LGTM, I'll let Anton Parkhomenko (@chuwy) have a second look

[Anton Parkhomenko (chuwy)]

Thank you so much Julio Carlos Menendez (@juliomenendez). That totally makes sense. I'd actually go further and make emiiters a package with separate celery_emitter module to not confuse people who don't use celery, but this is also a good solution for now.

[Julio Carlos Menendez (juliomenendez)]

Thanks! What should I do about the tests failing for Python 3.3? Remove that version entirely maybe?

[Anton Parkhomenko (chuwy)]

Good question. For me Python 3.3 doesn't look outdated yet. Let's wait until we have a bandwidth for a new release and we'll decide what to do with 3.3 then.

Also, it looks like problem not in tracker, but in other our project - release-manager, which is a bit suspicious. Maybe we can stick with earlier version (e.g. 0.2.0)
