Even the GDFL (Gnu free documentation license) has restrictions on
copying, with their "invariant sections". This is why a lot of GNU
documentation is distributed as nonfree by Debian.

Although not designed for the purpose, I would advise licencing
documentation and media under the same licence as the code (in
*addition* to any other possibly more approriate licence like CC or
GFDL) in case some future modifier of the code would find it
convenient to include it as part of the executable.

I wrote a free game
(http://topoi.pooq.com/hendrik/dv/free/fun/wander/index.html) once
as part of the liberated pixel cup challenge
(http://lpc.opengameart.org/), and I can't put the images
into the executable as initialized data because of their licenses.
