  Usage: $PROGNAME [options]

  This script is used to check that your Google Breakpad source tree can
  be properly built for Android, and that the client library and host tools
  work properly together.
"
  if [ "$HELP_ALL" ]; then
    echo "\
  In more details, this script will:

  - Rebuild the host version of Google Breakpad in a temporary
    directory (with the Auto-tools based build system).

  - Rebuild the Android client library with the Google Breakpad build
    system (using autotools/configure). This requires that you define
    ANDROID_NDK_ROOT in your environment to point to a valid Android NDK
    installation directory, or use the --ndk-dir=<path> option.

  - Rebuild the Android client library and a test crashing program with the
    Android NDK build system (ndk-build).

  - Require an Android device connected to your machine, and the 'adb'
    tool in your path. They are used to:

      - Install and  run a test crashing program.
      - Extract the corresponding minidump from the device.
      - Dump the symbols from the test program on the host with 'dump_syms'
      - Generate a stack trace with 'minidump_stackwalk'
      - Check the stack trace content for valid source file locations.

    You can however skip this requirement and only test the builds by using
    the --no-device flag.

    By default, all generated files will be created in a temporary directory
    that is removed when the script completion. If you want to inspect the
    files, use the --no-cleanup option.

    Finally, use --verbose to increase the verbosity level, this will help
    you see which exact commands are being issues and their result. Use the
    flag twice for even more output. Use --quiet to decrease verbosity
    instead and run the script silently.

    If you have a device connected, the script will probe it to determine
    its primary CPU ABI, and build the test program for it. You can however
    use the --abi=<name> option to override this (this can be useful to check
    the secondary ABI, e.g. using --abi=armeabi to check that such a program
    works correctly on an ARMv7-A device).

    If you don't have a device connected, the test program will be built (but
    not run) with the default '$DEFAULT_ABI' ABI. Again, you can use
    --abi=<name> to override this. Valid ABI names are:

        $VALID_ABIS

    The script will only run the client library unit test on the device
    by default. You can use --all-tests to also build and run the unit
    tests for the Breakpad tools and processor, but be warned that this
    adds several minutes of testing time. --all-tests will also run the
    host unit tests suite.
