;;; Commentary:

;; This package maintains a menu for visiting files that were operated
;; on recently.  When enabled a new "Open Recent" sub menu is
;; displayed in the "Files" menu.  The recent files list is
;; automatically saved across Emacs sessions.  You can customize the
;; number of recent files displayed, the location of the menu and
;; others options (see the source code for details).
