** INSTRUCTION READ AND MAIN PLAY LOOP
**
** Well folks, this is it. Here we have the guts of the game.
** This routine executes moves. It sets up per-move variables,
** gets the command, and executes the command. After the command,
** it calls events() to use up time, attack() to have Klingons
** attack if the move was not free, and checkcond() to check up
** on how we are doing after the move.
