue background
+45	for purple background
+46	for cyan background
+47	for white (or gray) background
+.TE
+.RE
+.SS Escape sequences
+To specify control or blank characters in the color sequences,
+C-style \e-escaped notation can be used:
+.sp
+.RS
+.TS
+lb l.
+\ea	Bell (ASCII 7)
+\eb	Backspace (ASCII 8)
+\ee	Escape (ASCII 27)
+\ef	Form feed (ASCII 12)
+\en	Newline (ASCII 10)
+\er	Carriage Return (ASCII 13)
+\et	Tab (ASCII 9)
+\ev	Vertical Tab (ASCII 11)
+\e?	Delete (ASCII 127)
+\e_	Space
+\e\e	Backslash (\e)
+\e^	Caret (^)
+\e#	Hash mark (#)
+.TE
+.RE
+.sp
+Please note that escapes are necessary to enter a space, backslash,
+caret, or any control character anywhere in the string, as well as a
+hash mark as the first character.
+
+For example, to use a red background for alert messages in the output of
+.BR dmesg (1),
+use:
+
+.RS
+.br
+.B "echo 'alert 37;41' >> /etc/terminal-colors.d/dmesg.scheme"
+.br
+.RE
+
+.SS Comments
+Lines where the first non-blank character is a # (hash) are ignored.
+Any other use of the hash character is not interpreted as introducing
+a comment.
+
+.SH FILES
+.B $XDG_CONFIG_HOME/terminal-colors.d
+.br
+.B $HOME/.config/terminal-colors.d
+.br
+.B /etc/terminal-colors.d
+
+.SH ENVIRONMENT
+.IP TERMINAL_COLORS_DEBUG=all

+
+.SH COMPATIBILITY
+The terminal-colors.d functionality is currently supported by all util-linux
+utilities which provides colorized output.  For more details always see the
+COLORS section in the man page for the utility.

+.SH NAME
+libblkid \- block device identification library
+.SH SYNOPSIS
+.B #include <blkid.h>
+.sp
+.B cc
+.I file.c
+.B \-lblkid
+.SH DESCRIPTION
+The
+.B libblkid
+library is used to identify block devices (disks) as to their content (e.g.
+filesystem type) as well as extracting additional information such as
+filesystem labels/volume names, unique identifiers/serial numbers.
+A common use is to allow use of LABEL= and UUID= tags instead of hard-coding
+specific block device names into configuration files.
+.P
+The low-level part of the library also allows to extract information about
+partitions and block device topology.
+.P
+The high-level part of the library keeps information about block devices in a
+cache file and is verified to still be valid before being returned to the user
+(if the user has read permission on the raw block device, otherwise not).
+The cache file also allows unprivileged users (normally anyone other
+than root, or those not in the "disk" group) to locate devices by label/id.
+The standard location of the cache file can be overridden by the
+environment variable BLKID_FILE.
+.P
+In situations where one is getting information about a single known device, it
+does not impact performance whether the cache is used or not (unless you are
+not able to read the block device directly).
+.P
+The high-level part of the library supports two methods to evaluate LABEL/UUID.
+It reads information directly from a block device or read information from
+/dev/disk/by-* udev symlinks.  The udev is preferred method by default.
+.P
+If you are dealing with
+multiple devices, use of the cache is highly recommended (even if empty) as
+devices will be scanned at most one time and the on-disk cache will be
+updated if possible.
+.P
+In some cases (modular kernels), block devices are not even visible until
+after they are accessed the first time, so it is critical that there is
+some way to locate these devices without enumerating only visible devices,
+so the use of the cache file is
+.B required
+in this situation.
+.SH CONFIGURATION FILE
+The standard location of the
+.I /etc/blkid.conf
+config file can be overridden by the environment variable BLKID_CONF.  For more
+details about the config file see
+.BR blkid (8)
+man page.
+.SH AUTHOR
+.B libblkid
+was written by Andreas Dilger for the ext2 filesystem utilties, with input
+from Ted Ts'o.  The library was subsequently heavily modified by Ted Ts'o.
+
+The low-level probing code was rewritten by Karel Zak.

+ * SECTION: alignment
+ * @title: Alignment
+ * @short_description: functions to align partitions and work with disk topology and geometry
+ *
+ * The libfdisk aligns the end of the partitions to make it possible to align
+ * the next partition to the "grain" (see fdisk_get_grain()). The grain is
+ * usually 1MiB (or more for devices where optimal I/O is greater than 1MiB).
+ *
+ * It means that the library does not align strictly to physical sector size
+ * (or minimal or optimal I/O), but it uses greater granularity. It makes
+ * partition tables more portable. If you copy disk layout from 512-sector to
+ * 4K-sector device, all partitions are still aligned to physical sectors.
+ *
+ * This unified concept also makes partition tables more user friendly, all
+ * tables look same, LBA of the first partition is 2048 sectors everywhere, etc.
+ *
+ * It's recommended to not change any alignment or device properties. All is
+ * initialized by default by fdisk_assign_device().
+ *
+ * Note that terminology used by libfdisk is: 
+ *   - device properties: I/O limits (topology), geometry, sector size, ...
+ *   - alignment: first, last LBA, grain, ...
+ *
+ * The alignment setting may be modified by disk label driver.

+/**
+ * SECTION: context
+ * @title: Context
+ * @short_description: stores info about device, labels etc.
+ *
+ * The library distinguish between three types of partitioning objects.
+ *
+ * on-disk data
+ *    - disk label specific
+ *    - probed and read  by disklabel drivers when assign device to the context
+ *      or when switch to another disk label type
+ *    - only fdisk_write_disklabel() modify on-disk data
+ *
+ * in-memory data
+ *    - generic data and disklabel specific data stored in struct fdisk_label
+ *    - all partitioning operations are based on in-memory data only
+ *
+ * struct fdisk_partition
+ *    - provides abstraction to present partitions to users
+ *    - fdisk_partition is possible to gather to fdisk_table container
+ *    - used as unified template for new partitions
+ *    - the struct fdisk_partition is always completely independent object and
+ *      any change to the object has no effect to in-memory (or on-disk) label data

+.SH NAME
+uuid \- DCE compatible Universally Unique Identifier library
+.SH SYNOPSIS
+.B #include <uuid.h>
+.SH DESCRIPTION
+The UUID library is used to generate unique identifiers for objects
+that may be accessible beyond the local system.  This library
+generates UUIDs compatible with those created by the Open Software
+Foundation (OSF) Distributed Computing Environment (DCE) utility
+.BR uuidgen .
+.sp
+The UUIDs generated by this library can be reasonably expected to be
+unique within a system, and unique across all systems.  They could
+be used, for instance, to generate unique HTTP cookies across multiple
+web servers without communication between the servers, and without fear
+of a name clash.

+.TH UUID_GENERATE 3 "May 2009" "util-linux" "Libuuid API"
+.SH NAME
+uuid_generate, uuid_generate_random, uuid_generate_time,
+uuid_generate_time_safe \- create a new unique UUID value
+.SH SYNOPSIS
+.nf
+.B #include <uuid.h>
+.sp
+.BI "void uuid_generate(uuid_t " out );
+.BI "void uuid_generate_random(uuid_t " out );
+.BI "void uuid_generate_time(uuid_t " out );
+.BI "int uuid_generate_time_safe(uuid_t " out );
+.fi
+.SH DESCRIPTION
+The
+.B uuid_generate
+function creates a new universally unique identifier (UUID).  The uuid will
+be generated based on high-quality randomness from
+.IR /dev/urandom ,
+if available.  If it is not available, then
+.B uuid_generate
+will use an alternative algorithm which uses the current time, the
+local ethernet MAC address (if available), and random data generated
+using a pseudo-random generator.
+.sp
+The
+.B uuid_generate_random
+function forces the use of the all-random UUID format, even if
+a high-quality random number generator (i.e.,
+.IR /dev/urandom )
+is not available, in which case a pseudo-random
+generator will be substituted.  Note that the use of a pseudo-random
+generator may compromise the uniqueness of UUIDs
+generated in this fashion.
+.sp
+The
+.B uuid_generate_time
+function forces the use of the alternative algorithm which uses the
+current time and the local ethernet MAC address (if available).
+This algorithm used to be the default one used to generate UUID, but
+because of the use of the ethernet MAC address, it can leak
+information about when and where the UUID was generated.  This can cause
+privacy problems in some applications, so the
+.B uuid_generate
+function only uses this algorithm if a high-quality source of
+randomness is not available.  To guarantee uniqueness of UUIDs generated
+by concurrently running processes, the uuid library uses global
+clock state counter (if the process has permissions to gain exclusive access
+to this file) and/or the
+.B uuidd
+daemon, if it is running already or can be spawned by the process (if
+installed and the process has enough permissions to run it).  If neither of
+these two synchronization mechanisms can be used, it is theoretically possible
+that two concurrently running processes obtain the same UUID(s).  To tell
+whether the UUID has been generated in a safe manner, use
+.BR uuid_generate_time_safe .
+.sp
+The
+.B uuid_generate_time_safe
+is similar to
+.BR uuid_generate_time ,
+except that it returns a value which denotes whether any of the synchronization
+mechanisms (see above) has been used.
+.sp
+The UUID is 16 bytes (128 bits) long, which gives approximately 3.4x10^38
+unique values (there are approximately 10^80 elementary particles in
+the universe according to Carl Sagan's
+.IR Cosmos ).
+The new UUID can reasonably be considered unique among all UUIDs created
+on the local system, and among UUIDs created on other systems in the past
+and in the future.
+.SH RETURN VALUE
+The newly created UUID is returned in the memory location pointed to by
+.IR out .
+.B uuid_generate_time_safe
+returns zero if the UUID has been generated in a safe manner, \-1 otherwise.

+ * @short_description: basic routines to work with libblkid cache
+ *
+ * Block device information is normally kept in a cache file blkid.tab and is
+ * verified to still be valid before being returned to the user (if the user has
+ * read permission on the raw block device, otherwise not).  The cache file also
+ * allows unprivileged users (normally anyone other than root, or those not in the
+ * "disk" group) to locate devices by label/id.  The standard location of the
+ * cache file can be overridden by the environment variable BLKID_FILE.
+ *
+ * In situations where one is getting information about a single known device, it
+ * does not impact performance whether the cache is used or not (unless you are
+ * not able to read the block device directly).  If you are dealing with multiple
+ * devices, use of the cache is highly recommended (even if empty) as devices will
+ * be scanned at most one time and the on-disk cache will be updated if possible.
+ * There is rarely a reason not to use the cache.
+ *
+ * In some cases (modular kernels), block devices are not even visible until after
+ * they are accessed the first time, so it is critical that there is some way to
+ * locate these devices without enumerating only visible devices, so the use of
+ * the cache file is required in this situation.

+ * 2.6 systems and on systems with or without udev. Currently, the libblkid
+ * library supports "udev" and "scan" methods. The "udev" method uses udev
+ * /dev/disk/by-* symlinks and the "scan" method scans all block devices from
+ * the /proc/partitions file. The evaluation could be controlled by the
+ * /etc/blkid.conf config file. The default is to try "udev" and then "scan"
+ * method.
+ *
+ * The blkid_evaluate_tag() also automatically informs udevd when an obsolete
+ * /dev/disk/by-* symlink is detected.
+ *
+ * If you are not sure how translate LABEL or UUID to the device name use this
+ * API.

+ * SECTION: partitions

+ * @short_description: partitions tables detection and parsing
+ *
+ * This chain supports binary and NAME=value interfaces, but complete PT
+ * description is provided by binary interface only. The libblkid prober is
+ * compatible with kernel partition tables parser. The parser does not return
+ * empty (size=0) partitions or special hidden partitions.
+ *
+ * NAME=value interface, supported tags:
+ *
+ * @PTTYPE: partition table type (dos, gpt, etc.).
+ *
+ * @PTUUID: partition table id (uuid for gpt, hex for dos).
+
+ * @PART_ENTRY_SCHEME: partition table type
+ *
+ * @PART_ENTRY_NAME: partition name (gpt and mac only)
+ *
+ * @PART_ENTRY_UUID: partition UUID (gpt, or pseudo IDs for MBR)
+ *
+ * @PART_ENTRY_TYPE: partition type, 0xNN (e.g 0x82) or type UUID (gpt only) or type string (mac)
+ *
+ * @PART_ENTRY_FLAGS: partition flags (e.g. boot_ind) or  attributes (e.g. gpt attributes)
+ *
+ * @PART_ENTRY_NUMBER: partition number
+ *
+ * @PART_ENTRY_OFFSET: the begin of the partition
+ *
+ * @PART_ENTRY_SIZE: size of the partition
+ *
+ * @PART_ENTRY_DISK: whole-disk maj:min
+ *
+ * Example:
+ *
+ * <informalexample>
+ *  <programlisting>
+ * blkid_probe pr;
+ * const char *ptname;
+ *
+ * pr = blkid_new_probe_from_filename(devname);

+ * blkid_probe_enable_partitions(pr, TRUE);
+ * blkid_do_fullprobe(pr);
+ *
+ * blkid_probe_lookup_value(pr, "PTTYPE", &ptname, NULL);
+ * printf("%s partition type detected\n", pttype);
+ *
+ * blkid_free_probe(pr);
+ *
+ * // don't forget to check return codes in your code!
+ *  </programlisting>
+ * </informalexample>
+ *
+ * Binary interface:

+/**
+ * SECTION: lowprobe
+ * @title: Low-level probing
+ * @short_description: low-level prober initialization
+ *
+ * The low-level probing routines always and directly read information from
+ * the selected (see blkid_probe_set_device()) device.
+ *
+ * The probing routines are grouped together into separate chains. Currently,
+ * the library provides superblocks, partitions and topology chains.
+ *
+ * The probing routines is possible to filter (enable/disable) by type (e.g.
+ * fstype "vfat" or partype "gpt") or by usage flags (e.g. BLKID_USAGE_RAID).
+ * These filters are per-chain. Note that always when you touch the chain
+ * filter the current probing position is reset and probing starts from
+ * scratch.  It means that the chain filter should not be modified during
+ * probing, for example in loop where you call blkid_do_probe().
+ *
+ * For more details see the chain specific documentation.
+ *
+ * The low-level API provides two ways how access to probing results.
+ *
+ *   1. The NAME=value (tag) interface. This interface is older and returns all data
+ *      as strings. This interface is generic for all chains.
+ *
+ *   2. The binary interfaces. These interfaces return data in the native formats.
+ *      The interface is always specific to the probing chain.
+ *
+ *  Note that the previous probing result (binary or NAME=value) is always
+ *  zeroized when a chain probing function is called. For example:
+ *
+ * <informalexample>
+ *   <programlisting>
+ *     blkid_probe_enable_partitions(pr, TRUE);
+ *     blkid_probe_enable_superblocks(pr, FALSE);
+ *
+ *     blkid_do_safeprobe(pr);
+ *   </programlisting>
+ * </informalexample>
+ *
+ * overwrites the previous probing result for the partitions chain, the superblocks
+ * result is not modified.
+ */
+
+/**
+ * SECTION: lowprobe-tags
+ * @title: Low-level tags
+ * @short_description: generic NAME=value interface.
+ *
+ * The probing routines inside the chain are mutually exclusive by default --
+ * only few probing routines are marked as "tolerant". The "tolerant" probing
+ * routines are used for filesystem which can share the same device with any
+ * other filesystem. The blkid_do_safeprobe() checks for the "tolerant" flag.
+ *
+ * The SUPERBLOCKS chain is enabled by default. The all others chains is
+ * necessary to enable by blkid_probe_enable_'CHAINNAME'(). See chains specific
+ * documentation.
+ *
+ * The blkid_do_probe() function returns a result from only one probing
+ * routine, and the next call from the next probing routine. It means you need
+ * to call the function in loop, for example:
+ *
+ * <informalexample>
+ *   <programlisting>
+ *	while((blkid_do_probe(pr) == 0)
+ *		... use result ...
+ *   </programlisting>
+ * </informalexample>
+ *
+ * The blkid_do_safeprobe() is the same as blkid_do_probe(), but returns only
+ * first probing result for every enabled chain. This function checks for
+ * ambivalent results (e.g. more "intolerant" filesystems superblocks on the
+ * device).
+ *
+ * The probing result is set of NAME=value pairs (the NAME is always unique).

+ * @title: Superblocks probing
+ * @short_description: filesystems and raids superblocks probing.
+ *
+ * The library API has been originally designed for superblocks probing only.
+ * This is reason why some *deprecated* superblock specific functions don't use
+ * '_superblocks_' namespace in the function name. Please, don't use these
+ * functions in new code.
+ *
+ * The 'superblocks' probers support NAME=value (tags) interface only. The
+ * superblocks probing is enabled by default (and controlled by
+ * blkid_probe_enable_superblocks()).
+ *
+ * Currently supported tags:
+ *
+ * @TYPE: filesystem type
+ *
+ * @SEC_TYPE: secondary filesystem type
+ *
+ * @LABEL: filesystem label
+ *
+ * @LABEL_RAW: raw label from FS superblock
+ *
+ * @UUID: filesystem UUID (lower case)
+ *
+ * @UUID_SUB: subvolume uuid (e.g. btrfs)
+ *
+ * @LOGUUID: external log UUID (e.g. xfs)
+ *
+ * @UUID_RAW: raw UUID from FS superblock
+ *
+ * @EXT_JOURNAL: external journal UUID
+ *
+ * @USAGE:  usage string: "raid", "filesystem", ...
+ *
+ * @VERSION: filesystem version
+ *
+ * @MOUNT: cluster mount name (?) -- ocfs only
+ *
+ * @SBMAGIC: super block magic string
+ *
+ * @SBMAGIC_OFFSET: offset of SBMAGIC
+ *
+ * @FSSIZE: size of filessystem [not-implemented yet]
+ *
+ * @SYSTEM_ID: ISO9660 system identifier
+ *
+ * @PUBLISHER_ID: ISO9660 publisher identifier

+ *
+ * NAME=value (tags) interface is enabled by blkid_probe_enable_topology(),
+ * and provides:
+ *
+ * @LOGICAL_SECTOR_SIZE: this is the smallest unit the storage device can
+ *                       address. It is typically 512 bytes.
+ *
+ * @PHYSICAL_SECTOR_SIZE: this is the smallest unit a physical storage device
+ *                        can write atomically. It is usually the same as the
+ *                        logical sector size but may be bigger.
+ *
+ * @MINIMUM_IO_SIZE: minimum size which is the device's preferred unit of I/O.
+ *                   For RAID arrays it is often the stripe chunk size.
+ *
+ * @OPTIMAL_IO_SIZE: usually the stripe width for RAID or zero. For RAID arrays
+ *                   it is usually the stripe width or the internal track size.
+ *
+ * @ALIGNMENT_OFFSET: indicates how many bytes the beginning of the device is
+ *                    offset from the disk's natural alignment.
+ *
+ * The NAME=value tags are not defined when the corresponding topology value
+ * is zero. The MINIMUM_IO_SIZE should be always defined if kernel provides

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+** --------------------------------------------
+** Support for Arm64 in GGLAssembler JIT
+** --------------------------------------------
+**
+** Approach
+** - GGLAssembler and associated files are largely un-changed.
+** - A translator class maps ArmAssemblerInterface calls to
+**   generate Arm64 instructions.
+**
+** ----------------------
+** ArmToArm64Assembler
+** ----------------------
+**
+** - Subclassed from ArmAssemblerInterface
+**
+** - Translates each ArmAssemblerInterface call to generate
+**   one or more Arm64 instructions  as necessary.
+**
+** - Does not implement ArmAssemblerInterface portions unused by GGLAssembler
+**   It calls NOT_IMPLEMENTED() for such cases, which in turn logs
+**    a fatal message.
+**
+** - Uses A64_.. series of functions to generate instruction machine code
+**   for Arm64 instructions. These functions also log the instruction
+**   to LOG, if ARM64_ASM_DEBUG define is set to 1
+**
+** - Dumps machine code and eqvt assembly if "debug.pf.disasm" option is set
+**   It uses arm64_disassemble to perform disassembly
+**
+** - Uses register 13 (SP in ARM), 15 (PC in ARM), 16, 17 for storing
+**   intermediate results. GGLAssembler does not use SP and PC as these
+**   registers are marked as reserved. The temporary registers are not
+**   saved/restored on stack as these are caller-saved registers in Arm64
+**
+** - Uses CSEL instruction to support conditional execution. The result is
+**   stored in a temporary register and then copied to the target register
+**   if the condition is true.
+**
+** - In the case of conditional data transfer instructions, conditional
+**   branch is used to skip over instruction, if the condition is false
+**
+** - Wherever possible, immediate values are transferred to temporary
+**   register prior to processing. This simplifies overall implementation
+**   as instructions requiring immediate values are converted to
+**   move immediate instructions followed by register-register instruction.
+**
+** --------------------------------------------
+** ArmToArm64Assembler unit test bench
+** --------------------------------------------
+**
+** - Tests ArmToArm64Assembler interface for all the possible
+**   ways in which GGLAssembler uses ArmAssemblerInterface interface.
+**
+** - Uses test jacket (written in assembly) to set the registers,
+**   condition flags prior to calling generated instruction. It also
+**   copies registers and flags at the end of execution. Caller then
+**   checks if generated code performed correct operation based on
+**   output registers and flags.
+**
+** - Broadly contains three type of tests, (i) data operation tests
+**   (ii) data transfer tests and (iii) LDM/STM tests.
+**
+** ----------------------
+** Arm64 disassembler
+** ----------------------
+** - This disassembler disassembles only those machine codes which can be
+**   generated by ArmToArm64Assembler. It has a unit testbench which
+**   tests all the instructions supported by the disassembler.
+**
+** ------------------------------------------------------------------
+** ARMAssembler/ARMAssemblerInterface/ARMAssemblerProxy changes
+** ------------------------------------------------------------------
+**
+** - In existing code, addresses were being handled as 32 bit values at
+**   certain places.
+**
+** - Added a new set of functions for address load/store/manipulation.
+**   These are ADDR_LDR, ADDR_STR, ADDR_ADD, ADDR_SUB and they map to
+**   default 32 bit implementations in ARMAssemblerInterface.
+**
+** - ArmToArm64Assembler maps these functions to appropriate 64 bit
+**   functions.
+**
+** ----------------------
+** GGLAssembler changes
+** ----------------------
+** - Since ArmToArm64Assembler can generate 4 Arm64 instructions for
+**   each call in worst case, the memory required is set to 4 times
+**   ARM memory
+**
+** - Address load/store/manipulation were changed to use new functions
+**   added in the ARMAssemblerInterface.

+/* MIPS assembler and ARM->MIPS assembly translator
+**
+** The approach is to leave the GGLAssembler and associated files largely
+** un-changed, still utilizing all Arm instruction generation. Via the
+** ArmToMipsAssembler (subclassed from ArmAssemblerInterface) each Arm
+** instruction is translated to one or more Mips instructions as necessary. This
+** is clearly less efficient than a direct implementation within the
+** GGLAssembler, but is far cleaner, more maintainable, and has yielded very
+** significant performance gains on Mips compared to the generic pixel pipeline.
+**
+**
+** GGLAssembler changes
+**
+** - The register allocator has been modified to re-map Arm registers 0-15 to mips
+** registers 2-17. Mips register 0 cannot be used as general-purpose register,
+** and register 1 has traditional uses as a short-term temporary.
+**
+** - Added some early bailouts for OUT_OF_REGISTERS in texturing.cpp and
+** GGLAssembler.cpp, since this is not fatal, and can be retried at lower
+** optimization level.
+**
+**
+** ARMAssembler and ARMAssemblerInterface changes
+**
+** Refactored ARM address-mode static functions (imm(), reg_imm(), imm12_pre(), etc.)
+** to virtual, so they can be overridden in MIPSAssembler. The implementation of these
+** functions on ARM is moved from ARMAssemblerInterface.cpp to ARMAssembler.cpp, and
+** is unchanged from the original. (This required duplicating 2 of these as static
+** functions in ARMAssemblerInterface.cpp so they could be used as static initializers).

+	NOTE:
+	All releases below marked (Chris Frey) are maintenance releases
+	done by Chris Frey, temporarily stepping in for Mark Roth.
+	These releases are git-based only and can be found at:
+		http://repo.or.cz/w/libtar.git
+
+	Both git downloads and tarball downloads are possible at this site.
+
+
+libtar 1.2.20 - 2013/10/09 (Chris Frey)
+-------------
+      Added extern "C" protectors to listhash.h
+      Added autoconf checks for __thread compiler support
+      Fixed size_t overflow bug, as reported by Timo Warns
+      Fixed thread-safe bug in th_get_pathname() (Sergey Zhitomirsky)
+
+
+libtar 1.2.19 - 2012/12/11 (Chris Frey)
+-------------
+      Removed varargs.h and all dependencies, to avoid user compile errors
+
+      Fixed some short int / int compiler warnings in va_arg() usage
+
+      Fixed some gcc built-in compiler warnings
+
+      Changed autoconf support code from AC_RUN_ to AC_COMPILE_ to fix
+      issues reported during cross-compiling.
+
+      Applied most of Jan Cermak's const char* function argument patch.
+
+
+libtar 1.2.18 - 2012/08/02 (Chris Frey)
+-------------
+      Added more forgiving CRC checking logic when reading tar files
+
+      Note: If your application uses the macro th_crc_ok(), then to gain full
+      advantage of the changes in this version, you will need to recompile
+      your application against the new headers.  Otherwise, the library is
+      drop-in replaceable, as usual.
+
+
+libtar 1.2.17 - 2012/07/24 (Chris Frey)
+-------------
+      Applied Tim Band's checksum patch from mailing list (thanks!)

+
+
+libtar 1.2.15 - 2012/05/10 (Chris Frey)
+-------------
+Chris Frey (1):
+      Fixed harmless buffer overflow which is caught by FORTIFY on some systems
+
+
+libtar 1.2.14 - 2011/12/22 (Chris Frey)
+-------------

+
+
+libtar 1.2.13 - 2011/06/13 (Chris Frey)
+-------------
+Chris Frey (10):
+      Fixed incorrect URL in readme
+      Added autoconf/ as macro dir
+      Added autogen.sh script to build a fresh configure
+      Renamed autoconf/aclocal.m4 to psg.m4 so aclocal isn't so confused
+      Removed m4 includes, and straightened out [] m4 quoting for modern autoconfs
+      Removed auto-generated files
+      Added datarootdir to Makefile.in's
+      Fixed header warnings
+      Applied Marcin Gibula's patch fixing tar_extract_glob()
+      Changed root Makefile.in to Makefile.am, which make autoreconf workable
+
+Glenn McGrath (1):
+      Use libtool to build dynamic library
+
+James Morrison (1):
+      Document stupidity of tartype_t in libtar.c.
+

+Basic Installation
+==================
+
+   These are generic installation instructions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+   The file `configure.in' is used to create `configure' by a program
+called `autoconf'.  You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory.  After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on.  Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+     CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+   If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+libtar - C library for manipulating tar files
+======
+
+libtar is a library for manipulating tar files from within C programs.
+Here are some of its features:
+
+  * Handles both POSIX tar file format and the GNU extensions.
+  * API provides functions for easy use, such as tar_extract_all().
+  * Also provides functions for more granular use, such as 
+    tar_append_regfile().
+
+
+Installation
+------------
+
+To build libtar, you should be able to simply run these commands:
+
+   ./configure
+   make
+   make install
+
+
+Encap Package Support
+---------------------
+
+To build this software as an Encap package, you can pass the
+--enable-encap option to configure.  This will be automatically
+enabled if the epkg or mkencap programs are detected on the system,
+but can be overridden by the --disable-encap option.
+
+When building an Encap package, the configure script will automatically
+adjust the installation prefix to use an appropriate Encap package
+directory.  It does this using a heuristic algorithm which examines the
+values of the ${ENCAP_SOURCE} and ${ENCAP_TARGET} environment variables
+and the argument to configure's --prefix option.
+
+If mkencap was detected on the system, it will be automatically run during
+"make install".  By default, epkg will also be run, but this can be
+inhibited with the --disable-epkg-install configure option.
+
+For information on the Encap package management system, see the WSG
+Encap Archive:
+
+   http://www.encap.org/
+
+
+zlib Support
+------------
+
+The configure script will attempt to find the zlib library on your system
+for use with the libtar driver program.  The zlib package is available from:
+
+   http://www.gzip.org/zlib/
+
+If zlib is installed on your system, but you do not wish to use it,
+specify the --without-zlib option when you invoke configure.
+
+
+More Information
+----------------
+
+For documentation of the libtar API, see the enclosed manpages.  For more
+information on the libtar package, see:
+
+   http://www-dev.cites.uiuc.edu/libtar/
+
+Source code for the latest version of libtar will be available there, as
+well as Encap binary distributions for many common platforms.
+
+
+Supported Platforms
+-------------------
+
+I develop and test libtar on the following platforms:
+
+   AIX 4.3.3 and 5.1
+   HP-UX 11.00
+   IRIX 6.5
+   RedHat Linux 7.2
+   Solaris 8 and 9
+
+It should also build on the following platforms, but I do not actively
+support them:
+
+   AIX 3.2.5
+   AIX 4.2.1
+   Cygwin
+   FreeBSD
+   HP-UX 10.20
+   Linux/libc5
+   OpenBSD
+   Solaris 2.5
+   Solaris 2.6
+   Solaris 7
+
+If you successfully build libtar on another platform, please email me a
+patch and/or configuration information.
+
+
+Compatibility Code
+------------------
+
+libtar depends on some library calls which are not available or not
+usable on some platforms.  To accomodate these systems, I've included
+a version of these calls in the compat subdirectory.
+
+I've slightly modified these functions for integration into this source
+tree, but the functionality has not been modified from the original
+source.  Please note that while this code should work for you, I didn't
+write it, so please don't send me bug reports on it.

+/**************************************************************
+ * Original:
+ * Patrick Powell Tue Apr 11 09:48:21 PDT 1995
+ * A bombproof version of doprnt (dopr) included.
+ * Sigh.  This sort of thing is always nasty do deal with.  Note that
+ * the version here does not include floating point...
+ *
+ * snprintf() is used instead of sprintf() as it does limit checks
+ * for string length.  This covers a nasty loophole.
+ *
+ * The other functions are there to prevent NULL pointers from
+ * causing nast effects.
+ *
+ * More Recently:
+ *  Brandon Long <blong@fiction.net> 9/15/96 for mutt 0.43
+ *  This was ugly.  It is still ugly.  I opted out of floating point
+ *  numbers, but the formatter understands just about everything
+ *  from the normal C string format, at least as far as I can tell from
+ *  the Solaris 2.5 printf(3S) man page.
+ *
+ *  Brandon Long <blong@fiction.net> 10/22/97 for mutt 0.87.1
+ *    Ok, added some minimal floating point support, which means this
+ *    probably requires libm on most operating systems.  Don't yet
+ *    support the exponent (e,E) and sigfig (g,G).  Also, fmtint()
+ *    was pretty badly broken, it just wasn't being exercised in ways
+ *    which showed it, so that's been fixed.  Also, formated the code
+ *    to mutt conventions, and removed dead code left over from the
+ *    original.  Also, there is now a builtin-test, just compile with:
+ *           gcc -DTEST_SNPRINTF -o snprintf snprintf.c -lm
+ *    and run snprintf for results.
+ * 
+ *  Thomas Roessler <roessler@guug.de> 01/27/98 for mutt 0.89i
+ *    The PGP code was using unsigned hexadecimal formats. 
+ *    Unfortunately, unsigned formats simply didn't work.
+ *
+ *  Michael Elkins <me@cs.hmc.edu> 03/05/98 for mutt 0.90.8
+ *    The original code assumed that both snprintf() and vsnprintf() were
+ *    missing.  Some systems only have snprintf() but not vsnprintf(), so
+ *    the code is now broken down under HAVE_SNPRINTF and HAVE_VSNPRINTF.
+ *
+ *  Chris Frey <cdfrey@foursquare.net> 2012/09/05
+ *    Removed varargs.h and all dependency on it.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+
+Introduction
+------------
+
+OpenAES is an open source implementation of the Advanced Encryption
+Standard.  It is distributed as a portable, lightweight C library that can
+be easily integrated into applications.
+
+Compiling
+---------
+
+OpenAES has been tested with the GCC as well as VC compilers.  It is
+necessary to compile the source files located in ./src, and to add ./inc to
+the include paths.
+
+If you are building with OAES_HAVE_ISAAC defined (true by default), then
+you also need to link in the source files under ./src/isaac and also add
+./src/isaac to the include paths.
+
+You may edit ./inc/oaes_config.h to modify build options.
+
+CMake 2.8.0 can be used to build the test programs on different platforms.
+
+In a Linux command line terminal type:
+
+cmake .
+make
+
+In Windows, in a Visual Studio command line window type:
+
+cmake . -G "NMake Makefiles"
+nmake
+
+Usage
+-----
+
+Usage is described in the header file ./inc/oaes_lib.h.
+
+Samples
+-------
+
+Samples applications are provided in the /test folder.

+pigz 2.2.5 (xx Apr 2012) by Mark Adler
+
+pigz, which stands for Parallel Implementation of GZip, is a fully functional
+replacement for gzip that exploits multiple processors and multiple cores to
+the hilt when compressing data.
+
+pigz was written by Mark Adler, and uses the zlib and pthread libraries.
+
+This version of pigz is written to be portable across Unix-style operating
+systems that provide the zlib and pthread libraries.
+
+Type "make" in this directory to build the "pigz" executable.  You can then
+install the executable wherever you like in your path (e.g. /usr/local/bin/).
+Type "pigz" to see the command help and all of the command options.
+
+The latest version of pigz can be found at http://zlib.net/pigz/ .  You need
+zlib version 1.2.3 or later to compile pigz.  You can find the latest version
+of zlib at http://zlib.net/ .  You can look in pigz.c for the change history.
+
+Questions, comments, bug reports, fixes, etc. can be emailed to Mark at his
+address in the license below.

+.SH DESCRIPTION
+.I Pigz
+compresses using threads to make use of multiple processors and cores.
+The input is broken up into 128 KB chunks with each compressed in parallel.
+The individual check value for each chunk is also calculated in parallel.
+The compressed data is written in order to the output, and a combined check
+value is calculated from the individual check values.
+.PP
+The compressed data format generated is in the gzip, zlib, or single-entry
+zip format using the deflate compression method.  The compression produces
+partial raw deflate streams which are concatenated by a single write thread
+and wrapped with the appropriate header and trailer, where the trailer
+contains the combined check value.
+.PP
+Each partial raw deflate stream is terminated by an empty stored block
+(using the Z_SYNC_FLUSH option of zlib), in order to end that partial bit
+stream at a byte boundary.  That allows the partial streams to be
+concatenated simply as sequences of bytes.  This adds a very small four to
+five byte overhead to the output for each input chunk.
+.PP
+The default input block size is 128K, but can be changed with the
+.B -b
+option.  The number of compress threads is set by default to the number
+of online processors,
+which can be changed using the
+.B -p
+option.  Specifying
+.B -p 1
+avoids the use of threads entirely.
+.PP
+The input blocks, while compressed independently, have the last 32K of the
+previous block loaded as a preset dictionary to preserve the compression
+effectiveness of deflating in a single thread.  This can be turned off using
+the
+.B -i
+or
+.B --independent
+option, so that the blocks can be decompressed
+independently for partial error recovery or for random access.
+.PP
+Decompression can't be parallelized, at least not without specially prepared
+deflate streams for that purpose.  As a result,
+.I pigz
+uses a single thread
+(the main thread) for decompression, but will create three other threads for
+reading, writing, and check calculation, which can speed up decompression
+under some circumstances.  Parallel decompression can be turned off by
+specifying one process
+(
+.B -dp 1
+or
+.B -tp 1
+).
+.PP
+Compressed files can be restored to their original form using
+.I pigz -d
+or
+.I unpigz.
+
+.SH OPTIONS
+.TP
+.B -# --fast --best
+Regulate the speed of compression using the specified digit
+.IR # ,
+where
+.B \-1

+
+/*
+   pigz compresses using threads to make use of multiple processors and cores.
+   The input is broken up into 128 KB chunks with each compressed in parallel.
+   The individual check value for each chunk is also calculated in parallel.
+   The compressed data is written in order to the output, and a combined check
+   value is calculated from the individual check values.
+
+   The compressed data format generated is in the gzip, zlib, or single-entry
+   zip format using the deflate compression method.  The compression produces
+   partial raw deflate streams which are concatenated by a single write thread
+   and wrapped with the appropriate header and trailer, where the trailer
+   contains the combined check value.
+
+   Each partial raw deflate stream is terminated by an empty stored block
+   (using the Z_SYNC_FLUSH option of zlib), in order to end that partial bit
+   stream at a byte boundary, unless that partial stream happens to already end
+   at a byte boundary (the latter requires zlib 1.2.6 or later).  Ending on a
+   byte boundary allows the partial streams to be concatenated simply as
+   sequences of bytes.  This adds a very small four to five byte overhead
+   (average 3.75 bytes) to the output for each input chunk.
+
+   The default input block size is 128K, but can be changed with the -b option.
+   The number of compress threads is set by default to 8, which can be changed
+   using the -p option.  Specifying -p 1 avoids the use of threads entirely.
+   pigz will try to determine the number of processors in the machine, in which
+   case if that number is two or greater, pigz will use that as the default for
+   -p instead of 8.
+
+   The input blocks, while compressed independently, have the last 32K of the
+   previous block loaded as a preset dictionary to preserve the compression
+   effectiveness of deflating in a single thread.  This can be turned off using
+   the --independent or -i option, so that the blocks can be decompressed
+   independently for partial error recovery or for random access.
+
+   Decompression can't be parallelized, at least not without specially prepared
+   deflate streams for that purpose.  As a result, pigz uses a single thread
+   (the main thread) for decompression, but will create three other threads for
+   reading, writing, and check calculation, which can speed up decompression
+   under some circumstances.  Parallel decompression can be turned off by
+   specifying one process (-dp 1 or -tp 1).
+
+   pigz requires zlib 1.2.1 or later to allow setting the dictionary when doing
+   raw deflate.  Since zlib 1.2.3 corrects security vulnerabilities in zlib
+   version 1.2.1 and 1.2.2, conditionals check for zlib 1.2.3 or later during
+   the compilation of pigz.c.  zlib 1.2.4 includes some improvements to
+   Z_FULL_FLUSH and deflateSetDictionary() that permit identical output for
+   pigz with and without threads, which is not possible with zlib 1.2.3.  This
+   may be important for uses of pigz -R where small changes in the contents
+   should result in small changes in the archive for rsync.  Note that due to
+   the details of how the lower levels of compression result in greater speed,
+   compression level 3 and below does not permit identical pigz output with
+   and without threads.
+
+   pigz uses the POSIX pthread library for thread control and communication,
+   through the yarn.h interface to yarn.c.  yarn.c can be replaced with
+   equivalent implementations using other thread libraries.  pigz can be
+   compiled with NOTHREAD #defined to not use threads at all (in which case
+   pigz will not be able to live up to the "parallel" in its name).
+ */
+
+/*
+   Details of parallel compression implementation:
+
+   When doing parallel compression, pigz uses the main thread to read the input
+   in 'size' sized chunks (see -b), and puts those in a compression job list,
+   each with a sequence number to keep track of the ordering.  If it is not the
+   first chunk, then that job also points to the previous input buffer, from
+   which the last 32K will be used as a dictionary (unless -i is specified).
+   This sets a lower limit of 32K on 'size'.
+
+   pigz launches up to 'procs' compression threads (see -p).  Each compression
+   thread continues to look for jobs in the compression list and perform those
+   jobs until instructed to return.  When a job is pulled, the dictionary, if
+   provided, will be loaded into the deflate engine and then that input buffer
+   is dropped for reuse.  Then the input data is compressed into an output
+   buffer that grows in size if necessary to hold the compressed data. The job
+   is then put into the write job list, sorted by the sequence number. The
+   compress thread however continues to calculate the check value on the input
+   data, either a CRC-32 or Adler-32, possibly in parallel with the write
+   thread writing the output data.  Once that's done, the compress thread drops
+   the input buffer and also releases the lock on the check value so that the
+   write thread can combine it with the previous check values.  The compress
+   thread has then completed that job, and goes to look for another.
+
+   All of the compress threads are left running and waiting even after the last
+   chunk is processed, so that they can support the next input to be compressed
+   (more than one input file on the command line).  Once pigz is done, it will
+   call all the compress threads home (that'll do pig, that'll do).
+
+   Before starting to read the input, the main thread launches the write thread
+   so that it is ready pick up jobs immediately.  The compress thread puts the
+   write jobs in the list in sequence sorted order, so that the first job in
+   the list is always has the lowest sequence number.  The write thread waits
+   for the next write job in sequence, and then gets that job.  The job still
+   holds its input buffer, from which the write thread gets the input buffer
+   length for use in check value combination.  Then the write thread drops that
+   input buffer to allow its reuse.  Holding on to the input buffer until the
+   write thread starts also has the benefit that the read and compress threads
+   can't get way ahead of the write thread and build up a large backlog of
+   unwritten compressed data.  The write thread will write the compressed data,
+   drop the output buffer, and then wait for the check value to be unlocked
+   by the compress thread.  Then the write thread combines the check value for
+   this chunk with the total check value for eventual use in the trailer.  If
+   this is not the last chunk, the write thread then goes back to look for the
+   next output chunk in sequence.  After the last chunk, the write thread
+   returns and joins the main thread.  Unlike the compress threads, a new write
+   thread is launched for each input stream.  The write thread writes the
+   appropriate header and trailer around the compressed data.
+
+   The input and output buffers are reused through their collection in pools.
+   Each buffer has a use count, which when decremented to zero returns the
+   buffer to the respective pool.  Each input buffer has up to three parallel
+   uses: as the input for compression, as the data for the check value
+   calculation, and as a dictionary for compression.  Each output buffer has
+   only one use, which is as the output of compression followed serially as
+   data to be written.  The input pool is limited in the number of buffers, so
+   that reading does not get way ahead of compression and eat up memory with
+   more input than can be used.  The limit is approximately two times the
+   number of compression threads.  In the case that reading is fast as compared
+   to compression, that number allows a second set of buffers to be read while
+   the first set of compressions are being performed.  The number of output
+   buffers is not directly limited, but is indirectly limited by the release of
+   input buffers to about the same number.

+/* rsyncable constants -- RSYNCBITS is the number of bits in the mask for
+   comparison.  For random input data, there will be a hit on average every
+   1<<RSYNCBITS bytes.  So for an RSYNCBITS of 12, there will be an average of
+   one hit every 4096 bytes, resulting in a mean block size of 4096.  RSYNCMASK
+   is the resulting bit mask.  RSYNCHIT is what the hash value is compared to
+   after applying the mask.
+
+   The choice of 12 for RSYNCBITS is consistent with the original rsyncable
+   patch for gzip which also uses a 12-bit mask.  This results in a relatively
+   small hit to compression, on the order of 1.5% to 3%.  A mask of 13 bits can
+   be used instead if a hit of less than 1% to the compression is desired, at
+   the expense of more blocks transmitted for rsync updates.  (Your mileage may
+   vary.)
+
+   This implementation of rsyncable uses a different hash algorithm than what
+   the gzip rsyncable patch uses in order to provide better performance in
+   several regards.  The algorithm is simply to shift the hash value left one
+   bit and exclusive-or that with the next byte.  This is masked to the number
+   of hash bits (RSYNCMASK) and compared to all ones except for a zero in the
+   top bit (RSYNCHIT). This rolling hash has a very small window of 19 bytes
+   (RSYNCBITS+7).  The small window provides the benefit of much more rapid
+   resynchronization after a change, than does the 4096-byte window of the gzip
+   rsyncable patch.
+
+   The comparison value is chosen to avoid matching any repeated bytes or short
+   sequences.  The gzip rsyncable patch on the other hand uses a sum and zero
+   for comparison, which results in certain bad behaviors, such as always
+   matching everywhere in a long sequence of zeros.  Such sequences occur
+   frequently in tar files.
+
+   This hash efficiently discards history older than 19 bytes simply by
+   shifting that data past the top of the mask -- no history needs to be
+   retained to undo its impact on the hash value, as is needed for a sum.
+
+   The choice of the comparison value (RSYNCHIT) has the virtue of avoiding
+   extremely short blocks.  The shortest block is five bytes (RSYNCBITS-7) from
+   hit to hit, and is unlikely.  Whereas with the gzip rsyncable algorithm,
+   blocks of one byte are not only possible, but in fact are the most likely
+   block size.
+
+   Thanks and acknowledgement to Kevin Day for his experimentation and insights
+   on rsyncable hash characteristics that led to some of the choices here.

+
+/* Basic thread operations
+
+   This interface isolates the local operating system implementation of threads
+   from the application in order to facilitate platform independent use of
+   threads.  All of the implementation details are deliberately hidden.
+
+   Assuming adequate system resources and proper use, none of these functions
+   can fail.  As a result, any errors encountered will cause an exit() to be
+   executed.
+
+   These functions allow the simple launching and joining of threads, and the
+   locking of objects and synchronization of changes of objects.  The latter is
+   implemented with a single lock type that contains an integer value.  The
+   value can be ignored for simple exclusive access to an object, or the value
+   can be used to signal and wait for changes to an object.
+
+   -- Arguments --
+
+   thread *thread;          identifier for launched thread, used by join
+   void probe(void *);      pointer to function "probe", run when thread starts
+   void *payload;           single argument passed to the probe function
+   lock *lock;              a lock with a value -- used for exclusive access to
+                            an object and to synchronize threads waiting for
+                            changes to an object
+   long val;                value to set lock, increment lock, or wait for
+   int n;                   number of threads joined
+
+   -- Thread functions --
+
+   thread = launch(probe, payload) - launch a thread -- exit via probe() return
+   join(thread) - join a thread and by joining end it, waiting for the thread
+        to exit if it hasn't already -- will free the resources allocated by
+        launch() (don't try to join the same thread more than once)
+   n = join_all() - join all threads launched by launch() that are not joined
+        yet and free the resources allocated by the launches, usually to clean
+        up when the thread processing is done -- join_all() returns an int with
+        the count of the number of threads joined (join_all() should only be
+        called from the main thread, and should only be called after any calls
+        of join() have completed)
+   destruct(thread) - terminate the thread in mid-execution and join it
+        (depending on the implementation, the termination may not be immediate,
+        but may wait for the thread to execute certain thread or file i/o
+        operations)
+
+   -- Lock functions --
+
+   lock = new_lock(val) - create a new lock with initial value val (lock is
+        created in the released state)
+   possess(lock) - acquire exclusive possession of a lock, waiting if necessary
+   twist(lock, [TO | BY], val) - set lock to or increment lock by val, signal
+        all threads waiting on this lock and then release the lock -- must
+        possess the lock before calling (twist releases, so don't do a
+        release() after a twist() on the same lock)
+   wait_for(lock, [TO_BE | NOT_TO_BE | TO_BE_MORE_THAN | TO_BE_LESS_THAN], val)
+        - wait on lock value to be, not to be, be greater than, or be less than
+        val -- must possess the lock before calling, will possess the lock on
+        return but the lock is released while waiting to permit other threads
+        to use twist() to change the value and signal the change (so make sure
+        that the object is in a usable state when waiting)
+   release(lock) - release a possessed lock (do not try to release a lock that
+        the current thread does not possess)
+   val = peek_lock(lock) - return the value of the lock (assumes that lock is
+        already possessed, no possess or release is done by peek_lock())
+   free_lock(lock) - free the resources allocated by new_lock() (application
+        must assure that the lock is released before calling free_lock())
+
+   -- Memory allocation ---
+
+   yarn_mem(better_malloc, better_free) - set the memory allocation and free
+        routines for use by the yarn routines where the supplied routines have
+        the same interface and operation as malloc() and free(), and may be
+        provided in order to supply thread-safe memory allocation routines or
+        for any other reason -- by default malloc() and free() will be used
+
+   -- Error control --
+
+   yarn_prefix - a char pointer to a string that will be the prefix for any
+        error messages that these routines generate before exiting -- if not
+        changed by the application, "yarn" will be used
+   yarn_abort - an external function that will be executed when there is an
+        internal yarn error, due to out of memory or misuse -- this function
+        may exit to abort the application, or if it returns, the yarn error
+        handler will exit (set to NULL by default for no action)

+relink-binaries.sh
+
+Intended to "relink" or change the linker path for a linked binary. Normally
+linked binaries are looking for the linker in /system/bin/linker (or
+/system/bin/linker64 for 64 bit devices). In recovery, we want to avoid
+mounting or using anything /system to allow us to install different
+ROMs or firmware. This script will run various sed commands to update the
+path to the linker to /sbin/linker64 or /sbin/linker which is sometimes
+needed especially for qseecomd (decrypt) or in some cases with user space
+touch screen binaries. Usage:
+
+./relink-binaries.sh filename
+
+The script will leave the existing file untouched and make a new file
+named filename-1-mod
+
+
+
+compare_xml.py
+
+Intended to compare two different language xml files to determine if any
+strings do not match up between the two files. Sometimes we add or rename
+or misspell string names. This script will help identify the discrepancies.
+Usage:
+
+python compare_xml.py -o target.xml
+
+
+
+language_helper.py
+
+This script reads the English and supplied other language files and
+compares the 2 and reorders and rewrites the other language to a new
+XML file such that all the strings are placed in the same order as
+the English file. It will place commented out string lines for items
+that are not present in the new file and will not include any strings
+in the new file that are no longer present in the English source.
+There is also a version tag that may be compared if present between
+the English and other language in case a translation string changes.
