[osgeo4w-dev] Python GIS programming environment under Windows

[Gilles Bassière]

Thanks to both of you.

Adding %osgeo4w_root%\bin to the path solved the msvcr71.dll problem and
I've been able to use Pythonwin.

With Alex's batch file, I've been able to import the GDAL Python bindings
which would not load otherwise. I don't understand why the GDAL Python
bindings are not made available on the python path by the gdal-python. For
other package (e.g. mapnik), it works out of the box.

I've also been able to install the geopy package. For this, I had to remove
the setuptools dependency in the setup.py.

Best regards,
Gilles
