STsndplay is a program for playing all those old Atari tunes without the need
for an actual Atari to play them.

Those who have been following will notice that this is exactly the same
description as PSGPlay has. The concept is somewhat different though.

PSGPlay plays raw PSG data, which has been prepared in a somewhat messy format.
STsndplay uses a different approach (and different song files), by instead
emulating the Motorola 68000 CPU, and play the songs using the original Atari
playback routine. The benefit from this is that I do not need specifications of
the audio format, because the player already knows how to play it.
