[python-win32] Getting PyWin32 working with private Python installs

[Howard Lightstone]

I've had a private Python25 install running with win32 for a while.  I
believe the trick is that the pythoncom25.dll and pywintypes25.dll have to
be in the SAME folder as the python.exe that you want to use (due to Windoze
own variety of internal search paths for DLLs).  In my code, I also alter
the PATH to point to both the DLLs and (root) folder where the python.exe
is.   I actually have an embedded interpreter in my instance with a
subfolder of the entire Python25 installation.  I am able to run the
python.exe and use the win32 code without changing any registry items on
machines that have never had Python installed.
