[GRASS-user] USGS SDDS DEM to Grass HOWTO??

I'm missing some secrets for downloading DEM data from the USGS SDDS
(Seamless Data Distribution System) into GRASS.
I'm using GRASS-6.2.1 as a downloaded binary for Fedora Core 6. I would
like to download DEM data for various areas and import the data into
GRASS, with each area going into a separate location.
I've tried various formats for downloading the data (ArcGrid, geotiff,
BIL). I get everything in a single zip file, put it in its own
directory, and unzip it, which produces a set of files including both
data and metadata. I can set up a location using the "Define new
location using georeferenced file" option, and the new location exists
when I restart GRASS, but I have been unable to get the actual data to
import, either through the gui or directly with a call to r.in.gdal
(which brings up the gui anyway). I have tried specifying each of the
files in the data as the file to import, but none of them seems to work.
Is there a HOWTO available for this process? If not, can anyone point
me in the proper direction? Any help will be much appreciated...
