Getting notified about git commits pushed to a project

[Martin Nordholts <enselic gmail com>]

Hi

What options do I have for getting notified about commits to GNOME git 
modules?

I would like to set up buildbot for GIMP. My plan is to have nightly 
builds, hopefully eventually building binaries for all platforms. I 
would also like to do automated testing for each new commit, but I need 
some way for buildbot to get notified about commits then.

Is it possible to install hooks on the GNOME git server? Is it possible 
to setup mails being sent when a commit happens? IIRC there is such list 
already, does it exist on a per-git-module basis too?

Thanks in advance for any input

Regards,
Martin
