The menu is implemented as a series of 4th modules. Here's an earlier version
of the code which I've been using on my LiveDistro boot disc:

I think you'll like the Forth code that I've written. I strived to keep it
clean and modular. IMHO I feel that it's really easy to change/enhance/extend
based on the menu mechanics as seen in "menu.rc", and
"include/menu-commands.4th".
