@chapter Overview about @command{texi2html}
@uref{http://www.texinfo.org,Texinfo} is the official
documentation format of the @uref{http://www.gnu.org,GNU}
project. It uses a single source file to produce both
online information and printed output.

@c much thinking about ...
It is often proposed to have a way to produce
@acronym{HTML} from Texinfo sources, like the GNU-Info
format. It is much simpler to create one converter instead
of writing all documentation new in @acronym{HTML}, cause
there is so much documentation in Texinfo all over
the world.

A few time ago @command{makeinfo} wasn't able to produce
@acronym{HTML} output format, but there are needth to have
@acronym{HTML}. This was the borning hour for
@command{texi2html}. The basic purpose of @file{texi2html}
is to convert Texinfo documents into HTML.

@node HowToGetHTML, whytexi2html, Overview, Overview
@section Ways to get HTML
You would like to @acronym{HTML} files out of your Texinfo
files? There exist two ways which you can go.
This first is to use @command{makeinfo} itself to produce
@acronym{HTML} output. The second is to use
@command{texi2html}.

@c --------------------------------------------------------
@node whytexi2html, Installation, HowToGetHTML, Overview
@section Why @file{texi2html} and not @file{makeinfo}?
The basic idea of @command{makeinfo}'s @acronym{HTML}
output was to get an readable @acronym{HTML} output.
Nothing sophisticated nor good styling just readable.

The current development of texi2html is going into
different direction.

The main purpose is to get better styling, better design
etc. of the created @acronym{HTML} pages. This way is
supported using differnt command line options and of course
possible changings of the initialization file to fit your
own needs.

The main disadvantage of @acronym{makeinfo}'s
@acronym{HTML} output is your getting only one big file.
This is of course readable but not very usable. The problem
of this is, while you like to have splitted chapters or
nodes the Texinfo source has to be read at minimum twice
times. This makes it impossible to implement this in
@command{makeinfo}. This would result in complete new
implementation of @command{makeinfo}'s source.

@c think more about this????
In contrast to the HTML produced by @command{makeinfo
--html} (the @command{makeinfo} program is part of the
Texinfo distribution), the HTML output of @file{texi2html}
is highly configurable. Among other differences, with
@command{texi2html} allows you to customize your entire
page layout (like headers, footers, style sheets, etc),
split documents at various levels, and use
@command{latex2html} to convert @code{@@tex} sections.

@command{texi2html} should reasonably convert all Texinfo
4.0 constructs. If not, please send a bug report to
@email{texi2html@@mathematik.uni-kl.de}.
