There are 3 different releases of this application each compiled with
different versions of Visual Studio, 2008, 2010, and 2012.

Hello,
I'm extending an application that supports customization using the C

I am able to write standalone python applications that use the C API's

This is good, but only a first step.

Hopefully a simple question.
Basically, I'd like to know how to create a proper setup.py script to

The package exists as a single directory with a single __init__.py

Hello,
I created some bindings to a 3rd party library.
I have found that when I run Python and import smtplib it works fine.
If I first log into the 3rd party application using my bindings however I
get a bunch of errors.

What I wanted to implement was a debugging console that runs right on the
client rather than on the server.
You'd have to be logged into the application to do anything meaningful or
even start it up.
All of the C functions that I created bindings for respect the security of
the logged in user.

Sometimes the code runs through but sometimes it just freezes for no

This is behavior contradicts the documentation which says the value

Py_Main doesn't return anything, it just exits.

Hello,
I have an extension module for a 3rd party library in which I am

My initial attempt worked okay on Windows but failed on Linux.
I was doing it in two parts.
The first part on the C side of things I was turning the entire
structure into a char array.
The second part
I am attempting to automate the building of binding for a 3rd party library.
The functions I'm wrapping all return an integer of whether they
failed and output are passed as pointers.
There can be multiple return values.
So the code that I generate has a PyObject* called python__return_val

Are you saying that in python when I say from "Spam.ABC import *" I
need a file called "Spam.ABC.[so|pyd]"?
