    4digits - A guess-the-number game, aka Bulls and Cows
    Copyright (c) 2004- Yongzhi Pan <http://fourdigits.sourceforge.net>

    4digits is a guess-the-number puzzle game. You are given eight times
    to guess a four-digit number. One digit is marked A if its value and
    position are both correct, and marked B if only its value is correct.
    You win the game when you get 4A0B. Good luck!
