       The _r_._r_e_g_i_o_n program allows the user to manage the  bound-
       aries  of a raster map. These boundaries can be set by the
       user directly and/or set from  a  region  definition  file
       (stored	under the windows directory in the user's current
       mapset), a raster or vector map, or a 3dview file.

   FFllaaggss::
       --cc     Set the boundaries to those of the current  region.

       --dd     Set  the boundaries to those of the default region.


   PPaarraammeetteerrss::
       mmaapp==_n_a_m_e
	      Raster map whose boundaries are to be set

       rreeggiioonn==_n_a_m_e
	      Obtain the boundaries  from  the	specified  region
	      file

       rraasstteerr==_n_a_m_e
	      Obtain the boundaries from the specified raster map

       vveeccttoorr==_n_a_m_e
	      Obtain the boundaries from the specified vector map

       33ddvviieeww==_n_a_m_e
	      Obtain  the  boundaries  from  the specified 3dview
	      file

       nn==_v_a_l_u_e
	      Set map coordinate value	for  the  map's  northern
	      edge to _v_a_l_u_e

       ss==_v_a_l_u_e
	      Set  map	coordinate  value  for the map's southern
	      edge to _v_a_l_u_e

       ee==_v_a_l_u_e
	      Set map coordinate value for the map's eastern edge
	      to _v_a_l_u_e

       ww==_v_a_l_u_e
	      Set map coordinate value for the map's western edge
	      to _v_a_l_u_e

       aalliiggnn==_n_a_m_e
	      Set the current resolution equal	to  that  of  the
	      named raster map, and align the boundaries to a row
	      and column edge in the named map.   Alignment  only
	      moves  the existing boundaries outward to the edges
	      of the next nearest cell in the named raster map --
	      not  to the named map's edges.  To perform the lat-
	      ter function, use the rraasstteerr==_n_a_m_e option.


NNOOTTEE
       After all updates have been applied, the raster map's res-
       olution	settings  are  recomputed from the boundaries and
       the number of rows and columns in the raster map.
