Cerberus is a Continuous Integration software for Ruby projects. CI helps you keep your project in a good shape. For now Cerberus only work with projects that use Subversion but in the future it would be provided support for other VCS. Cerberus could be easily invoked from Cron (for Unix) or nnCron (for Windows) utilities.
