 # This file is automatically processed to create .DEPS.git which is the file
 # that gclient uses under git.

 # See http://code.google.com/p/chromium/wiki/UsingGit

 # To test manually, run:
 #   python tools/deps2git/deps2git.py -o .DEPS.git -w <gclientdir>
 # where <gcliendir> is the absolute path to the directory containing the
 # .gclient file (the parent of 'src').
