 The \fIifs\fP program draws spinning, colliding iterated-function-system images.

 .B \-root
 Draw on the root window.

-.B \-delay \fInumber\fP
-Per-frame delay, in microseconds.  Default: 10000
+.B \-no\-db
+Disable double-buffering.
 .TP 8
-.B \-mode \fImode\fP
-Colouring mode. 0 = blend, 1 = per-function, 2 = single colour.  Default: 0

+Per-frame delay, in microseconds.  Default: 20000

 .B \-colors \fInumber\fP
 Number of colours to use. Default: 200
 .TP 8
 .B \-detail \fInumber\fP
-Number of times to iterate each function. Default: 9
+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 \-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.

+.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.
