Clarify licence status for hyphenator files

[hrieke]

Hi guys-

Would it be too much to ask if you compile a list of licenses that the various contributions are licensed under, plus what the general license for this project is?
For example, the file:
https://github.com/hyphenation/tex-hyphen/blob/master/collaboration/repository/hyphenator/en_us.js

I have no idea under what terms it's licensed under.

Thank you

It’s been there for a long time, for the master files (in hyph-utf8/tex/generic/hyph-utf8/patterns/tex): http://www.hyphenation.org/tex#languages

While looking back at this ... it is true that we list the licence under the above mentioned website, but it's also true that the files we once generated for hyphenator completely lack that information and this is something we should definitely fix (or remove those generated files as part of repository clean-up process). We may also need to contact upstream hyphenator and see where we are, I'm not even sure if the format of those patterns is still compliant.
