Add copyleft compliance class
Deploys sources for recipes for compliance with copyleft-style licenses Defaults to using symlinks, as it's a quick operation, and one can easily follow the links when making use of the files (e.g. tar with the -h arg). By default, includes all GPL and LGPL, and excludes CLOSED and Proprietary.
