DEPS

 # 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').
 #
 # Then commit .DEPS.git locally (gclient doesn't like dirty trees) and run
 #   gclient sync
 # Verify the thing happened you wanted. Then revert your .DEPS.git change
 # DO NOT CHECK IN CHANGES TO .DEPS.git upstream. It will be automatically
 # updated by a bot when you modify this one.
 #
 # When adding a new dependency, please update the top-level .gitignore file
 # to list the dependency's destination directory.
