    "Event-driven program" means that your code gets called when an event
    occurs:

      - your onCommand method gets called when the user types something
      - your onReceive method gets called when a packet arrives
      - your timer methods get called when a timer expires

    Besides threaded programming, you can also contrast an event-driven
    program to a polling program, where your code runs a single main loop that
    checks to see if any of these things have happened.

    Cheers,
    Janet
