If I find a program in = C (gpl3) and I adapt it to Emacs Lisp what is the situation regarding
authorship/copyright/licence ?

= Please elaborate on what you mean by "adapt it to Emacs Lisp".

It is a single file c source game that you can = run from the command line and I would like to rewrite it in elisp.

IANAL, but AFAIK rewriting in a = completely different programming
language doesn't qualify = as "copying", so for all practical purposes
the Lisp code = will be yours and yours alone (although referring to the
C = implementation as the source of the general idea and the design
would be a Good Thing).

Thank you. = After tweaking a few lines here and there as I've done in the past 12 = months, I guess it is time to move to writing a full, even short, = program.
