Given a target-files zipfile, produces an OTA package that installs
that build.  An incremental OTA is produced if -i is given, otherwise
a full OTA is produced.

Usage:  ota_from_target_files [flags] input_target_files output_ota_package

  -b  (--board_config)  <file>
      Deprecated.

  -k (--package_key) <key> Key to use to sign the package (default is
      the value of default_system_dev_certificate from the input
      target-files's META/misc_info.txt, or
      "build/target/product/security/testkey" if that value is not
      specified).

      For incremental OTAs, the default value is based on the source
      target-file, not the target build.

  -i  (--incremental_from)  <file>
      Generate an incremental OTA using the given target-files zip as
      the starting build.

  -w  (--wipe_user_data)
      Generate an OTA package that will wipe the user data partition
      when installed.

  -n  (--no_prereq)
      Omit the timestamp prereq check normally included at the top of
      the build scripts (used for developer OTA packages which
      legitimately need to go back and forth).

  -e  (--extra_script)  <file>
      Insert the contents of file at the end of the update script.

  -a  (--aslr_mode)  <on|off>
      Specify whether to turn on ASLR for the package (on by default).

  --backup <boolean>
      Enable or disable the execution of backuptool.sh.
      Disabled by default.

  --override_device <device>
      Override device-specific asserts. Can be a comma-separated list.

  -p  (--path)  <dir>
      Prepend <dir>/bin to the list of places to search for binaries
      run by this script, and expect to find jars in <dir>/framework.

  -s  (--device_specific) <file>
      Path to the python module containing device-specific
      releasetools code.

  -x  (--extra)  <key=value>
      Add a key/value pair to the 'extras' dict, which device-specific
      extension code may look at.

  -v  (--verbose)
      Show command lines being executed.

  -h  (--help)
      Display this usage message and exit.
