[Gdal-dev] GDAL and Python

A couple of (maybe) useful bits of info.

MS4W has an old-gen GDAL module for Windows 
Python 2.4.  It's broken up into a number of 
pieces, and it might not be that nice to pull 
together, but you should be able to get it to work with some elbow grease.

The "old-gen" GDAL bindings do not have support 
for numpy.  I will be looking into supporting 
this in the "next-gen" GDAL  Python bindings in 
the next couple of weeks.  I have a need for this 
also, and I would like to get it tucked in before 
the next release.  Hopefully, this will remove 
any need for folks to use the "old-gen" bindings 
for anything other than legacy apps.

Python eggs and setuptools support are something that would be nice.
