NAME
       memscroller - scrolls a dump of its own RAM across the screen

SYNOPSIS
       memscroller [--display host:display.screen] [--window] [--root] [--win-
       dow-id  number][--mono]	[--install]  [--visual	visual]	 [--font font]
       [--delay	int] [--mono | -color] [--ram |	 -random  |  --filename	 file]
       [--fps]

DESCRIPTION
       The memscroller program scrolls a dump of its own process memory	across
       the screen in three windows at three different rates.

OPTIONS
       memscroller accepts the following options:

       --window
	       Draw on a newly-created window.	This is	the default.

       --root  Draw on the root	window.

       --window-id number
	       Draw on the specified window.

       --install
	       Install a private colormap for the window.

       --visual	visual
	       Specify	which  visual  to use.	Legal values are the name of a
	       visual class, or	the id number (decimal or hex) of  a  specific
	       visual.

       --color Render  each three bytes	of memory as R,	G, B.  This is the de-
	       fault.

       --mono  Render each byte	of memory in shades of green.

       --ram   Read from the process's address space.  This is the default.

       --random
	       Instead of reading from memory, generate	random numbers.

       --filename file
	       Instead of reading from memory, read from the given file	 until
	       EOF,  then  re-open it.	If you have permission,	/dev/mem is an
	       interesting choice here.	 (Note that /dev/null won't ever  dis-
	       play  anything,	because	 it returns EOF	without	ever returning
	       any data.)

       --delay microseconds
	       How much	of a delay should be introduced	between	steps  of  the
	       animation.  Default 10000.

       --fps   Display the current frame rate and CPU load.

ENVIRONMENT
       DISPLAY to get the default host and display number.

       XENVIRONMENT
	       to  get	the  name of a resource	file that overrides the	global
	       resources stored	in the RESOURCE_MANAGER	property.

       XSCREENSAVER_WINDOW
	       The window ID to	use with --root.
