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.
