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

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.

memscroller accepts the following options:

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

       --root  Draw on the root window.

       --window-idnumber
               Draw on the specified window.

       --install
               Install a private colormap for the window.

       --visualvisual
               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.

       --filenamefile
               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 display
               anything, because it returns EOF without ever returning any data.)

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

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