It supports two basic modes of operation: a) Old/compatible mode is used if __init__ was called with empty **kwargs. In compatible mode all *args are passed to standard Python Exception class as before and all *args are printed by standard __str__ implementation. Class variable msg (or doc string if msg is None) is returned from str() if *args is empty. b) New/parametrized mode is used if __init__ was called with non-empty **kwargs. In the new mode *args has to be empty and all kwargs has to exactly match set in class variable self.supp_kwargs. All kwargs are stored inside self.kwargs and used in new __str__ implementation to construct formatted message based on self.fmt string. In the simplest case it is enough to override supp_kwargs and fmt class variables to get nice parametrized messages.
