DESCRIPTION
       This draws a random sequence of colorful barcodes scrolling across your
       screen.

OPTIONS
       --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.

       --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.

       --delay number
               Per-frame delay, in microseconds.  Default: 10000 (0.02
               seconds.).

       --clock Instead of drawing a stream of barcodes, draw a barcode-based
               digital clock.

       --clock24
               Same as --clock, but display 24-hour time instead of 12-hour
               time.

       --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.
