Hi Frederic!,

good points all of them! I comment below.

Yes, I think making it optional is ok. BTW, another option, I think
Thomas mentioned it some time ago, would be that slaves would send the
coverage reports to the master, which would be the only one running a

The per-module approach is a very good idea, if that works reasonably
well then we could think about IRC notifications seriously.

Actually this is very interesting feature imho, it is a pain to do it
manually, although now it is not as annoying as it was before.

I guess you mean a web interface to do this kind of maintenance tasks.
That would be good to have, sure.

Yeah, this would be interesting although I guess this would not be so
easy to implement (just guessing).

I'll add a couple of extra points:

Implement the jhbuild bot stop command (I'll check this myself) . Also,
it would be nice if we could store the logs in a file, right now I think
they are sent to stdout directly. And also, it would be nice to have a
way to automatically clean old logs (from twisted and buildbot).
