See http://jargon.watson-net.com/jargon.asp?w=top-post
and also http://jargon.watson-net.com/jargon.asp?w=bottom-post.

Searching the internet will also show a lot of links for this topic.

It boils down to this (taken from the second URL I cited):

  Hackers consider that the best practice is actually to excerpt only
  the relevent portions of the parent message, then intersperse the
  poster's response in such a way that each section of response appears
  directly after the excerpt it applies to. This reduces message bulk,
  keeps thread content in a logical order, and facilitates reading.

I'm not using SWIG myself anymore, but a Python extension module named
"example" needs a function "initexample", and an extension module named
"_example" needs a function "init_example".

IMO you should change your setup script in this way:

========================================================================
# setup.py
import distutils
from distutils.core import setup, Extension
setup(name = "Simple example from swig website",
     version = "2.2",
     ext_modules = [Extension("_example",["example.i","example.c"])])
========================================================================

Does this work (when you do 'import _example' afterwards?
