[CWEB] New macros for HiTeX.
We re-use 'proofmac.tex' (for plain TeX only) and add the PDF/HINT
stuff from 'cwebmac.tex' to produce active links in CTWILL output,
where each section gets its own mini-index. Especially in connection
with HiTeX, this gives an interesting new output format.
Use 'ctwill +P +lpdf' to '\input pdfproofmac' in the first line.
These macros _do_ also work with pdftex and xetex (and probably
with plain TeX as well).
Example from MMIX:
$ tie -c mmotype-twill.ch mmotype.{w,ch} mmotype-mini.ch
[Remove the final change in mmotype-twill.ch, we want to create
a full index at the end.]
$ ctwill +P +lpdf mmotype mmotype-twill (twice)
$ hitex mmotype
$ proofsort mmotype.tex > mmotype-sorted.tex
$ mv mmotype-sorted.tex mmotype.tex
$ hitex mmotype
$ hintview mmotype.hnt
