Roundup is a simplistic and highly usable issue-tracking system for command-line, e-mail, and web interfaces. It's easy to use and install and is based on the Ka-Ping Yee design which won the Software Carpentry "Track" competition. The most current stable version is Roundup 1.5.x which comes along with a well-established feature set. You can see the design overview or documentation for more information. Roundup has been previously deployed to assist with:
- bug tracking and TODO list management (the classic installation)
- customer helpdesk support (including a wizard for phone answerers which links to networking, system, and development issue trackers)
- sales lead tracking
- conference paper submission and management of double-blind referees
- issue management for IETF working groups
- weblogging (almost!)
