NAME

       twill - translate WEB to TeX

SYNOPSIS

       twill [-x] webfile[.web] [{changefile[.ch]|-} [outfile[.tex]]]

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 tangle except for 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.  And, to cause output of only changed
       modules, one can say \let\maybe=\iffalse (usually as the first change in the change file).

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

       $TEXMFMAIN/tex/plain/knuth-lib/twimac-web.tex
           TeX macros used by twill output.
