NAME
twill, twill-refsort - translate Web to TeX with mini-indexes
SYNOPSIS
twill [-x] webfile[.web] [{changefile[.ch]|-} [outfile[.tex]]]
twill-refsort < reffile.ref > sreffile.sref
DESCRIPTION
The twill program is used to create a TeX file for viewing a Web
program. It takes appropriate care of typographic details like page
layout and the use of indentation, italics, boldface, etc., and it
supplies extensive cross-index information in the form of 'mini-
indexes' for each spread of pages and a 'master index' at the end that
it gathers automatically.
The command line arguments are the same as for weave including the
option: -x says to omit the indexes, module name list, and table of
contents pages. (A CONTENTS.tex file will still be written when the
TeX file is processed, however, unless some macros in twimac-web.tex
are redefined.)
The output TeX file name is formed by adding .tex to the root of the
Web file name.
There are several macros that probably should be redefined by the
programmer at the beginning of the Web file. It is a good idea to set
\title to the name of the program.
twill is exactly like weave except that it produces better
documentation, for which you must work harder. You should run twill
twice, once to prime the pump and once to get decent answers.
Moreover, you must run the output twice through TeX.
After tex foo you will have output that looks like final pages except
that the entries of mini-indexes won't be alphabetized. The first run
produces a weird file called foo.ref. Say twill-refsort < foo.ref >
foo.sref and then another tex foo will produce alphabetized output.
ENVIRONMENT
The environment variable WEBINPUTS is used to search for the input
files, or the system default if WEBINPUTS is not set. See tex(1) for
the details of the searching.
FILES
