[GRASSLIST:1320] Mac OS X Public Beta Starting

Hello, I checked all mailing lists and manuals but still am confused on this
part. LOCATION, MAPSET and DATABASE: What do I type in terminal for
these? Thanks
Mac OS X Public Beta

LOCATION: This is the name of an available geographic location. -spearfish-
          is the sample data base for which all tutorials are written.

MAPSET: Every GRASS session runs under the name of a MAPSET. Associated
          with each MAPSET is a rectangular COORDINATE REGION and a list
          of any new maps created.

DATABASE: This is the Unix directory containing the geographic databases

         The REGION defaults to the entire area of the chosen LOCATION.
         You may change it later with the command: g.region
