You've got a problem with this one, because licenses can be combined
conjunctively and disjunctively. So a package might be both entirely
under foo and entirely under bar (foo || bar), or it might be
partially under foo and partially under bar (foo && bar).

And last I checked, debtags wasn't really equipped to express stuff
like that.
