DESCRIÇÃO
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... Texi2html may furthermore use latex2html to generate HTML (code and/or images) for @math and @iftex tags (see the --l2h option). Texi2html creates several files depending on the contents of the Tex‐ info file and on the chosen options (see FILES). The HTML files created by texi2html are in general closer to TeX than to Info. Using init files (see the --init-file option), other styles or output formats may be selected.
