 // C++ controller for the bookmark menu; one per AppController (which
 // means there is only one).  When bookmarks are changed, this class
 // takes care of updating Cocoa bookmark menus.  This is not named
 // BookmarkMenuController to help avoid confusion between languages.
 // This class needs to be C++, not ObjC, since it derives from
 // BookmarkModelObserver.
