NAME
       hopalong - draw real plane fractals

SYNOPSIS
       hopalong	  [-display   host:display.screen]   [-foreground
       color]  [-background  color]  [-window]	[-root]	  [-mono]
       [-install]  [-visual  visual]  [-ncolors	 integer] [-delay
       microseconds] [-cycles integer] [-count	integer]  [-jong]
       [-no-jong] [-jong] [-no-sine]

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

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.
