# TODO(brettw) Forking out to Python 4 times in serial just to get version
# numbers is highly undesirable. Instead, there should be a build step to
# generate an appropriate header so that the version can be generated at
# build-time, and not at GN-time.

# The |major|, |build| and |patch| versions are inherited from Chrome.
# Since Chrome's |minor| version is always '0', we replace it with a
# Chromoting-specific patch version.
# Note that we check both the |chrome_version_path| file and the
# |remoting_version_path| so that we can override the Chrome version
# numbers if needed.
