/*
	out123: simple program to stream data to an audio output device

	copyright 1995-2014 by the mpg123 project - free software under the terms of the LGPL 2.1
	see COPYING and AUTHORS files in distribution or http://mpg123.org
	initially written by Thomas Orgis (extracted from mpg123.c)

	This rips out anything dealing with MPEG decoding and playlist handling,
	reducing the functionality to what shall become part of libout123: Simple
	means to get mono/stereo audio to various output devices on various
	platforms. Since this is rather redundant to other approaches (portaudio,
	etc.), the justification stems from two points:

	1. It's code home-grown for mpg123, defining a feature set without resorting
	another build dependency. Throwing the code away would reduce what the mpg123
	code base offers by itself.

	2. It's feature set is a commonly-needed subset of what a full audio
	framework provides. It's what simple playback of mono/stereo data needs.
	Therefore, it has a chance to stay (be?) simple to use, explicitly hiding
	complexity.

	TODO: Decide if the buffer process should be part of it. Might be a good
	idea. It's specific to output and is something tricky to get going yourself.
