Text positioning/color games

This is actually a huge topic, and almost deserves its own tutorial. But I'm just going to mention it briefly. Some people may be familiar with the "curses" library. It is a way to manipulate and move around text on a screen, reguardless of what kind of "terminal" the user is using.
As mentioned, this is a potentially huge topic. So, I'm just going to give you a trivial example, and say "Go read the man-page on tput". Well, okay, actually, you have to read the "tput" manpage, AND either the "terminfo" or "termcap" manpage to figure out what magical 3-5 letter name to use. For example, it should tell you that "cup" is short for the "cursor_address" command. But you must use "cup", NOT "cursor_address", with tput.

tput init
tput clear
tput cup 3 2
print -n "Here is a clean screen, with these words near the top"
endline=`tput cols`
tput cup $(($endline - 2)) 
print "and now, back to you"
sleep 2
