.SH DESCRIPTION
The \fIgltext\fP program draws some text spinning around in 3D, using
a font that appears to be made of solid tubes.
.B \-text \fIstring\fP
The text to display. This may contain newlines, but it shouldn't be
very long. The default is to display the machine name and OS version.
+
+This may also be a format string acceptable to
+.BR date (1)
+and
+.BR strftime (3) ,
+in which case, it will be updated once a second. So to make this
+program display a spinning digital clock, you could do this:
+.EX
+gltext -text "%A%n%d %b %Y%n%l:%M:%S %p"
+.EE
+To include a literal `%', you must double it: `%%'.
+
+See the man page for
+.BR strftime (3)
+for more details.
+.TP 8
+.B \-program \fIcommand\fP
+The given program is run, and its output is displayed.
+If specified, this overrides \fI\-text\fP.
+The output of this program will be repeatedely displayed, with new
+pages of text shifting in every few seconds. Lines should be relatively
+short. You might try:
+.EX
+-program 'xscreensaver-text --cols 20'
+.EE
+.TP 8
+.B \-maxlines
+Set the number of lines of text to display. By default,
+.I gltext
+will print 8 lines of text at a time. Use this option to increase or
+decrease that number. Be aware that
+.I gltext
+is designed to work with a fairly small amount of text, so setting this
+value too high might result in slow performance or strange behaviour
+stemming from buffer overflows. Increase at your own risk.
+.TP 8
+.B \-mono
+Display the text in a monospace font. Default is a variable-width font.
+.TP 8
+.B \-no\-mono
+Display the text in a variable-width font. This is the default.
+.TP 8
+.B \-wander
+Move the text around the screen. This is the default.
+.TP 8
+.B \-no\-wander
+Keep the text centered on the screen.
+.TP 8
+.B \-wander\-speed
+Sets the speed at which the text wanders around. Default is 0.02.
+.TP 8
+.B \-spin
+Which axes around which the text should spin. The default is "XYZ",
+meaning rotate it freely in space. "\fB\-spin Z\fP" would rotate the
+text in the plane of the screen while not rotating it into or out
+of the screen; etc.
+.TP 8
+.B \-no\-spin
+Don't spin the text at all: the same as \fB\-spin ""\fP.
+.TP 8
+.B \-front
+When spinning, never spin all the way around or upside down:
+always face mostly forward so that the text is easily readable.
+.TP 8
+.B \-no\-front
+Allow spins to go all the way around or upside down. This is the default.
+.TP 8
+.B \-wireframe
+Render in wireframe instead of solid.
.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.
+Display the current frame rate, CPU load, and polygon count.
+.TP 8
+.B \-scale
+Sets the scale at which the text is rendered. Bigger values will result
+in bigger text; smaller values will result in smaller text. The default
+value is 0.01.
