-"""Asynchronous access to MPD using the asyncio methods of Python 3.

-Interaction happens over the mpd.asyncio.MPDClient class, whose connect and
-command methods are coroutines.
-
-Some commands (eg. listall) additionally support the asynchronous iteration
-(aiter, `async for`) interface; using it allows the library user to obtain
-items of result as soon as they arrive.
-
-The .idle() method works differently here: It is an asynchronous iterator that
-produces a list of changed subsystems whenever a new one is available. The
-MPDClient object automatically switches in and out of idle mode depending on
-which subsystems there is currently interest in.

-Command lists are currently not supported.
