[python-win32] Referencing SimpleCOMServer-based COM object fromVisStudio C# code?

You need to provide a typelibrary that describes your object.  Pywin32
doesn't come with tools to automatically create typelibs from your .py code,
but it is capable of tieing your externally created typelib and your .py
implementation together.  Thus, you need something like the MSVC tools to
create it.  Check out the 'pippo' samples in the win32com\test directory
(but its still not pretty).  Check the archives of this list for some
discussions about adding better support to pywin32, incase you are
interested...
