Ocarina 6.2 is the 6th implementation of the Ocarina music player - a
lightweight, GTK+ based music player with all the features that I want.
Improvements over the 5.x series will include the existence of both a design
document (this file) and unit tests.  This should make maintenance easier and
help me stay focused.

Ocarina 6.2 will use Gstreamer 1.0 for audio playback, GTK-MM 3 for user
interface development, and Taglib for extracting tags.



Install:
	Ocarina will be compiled into a single executable placed under
	/usr/bin/.  Any extra files needed to run will be placed under
	/usr/share/ocarina/.


Core Layers:
	Ocarina was written with an "every file is a layer" strategy.  This
	means code can only call functions that reside in a lower layer.
	From top to bottom, core layers are:

		* Audio		(include/core/audio.h)
		* Audio driver	(include/core/driver.h)
		* Deck		(include/core/deck.h)
		* Playlist	(include/core/playlist.h)
		* Library	(include/core/library.h)
		* Queue		(include/core/queue.h)
		* RNG		(include/core/random.h)
		* Tags		(include/core/tags/*.h)
		* Idle queue	(include/core/idle.h)
		* Filter	(include/core/filter.h)
		* Index		(include/core/index.h)
		* Databases	(include/core/database.h)
		* File		(include/core/file.h)
		* Callbacks	(include/core/callback.h)
		* Version	(include/core/version.h)
