Usually, all you have to do in here is:-

1) Initialise the logging package as you see fit (or not at all ;^)!

2) Set the 'EGG_PATH' variable to be a list of the directories that contain
   your application's eggs.

3) Edit the 'run' function to do whatever you need to do to start your
   application.
