          The rrrreeeessssiiiizzzzeeee function is used to modify the number of rows in
          an RRRRRRRRAAAA.

          _f_i_l_e_n_a_m_e
                  the name of the RRRRRRRRDDDD you want to alter.

          _r_r_a-_n_u_m the RRRRRRRRAAAA you want to alter. You can find the number
                  using rrrrrrrrddddttttoooooooollll iiiinnnnffffoooo.

          GGGGRRRROOOOWWWW    used if you want to add extra rows to an RRA. The
                  extra rows will be inserted as the rows that are
                  oldest.

          SSSSHHHHRRRRIIIINNNNKKKK  used if you want to remove rows from an RRA. The
                  rows that will be removed are the oldest rows.

          _r_o_w_s    the number of rows you want to add or remove.

          The new .rrd file, with the modified RRAs, is written to the
          file rrrreeeessssiiiizzzzeeee....rrrrrrrrdddd in the current directory.  TTTThhhheeee oooorrrriiiiggggiiiinnnnaaaallll ....rrrrrrrrdddd

          It is possible to abuse this tool and get strange results by
          first removing some rows and then reinserting the same
          amount (effectively clearing them to be Unknown). You may
          thus end up with unknown data in one RRA while at the same
          timestamp this data is available in another RRA.
