This plugin installs a DEPRECATED error class for the :class:`DeprecatedTest`
exception. When :class:`DeprecatedTest` is raised, the exception will be logged
in the deprecated attribute of the result, ``D`` or ``DEPRECATED`` (verbose)
will be output, and the exception will not be counted as an error or failure.
It is enabled by default, but can be turned off by using ``--no-deprecated``.
