help selecting mapsets

[Lee Graham]

When you run g.mapsets, the order that you specify the mapsets determines
precedence as far as access for identical filenames.  If you have mapsets 
A,B,C, and PERMANENT and g.mapsets tells you that the current setting is
PERMANENT,A,B,C, a file called vegtype in PERMANENT would be accessed 
preferentially over one called vegtype in mapsets A,B,and C. Likewise, vegtype
in A would have precedence over vegtype in B and C.
To change precedence, just use g.mapsets to specify a different order, then
you have control over which vegtype map rules.
