	11	The wxFileHistory encapsulates a user interface convenience, the list of
	12	most recently visited files as shown on a menu (usually the File menu).
	13
	14	wxFileHistory can manage one or more file menus. More than one menu may be
	15	required in an MDI application, where the file history should appear on
	16	each MDI child menu as well as the MDI parent frame.
