The title says it all, even if it is a mouthful! I need to download a file on a corporate Sharepoint site using CPython.

I also want to download the file without prompting the user to save and without prompting the user for ...
I have an application that is written in SBCL and is deployed as an executable on Windows. The need has arisen for it to interact with Excel via COM and another application via DDE (I know, I know).
