pappy is a nice cornerplotting package, available at http://github.com/drphilmarshall/pappy

It would be nice to be able to have DNest3 output files in a format that is suitable for direct input to pappy. Alternatively, I could write a small script to load the DNest3 output files and create a pappy-compliant file.
