 A :class:`ServerProxy` instance has a method corresponding to each remote
 procedure call accepted by the XML-RPC server.  Calling the method performs an
 RPC, dispatched by both name and argument signature (e.g. the same method name

 Servers that support the XML introspection API support some common methods
 grouped under the reserved :attr:`~ServerProxy.system` attribute:
