6# Daniel Quinlan (quinlan@yggdrasil.com) -- IFF was designed by Electronic
7# Arts for file interchange.  It has also been used by Apple, SGI, and
8# especially Commodore-Amiga.
9#
10# IFF files begin with an 8 byte FORM header, followed by a 4 character
11# FORM type, which is followed by the first chunk in the FORM.
