.SH DESCRIPTION
The \fIifs\fP program draws spinning, colliding iterated-function-system images.
.SH OPTIONS
-.I ifs
-accepts the following options:
+.TP 8
+.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 \-window
Draw on a newly-created window. This is the default.
.B \-root
Draw on the root window.
.TP 8
-.B \-mono
-If on a color display, pretend we're on a monochrome display.
+.B \-no\-db
+Disable double-buffering.
.TP 8
-.B \-install
-Install a private colormap for the window.
+.B \-delay \fInumber\fP
+Per-frame delay, in microseconds. Default: 20000
.TP 8
-.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.
+.B \-colors \fInumber\fP
+Number of colours to use. Default: 200
+.TP 8
+.B \-detail \fInumber\fP
+In \fI\-iterate\fP mode, number of times to randomly iterate the
+functions, in thousands. In \fI\-recurse\fP mode, number of times
+to apply functions (recursion depth) before drawing each point.
+Default: 9
.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.
+.B \-functions \fInumber\fP
+Number of functions to be iterated. Default: 3
+.TP 8
+.B \-iterate
+Calculate by iteratively applying the functions in a random order,
+usually faster than \fI\-recurse\fP. This is the default.
+.TP 8
+.B \-recurse
+Calculate by recursively applying all combinations of the functions.
+This is the historical behavior and may produce neater output than
+\fI\-iterate\fP.
+.TP 8
+.B \-no-rotate
+Disable the rotation component of the functions.
+.TP 8
+.B \-no-scale
+Disable the scaling component of the functions.
+.TP 8
+.B \-no-translate
+Disable the varying translation component of the functions.
+.TP 8
+.B \-no-multi
+Turn off multi-coloured mode, only one colour is used to colour the whole set.
