116 * /cache/recovery/intent - OUTPUT - intent that was passed in
117 *
118 * The arguments which may be supplied in the recovery.command file:
119 * --send_intent=anystring - write the text out to recovery.intent

139 * -- after this, rebooting will restart the main system --
140 * 8. main() calls reboot() to boot main system
141 *
142 * OTA INSTALL

148 * 5. install_package() attempts to install the update
149 * NOTE: the package install must itself be restartable from any point
150 * 6. finish_recovery() erases BCB
151 * -- after this, rebooting will (try to) restart the main system --
152 * 7. ** if install failed **
153 * 7a. prompt_and_wait() shows an error icon and waits for the user
154 * 7b; the user reboots (pulling the battery, etc) into the main system
155 * 8. main() calls maybe_install_firmware_update()
156 * ** if the update contained radio/hboot firmware **:
157 * 8a. m_i_f_u() writes BCB with "boot-recovery" and "--wipe_cache"
158 * -- after this, rebooting will reformat cache & restart main system --
159 * 8b. m_i_f_u() writes firmware image into raw cache partition

162 * 8d. bootloader tries to flash firmware
