> Not all files are covered by LPPL. Having co-authored the full list on http://www.tug.org/tex-hyphen/#languages I'm very much aware of that. This is a situation to be expected and authors should choose whatever licence they think is best for their contribution; but that wasn't my question. Since the LPPL is a very popular choice in the TeX world, for obvious reasons, it would be good to get a clear idea of how compatible it is with other licences.
Best,
