CVSToys is a collection of companion tools for the Concurrent Versions System, better known as CVS. It currently contains FreshCVS, which performs actions in response to a commit. Actions include notification by various methods, updating a working copy, and rsync'ing to backup. Another key feature of FreshCVS notifications is that you receive one per commit, not one for each directory of the commit as loginfo-triggered scripts are prone to do. FreshCVS is extensible with Python, and notifications may be published by a Perspective Broker network service, allowing 3rd party clients to listen in.
cvscop is a CVS policy program that is launched by the CVS administrative files, commitinfo, loginfo, taginfo, and verifymsg. It can deny CVS actions or launch external scripts based on the configured rule set. Rules can ensure that commit comments follow specified formats, restrict which users can delete tags, and much more.
arch is a modern replacement for CVS, specifically designed for the distributed development needs of open source projects. It has uniquely good support for development on branches (especially good merging tools), distributed repositories (every developer can have branches in their own repository), changeset-oriented project management (arch commits changes to multiple files at once), and, of course, file and directory renaming.
AnthillPro is a build management and lifecycle automation server for the enterprise that makes the build and release process easy and efficient. As a continuous integration server, it can produce a new build for every developer check-in. The entire team can be alerted to problems via email or instant message. Each build can then be promoted to higher statuses, or deployed to various servers and environments using your scripts. At every step, AnthillPro records who did what to keep your auditors happy.
