---------------------------
Added
*****
``switchio`` is a hard fork of Sangoma's `switchy`_ project which seeks
to leverage features in modern Python (3.5+) including the language's
new native `coroutine` syntax and supporting event loop backend(s) such
as the standard library's `asyncio`_. The change history prior to
this fork can be found in the original projects's log. Python 2.7
support will be dropped likely for the first non-alpha release.

- Full (self-contained) CI using a production FreeSWITCH ``docker`` image
and runs on ``TravisCI``.
- ESL inbound protocol implementation written in pure Python using an
``asyncio.Protocol``.
- Event loop core rewritten to support Python 3.5 coroutines and `asyncio`_
engine.
- Coroutine app support using a ``coroutine`` decorator and an extended
``Session`` API which allows for awaiting particular (sets) of events.

- Legacy IVR example(s)
