+# *4: Only do this for the relevant bits. On a 64 bits system, leave the 32 bits files alone, or dynamic linker errors

+#
+# It may seem some files are installed multiple times needlessly, but
+# it only seems that way. Installing files differently or symlinking
+# instead of copying (unless specified) will lead to issues eventually.
+#
+# The following su binary versions are included in the full package. Each
+# should be installed only if the system has the same or newer API level 
+# as listed. The script may fall back to a different binary on older API
+# levels. supolicy are all ndk/pie/19+ for 32 bit, ndk/pie/20+ for 64 bit.
+#
+# binary        ARCH/path   build type      API
+#
+# arm-v5te      arm         aosp static     7+
+# x86           x86         aosp static     7+
+#
+# arm-v7a       armv7       ndk pie         17+
+# mips          mips        ndk pie         17+

+#
+# Note that if SELinux is set to enforcing, the daemonsu binary expects 
+# to be run at startup (usually from install-recovery.sh, 99SuperSUDaemon,
+# or app_process) from u:r:init:s0 or u:r:kernel:s0 contexts. Depending
+# on the current policies, it can also deal with u:r:init_shell:s0 and
+# u:r:toolbox:s0 contexts. Any other context will lead to issues eventually.
+#
+# After installation, run '/system/xbin/su --install', which may need to
+# perform some additional installation steps. Ideally, at one point,
+# a lot of this script will be moved there.
+#
+# The included chattr(.pie) binaries are used to remove ext2's immutable
+# flag on some files. This flag is no longer set by SuperSU's OTA
+# survival since API level 18, so there is no need for the 64 bit versions.
+# Note that chattr does not need to be installed to the system, it's just
+# used by this script, and not supported by the busybox used in older
+# recoveries.
+#
+# Non-static binaries are supported to be PIE (Position Independent 
+# Executable) from API level 16, and required from API level 20 (which will
+# refuse to execute non-static non-PIE). 
+#
+# The script performs serveral actions in various ways, sometimes
+# multiple times, due to different recoveries and firmwares behaving
+# differently, and it thus being required for the correct result.
