The GPL license document "COPYING" is not DFSG-free
What's the dispensation on this:
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
I thought the whole hoopla over GFDL was invariant sections.
The entire GPL license is non-modifiable.
(1) Doesn't this mean that the GPL is not DFSG-free?
(2) Aren't slightly-different wordings of the GPL to produce
slightly-different licenses derivative works of the GPL [they certainly
are in spirit] and thus covered by the GPL?
