The r.out.geotiff script is confusing because it would lead the user to
believe it creates a GeoTIFF file when it does nothing of the sort. It
just uses r.out.tiff to create the file, writes a tiff world file and
a text files with some other info. A GeoTIFF file actually has all the
projection/datum/rotation/cell size/etc... info encoded in it.
r.out.geotiff essentially produces something compatible with ESRI's
ArcView and Arc/Info (like r.out.arctiff does...). I think we need to
nip this confusion in the bud. I'll take care of it if nobody objects.
