Happy New Year!

Starting from the project https://github.com/ascherer/twill and by 
comparing the working TWILL.WEB 2.9 with WEAVE.WEB 4.5, I was able to 
create a change-file WEAV-TWILL.CH in https://github.com/ascherer/web 
that can be TIEd together with WEB-FPC.CH, WEAV-PATCH.CH, AND 
WEAV-SQUASH,CH into a single change-file TWILL.CH that mogrifies 
WEAVE.WEB into a working TWILL.WEB 4.5.

If you clone https://github.com/ascherer/web and have the Free Pascal 
Compiler installed, you can simply say 'make boot cautiously all PDF=pdf 
fullmanual' to get a modern 'twill' executable (and the readable source 
in 'twill.pdf') that works with the accompanying TWIMAC.TEX.

ATTOW, I have not studied TWILL enough to fully understand the process 
and the available features, so as DEK said in 1987: "you probably 
shouldn't try....", although it seems to be quite promising AS IS. After 
invoking './twill weave.web twill.ch twill.tex' twice, you have to 
resolve several '\none' entries in the mini-indexes with 'sed -i 
twill.tex -e "s/\\\\none/=42/"' before you can invoke 'tex twill.tex' twice.
