OK. I have a copy of Emacs here, licensed to me under the GNU GPL2.
I have made some modifications to it, and updated the changelogs and
history notes. I wish to give it to a friend. Section 2b requires
that I distribute my new program, Sniffmacs, "under the terms of this
License," GPL2. Can I give my friend Sniffmacs, together with the
"Terms and Conditions" section of the GPL, retitled as "Sniffen GPL"?
As far as I can tell, this meets the requirements for creating a new
license based on the GPL, and meets the requirements for distributing
GPL'd software.
