.SH DESCRIPTION
The \fIgflux\fP program draws a colourfull animated rippling square rotating in 3D space.
.SH OPTIONS
.TP 8
.B \-zoom \fInum\fP\fP
Specifies the size of the viewport. Smaller values fill the screen with rippling surface. default 1.0
+.TP 8
+.B \-delay \fImicroseconds\fP
+How long to pause between frames. Default is 20000, or 0.02 second.
+.TP 8
+.B \-fps
+Display a running tally of how many frames per second are being rendered.
+In conjunction with \fB\-delay 0\fP, this can be a useful benchmark of
+your GL performance.
