       _r_._o_u_t_._a_r_c  converts a user-specified raster map layer (iinnppuutt==_n_a_m_e) into
       an ESRI ARC-GRID ascii file (oouuttppuutt==_n_a_m_e) suitable for export to  other
       computer  systems.  The dp=_v_a_l_u_e option (where _v_a_l_u_e is a number of the
       user's choice) can be used to request that numbers after decimal points
       are  limited.   However,  to use this, the user should know the maximum
       number of digits that will occur in the output file.  The user can find
       the  maximum  number  of digits occurring in the output file by running
       _r_._o_u_t_._a_r_c without the ddpp==_v_a_l_u_e option.


       The GRASS program _r_._i_n_._a_r_c can be used to perform the reverse function,
       converting  an  ESRI  ARC-GRID  ascii  file in suitable format to GRASS
       raster file format. The order of cell values in file is from lower left
       to upper right (reverse to GRASS).

       --hh     Suppress printing of header information.

       iinnppuutt==_n_a_m_e
	      Name of an existing raster map layer.

       oouuttppuutt Name of an output ARC-GID map (use output=- for stdout)

       ddpp==_v_a_l_u_e
	      The minimum number of decimals (per cell) to be printed.

       _r_._o_u_t_._a_r_c  can  be  run either non-interactively or interactively.  The
       program will be run non-interactively if the user specifies the name of
       a  raster  map  layer  and  (optionally) a value for _d_p, using the form
       rr..oouutt..aarrcc iinnppuutt==_i_n_n_a_m_e oouuttppuutt==_o_u_t_n_a_m_e [ddpp==_v_a_l_u_e]

       where _i_n_n_a_m_e is the name of a raster map layer to be converted to  ARC-
       GRID  format, _o_u_t_n_a_m_e is the name of a raster map layer to be exported,
       and _v_a_l_u_e is the minimum number of digits (per cell) to be  printed  to
       output.	The user can also the --hh option to suppress the output of file
       header information.


       Alternately, the user can simply type rr..oouutt..aarrcc on  the	command  line,
       without program arguments.  In this case, the user will be prompted for
       parameter values using the standard GRASS _p_a_r_s_e_r interface.

NNOOTTEESS
       The output from _r_._o_u_t_._a_r_c may be placed into a file by using  the  UNIX
       redirection mechanism;  e.g.: rr..oouutt..aarrcc iinnppuutt==soils oouuttppuutt==-- > out.grd

       The  output file _o_u_t_._g_r_d can then be copied onto a CDROM or floppy disk
       for export purposes.
