[Tilecache] ECW or TIFF to Tiles

[Jeffrey Johnson]

Then you will want to use gdaltindex to make the index shapefile and
then use gdal_translate to make one big tiff out of the individual
images. If you want to reproject to 900913 then you will need to use
gdal_translate to do that because mapnik will NOT reproject for you.
