Yes, I am aware of that. Christian has already stated that it is OK with
him to sign papers. If there is interest in integrating lua-mode into
Emacs, I'd try to reach the other distributors mentioned in the
copyright notice and try to find out whether there are other,
unmentioned.

I see. I'll write to the (known) contributors (the package is not that
large, so it seems very probable they are all).

Yes, I'd try to do that.

Yes, I see the point.
