Commitomatic is an experiment. It watches your git repos for changes and reports them. Waiting for you to hook in some action. Ofcourse you could use git's own hooks, but that requires you to set it up per project.
Code isn't optimized, or pretty for that matter :).
$ sudo gem install grit
FSSM might tell you to install additional platform specific gems.
Simply append the path to your repos and watch.
$ ruby watch.rb /home/git/repositores
