For the benefit of those who +may not be able to ftp these files easily, this message contains some +of the more important details: + + New files at labrea since 3 January 91 + Changes to the errata list (ERRATA.SIX) + Addenda to TeX82.BUG as of 13 March 91 + Addenda to MF84.BUG as of 13 March 91 + Differences between TeX.WEB 3.1 and 3.14 (as of 18 March 1991) + Differences between TeX.WEB 3.0 and 3.1 (as of 21 September 1990) + Differences between MF.WEB 2.0 and MF.WEB 2.7 (as of 13 March 1991) + Cosmetic change, GFTODVI.WEB, ver 3.0 + +Differences in TeX.WEB are provided in two parts since the details of the +update from version 3.0 to 3.1 was never reported in one of these messages. +In fact, both TeX.WEB and MF.WEB have been updated twice, with only one +version change, since the previous update. The most recent changes were, +as Don Knuth says in the prose at the top, only cosmetic; cosmetic changes +do not usually appear in the bug listings, but should generally be made to +the main WEB files anyhow in order to keep in synch. + +This is the last time that it will be possible to provide the difference +listings in this form. These difference listings were prepared with a +TOPS-20 utility, and the Math Society's DEC-20 is being unplugged and +de-installed tomorrow. We now have a couple of Unix workstations, and +the Unix differencing utility seems to be the best replacement (as soon +as I learn how to use it). Although the VAX/VMS DIFF utility does a good +job of identifying differences, it adds a line number to each difference +line, often resulting in lines of more than 80 characters in length; not +a robust format for sending in e-mail across random network gateways. + +As usual, there have been a number of updates to this mailing list since +the last time I sent a message directly, so if everyone receiving this +message could please acknowledge it, that will help keep the list in +good shape. + + +######################################################################## + +New files at labrea.stanford.edu since 3 Jan 91 + +/tex: +-rw-r--r-- 1 468 fsuser 52165 Mar 13 17:03 DIFFS.Mar91 +-rw-r--r-- 1 468 fsuser 0 Mar 13 17:24 tex.log + +/tex/OLD.pre-Mar91: +total 7 +drwxr-xr-x 2 468 fsuser 512 Mar 13 17:14 cweb +drwxr-xr-x 2 468 fsuser 512 Mar 13 17:19 errata +drwxr-xr-x 6 468 fsuser 512 Mar 13 17:14 local +drwxr-xr-x 2 468 fsuser 512 Mar 13 17:18 mf +drwxr-xr-x 2 468 fsuser 512 Mar 13 17:16 mfware +drwxr-xr-x 2 468 fsuser 512 Mar 13 17:18 tex +drwxr-xr-x 2 468 fsuser 512 Mar 13 17:14 tugboat + +/tex/bibtex: +-rw-rw-r-- 1 weening ftp 27577 Mar 15 15:45 btxmac.tex + +/tex/errata: +-rw-rw-rw- 1 468 fsuser 15838 Mar 15 21:40 errata.six +-rw-r--r-- 1 468 fsuser 2528 Mar 13 17:05 errata.tex +-rw-r--r-- 1 468 fsuser 79228 Mar 13 17:05 mf84.bug +-rw-r--r-- 1 468 fsuser 295236 Mar 13 17:05 tex82.bug + +/tex/latex: +-rw-rw-r-- 1 root ftp 15834 Jan 14 18:58 addendum.tex +-r--r--r-- 1 root fsuser 40243 Feb 8 21:02 latex.bug +-r--r--r-- 1 root fsuser 286412 Feb 8 21:02 latex.tex +-r--r--r-- 1 root fsuser 48458 Feb 8 21:02 lplain.tex +-r--r--r-- 1 root fsuser 48804 Feb 8 21:03 splain.tex + +/tex/local/cm: +-rw-rw-rw- 1 468 fsuser 3561 Mar 15 21:44 ccmic9.mf +-rw-rw-rw- 1 468 fsuser 217 Mar 15 21:44 odigs.mf + +/tex/local/lib: +-rw-r--r-- 1 468 fsuser 3133 Mar 13 17:08 art.mf +-rw-rw-r-- 1 468 fsuser 33699 Mar 13 17:09 gkpmac.tex +-rw-r--r-- 1 468 fsuser 1581 Mar 13 17:09 list.tex +-rw-r--r-- 1 468 fsuser 2179 Mar 13 17:09 llist.tex +-rw-r--r-- 1 468 fsuser 263 Mar 13 17:09 oneone.mf +-rw-r--r-- 1 468 fsuser 8240 Mar 13 17:09 picmac.tex + +/tex/local/mf: +-rw-r--r-- 1 468 fsuser 691 Mar 13 17:09 plain.log + +/tex/local:/tex/local/mfware: +-rw-r--r-- 1 468 fsuser 28547 Mar 13 17:10 gftodvi.ch + +/tex/local/tex: +-rw-r--r-- 1 468 fsuser 53657 Mar 13 17:10 initex.ch + +/tex/mf: +-rw-r--r-- 1 468 fsuser 916840 Mar 13 17:06 mf.web +-rw-r--r-- 1 468 fsuser 938679 Mar 13 17:06 mfbook.tex +-rw-r--r-- 1 468 fsuser 18238 Mar 5 23:56 trapman.tex + +/tex/mfware: +-rw-r--r-- 1 468 fsuser 186545 Mar 13 17:06 gftodvi.web + +/tex/tex: +-rw-r--r-- 1 468 fsuser 1025435 Mar 18 21:20 tex.web +-rw-r--r-- 1 468 fsuser 1381907 Mar 13 17:07 texbook.tex +-rw-r--r-- 1 468 fsuser 2438 Mar 13 17:07 trip.fot +-rw-r--r-- 1 468 fsuser 182701 Mar 13 17:07 trip.log +-rw-r--r-- 1 468 fsuser 18025 Mar 13 17:07 trip.typ +-rw-r--r-- 1 468 fsuser 12930 Mar 13 17:08 tripin.log + +/tex/tugboat: +-rw-r--r-- 1 468 fsuser 30903 Mar 11 19:44 guidepro.tex +-rw-r--r-- 1 468 fsuser 14810 Mar 11 19:44 ltugboat.sty +-rw-r--r-- 1 468 fsuser 3785 Mar 11 19:44 ltugproc.sty +-rw-r--r-- 1 468 fsuser 25567 Mar 11 19:44 tugboat.com +-rw-r--r-- 1 468 fsuser 66791 Mar 11 19:44 tugboat.sty +-rw-r--r-- 1 468 fsuser 8901 Mar 11 19:44 tugproc.sty + + +######################################################################## + +Addenda to TeX82.BUG as of 13 March 91 + +------------- +Note: When making change 376, I forgot to delete the redundant +code in module 883, and I should also have changed the name of that +module.
