-# 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) Make a 'deps' directory to store temporary files:
-#      > mkdir deps
-#
-#  (c) Checkout dart/tools/dartium (with this script):
-#      > svn co https://dart.googlecode.com/svn/branches/bleeding_edge/dart/tools/dartium 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
-#      > ./dartium_tools/update_deps.py --target=clank
-#      > ./dartium_tools/update_deps.py --target=integration
-#
-#  (f) Run periodical update:
-#      > while true; do ./dartium_tools/update_deps.py --force ; sleep 300 ; done
