I may need to generate my own raster tileindexes myself soon, and
based on what I've read about gdaltindex, it should be fairly easy to
do.

If I've understood everything correctly, all you have to do, is
generate a shapefile with rectangles that has the same coordinates as
the boundaries of each raster file. Then, the path to that file needs
to be placed in the field "location" in the dbf-file that accompanies
the shapefiles.

I'll take a stab at making a perl-utility for this tomorrow. I'll let
you know how it turns out.
