556 // Use the following extra files:
557 //
558 // init.el:
559 // ;; Hide menu and place frame slightly above the top of the screen.
560 // (setq ns-auto-hide-menu-bar t)
561 // (set-frame-position (selected-frame) 0 -20)
562 //
563 // Test 1:
564 //
565 // emacs -Q -l init.el
566 //
567 // Result: No menu bar, and the title bar should be above the screen.
568 //
569 // Test 2:
570 //
571 // emacs -Q
572 //
573 // Result: Menu bar visible, frame placed immediately below the menu.
