-.TH TEXI2HTML 1 "09/10/96"
-.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
-Use \fIname\fP to create invisible destination anchors for index links. This is a workaround
-for a known bug of many WWW browsers, including xmosaic.
-.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
-implements the following non-Texinfo commands:
-.TP 16
-.B @ifhtml
-This indicates the start of an HTML section, this section will passed through
-without any modofication.
-.TP
-.B @end ifhtml
-This indcates the end of an HTML section.
-.SH VERSION
-This is \fItexi2html\fP version 1.51, 09/10/96.
-.PP
-The latest version of \fItexi2html\fP can be found in WWW, cf. URL
-http://wwwcn.cern.ch/dci/texi2html/
