DESCRIPTION

13       This screen saver is not meant to look pretty, but  rather,  to  repair
14       burn-in on LCD monitors.
15
16       Believe it or not, screen burn is not a thing of the past.  It can hap‐
17       pen to LCD screens pretty easily, even in this  modern  age.   However,
18       leaving the screen on and displaying high contrast images can often re‐
19       pair the damage.  That's what this screen saver does.
