+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)

+.B \-program \fIcommand\fP
+The given program is run, and its output is displayed.
+If specified, this overrides \fI\-text\fP.

+.B \-no\-wander
+Keep the text centered on the screen.

+.B \-no\-spin
+Don't spin the text at all: the same as \fB\-spin ""\fP.

+.B \-no\-front
+Allow spins to go all the way around or upside down. This is the default.
+.TP 8
+.B \-wireframe
