Comment 1 for bug 1435974

The central concern of this issue is the ambiguity of ownership and licensing. ALL project have licences, but not all licences say who owns the copyright! We often see a generic licence file, then many files with copyright information. The owner of the files is not the owner of the licence. We can address the ambiguity by ensuring each project has a licence file that explains the copyright, then the licence (not the whole licence, just the paragraph that points to the licence). For example, the github.com/juju/charms/LICENCE file could be just this

    This package parses juju charms.
