+<h3>What are LOCATIONs and MAPSETs?</h3>
+
+A LOCATION is some geographic extent of interest that contains data sets
+that [should] all be in the same coordinate system. Every location has a
+PERMANENT directory which stores some basic information about the whole
+location, and is a good place to park base files.  You can think of a
+location as a data library for a region of interest.
+<p>
+ 
+In a MAPSET  you can organize GIS maps thematically or geographically or by
+project or whatever. Every GRASS session runs under the name of a MAPSET. A
+MAPSET may be a geographical subset or as large as the parent LOCATION.
+Technically they are subdirectories under any location. In a networked
+environment with several users working within the same location, mapsets
+play a special role. Users may only select (and thus modify) a mapset that
+they own (i.e., have created). However, data in all mapsets for a given
+location can be read by anyone (unless prevented by UNIX file permissions).
+The "PERMANENT" mapset usually contains the read-only base maps like the
+elevation model, while the other locations are readable and writable by
+their owners. The "PERMANENT" mapset also contains some information about
+the location itself that is not found in other mapsets (projection info
+etc.), thus it must exist in every location.
+<p>
+Putting LOCATIONs on a central server, a team can work inside this project
+database (usually NFS is used).
