[$] ClearlyDefined: Putting license information in one place

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