+// An example of using Fl_Menu_Bar's add() to dynamically create menubars
+//
+// Menu bars can be created several ways. Using add() allows
+// dynamically creating a menubar using a 'pathname' syntax.
+// Use if you're creating items dynamically, or if you're making
+// menubars by hand (as opposed to using fluid), as it's easier
+// to type and read.
+//
+// In this case we're using one callback for all items,
+// but you can make unique callbacks for each item if needed.
