[Gdal-dev] python ng - existing scripts

[William Kyngesburye]

Ah, I thought the NG bindings were a little farther along, I guess.   
I was hoping to switch to the new bindings for my binary framework  
package, but I can wait for 1.5.  Don't want to cause problems for  
others that use my binary packages ^_^

At least I got it built with Python 2.5 (with the patched wrappers)  
and the autotests work with only a couple exceptions.
