+// A presentation controller for presenting a "menu" interface: a (usually)
+// rectangular presentation that covers part of the window, and which doesn't
+// obscure the presenting view. The presenting view remains in the view
+// hierarchy. If the presenting view controller confroms to the
+// MenuPresentationDelegate protocol, that protocol will be used to determine
+// the region the menu appears in. Otherwise a default rectangular area is
+// used.
