Chromium Updater
http://benalman.com/

Usage: $(basename "$0") [revision]

Download and install the latest Chromium and dev tools, modifying the binary
to use those custom dev tools (downloaded into ~/.dotfiles/caches/chromium).
See ~.dotfiles/conf/update_chromium_etc.sh for sample dev tools customization.

If a revision isn't specified, the latest stable revision will be installed.
