+.TH BATTLESHIPS 6 "Aug 23, 1989"
+.SH NAME
+bs \- battleships game
+.SH SYNOPSIS
+bs [ -b | -s ] [ -c ]
+.SH DESCRIPTION
+This program allows you to play the familiar Battleships game against the
+computer on a 10x10 board. The interface is visual and largely
+self-explanatory; you place your ships and pick your shots by moving the
+cursor around the `sea' with the rogue/hack motion keys hjklyubn.
+.PP
+Note that when selecting a ship to place, you must type the capital letter
+(these are, after all, capital ships). During ship placement, the `r' command
+may be used to ignore the current position and randomly place your currently
+selected ship. The `R' command will place all remaining ships randomly. The ^L
+command (form feed, ASCII 12) will force a screen redraw).
+.PP
+The command-line arguments control game modes. 
+
+.nf
+	-b selects a `blitz' variant
+	-s selects a `salvo' variant
+	-c permits ships to be placed adjacently
+.fi
+
+The `blitz' variant allows a side to shoot for as long as it continues to
+score hits.
+.PP
+The `salvo' game allows a player one shot per turn for each of his/her ships
+still afloat.  This puts a premium scoring hits early and knocking out some
+ships and also makes much harder the situation where you face a superior force
+with only your PT-boat.
+.PP
+Normally, ships must be separated by at least one square of open water. The
+-c option disables this check and allows them to close-pack.
+.PP
+The algorithm the computer uses once it has found a ship to sink is provably
+optimal. The dispersion criterion for the random-fire algorithm may not be.
+.SH AUTHORS
+Originally written by one Bruce Holloway in 1986. Salvo mode added by Chuck A.
+DeGaul (cbosgd!cad). Visual user interface, `closepack' option, code rewrite
+and manual page by Eric S. Raymond <esr@snark.thyrsus.com> August 1989.

+.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.
