+* Author:     Brad Conte (brad AT bradconte.com)

+* Disclaimer: This code is presented "as is" without any guarantees.
+* Details:    Performs known-answer tests on the corresponding MD2
+	          implementation. These tests do not encompass the full
+	          range of available test vectors, however, if the tests
+	          pass it is very, very likely that the code is correct
+	          and was compiled properly. This code also serves as
+	          example usage of the functions.
