       _r_._i_n_f_o reports some basic information about a user-specified 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, category 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.

       mmaapp==_n_a_m_e
	      name of an existing raster map layer

       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 output 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 command line, with-
       out  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.
