I would really like to see an example or situation that makes good
use of the __init__.py file.
I've attached a non-trivial example, from my
PyGUI package. It uses some trickery to switch
in one of a number of subdirectories of platform
specific code, and then imports a bunch of names
from submodules into the top-level package, so
the user can pretend he's just using a single
top-level module, e.g.
from GUI import Window
even though Window is actually defined in some
submodule.
This is a rather extreme example, though -- most
__init__.py files are much simpler!
