Internal Program Version: check  0.15.2

Check is a unit test framework for C. It features a simple interface for
defining unit tests, limitating the developer the less possible. Tests
are run in a separate address space, so Check cancatch both, assertion
failures and code errors that cause segmentationfaults or other
signals. The output of unit tests can be used within source code
editors and IDEs.
