 WELCOME TO ROCK-PAPER-SCISSORS!

 Rules:
 1. Choose whether to play against a friend or the computer.
 2. Each human player chooses a handshape. The computer chooses one 
    at random.
 3. When both players choose the same hand shape, it is a draw. Go 
    back to step 2.
 4. When the hand shapes are different, the winner is as follows:
   (a) Rock and scissors: rock wins
   (b) Paper and rock: paper wins
   (c) scissors and paper: scissors win           
         }
