Actually, the 0.3.x sound subsystem is gone in glutton; the src/sound
subdir there is obsolete. All sound comes from src/sfx, which is a complete
re-write (with much improved timing).

The new (and, to a lesser extent, the old) sound kernel are supposed to
be reasonably portable, so don't worry about this too much-- an SDL sound
driver will appear sooner or later anyway (assuming that _someone_ works
on FreeSCI sound, that is).

Nothing new in the last two months or so. We have OSS/OPL/2 working fine
(last time I checked, anyway, which was in January-- my test box died)
and ALSA with MT-32 MIDI output for Linux. The sound subsystem now
includes a mixer interface, with a default implementation (and an
approximation of a test suite), but the interaction between timing
mechanisms and PCM drivers needs a minor overhaul before pcm output
will work.
  (I gave a rough overview of these issues in a mail from Sept. 11,
in case you're interested.)

At one point, I actually tried to make it drag&drop-startable (drag an
SCI game directory on top of FreeSCI and it will work), but I couldn't
figure out how to get the data that was passed via drag and drop in OS X.
  If anyone knows how this works, it might be a nice and intuitive feature
to have here.
