-# Instructions:
-#
-# To run locally:
-#  (a) Create and change to a directory to run the updater in:
-#      > mkdir /usr/local/google/home/$USER/dartium_deps_updater
-#      > cd /usr/local/google/home/$USER/dartium_deps_updater
-#
-#  (b) Checkout a copy of the DEPS for the updater to process / update:
-#      > svn co https://dart.googlecode.com/svn/branches/bleeding_edge/deps/dartium.deps
-#
-#  (c) Checkout dartium_tools (with this script) using the current branch instead of 1750:
-#      > svn co svn://svn.chromium.org/chrome/branches/dart/1750/src/dartium_tools
-#
-#  (d) If your home directory is remote, consider redefining it for this shell/script:
-#      > cp -R $HOME/.subversion /usr/local/google/home/$USER
-#      > export HOME=/usr/local/google/home/$USER
-#
-#  (e) Test by running (Ctrl-C to quit):
-#      > ./dartium_tools/update_deps.py
-#
-#  (f) Run periodical update:
-#      > while true; do ./dartium_tools/update_deps.py --force ; sleep 300 ; done

-# Each element in this map represents a repository to update.  Entries
-# take the form:
-#  (repo_tag: (svn_url, view_url))
-#
-# The repo_tag must match the DEPS revision entry.  I.e, there must be
-# an entry of the form:
-#   'dartium_%s_revision' % repo_tag
-# to roll forward.
-#
-# The view_url should be parameterized by revision number.  This is
-# used to generated the commit message.
