       gg..sseettpprroojj   -  Allows the user to create the PROJ_INFO and
       the PROJ_UNITS files to record the projection  information
       associated with a current location.

       gg..sseettpprroojj

DDEESSCCRRIIPPTTIIOONN
       Allows  a user to create a PROJ_INFO file in the PERMANENT
       mapset of the current location. PROJ_INFO file is used  to
       record  the  projection	information  associated  with the
       specified mapset.

NNOOTTEESS
       User running _g_._s_e_t_p_r_o_j must own PERMANENT mapset.   It  is
       highly  recommended  to run _g_._s_e_t_p_r_o_j after creating a new
       location so that conversion programs (such as _v_._p_r_o_j)  can
       be run.


       The  current  location  must  not  contain  a PROJ_INFO or
       PROJ_UNITS file.


       The user will be prompted for the projection name.


       The specification of any projection other than ll and  stp
       will  generate a request to the user for a name of a stan-
       dard ellipse.


       The user will be asked for a map datum. If  no  map  datum
       support	is  needed,  the question should be answered with
       no, so that no map datum is  specified  in  the	PROJ_INFO
       file.   The program assures that the ellipsoid matches the
       ellipsoid defined with the map datum from the datum  table
       within  GRASS.  If the map datum used is not listed within
       this program, the user/administrator should add the  defi-
       nition to the systems datum.table.  If the ellipsoid spec-
       ified does not match the one from the  definition  in  the
       datum table, the program exits with an error.


       The  projections of aea, lcc, merc, leae (GRASS 5.x), leac
       (GRASS 5.x), and tmerc will generate a request to the user
       for  the prime meridian and standard parallel for the out-
       put map.


       The projection of stp will generate a request to the  user
       for the choice of zone for the output map.


       The user will be prompted for the spheroid and zone of the
       UTM projection.
