MacDraw can save its files in either DRWG or PICT format.  How can
I determine, by inspecting the bytes of the data fork, which
format a particular file is in?  I checked in Tech Notes 21 and 27,
and I suspect that the answer is that I can't.  The 512 byte headers
are exactly the same in some (all?) cases, and the data doesn't seem
to have a lot of clues.  Oh well, I guess I'll have to try looking
for the .info part of the file (I'm doing this on UNIX you see...).

Thanks for any advice you can offer.
