-// 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.
-// The presented view controller (that is, the view controller that runs the
-// menu) should set the size of its view in -loadView or -viewDidLoad.
-// If the presenting view controller conforms to the MenuPresentationDelegate
-// protocol, that protocol will be used to determine the region the menu
-// appears in; otherwise it will appear in the center of the presenting view
-// the region the menu appears in. Otherwise a default rectangular area is
-// controller's view.
-@interface MenuPresentationController : UIPresentationController
-// The dispatcher for this presentation controller.
