Looking for menu engine

[Marcel Krause]

Dear list,

I'm writing some script and want to replace its command line with a
menu for enhanced compatibility with modern computer users. I found
"pdmenu" and it is very nice, except that it can't display colons in
its menu titles, so I cannot make my options menu in the
"option: current value" style. This is because its menu description
language uses the colon to separate the commands and their parameters.

Do you know another cool menu engine? Is the one that lers me pick
my language in the Ubuntu Installer easy to use? I'd like to give
the menu engine a text file with the menu items and then it runs an
application associated with the selected item.

Bonus if I can make it exit when running the app, like using the exec()
syscall. (RAM is critical on some of the target devices.)

Extra bonus if instead of running an app it quits with an exit code
that identifies the selected item.

Ciao, Marcel
