Steps for importing USGS DLG files

1. Download from EROS Data Center (keep .gz suffix)
2. Unzip file using gzip -d fname
3. Divide into 80 character lines: fold fname > newfname
4. Import into GRASS: v.import
   Options:
        1
        newfname
        y UTM projection (sometimes not asked)
        n Lines, not Areas
        n Don't do multiple attribute (runs out of memory on my machine)
        n Don't snap
