trac setup docu to feed tor-bugs ML

Hi,

I'd like to know how you configured your trac so that every update goes as an email to https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-bugs

I haven't seen such a feature on http://trac.edgewall.org/wiki/TracNotification

Did you made custom changes to trac? Is there documentation about your setup somewhere?

thanks!
