// In Leopard and earlier, apps that tried to construct a menu bar without a nib would get an undesirable
// stubby application menu that could not be removed. To work around this problem on Leopard, you can call
// the undocumented setAppleMenu: method and pass it the application menu, like so:
// [NSApp setAppleMenu:[[[NSApp mainMenu] itemAtIndex:0] submenu]];
// In SnowLeopard, this workaround is unnecessary and should not be used. Under SnowLeopard, the first menu
// is always identified as the application menu.
