Pretty much so.
Also be sure to look at GrAtscDeinterleaver.cc and
GrAtscInterleaver.cc, especially the comments about "pipeline info is
handled in the primitive". Looks like that's handled differently in
the RS encoder than in the interleaver.
for (unsigned int i = 0; i < output.size; i++){
// pipeline info is handled in the primitive
deinterleaver.deinterleave (out[i], in[i]);
}
