Using 3rd Party Windows DLLs with Python

[LeeIngram]

After searching documents and Mark Hammond's excellent Win32
extensions I am still unable to identify the steps necessary to use
Windows DLLs as Python extensions. I do not want to use Active X
controls but honest-to-goodness DLLs. The DLLs are not written in C or
C++ (they can be written using Delphi or PowerBASIC). For some, the
source code is not available but the "C" callable interface is
documented.

Any help or pointers are appreciated.

Thanks in advance,
Lee
