       _r_._i_n_f_o reports some basic information about a  user-speci-
       fied  raster  map layer.  This map layer must exist in the
       user's current mapset search path.  Information about  the
       map's boundaries, resolution, projection, data type, cate-
       gory number, data base location and  mapset,  and  history
       are  put into a table and written to standard output.  The
       types of information listed can also be found in the _c_a_t_s,
       _c_e_l_l_h_d, and _h_i_s_t directories under the mapset in which the
       named map is stored.


       The program will be  run  non-interactively  if	the  user
       specifies  the  name  of a raster map layer on the command
       line, using the form: rr..iinnffoo mmaapp==_n_a_m_e

       where _n_a_m_e is the name of a raster map layer on which  the
       user seeks information. The user can save the tabular out-
       put to a file by using the UNIX redirection mechanism (>);
       for example, the user might save a report on the _s_o_i_l_s map
       layer  in  a  file  called  _s_o_i_l_._r_p_t  by  typing:   rr..iinnffoo
       mmaapp==_s_o_i_l_s > _s_o_i_l_._r_p_t

       Alternately,  the  user can simply type rr..iinnffoo on the com-
       mand line, without program arguments. In  this  case,  the
       user  will  be prompted for the name of a raster map layer
       using the standard GRASS _p_a_r_s_e_r interface.   The  user  is
       asked whether he wishes to print the report and/or save it
       in a file.  If saved, the report is stored in a user-named
       file in the user's home directory.


       Below  is the report produced by _r_._i_n_f_o for the raster map
       _g_e_o_l_o_g_y in the Spearfish sample data base.
