This mixin implements three new options methods: The opt_auth method (--auth) will write two new values to the 'self' dictionary: C{credInterfaces} (a dict of lists) and C{credCheckers} (a list). The opt_help_auth method (--help-auth) will search for all available checker plugins and list them for the user; it will exit when finished. The opt_help_auth_type method (--help-auth-type) will display detailed help for a particular checker plugin. @cvar supportedInterfaces: An iterable object that returns credential interfaces which this application is able to support. @cvar authOutput: A writeable object to which this options class will send all help-related output.
