""" See automate.py. This script is for internal usage only, don't
call it directly. This is a modified copy of automate-git.py from
upstream CEF.

Some modifications were applied for CEF Python specific use case.
There is a patch file with the same name as this script that contains
differences from the original file.

--------

Usage: automate-git.py [options]

 This utility implements automation for the download, update, build and
distribution of CEF.

Options:
  -h, --help            show this help message and exit
  --download-dir=DIR    Download directory with no spaces [required].
  --depot-tools-dir=DIR
                        Download directory for depot_tools.
  --depot-tools-archive=DEPOTTOOLSARCHIVE
                        Zip archive file that contains a single top-level
                        depot_tools directory.
  --branch=BRANCH       Branch of CEF to build (trunk, 1916, ...). This will
                        be used to name the CEF download directory and to
                        identify the correct URL if --url is not specified.
                        The default value is trunk.
  --url=URL             CEF download URL. If not specified the default URL
                        will be used.
  --chromium-url=CHROMIUMURL
                        Chromium download URL. If not specified the default
                        URL will be used.
  --checkout=CHECKOUT   Version of CEF to checkout. If not specified the most
                        recent remote version of the branch will be used.
  --chromium-checkout=CHROMIUMCHECKOUT
                        Version of Chromium to checkout (Git branch/hash/tag).
                        This overrides the value specified by CEF in
                        CHROMIUM_BUILD_COMPATIBILITY.txt.
  --force-config        Force creation of a new gclient config file.
  --force-clean         Force a clean checkout of Chromium and CEF. This will
                        trigger a new update, build and distribution.
  --force-clean-deps    Force a clean checkout of Chromium dependencies. Used
                        in combination with --force-clean.
  --dry-run             Output commands without executing them.
  --dry-run-platform=DRYRUNPLATFORM
                        Simulate a dry run on the specified platform (windows,
                        macosx, linux). Must be used in combination with the
                        --dry-run flag.
  --force-update        Force a Chromium and CEF update. This will trigger a
                        new build and distribution.
  --no-update           Do not update Chromium or CEF. Pass --force-build or
                        --force-distrib if you desire a new build or
                        distribution.
  --no-cef-update       Do not update CEF. Pass --force-build or --force-
                        distrib if you desire a new build or distribution.
  --no-chromium-update  Do not update Chromium.
  --no-depot-tools-update
                        Do not update depot_tools.
  --force-build         Force CEF debug and release builds. This builds
                        [build-target] on all platforms and chrome_sandbox on
                        Linux.
  --no-build            Do not build CEF.
  --build-target=BUILDTARGET
                        Target name(s) to build (defaults to "cefclient").
  --build-tests         Also build the cef_unittests target.
  --no-debug-build      Don't perform the CEF debug build.
  --no-release-build    Don't perform the CEF release build.
  --verbose-build       Show all command lines while building.
  --build-log-file      Write build logs to file. The file will be named
                        "build-[branch]-[debug|release].log" in the download
                        directory.
  --x64-build           Build for 64-bit systems (Windows and Mac OS X only).
  --force-distrib       Force creation of a CEF binary distribution.
  --no-distrib          Don't create a CEF binary distribution.
  --minimal-distrib     Create a minimal CEF binary distribution.
  --minimal-distrib-only
                        Create a minimal CEF binary distribution only.
  --client-distrib      Create a client CEF binary distribution.
  --client-distrib-only
                        Create a client CEF binary distribution only.
  --no-distrib-docs     Don't create CEF documentation.
  --no-distrib-archive  Don't create archives for output directories.
  --clean-artifacts     Clean the artifacts output directory.
  --distrib-subdir=DISTRIBSUBDIR
                        CEF distrib dir name, child of
                        chromium/src/cef/binary_distrib
