[Gdal-dev] GDAL scripting with Python 2.5 (on windows)

[Matt Wilkie]

Thanks for the effbot pointer Markus. I've been thinking for ahwile now 
that I'd like to register the gdal python as the system default for 2.5 
but didn't have a recipe and was mapping out a plan to work out some 
sort of regedit batch file trickery. Now there is a much cleaner route :)
