     """        Frogs vs Flies is a cool on-line multi-player game.
     It consists of hungry frogs, trying to catch some darn
     tasty flies to eat and not starve to death, and terrified,
     but playful flies that try to live as long as possible 
     to score points by not being eaten by nasty frogs.
     ----------------------------------------------------------------------------------------
     When the game has been selected or created, and your
     class selected, click in the game field to start feeling your
     limbs. To move, use your keyboard's arrows.
     By this point, you should know where they are located, 
     don't you? Great! Now you can start playing the game!
     ----------------------------------------------------------------------------------------
     Frogs, being cocky little things, have the ability to
     do a double jump, holding SHIFT while moving with cursors.
     And flies, being so fly, that the air can't catch up with
     them, have a greater field of view, so they can see frogs
     before they can see them.
     ----------------------------------------------------------------------------------------
     Have a wonderful time playing this awesome game!
