DEPS

 # This DEPS file checks out a read-only copy of the Chromium buildbot code at
 # a revision that is known to work with the current Skia buildbot setup.
 #
 # Thus, this DEPS file is useful for:
 #  - users who just want to run, not modify, the Skia buildbot
 #  - developers who wish to make changes to the Skia buildbot config but NOT
 #    the underlying Chromium buildbot code
 #
 # To check out the Skia buildbot code using this DEPS file, run:
 #  gclient config https://skia.googlesource.com/buildbot.git
 #  gclient sync
