+.TH GDC 6
+.SH NAME
+gdc \- grand digital clock (curses)
+.SH SYNOPSIS
+.B gdc
+[-s] [
+.I n
+]
+.SH DESCRIPTION
+.I Gdc
+runs a digital clock made of reverse-video blanks on a curses
+compatible VDU screen. With an optional numeric argument
+.I n
+it stops after
+.I n
+seconds (default never).
+The optional
+.B -s
+flag makes digits scroll as they change. In this curses mode implementation,
+the scrolling option has trouble keeping up.
+.SH AUTHOR
+Amos Shapir, modified for curses by John Lupien.
