I wouldn't exactly call it source code.

It's more like a book with extensive description containing all the source code.. without much structuring.

Somehow it hurts.

.. then again, maybe the dvi/pdf version I saw just missed that. Not very experienced with TeX, but I guess the output can be rendered nicely. Why did you post the TeX source edition of a book?

It's both the source code and a book. This single source file can be compiled to both the book (weave->tex->dvi2ps) or too Tex itself (tangle->pascal compiler). It's kind of a beautiful idea I think. I would strongly recommend getting the printed book form (very cheap second hand on Amazon) as it's a fascinating read.

It's also the source of the TEX language but written in a "Literate" style that Knuth pioneered.

I just thought it was pretty interesting while reading Coders at Work since a lot of people refer to it.
