Can somebody confirm or reject this, and maybe also edit/comment on the
Wikipedia article, such that confusion like this can be avoided?
Particularly, the [2] they refer to is http://www.apache.org/licenses/,
but I cannot find that information there, or probably I am
misinterpreting stuff.

Indeed, thanks, but I am afraid I am in situation 2, which unfortunately
contains no specific guidelines.

Let me explain my problem again: if I include the jar into my jar, the
jar program takes over the files LICENSE and NOTICE from the META-INF
directory, which are put there by the CLI build system.  However, If
people were to look inside my jar (without going to the website, because
there it is clearly indicated that I use GPL3), they would then come
under the false impression that I use the Apache license, since they
will see a file LICENSE, open it and see the Apache license.  Please
give some advice on how to avoid this confusion.  E.g. can I rename the
file Apache-LICENSE or something.  The NOTICE file is also included
there, but that is fine.  For example, I could put the file COPYING
there as well, as usual in GNU projects.

Wait a moment, on second reading, I see no obligation to include the
LICENSE file, only the NOTICE file.  Then it’s easy: I replace the
LICENSE file with COPYING and leave NOTICE intact.  Am I correct here?

I suppose there will be no way around putting a notice in each file I
changed, but I am fine with that.

Also, people are able to check out code from my svn repo.  If they do
that, they will get a CLI jar as produced by its build file, so there I
think it is enough that the NOTICE and LICENSE files are in the metadata
directory, since the other files are only class files, which are binary,
so my changes cannot be recognized anyway.  I do not have the changed
CLI files in my repo, I only have a working copy of the Apache repo
(since I hope my files will be incorporated there, see
https://issues.apache.org/jira/browse/CLI-173).  Does that fit the line
‘You must cause any modified files to carry prominent notices stating
that You changed the files;’?  I am not totally sure since it doesn’t
speak of “source form” explicitly.  Or should I include a line in the
NOTICE file claiming that I edited some files (and which?), or maybe
somewhere else?

Hm, sorry, this has gotten a bit chaotic now.  Feel free to ask for
