+// A SVMenuNode is an entity which contains the mapping from a menu entry on
+// the server side to the corresponding associated commands on the client.
+// It is designed to be a tree structure with a root node, which can then be
+// used to generate the appropriate messages to the server to display the
+// menu structure there.
+// A SVMenuNode can both be used in the context_ of popup menus as well as
+// menu bars.
