After debconf5 arriving I couldn't sleep very well, so I woke up really early and I wrote a cool macro for Trac environment that you can see here.
Anyway, some examples of usage:
Giving a maintainer mail address: [[debianBTS(tiago@debian-ba.org)]] Giving a bug number: [[debianBTS(311091)]] Giving a package name: [[debianBTS(bbclone)]]
