       rr..llee..ttrraaccee - the _r_._l_e_._t_r_a_c_e program can be used to display the boundary
       of each patch  and  show  how  the  boundary  is  traced,  display  the
       attribute,  size, perimeter, and shape indices for each patch, and save
       the data in an output file.

       When sampling the whole map (sam=W), the _r_._l_e_._t_r_a_c_e program can be used
       to do three things: (1) display the boundary of each patch and show how
       the boundary is traced, (2) display the attribute, size, perimeter, and
       shape  indices  for  each  patch,  and (3) save these data in an output
       file.

       --nn     Output map 'num' with patch numbers.

       --pp     Include sampling area boundary as perimeter.

       --tt     Use 4 neighbor tracing instead of 8 neighbor.
