       The  _r_._r_e_g_i_o_n  program  allows  the  user to manage the boundaries 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  latter  function,
	      use the rraasstteerr==_n_a_m_e option.


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