As a nascent user of HyperCard, I understand that I can attach
sound resources (SND's?) to the stacks and to HyperCard itself
to get more sounds.  I can also put them (somehow?) into my
system folder to get a fuller, richer, more satisfying beep or bong.
However, I don't know how to do this, where they come from, what
a CheapBeep is, and so on.  Could some kind soul post a brief
(or not so brief--it's only a world's worth of phone calls) tutorial
on sound, its construction, and use.  Definitions of resources,
brief descriptions of tools and their availability, and such like
would be very helpful.  I suspect that I am not the only mystified
person out here.
