Dnspython modules may also define their own exceptions, which will
always be subclasses of ``DNSException``.

�Z� xZS ) � 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 the standard Python Exception class as before and all *args* are
printed by the 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* must be empty and all kwargs must match
those set in class variable ``supp_kwargs``. All kwargs are stored inside
``self.kwargs`` and used in a new ``__str__`` implementation to construct
a formatted message based on the ``fmt`` class variable, a ``string``.
In the simplest case it is enough to override the ``supp_kwargs``
and ``fmt`` class variables to get nice parametrized messages.
