If you face problems when using casu or if you find it difficult to understand the code, please send me an email to It might take me a few minutes, what costs you some days. The software is documented inside the code. The explanations where clear to me, but need not be enlightening to you as well. Your questions will help to improve the documentation. If you did calculations with casu, think about adding them to the test cases section. Jens Wyrwa
