/*
  procball

  This is a zero player simple and fun simulator of football matches with
  procedurally generated players and teams from many countries. Ideal for
  watching football when you don't have TV or Internet at hand :) You can run
  your own championship whenever and wherever you want. There are over 4 billion
  unique matches, each one having with ID by which you can replay the match at
  any time, or share it with a friend. Players are procedurally generated based
  on their country, each one having many attributes including name, height,
  weight, preferred foot, speed, strength, intelligence etc. Dislike what
  players you got on your favorite team? Just change season -- different ones
  will be generated. But please keep in mind that the game is minimalist,
  simplified (no offside, no cards, ...) and aimed at fun, not realism.
