[Qemu-devel] [PATCH] Machine menu patch for Mac OS X

[Programmingkid]

This patch adds a Machine menu to QEMU. This menu gives the user the ability to 
easily work with floppy and CD image files.

Features:
Menu items to switch floppy and CD image files.
Menu items to eject floppy and CD image files.
Menu item to use /dev/cdrom. 
Verifies with the user before quitting QEMU by displaying a dialog box.
