Hi list (and Hi Karl),

May I forward this question I asked this morning and the reply that I
just got from Gerd?

A bit of context: I am the author of the arabluatex package which is
licensed under the terms of the GPL v3, and is part of TeXLive too.

I am thinking of choosing a license for the documentation and was
considering CC BY-CA as a possible option.

Would that choice be ok for TeXLive?

Many thanks for this quick reply.  Now I understand much better how
things have been done over the past years.

I'll drop a line to Karl Berry later on just to be absolutely sure
that CC BY-CA license is ok for TexLive too: I could not stand not
even for a second being banned from CTAN or TeXLive!

One final question: if I choose CC BY-CA for the documentation, what
should I pick in the list that is currently presented by the upload
