I guess I'll have to get the book about
Generative Programming
(by
Krzysztof Czarnecki and
Ulrich Eisenecker).
To me, it appears closely related to
many of the more interesting recent directions
in programming productivity research.
Unfortunately, they're both currently available only in the rather
archaic and inaccessible postscript format. Do Unix guys realize
that this format has become so much less accessible to the rest
of the world than PDF?
