collect server config files via rsync and commit them to a CVS with svn

I really like what RANCID does for routers and switches and wanted the same thing for my mail server configs. Here's what I put together with some help from the folks at freenode's #bash IRC channel. I hope someone else can find it a useful starting point. If you have any suggestions on how to improve it, I'd be grateful.
