       The  hop  program  generates  real  plane fractals as described in the September 1986 issue of Scientific
       American.

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.

hopalong 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.

       --mono  If on a color display, pretend we're on a monochrome display.

       --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.

       --ncolorsinteger
               How  many  colors  should be used (if possible).  Default 200.  The colors used cycle through the
               hue, making N stops around the color wheel.

       --cyclesinteger
               How long to run each batch.  Default 2500 pixels.

       --countinteger
               How many pixels should be drawn before a color change.  Default 1000.

       --jonginteger--no-jonginteger
               Whether to use the Jong format (default is to choose randomly.)

       --sineinteger--no-sineinteger
               Whether to use the Sine format (default is to choose randomly.)

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