That's might be true for bwk's and Pike's stuff, but not Rich Steven's or
Comer's books.   I know for fact that Rich had a set of macro's (based
originally on -ms) and a set of integrated makefiles to build his texts.  I
was under the impression he passed them to a number of people, not just
people like me.
