+    """Check is a unit testing framework for C. It features a simple interface
+    for defining unit tests, putting little in the way of the developer. Tests
+    are run in a separate address space, so both assertion failures and code
+    errors that cause segmentation faults or other signals can be caught. Test
+    results are reportable in the following: Subunit, TAP, XML, and a generic
+    logging format."""
