sure.  but if your purpose is understanding tex, reading knuth's sources
is not a way i would recommend.  (the texbook is quite hard going, in
places, and reading code describing something difficult may be worse
still.  note that ymmv, but i struggled in the 80s having never used
anything more complex than digital runoff.)

i agree, it's a shame a-w (or whatever they're called now) can't bring
themselves to offer an e-book version.
