OK. But is that a problem for going GPLv3 or later?
No, we just have to say that they're not part of XEmacs if asked, but
they are bundled with XEmacs. Nothing in XEmacs depends on them, they
are data that is read in if available.
A quick check in the Emacs repo shows that most TUTORIALS have the
old license still.
Interesting, but not very surprising. Either the standard for getting
tutorials is lower (ie, no assignment required) and they face the same
problem that we do (authors have disappeared and they can't change the
license), or perhaps it's just a lack of thoroughness on the part of
the people who did the work.
The English TUTORIAL is GPLv3 or later though!
So it seems we can just let them be!?
Yes. *We do not have a choice about the tutorials.* All of our
tutorials derive from our English tutorial, and perhaps Emacs
versions, which have the old license. Therefore they inherit that
license (it is a copyleft license), and we need the permission of all
copyright owners in the chain to change them.
However, since the FSF has historically distributed in this fashion,
apparently they don't consider the tutorials to be part of Emacs, so I
don't see any reason why we shouldn't do the same as they do.
Thanks for following up and checking on "What Emacs Does". It's very
