       mm..fflliipp  - Flips elevation data extracted from systems that
       retrieve data by rows from south to north.

       _m_._f_l_i_p  is  similar to _m_._r_o_t_9_0 a raster file, _m_._f_l_i_p flips
       the contents of the raster generated  by  tape  extraction
       programs about the east-west axis.  Flipping may be neces-
       sary to compensate for the orientation of  the  data  read
       from  tape.   This program can be used in conjunction with
       the program

       _r_._i_n_._l_l
	to convert this rotated data into GRASS raster format.


       _m_._f_l_i_p requires five inputs to be  entered  by  the  user.
       These   parameters  and	the  optional  flag  setting  are
       described below.



   FFllaaggss::
       --qq     Run quietly, suppressing output of messages on pro-
	      gram progress to standard output.




   PPaarraammeetteerrss::
       iinnppuutt==_n_a_m_e
	      The  full  pathname  of an existing file containing
	      the data to be flipped.

       oouuttppuutt==_n_a_m_e
	      The full pathname of the output file in  which  the
	      rotated data are to be stored.

       rroowwss==_v_a_l_u_e
	      The number of rows of data in the _i_n_p_u_t file.  Val-
	      ues must be positive integers.

       ccoollss==_v_a_l_u_e
	      The number of columns of data in	the  _i_n_p_u_t  file.
	      Values must be positive integers.

       bbppcc==_v_a_l_u_e
	      The number of bytes per cell (i.e., per data value)
	      in the _i_n_p_u_t file.  Values must be  positive  inte-
	      gers.

       The following command:


       mm..fflliipp  iinnppuutt==_/_t_m_p_/_f_o_o_._o_u_t  oouuttppuutt==_/_t_m_p_/_f_l_i_p_._o_u_t  rroowwss==_3_0_1
       ccoollss==_3_5_8  bbppcc==_2



       will rotate the file /tmp/foo.out, and place  the  rotated
       file  in  /tmp/flip.out.  Here, the input file is 301 rows
       by 358 columns, at 2 bytes per data value.
