+	help
+	  cmocka is an elegant unit testing framework for C with support
+	  for mock objects. It only requires the standard C library,
+	  works on a range of computing platforms (including embedded)
+	  and with different compilers. It is a fork of Google's very
+	  popular cmockery unit testing framework to fix bugs and
+	  support it in the future.
