In a thesis on another topic :-), I need to cite Knuth's
"literate programming" system (developed for the writing of \TeX).
Unfortunately library searches are rather awkward for me at present.
Can anyone provide a reference to Knuth's original "literate programming"
paper, and ideally to a recent survey/review paper as well?  (Ideally
a full citation, including paper title, journal, volume and issue
numbers, starting and ending page numbers.)  E-mail replies are
probably best; the connection to \TeX{} is tenuous already.  I'll
summarize for the newsgroup in the (unlikely) event there's a demand.

Thanks $1.0 \times 10^6$,
