Hi jaromil

Here is something I knocked up using dialog.
Pretty crude hack, but it may be a starting point for someone better
at it.
You've got to run "dialog create-rc <file>" before it will run.

If the GTK toolkit is available it can be translated into xdialog
with a prettier windowed interface.

Hope it helps those with terminal shyness.
