CUT is designed to aid the C (or C-derived language) programmer in implementing unit or programmer tests, primarily to facilitate test-driven development practices.
CUT was primarily written by myself and by Billy Tanksley, starting life as distinct, and even competing, CUT 1.0 and test-assert packages. When it was finally decided to combine both packages into a single tool, CUT 2.0 was released, and found to be vastly more useful than either expected. CUT 2.4 is the latest version of the CUT 2.x series.
You can get the latest stable release 2.4 here.
Alternatively, if you use darcs, you can obtain the latest builds this way:
Code or documentation contributions are of course always welcome.
