+        This class provides UDP access to the console to allow remote scripting. The UDP console
+        does support multicast operation.

+        Every UDP packet will be executed in a clean context: No directory groups are open/closed,
+        and the current directory is always the root directory. 
+
+        By default, the server will send command replies via UDP to the sender of the corresponding
+        incoming command. Replies may however either be completely disabled or be sent to a fixed
+        address (which may be a multicast address).
