    Does anyone have any information on the PostScript file format
    used by Adobe Illustrator?
    
    I have looked at some sample Illustrator files, but deducing the
    type of PostScript that Illustrator will swallow from a few sample
    files is not a trivial task.

The format Illustrator uses is just plain PostScript.  However, there
is a library that must first be loaded in order to interpret the
Illustrator output correctly.

You can get a copy of the library by printing a simple Illustrator
document and capturing the PostScript output to disk with the backdoor
F key trick.  Then just clip off everything at the end of the file
that relates to your specific document.  Voila.  Notice that saved
files are _identical_ to PostScript printing dumps minus the header
code.

Once you have the header, you can read it to find out what each one or
two-letter abbreviation does.  The Illustrator library is much more
readable than Apple's Laser Prep file, but still this is a non-trivial
undertaking.

Good luck!
