= The Roundup Bug Tracker = [http://roundup.sourceforge.net/ Roundup] is a highly customizable 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). Instead of Clearsilver or Genshi it uses [http://en.wikipedia.org/wiki/Template%20Attribute%20Language TAL/METAL] (known from Zope) as a template language. In some projects both trac and Roundup are used; Roundup can be customized to support trac-style {{{[wiki:...]}}} links to a trac portal. There's also a [http://www.mechanicalcat.net/tech/roundup/wiki/FrontPage Wiki] for Roundup customization and mailing lists for users and developers.
