Hi,

> 3) test for S-57 support with 'ogrinfo --formats | grep S57'
> 4) Try to load it with a nice viewer like Quantum GIS (www.qgis.org)
> 5) Import S-57 data into GRASS GIS (grass.osgeo.org) with v.in.ogr

got lost at this point. How can I import S-57 maps in GRASS? I need to
create a new location, right? Where are the info needed to create it?
