I should have added a few more things to this...
* The UCB version was HBotSVN, but I wouldn't recommend adding that to the
description of it.  (Actually, the UCB simply represents the configuration
for the tournament)
* The old entries for the various flavors of HouseBot were left on the bot
names page.  While I would recommend deleting those old entries, I'd
appreciate it if you kept the link to the homepage:
