Veto is a test management tool that allows you to run the relevant tests, all the relevant tests, and nothing but the relevant tests. Veto is designed to work in projects maintained by some version control systems such as CVS. Veto makes use of a build tool such as make to automate running all/new/changed/relevant tests, and makes it easy to integrate this into the normal build procedure of the project.

Veto is hosted at SourceForge. You can also download the tarball here.
