AND IT"S AWESOME!
I really like being able to email "everything" to myself as a single file. Where "everything" means "all the source, all the revision history, all the wiki documentation, all the bug reports". I really like that it can operate both server/client like CVS and Subversion, and also push/pull/sync like git. I really like that it's easy to compile and install. I haven't played with editing the HTML or CSS of the header and footer, but the defaults are tasteful, and I like that the option is available and pretty easy to use.
