"""Automates building CEF from sources with CEF Python patches applied.

Usage:

automate.py (--prebuilt-cef | --build-cef)

[--force-chromium-update FORCE_CHROMIUM_UPDATE]

[--no-cef-update NO_CEF_UPDATE]

[--cef-branch BRANCH] [--cef-commit COMMIT]

[--build-dir BUILD_DIR] [--cef-build-dir CEF_BUIL_DDIR]

[--ninja-jobs JOBS] [--gyp-generators GENERATORS]

[--gyp-msvs-version MSVS]

automate.py (-h | --help) [type -h to show full description for options]

Options:

-h --help Show this help message.

--prebuilt-cef Whether to use prebuilt CEF binaries. Prebuilt

binaries for Linux are built on Ubuntu.

--build-cef Whether to build CEF from sources with the

cefpython patches applied.

--force-chromium-update Force Chromium update (gclient sync etc).

--no-cef-update Do not update CEF sources (by default both cef/

directories are deleted on every run).

--cef-branch=<b> CEF branch. Defaults to CHROME_VERSION_BUILD from

"src/version/cef_version_{platform}.h".

--cef-commit=<c> CEF revision. Defaults to CEF_COMMIT_HASH from

"src/version/cef_version_{platform}.h".

--build-dir=<dir1> Build directory.

--cef-build-dir=<dir2> CEF build directory. By default same

as --build-dir.

--ninja-jobs=<jobs> How many CEF jobs to run in parallel. To speed up

building set it to number of cores in your CPU.

By default set to cpu_count / 2.

--gyp-generators=<gen> Set GYP_GENERATORS [default: ninja].

--gyp-msvs-version=<v> Set GYP_MSVS_VERSION.
