Ok, then at least we agree about what to do.  That's good. :-)

Well, they should.  Since version 3 is released, "version 2 or later"
means "version 2 or version 3" (and it expands when new versions get
released).  So it is really dual-licensed.  Version 2 and version 3 are
really two different licenses, and users may choose any one of them.
In such a case, the ftp-masters should IMO demand full text of all
options.  That means both versions.

Which is both v2 and v3 if it has the "or later" clause.  V3 is not
magically included in v2 just because it says "new versions may be
released".

Sorry, I should have been more clear.  What I meant is that providing
the full license text (directly or through a link) is a service that
Debian provides to its users (it does this by writing it in policy).

They would, but not because it is legally wrong, or means the wrong
thing.  Just because it is unnecessarily confusing the issue.

We distribute it under "v2 or later".  We _can_ choose to accept only
v2, and distribute it as such, but we don't.  So only providing the v2
text (through a link or otherwise) is not enough if we want the full
license terms.

More practically, if I am a user and I want to use part of the code in a
v3 or later program, I will need to receive the program licensed as v3.
I think you will agree that I am allowed to accept only v3 if I want to.
But if I look in debian/copyright, knowing that Debian always puts all
acceptable license terms in there, I find only version 2.  The license
text that I want to accept is not there, even though I should be able to
accept it.  That's wrong.

No, I should tell mutt that I'm subscribed to this list.  I'll do that
after this mail, so please ignore it once again. :-)

Thanks,
