Ú DNSExceptiona¡ Abstract base class shared by all dnspython exceptions.
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.
