.TH TEXI2HTML 1 "01/05/98"
Initial creation of sourceware repository
1999-04-16 03:34:55 +02:00
.AT 3
.SH NAME
texi2html \- a Texinfo to HTML converter
.SH SYNOPSIS
.B texi2html [options] file
.PP
.B texi2html -check [-verbose] files
.SH DESCRIPTION
.I Texi2html
converts the given Texinfo file to a set of HTML files. It tries to handle
most of the Texinfo commands. It creates hypertext links for cross-references,
footnotes...
.PP
It also tries to add links from a reference to its corresponding entry in the
bibliography (if any). It may also handle a glossary (see the
.B \-glossary
option).
.PP
.I Texi2html
creates several files depending on the contents of the Texinfo file and on
the chosen options (see FILES).
.PP
The HTML files created by
.I texi2html
are closer to TeX than to Info, that's why
.I texi2html
converts @iftex sections and not @ifinfo ones by default. You can reverse
this with the \-expandinfo option.
.SH OPTIONS
.TP 12
.B \-check
Check the given file and give the list of all things that may be Texinfo commands.
This may be used to check the output of
.I texi2html
to find the Texinfo commands that have been left in the HTML file.
.TP
.B \-expandinfo
Expand @ifinfo sections, not @iftex ones.
.TP
.B \-glossary
Use the section named 'Glossary' to build a list of terms and put links in the HTML
document from each term toward its definition.
.TP
.B \-invisible \fIname\fP
import gdb-1999-08-02 snapshot
1999-08-03 01:48:02 +02:00
Use \fIname\fP to create invisible destination anchors for index links
(you can for instance use the invisible.xbm file shipped with this program).
This is a workaround for a known bug of many WWW browsers, including netscape.
Initial creation of sourceware repository
1999-04-16 03:34:55 +02:00
.TP
.B \-I \fIdir\fP
Look also in \fIdir\fP to find included files.
.TP
.B \-menu
Show the Texinfo menus; by default they are ignored.
.TP
.B \-monolithic
Output only one file, including the table of contents and footnotes.
.TP
.B \-number
Number the sections.
.TP
.B \-split_chapter
Split the output into several HTML files (one per main section:
chapter, appendix...).
.TP
.B \-split_node
Split the output into several HTML files (one per node).
.TP
.B \-usage
Print usage instructions, listing the current available command-line options.
.TP
.B \-verbose
Give a verbose output. Can be used with the
.B \-check
option.
.PP
.SH FILES
By default
.I texi2html
creates the following files (foo being the name of the Texinfo file):
.TP 16
.B foo_toc.html
The table of contents.
.TP
.B foo.html
The document's contents.
.TP
.B foo_foot.html
The footnotes (if any).
.PP
When used with the
.B \-split
option, it creates several files (one per chapter or node), named
.B foo_n.html
(n being the indice of the chapter or node), instead of the single
.B foo.html
file.
.PP
When used with the
.B \-monolithic
option, it creates only one file:
.B foo.html
.SH VARIABLES
.I texi2html
predefines the following variables: \fBhtml\fP, \fBtexi2html\fP.
.SH ADDITIONAL COMMANDS
.I texi2html
import gdb-1999-08-02 snapshot
1999-08-03 01:48:02 +02:00
implements the following non-Texinfo commands (maybe they are in Texinfo now...):
