+.SH NAME
+twill \- translate WEB to TeX
+.SH SYNOPSIS
+.B twill
+.RB [ \-x ]
+.IR webfile [ \fB.web\fP ]
+.RI [ changefile [ \fB.ch\fP ]]
+.\"=====================================================================
+.SH DESCRIPTION
+The
+.B twill
+program is used to create a \*(TX file for viewing a \*(WB 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.
+.PP
+The command line arguments are the same as for
+.B tangle
+except for the option:
+.B \-x
+says to omit the indexes, module name list, and table of contents pages.
+(A
+.I CONTENTS.tex
+file will still be written when the \*(TX file is processed,
+however, unless some macros in
+.I webmac.tex
+are redefined.)
+.PP
+The output \*(TX file name is formed by adding
+.B .tex
+to the root of the \*(WB file name.
+.PP
+There are several macros
+that probably should be redefined by
+the programmer at the beginning of the \*(WB 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).
+.\"=====================================================================
+.SH ENVIRONMENT
+The environment variable WEBINPUTS is used to search for the input files,
+or the system default if WEBINPUTS is not set.  See
+.BR tex (1)
+for the details of the searching.
