But this is done! It *is* feasible to publish a GPL'd work as a
manual. It's even more feasible to do what I'm discussing, which is
to take a GPL'd manual and derive a program from it. I'm sorry for
not making that clear enough in what I wrote originally -- too much
rhetoric and too little meaning. So here it is more clearly:
I can take a GPL'd text editor, such as GNU Emacs, and derive a tetris
game or a news reader or a web browser from it. I can even derive a
manual from it. Such a book could be very interesting to read,
walking a technically savvy reader through the bulk of Emacs' code.
Because the GPL is a copyleft, all of these derivative works will be
Free Software. I think the manual will also meet your definition of
Free Documentation -- right?
I can take a GPL'd manual and derive a program from it -- this part is
clear enough that I don't think I need to write more.
I cannot take a GFDL'd manual and derive any sort of Free Software
program from it. I do not think it is too much to ask that it should
be feasible to conveniently publish a modified version of the manual
as a Free Software program.

And yet there are GPL'd books on paper, and their publishers make
money from them. Would Harry Potter be a good choice to put under the
GPL? No, probably not. Would "On Lisp"? Well, I'd love to be able
to make slides and lecture notes from it... or use some of the
big-enough-to-be-copyrightable code snippets. It has significant
The more you talk about this, the more I come to guess that a primary
motivation behind the codified, centralized GFDL is the desire to make
things convenient for publishers of printed books. Why not provide
the manuals for GNU software under a dual license: GNU GPL for those who
wish to treat the manuals like software programs, and GNU FDL for
those who wish to print books from the manuals. The FSF has
sufficient respect that it can, by example and explicit suggestion,
convince most people to dual-license their similar works -- and
controls the copyright on all of those manuals anyway, so can make
sure things are done right at the source.
This has all of the benefits of the GFDL for publishers of printed
works: they can add their "value-add" contributions and publish,
licensing to their readers only under the GFDL.
This has all the benefits of the GPL for publishers and users of
software: they can combine the manuals with other work in the Copyleft
Commons of the GPL, and can derive Free Software from the manuals.
Software programs would probably be distributed only under the GPL, as
the GFDL is awfully inconvenient for programs.
This has all the benefits of the GPL and the GFDL for the FSF and the
Free Software community, as the FSF's example would encourage most
people to dual-license their manuals under the GPL and the GFDL. It
avoids the problems you alluded to with a conversion clause, which
destroys the benefits for publishers.
