[texhax] Per-page indices in weave output?

[Karl Berry]

Hi Stephen (nice to meet you oh-so-recently :),

I believe the mini-indexes are produced by a program called twill
(ctwill for CWEB), though I'm not finding the code anywhere.  Knuth
wrote a paper about it which is in the Digital Typography book, I
believe, and here's a random PDF of it that Google told me about:

I think we just learned at the panel that those mini-indexes (or maybe
the initial implementation?) were Joe Weening's idea.  And that the
final printed output was not generated completely automatically, but was
hand-tuned by DEK (no surprise there).

Happy hunting,
Karl
