Making a better git post-receive Campfire hook. Most of them seem like they were hacked over from old svn hooks--ours certainly is--and they don't handle edge cases and branches well.
To install, run hook.rb from your repository's post-receive hook. The hook
should contain something like this:
while read old_rev new_rev ref; do
ruby hooks/hook.rb $ref $old_rev $new_rev
done
Make sure the post-receive script is executable (otherwise it'll be ignored by
git).
