mines lets you explore a mine.  The object of the game is to
  visit all of the rooms and return all the treasures to the
  entrance without making too many moves.

  Usage:  mines <MineNumber>
    where a each mine number gives a different mine.

    The program reads descriptions of the rooms from the file
    "rooms.dat" and descriptions of treasures, guardians, and
    weapons from "treasure.dat"; see "notes.txt" for details.

Example:  mines 1

Commands in the game are "N", "E", "S", "W", "U", and "D" to
move North, East, South, West, Up, or Down, respectively.  
Other commands are "C" to carry things, "I" to inventory 
what you are carrying, "L" to leave treasures, "P" to get 
the points you've scored, "O" for help getting out of the 
mine, "H" for help, and "Q" to quit.

In a mine, the passages are straight.  So, for example, if 
you go North to leave a room, you can go South to reenter 
it.  The rooms are not evenly spaced.  However, the distance
between adjacent rooms is always a multiple of the minimum 
distance between adjacent rooms.
