ViewVC (formerly known as ViewCVS) is a Python/CGI-based system for viewing and interacting with Subversion and CVS repositories through your Web browser. It can browse directories, view changelogs, generate diffs, view arbitrary revisions, and display annotated ("blame") listings. It has full support for tags and branches, and contains a database-backed query system like Bonsai. It was initially based on the cvsweb work by Henner Zeller, but has been ported to Python and dramatically enhanced.
JumpBox for Redmine is a virtual machine with a pre-installed instance of Redmine, a project management and issue tracking system for software developers. Redmine provides many of the features in Trac plus support for multiple projects, role based access control, time tracking functionality, Gantt charts, a calendar view, and user self-registration. It includes tight integration with Subversion, and the JumpBox includes everything you need.
