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 -(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. -.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 (maybe they are in Texinfo now...): -.TP 16 -.B @ifhtml -This indicates the start of an HTML section, this section will passed through -without any modification. -.TP -.B @end ifhtml -This indicates the end of an HTML section. -.SH VERSION -This is \fItexi2html\fP version 1.56k, 1999-02-20. -.PP -The latest version of \fItexi2html\fP can be found in WWW, cf. URLs -http://wwwinfo.cern.ch/dis/texi2html/ -.br -http://texinfo.org/texi2html/ -.SH AUTHOR -The main author is Lionel Cons, CERN IT/DIS/OSE, Lionel.Cons@cern.ch. -Many other people around the net contributed to this program. -.SH COPYRIGHT -This program is the intellectual property of the European -Laboratory for Particle Physics (known as CERN).
