bug-triage Debian Packages

Thanks to the timely efforts of Loïc Minier, a more usable (even though still featureless) bug-triage version (0.1-2) has found its way to the Debian Archive, alongside with the shining new btsutils 0.2-1. Now it does return something on queries... The development is also progressing, the current version in git can already show the upstream bugs for a given Debian package whose upstream uses bugzilla.
