eps scripting reference guide...anyone...please?

I am seeking any solid reference (article,website,book,anything!!!) that will explain the intricacies of the code that makes up an .eps file.

I have noticed that Illustrator puts a tremendous amount of seemingly uneccesary code in any .eps... even a blank one!

I downloaded an outdated PDF from adode resource area but its not comprehensive enough and its from 1992.

Basically, I need to manufacture .eps files with a piece of software I am designing. So essentially, I am writing a text file with instructions on how to render the .eps. The could have images, fonts, shapes.... etc just like an .eps created in Illustrator or some comprable program.

Thanks,
Joe
