Exceptions and Warnings
=======================

Exceptions
----------

Errors derive from Exception or another custom error. Custom errors are
only needed if standard errors, for example ValueError or TypeError, are not
accurate descriptions of the cause for the error.

   ParseError
   PerfectSeparationError
   X13NotFoundError
   X13Error

Warnings
--------

Warnings derive from either an existing warning or another custom
warning, and are often accompanied by a string using the format
``warning_name_doc`` that services as a generic message to use when the
warning is raised.
