Introduction
************

   The idea behind OpenAL is a 3d positional spatialized sound library
analogous to OpenGL: instead of micromanaging each aspect of sound
playback and effect, the application writer may limit themselves to
placing the sounds in the scene and letting the native OpenAL
implementation determine the correct amount of pitch alteration, gain
attenuation, phase shift, etc, required to render the sounds correctly.

   That's the goal, anyway.
