 """Call a D-BUS method and wait for its reply. This method calls the D-BUS method with name *method* that resides on the object at bus address *service*, at path *path*, on interface *interface*. The *signature* and *args* are optional arguments that can be used to add parameters to the method call. The signature is a D-BUS signature string, while *args* must be a sequence of python types that can be converted into the types specified by the signature. See the `D-BUS specification <http://dbus.freedesktop.org/doc/dbus-specification.html>`_ for a reference on signature strings. The flags *no_reply* and *auto_start* control the NO_REPLY_EXPECTED and NO_AUTO_START flags on the D-BUS message. The return value is the result of the D-BUS method call. This will be a possibly empty sequence of values. """
