 This software is tested using Google's testing framework *googletest*
 (https://github.com/google/googletest).
 
+The related project `python-cmethods`_ is a Python package that  is implemented
+in Python and is way more flexible in terms of parameters, input data, shapes,
+and customization. For those who know Python at least a bit, this might be the
+better option, as it not only provides a command-line interface but also enables
+accessing its API in order to apply custom bias corrections.
