The Roundup Bug Tracker

​Roundup is a Bug Tracker (and more…) written in Python.

It is somewhat older than Trac and some people think it's more mature in some areas (like E-Mail integration).

There's also a ​Wiki for discussing Roundup (which seems to be not very active).

The ​issues in the tabulator project is a RoundUp installation; what would it take to migrate it to Trac? ​Dan Connolly is interested to know.
