[$] ClearlyDefined: Putting license information in one place

Determining the license that any given package uses can be difficult, but it is
essential in order to properly comply with that license and, thus, the
developer's wishes. There
is an enormous amount of 'open source' software available these days that
is not clearly licensed, which is where the ClearlyDefined project comes
in. The project is collecting a curated list of packages,
source location, and license information; some of that collection can be
automated, but ClearlyDefined is targeting the community to provide
curation in the form of cleanups and additions.
