+    for method call messages, where it tells the D-Bus server to
+    either auto start the service responsible for the service name, or
+    not to auto start it.
+
+    By default this flag is true, i.e. a service is autostarted.
+    This means:
+
+    When the service that this method call is sent to is already
+    running, the method call is sent to it. If the service is not
+    running yet, the D-Bus daemon is requested to autostart the
+    service that is assigned to this service name. This is
+    handled by .service files that are placed in a directory known
+    to the D-Bus server. These files then each contain a service
+    name and the path to a program that should be executed when
+    this service name is requested.
