+ * This file is part of mutest, a simple micro unit testing framework for C.

+ * mutest was written by Leandro Lucarella <llucax@gmail.com> and is released
+ * under the BOLA license, please see the LICENSE file or visit:
+ * http://blitiri.com.ar/p/bola/
+ *
+ * This header file should be included in the source files that will make up
+ * a test suite. It's used for both C and Python implementation, but when
+ * using the Python implementation you should define the MUTEST_PY macro.
+ * If you implement your mu_run_suites() function yourself, you probably will
+ * need to include this header too (see mkmutest).
+ *
+ * Please, read the README file for more details.
