NAME
     chessclock - a poor mans chess clock

SYNOPSIS
     chessclock [ -m moves ] [ -t time ] [ -M contmoves ] [ -T
     conttime ]

DESCRIPTION
     _C_h_e_s_s_c_l_o_c_k is an electronic chessclock for crt's.  The space
     bar switches the clock.  The clock can be paused by `p' and
     continued by `c'.  The `q' key quits the clock.  The `!' key
     pauses the clock and forks a shell on one input line.  The
     environment variable SHELL is used if set, otherwise
     /bin/sh.  Any other key describes these options.

     By default _c_h_e_s_s_c_l_o_c_k implements five minute chess.  Each
     player has at most five minutes to play the game.  A move
     limit can be specified with -m after this many moves have
     elapsed the clocks are reset and the same number of moves
     must be played in the same amount of time.  A different
     amount of time (in minutes) can be given with the -t option.

     To give a different continuation strategy after the basic
     period one can give the continuation time with the -T flag
     and the number of moves in a continuation period with -M. If
     either of these is specified, the other defaults to the
     basic period quantity.

     Finally, argument times may be include `:' to give times in
     minutes and seconds rather than just minutes.
