	AppleSingle and AppleDouble are ways of encoding Apple's irregular
file info (including forks) on a more standard filesystem. Basically, they're
just wrappers including the file's real name (so, if you wanted to stick
"Jason's Misc Stuff" from a HFS disk onto a MS-DOS disk, you wouldn't have
a problem), it's type, auxtype, whatever. Anyways, AppleSingle can include
two forks in one file, whereas AppleDouble splits a forked file into two
separate files.

	I'm also almost positive that there are filetype notes on these,
with something like $e0/0000 and $e0/0001 (?). You can get those from
apple.com.

	Who cares? It just needs to exist...

	It'd be nice - you'd have to make your data structures dynamic,
but I don't think it'd make coding any harder...

>(hoh hoh.. guess what I'm up to? :-)

	Gee, whatever in the world? Whatever it is, I'd be interested in
seeing early versions of it...
