     bs - battleships game

     bs [-b | -s] [-c]

     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 hack(6) motion keys hjklyubn.

     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

     The command-line arguments control game modes:

     -b	    Selects a `blitz' variant.	This allows a side to shoot for as
	    long as it continues to score hits.

     -c	    Permits ships to be placed adjacently.  Normally, ships must be
	    separated by at least one square of open water.  This disables
	    that check and allows them to close-pack.

     -s	    Selects a `salvo' variant.	This allows a player one shot per turn
	    for each of his/her ships still afloat.  This puts a premium on
	    scoring hits early and knocking out some ships and also makes it
	    much harder, for example, when you face a superior force with only
	    your PT-boat.

     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 <>,
     August 1989.

     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.
