So you own the _former_ ones.

You can get those two books (modulo per-page indexes and maybe a
preface, don't remember) by running

weave tex.web
weave metafont.web
tex tex
tex metafont
dvips tex
dvips metafont

I really recommend that you do this (tex.web and metafont.web should
be available with your TeX distribution, but they are of course also
available on every TeX server).

That will both give you an excellent example of what you are talking
about as well as show you the limitations of that approach.

No need to guess.  Please check the above out.  It will make the
discussion so much more worthwhile.  And it definitely provides good
reading, anyway.

Can we agree that TeX is not a very small project?
