       allows a user to convert a vector map in a specified mapset of a speci-
       fied  location  (different from current) with projection of input loca-
       tion to the vector map in a current mapset  of  current	location  with
       projection  of current location (both projections are defined by corre-
       sponding PROJ_INFO files).


       _v_._p_r_o_j will create _d_i_g, _d_i_g___a_t_t, and _d_i_g___c_a_t_s directories in the output
       mapset, if they do NOT exist.  Map files for _d_i_g, _d_i_g___a_t_t, and _d_i_g___c_a_t_s
       are also created for the new map layer.

   FFllaaggss::
       --ss     Automatically run "v.support" on newly created vector file.

       --ll     List vector files in input location and exit


   PPaarraammeetteerrss::
       iinnppuutt==_n_a_m_e
	      Name of the input vector map.

       llooccaattiioonn==_n_a_m_e
	      Name of the location containing input vector map

       ddbbaassee==_n_a_m_e
	      path to GRASS database of input location

       mmaappsseett==_n_a_m_e
	      Name of the mapset containing input vector map

       oouuttppuutt==_n_a_m_e
	      Name of the output vector map.



       If the user simply types vv..pprroojj without specifying parameter values  on
       the command line, the program will prompt the user to enter these.

NNOOTTEESS
       If oouutt is not specified it is set to be the same as input map name.
       If ddbbaassee is not specified it is assumed to be the current database.
       If sseett is not specified, its name is assumed to be the same as the cur-
       rent mapset's name.


       v.proj supports transformations between nad27 and nad83.   It  performs
       the  transformation  automatically  based on the datum specified in the
       mapset region.  See BUGS section.

BBUUGGSS
       Currently v.proj does not support general datum conversions.   It  only
       supports  conversion between nad27 and nad83, and only within the CONUS
       conversion grid; 20 degrees to 50 degrees north latitude, 63 degrees to
       131  degrees  west  longitude.  That covers all of the conterminous USA
       plus Mexico north of Mexico City and most of Canada farther south  than
       Winnipeg, Manitoba.
