30ASDEMDCW data with grass

Hello to all grass users.

Has anybody allready tried to import and use the 30 arc second DCW DEM
data from the USGS (edcftp.cr.usgs.gov in /pub/data/30ASDCWDEM) in
GRASS 4.1 (XGRASS) on a linux system? It actually should be the same
as on an other UNIX system.

I am a beginner in GRASS and GIS. So please be not bad with me if this
is a stupid question.

Thanks a lot for any answer, Ulli
