We have a standard in place to distinguish between different versions of
the GPL, for v2 and v3. Out standard also allows to distinguish between
v2 only and v2 or later.

It would be nice to distinguish between GPLvN only and GPLvN or later
for any N. The question is which way is optimal.

Not exactly true. Perl and pretty much any Perl package is Artistic
license and GPLv1 or later. Out Perl package says Artistic and GPLv2 or

I'm not sure what you mean by that. Not counting LGPL and the likes
there are 3 GPL license texts, v1, v2 and v3. I think no matter whether
the program is distributed as 'v2 or later' or 'v2 only' it would be
sufficient to link it with the v2 text.

I understand that this is the main problem, a change to a new system
would either be another hack or require a change in basically every
Maybe we can:
1) come up with a scheme that is intuitive and future proof, that we can
all agree on.
2) come up with a way that allows a slow transition to the new system,
so that it doesn't require extra effort and rebuilds.

So mysql is distributed as GPL v2 only, but they added an exception to
make it compatible with any of the license in the list. In this case I'd
say GPLv2 only + custom or just custom (I'm not sure about the details),
but [extra] says: License=('GPL').
