Description:

* Generated files without source: source package doesn't contain sources for files generated e.g. by stripping comments from dtx files using docstrip. All packages checked have these sources on CTAN, it's just a problem of Arch packaging.

* Not all files have license

* Missing files: LPPL requires including descriptions of changes and a reference to unmodified source if distributing package modified by e.g. removing some files.

* MeX license: cs includes files based on pl, also has files without licenses or just with copyright notices.

* Public domain: in some jurisdictions works cannot be put into the public domain by authors, so checking if these packages were made there or if they include a free license is needed.

* BSD-style license, not included: packages affected are context-filter, context-mathsets, context-vim.

* Missing uncommon free license text: packages like de-macro not including GPL, LGPL or LPPL are not listed here.
