CUT is a simple, to-the-point unit testing system. It's different from other unit test packages in that it follows the KISS principle. It's designed for C testing, not designed to emulate SUnit.
The currently maintained version of this project is written in Haskell and available in a darcs repository, so Ohloh does not have metrics for it. The new home page is http://www.falvotech.com/content/cut/
