NAME
       lcdscrub	- attempt to repair burn-in on LCD screens

SYNOPSIS
       lcdscrub	 [-display  host:display.screen]  [-visual  visual]  [-window]
       [-root] [-delay number] [-spread	number]	[-cycles number] [-fps]

DESCRIPTION
       This screen saver is not	meant to look pretty, but  rather,  to	repair
       burn-in on LCD monitors.

       Believe it or not, screen burn is not a thing of	the past.  It can hap-
       pen to LCD screens pretty easily, even in this  modern  age.   However,
       leaving the screen on and displaying high contrast images can often re-
       pair the	damage.	 That's	what this screen saver does.
