I agree using external data files would be better. I just stole the
code for the licenses from the old mkcabal project, and decided
improving it to use external data files was a "nice to have" feature I
didn't end up getting around to. Mikhail, can you add a feature
request ticket for this on the bug tracker? I might get around to it
at some point but in the meantime anyone else is obviously welcome to
have a go (should be a nice easy project for someone wanting to get
their feet wet).
