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

SYNOPSIS
       memscroller  [-display  host:display.screen]  [-window] [-root] [-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.

       -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.
