Building Emacs against an external free library, or using an external
application for some Emacs-related job, is not what I had in mind.  If
this was your point, then I didn't ignore it, I just described an
issue with a different way of "borrowing" code: directly copying code
into our sources.  That cannot be done unless the author agrees, and
for substantial amounts of such code we need a copyright assignment.

I just wanted people to be aware of this.  It is better to be aware of
that up front than to use the "borrowed" code in a submission to
Emacs, just to learn that we cannot accept such a submission.
