   I'm trying to obtain hydrography data sets for the state of Nevada from
the National Hydrography Database website, <http://nhd.usgs.gov/data.html>.
The 'Quickstart' guide says data are available as shapefiles, but I cannot
find those. The other data format is ESRI's 'personal geodatabase format'
and that's all I found. I've no idea if GRASS can read these files for

   Here's a partial directory list:

a0000001c.freelist     a00000032.freelist         a00000045.gdbtable
a0000001c.gdbindexes   a00000032.gdbindexes       a00000045.gdbtablx
a0000001c.gdbtable     a00000032.gdbtable         a00000046.N_1_EStatus_0.atx
a0000001c.gdbtablx     a00000032.gdbtablx         a00000046.gdbindexes
a00000025.G1ComID.atx  a00000032.spx              a00000046.gdbtable
a00000025.G1DuuID.atx  a00000033.gdbindexes       a00000046.gdbtablx

   Can I use these?
