basic features working

All of the features necessary to automatically download (non-redundant) PDB files and automatically extract distances, angles, and sequence information from them are working. (The DNA coarse grained model featured in the cover image was built using the measurements obtained by this version of the software.)

What's lacking is better documentation and a better interface.
(...and I don't know if I'll ever bother with that, unless someone asks for it. This is not a very popular program.)
