DESCRIPTION
       The  hopalong  program  generates  real  plane fractals as
       described in the September 1986 issue of Scientific Ameri-
       can.

OPTIONS
       hopalong accepts the following options:

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

       -root   Draw on the root window.

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

       -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.

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

       -cycles integer
               How  long to run each batch.  Default 2500 pixels.

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

       -jong integer

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

       -sine integer

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

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_MAN-
               AGER property.
