Sorry, I didn't mean to say that any of _your_ tools or libraries are 
non-free licensed - only the spec files you publish.

Ah, so it exists, just well hidden.

Yes, please do provide your specs (also the earlier 0-8 one) as XML.

As I wrote in my P.S. I believe to have those specs prepared for you 
already - just needs proof-reading and formal hand-over (from your side 
only: I need no credit, but your license doesn't allow my editing so you 
need to permit me that explicitly, I believe).

Now that I inspected more closely it turns out that only a single 
package - qpid-python - is in violation - and then not your derived 
specs but original ones.

I now filed [bug#706101] - after you posted above, so no wonder you 
couldn't find it - if you tried :-).

Even if not so serious after all, still relevant for my needs: The Perl 
module [AnyEvent::RabbitMQ] ships with your published XML.  I will get 
in touch with the author and suggest using your JSON instead...


Thanks for your swift reply,

 - Jonas
