Hello,

I'm not sure that using an interpreter for running some code classifies
as linking, but I don't know of any "official" statement on the subject.

On the other hand, Elisp is an extension language for a GPL program,
thus it may be argued that implicitly everything coded in Elist is an
extension of Emacs and therefore linked to it.

I believe this issue must have come up before. Does anyone have a link
to some statement from the GNU Project about this?

Cheers,
Daniele
