-# This file is automatically processed to create .DEPS.git which is the file
-# that gclient uses under git.
+# This file is used to manage the dependencies of the Chromium src repo. It is
+# used by gclient to determine what version of each dependency to check out, and
+# where.
#
-# 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.

+# # Create and switch to a new branch
+# git new-branch depsroll
+# # Run roll-dep (provided by depot_tools) giving the dep's path and the
+# # desired SVN revision number (e.g., third_party/foo/bar and a revision such
+# # number from Subversion)
