[Gdal-dev] jasper for very large jpeg 2000 images

[Kurt Schwehr]

Hi Frank,

Thanks for the quick feedback.  Looks like all the other drivers are 
restricted licenses that won't work with fink or windows only.  I'll put 
in jasper into the fink gdal build just to have something in there for 
people with smaller images.

Thanks,
-Kurt
