[gdal-dev] gdalwarp multiple nodata

[David Strip]

Just a word of caution about val-repl.py -
I recently tried to use this script and be warned that it doesn't
preserve all the properties of the input file. In my case, the input
file was a paletted geotiff and the output is grayscale, a very
different beast for my purpose. It shouldn't be too hard to fix this, as
long as you're aware of the problem.
