.SH NAME
weave \- translate WEB to TeX
.SH SYNOPSIS
.PP
\f[B]weave\f[R] [\f[B]-x\f[R]]
\f[I]webfile\f[R][\f[B].web\f[R]]
[{\f[I]changefile\f[R][\f[B].ch\f[R]]|\f[B]-\f[R]}
[\f[I]outfile\f[R][\f[B].tex\f[R]]]]
.\"=====================================================================
.SH DESCRIPTION
This manual page is not meant to be exhaustive. The complete
documentation for this version of \*(TX can be found in the info file
or manual
.IR "Web2C: A TeX implementation" .
.PP
The
.B weave
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 that it gathers automatically.
The command line arguments are the same as for
.B tangle
except for the option:
.B \-x
says to omit the index, 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 or from the third argument.
In this case you can specify '-' as an empty change file.
.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.
.\"=====================================================================
.SH FILES
.TP \w'@@'u+2n

output.
