Hello,

cweave which version is CWEAVE 4.7 (TeX Live 2022) doesn't work for
https://www-cs-faculty.stanford.edu/~knuth/programs/ssxc0.w file.

After cweave, doing tex has the following error message

This is TeX, Version 3.141592653 (TeX Live 2022) (preloaded format=tex)
(./ssxc0.tex (/usr/local/texlive/2022/texmf-dist/tex/plain/cweb/cwebmac.tex
(/usr/local/texlive/2022/texmf-dist/tex/generic/iftex/iftex.sty)) *1

?

but Knuth's original cweb(ftp://ftp.cs.stanford.edu/pub/cweb/cweb.tar.gz) works fine.

Thank you.

Fix issues #61, #62, and #64; clarify issue #63.

Use iftex.sty to test for TeX engine.

'$' is permitted in C identifiers (CTANGLE).
Add option '+u' for CTANGLE (poor man's UTF-8 transliteration).

Improve PDF validation, following advice from 3-Height PDF Validator.
NOS has 'count \I' subentries.
