I've really just started on this and at the moment I'm looking at trying to get unpack to work for some simple cases. I will be focussing on unpack first and possibly pack after that. Any help would be great - is there any specific area that you would like to work in? Time-wise it's looking like several months work to get unpack finished, as Tim suggested. > > 2.
