Understanding hobbit

Hello.

There are a few things I dont quite understand yet about hobbit and I cant find anything that explains it in the docs so i better ask :)

In the hobbit "display", the webpage, the hobbit server itself is listed with a few things i dont get on the other servers, like bbd, bbgen, bbtest and hobbitd. These seem to provide interesting things though. I have installed hobbit-client on the clients.
