If you have it installed on your system (Linux) you can
use the "dialog" command.

If not, you need to use tput to draw, highlight,
blink, revers-video, change colors, etc., using
the terminal capability database "terminfo".

Here are a few demos I wrote awhile back when learning
this stuff, maybe they will help. While suggestions for
improvement are always welcome, please don't laugh!
