Quoting from the back of my ImageStudio manual,

"The RIFF specification is available from Letraset USA at 40 Eisenhower
Drive, Paramus, NJ 07652.  The specification is also available through
AppleLink, CompuServe, and GEnie."

I phoned Letraset USA <+1 201 845 6100> a while back and received back
a free disk containing MPW C and Lightspeed C (2.01? if I remember
correctly) source for parsing RIFF files, along with pertinent
documentation files.  There is at least one typo in the documentation
and I remember having to make a few changes to get the LSC code running
efficiently under LSC 3, but there weren't any major problems.

I profiled and re-coded parts of the RIFF input routines in assembler
and sped them up by the usual 3x or so.  If you want diffs to the
relevant file[s], send me mail.

John
