You know those boxes at the bottom of the right-hand pages in Volume B? Well, I managed to weave mf.web by stealing the weave binary from a distribution where it actually works (it doesn't in MiKTeX), and it TeXed fine, but I'm at a bit of a loss as to why those boxes haven't appeared. Is there any way I can get them, or are does Knuth keep the code for that locked up?

the "mini-index" listings in volume b were generated separately and added in post-processing. there is a chapter in knuth's book "digital typography" entitled "mini-indexes for literate programs" (it's chapter 11, pp.225-245), as well as several other entries in the index.

a program TWILL was used to create the mini-indexes in both volumes b and d. the name was "suggested by the fact that it was a two-pass variant of the standard program called WEAVE." there were several references to TWILL in the course of the panel discussion at tug 2010. (see http://tug.org/TUGboat/tb31-2/tb98panel.pdf or the video of the panel at http://river-valley.zeeba.tv/tug-2010-panel/) apparently TWILL is somewhere on knuth's web site (http://www-cs-faculty.stanford.edu/~knuth/), . "It's not that easy to use, so I don't advertise it much. It requires running in several passes."

so it is out there to be explored, if not that easy to use.

Hmm, looks like someone asked the same question not too long ago on TeXhax: comments.gmane.org/gmane.comp.tex.texhax/13687; unfortunately I'm not seeing any sign of TWILL itself -- I hope I don't have to write a letter to Knuth and wait until he reads it in 2014 before I can learn the URL! – SamB Feb 5 '11 at 0:13
I've found a SO question about CTWILL (answered it, too!), and a tape listing that contains an entry for TWILL.WEB and one for TWILL.CH... – SamB Feb 5 '11 at 1:21
... and score! here I can actually get to the files: saildart.org/prog/SYS/TEX_SYS/.browser.html – SamB Feb 5 '11 at 1:24
