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 default.

     --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  interest-
	     ing choice here.  (Note that /dev/null won't ever display anything,
	     because it returns EOF without ever returning any data.)

     --delay microseconds
	     How  much of a delay should be introduced between steps of the ani-
	     mation.  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  re-
	     sources stored in the RESOURCE_MANAGER property.

     XSCREENSAVER_WINDOW
	     The window ID to use with --root.
