- ** 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.
