The development of Collaboa has been dormant for a while, but Jason
announced a few days ago on the collaboa mailing list that "the ball is
rolling again". Not at a blazing pace, but fixes are being committed
again and a stable 1.1.6 version seems to be in progress.

I've used collaboa off and on for a while and it's a very nice and well
thought-out piece of software. The only thing that keeps me from using
it right now is that the svn bindings for ruby are a bit of a pain to
get working under OpenBSD (btw: anyone got any hints on how to fix that
under 3.9?).
