NAME

6       twill - translate WEB to TeX
7

SYNOPSIS

9       twill [-x] webfile[.web] [changefile[.ch]]
10

DESCRIPTION

12       The  twill  program is used to create a TeX file for viewing a Web pro‐
13       gram.  It takes appropriate care of typographic details like page  lay‐
14       out  and  the  use of indentation, italics, boldface, etc., and it sup‐
15       plies extensive cross-index information in the form  of  'mini-indexes'
16       for  each spread of pages and a 'master index' at the end that it gath‐
17       ers automatically.
18
19       The command line arguments are the same as for tangle  except  for  the
20       option:  -x  says  to  omit the indexes, module name list, and table of
21       contents pages.  (A CONTENTS.tex file will still be  written  when  the
22       TeX  file  is  processed, however, unless some macros in webmac.tex are
23       redefined.)
24
25       The output TeX file name is formed by adding .tex to the  root  of  the
26       Web file name.
27
28       There  are several macros that probably should be redefined by the pro‐
29       grammer at the beginning of the Web file.  It is a  good  idea  to  set
30       \title  to  the  name  of  the  program.   And, to cause output of only
31       changed modules, one can say \let\maybe=\iffalse (usually as the  first
32       change in the change file).
33

ENVIRONMENT

35       The  environment  variable  WEBINPUTS  is  used to search for the input
36       files, or the system default if WEBINPUTS is not set.  See  tex(1)  for
37       the details of the searching.
