Help!

Does anyone know the specs for GIF89a?  I wrote a multi-purpose file 
viewer (ARC, ZOO, ZIP, GIF, etc.) that extracts info from GIF files 
such as # of colors, resolution, # of images and data CRC.

It would work fine on GIF89a's -- I think -- if I just patched it to
not notice that GIF89a and GIF87a are different.  But before I go 
Rube Goldberg'ing the code, I'd like to know what's really different
in 89a.  The FRACTINT people were really hip on it because it provides
a documented, legal place for them to stick extra parameters.

But where can I find the specs for it?  I have an old file called
GIFSTF.DOC which outlines 87a.  Does such a beast exist for 89a, and
if so, where?  (Please don't say Compu$pend, as I no longer have an 
account there...)

Thanks!
