Support for resolving command-line strings that represent different

Examples:

A factory for objects which provide
L{twisted.cred.checkers.ICredentialsChecker}.
It's implemented by twistd plugins creating checkers.

Return an L{ICredentialChecker} provider using the supplied
argument string.

Defines helper methods that can be added on to any
L{usage.Options} subclass that needs authentication.
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. Default: L{sys.stdout}
