Due to licencing issues, this package is not suitable for Debian.
Below is a mail describing the situation and the threads that went
into researching it. I had no response to this from the diffutils
author, only from the jrcs author saying 'better use my code as it is
properly licenced'. That could still be done, but I have no need for
it any longer so will not be uploading this.

Subject: Re: Fw: Re: Origin/licencing of myersdiff java code
Thank you for your quick responses when I last asked about this. I had
some problems with actually packaging the code so it got stalled for a
while, but I have now sorted that out and it is ready to upload,
except that there still seems to me to be room for confusion over the
licencing.
The thread is copied below, where Juancarlos gives the history of the
relicensing from Apache-1.1 to LPGL-2.1, Dmitry says it came from
http://code.google.com/p/jrcs, and Juancarlos confirms that that
version is LGPL.
This all seems clear enough, but looking at that repo and the code
the myers files have revision IDs in 2003:
DiffException.java $Revision: 69 $ $Date: 2003-10-13
DiffNode.java $Revision: 60 $ $Date: 2003-05-10
etc
and an Apache 1.1 header in them.
The history at http://code.google.com/p/jrcs just says 'initial import
from what Juanca sent me', which was in 2010.
So are those 2003 files still apache licensed really, despite what
Dmitry said about the source? What year/date was the shift from Apache
to LGPL? After 2003?
On the other hand, the top-level files (Delta, DiffAlgorithm, Patch,
etc) do not have revision IDs, but do have Apache 2.0 headers, and are
just marked "Copyright 2010 Dmitry Naumenko (dm.naumenko@gmail.com)",
implying at least later work, and possibly later derivation, which
would fit with Dmitry saying they came from http://code.google.com/p/jrcs
If this is the case where did the Apache-2.0 licence come from? That
would just seem to be wrong as Dmitry can't just change this
clearly-derived LGPL code into Apache-2.0. Even if it came from the
earlier Apache 1.1 code I don't think he can update them dervied files
to Apache-2.0.
So. What I currently have for a copyright file is (going on the
headers in the files, and the original mail thread, but I don't think
it can be right) is:
--------------------------
Format: http://www.debian.org/doc/packaging-manuals/copyright-format/1.0/
Upstream-Name: java-diff-utils
Upstream-contact: Dmitry Naumenko <dm.naumenko@gmail.com>
Source: http://code.google.com/p/java-diff-utils/
Comment: Much of this code was derived from JRCS, written by Juancarlo Añez
<juancarlo.anez@gmail.com>, which was originally Apache-1.1 and later
relicenced to LGPL-2.1. This version was derived from the 2003.06 LGPL
vintage of JRCS at http://code.google.com/p/jrcs. Clarified in emails
from Juancarlo Añez and Dmitry Naumenko. This is inconsistent with
the headers provided by upstream at
http://code.google.com/p/java-diff-utils/

-------------------------
Do we think that that is right? If it is then at least the headers on the
diffutils/myers/* files should be changed to say LGPL-2.1.
I am not familiar enough with the codebase and time lines to work out
from the diffs and online repos, exactly when the code was split off.
But it does look like we have some inconsistency, or simply
wrongly-labelled files.
On reflection, and looking at the files, I think the real situation is
something more like:
---------------
Files: *
Copyright: Copyright 2010 Dmitry Naumenko <dm.naumenko@gmail.com> and
1999-2006(?) Juancarlo Añez <juancarlo.anez@gmail.com>
License: LGPL-2.1

License: Apache-1.1
Files: debian/*
Copyright: Copyright 2012 Wookey <wookey@debian.org>
License: LGPL-2.1
-------------
If that is the case then the Apache-2.0 headers all need changing to
LGPL-2.1
In practice I think it would be better if we could agree between us a
consistent licence for the whole thing, which I think should really be
LGPL-2.1, and Dmitry should change the headers on the code in the repo
to match the reality, (giving due credit to Juancarlo by leaving his
name in).
So, what do you both think? Is there any way the Apache 2.0 licence
can be correct? Is everyone happy with LGPL-2.1 throughout (or "2.1 or
later"?).
I'd like to get this unbunged so this can go in Debian, and hopefully
we don't actually have any disagreement, just some confusion, so it
can be sorted reasonably quickly (before I get distracted again for
another 6 months).
Comments and clarifications welcome.
