.SH DESCRIPTION
The \fIhop\fP program generates real plane fractals as described in
the September 1986 issue of Scientific American.
.SH OPTIONS

accepts the following options:
.TP 8
.B \-\-window
Draw on a newly-created window.  This is the default.
.TP 8
.B \-\-root
Draw on the root window.
.TP 8
.B \-\-window\-id \fInumber\fP
Draw on the specified window.
.TP 8
.B \-\-mono 
If on a color display, pretend we're on a monochrome display.
.TP 8
.B \-\-install
Install a private colormap for the window.

.B \-\-visual \fIvisual\fP
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.
.TP 8
.B \-\-ncolors \fIinteger\fP
How many colors should be used (if possible).  Default 200.
The colors used cycle through the hue, making N stops around
the color wheel.
.TP 8
.B \-\-cycles \fIinteger\fP
How long to run each batch.  Default 2500 pixels.
.TP 8
.B \-\-count \fIinteger\fP
How many pixels should be drawn before a color change.  Default 1000.
.TP 8
.B \-\-jong \fIinteger\fP
.TP 8
.B \-\-no\-jong \fIinteger\fP
Whether to use the Jong format (default is to choose randomly.)

.TP 8
.B \-\-sine \fIinteger\fP
.TP 8
.B \-\-no\-sine \fIinteger\fP
Whether to use the Sine format (default is to choose randomly.)

.TP 8
.B \-\-fps
Display the current frame rate and CPU load.
.SH ENVIRONMENT
.PP
.TP 8
.B DISPLAY
to get the default host and display number.
.TP 8
.B XENVIRONMENT
to get the name of a resource file that overrides the global resources
stored in the RESOURCE_MANAGER property.
.TP 8
.B XSCREENSAVER_WINDOW
