     "Texinfo is the official documentation format of the GNU project.  It
uses a single source file using explicit commands to produce a final document
in any of several supported output formats, such as HTML or PDF.  This
package includes both the tools necessary to produce Info documents from
their source and the command-line Info reader.  The emphasis of the language
is on expressing the content semantically, avoiding physical markup commands.")

    (synopsis "Convert Texinfo to HTML")
    (description
     "Texi2HTML is a Perl script which converts Texinfo source files to HTML
output.  It now supports many advanced features, such as internationalization
and extremely configurable output formats.

Development of Texi2HTML moved to the GNU Texinfo repository in 2010, since it
was meant to replace the makeinfo implementation in GNU Texinfo.  The route
forward for authors is, in most cases, to alter manuals and build processes as
necessary to use the new features of the makeinfo/texi2any implementation of
GNU Texinfo.  The Texi2HTML maintainers (one of whom is the principal author
of the GNU Texinfo implementation) do not intend to make further releases of
Texi2HTML.")
