\label{sec:ovw}\index{overview}
\noindent 
This manual describes the \latextohtml{} translator which is
used to create Web pages from document source written for
the \LaTeX{} typesetting system, or simply containing \LaTeX{} commands.

\godown{quest0}\medskip
\noindent
To use \latextohtml{} to translate a file~\Meta{file}\texttt{.tex}
containing \LaTeX{} commands, simply type:
\begin{quote}
\texttt{latex2html} \Meta{file}\texttt{.tex} 
\end{quote}
\noindent
This will create a new directory called \Meta{file} which will contain 
the generated \texttt{HTML} files, some log files and possibly some images.

\medskip\godown{quest1}\label{quest0}\smallskip
\noindent
Basically the translator reads the source document and creates a linked
set of \texttt{HTML} pages, displaying the information it contains.
The \LaTeX{} commands and environments that are found are interpreted
either as ``markup'' instructions, or as macros expanding into more text 
or markup commands. 
Where such markup corresponds to the intended use for markup tags
in the \texttt{HTML} language, a direct translation is made.
If there is no natural way to present the information using simple text
embellished with \texttt{HTML} markup tags, then an image is generated, 
using \LaTeX{} itself to interpret the portion of code.

Of course this is a drastically over-simplified description of what
\latextohtml{} actually does. Many questions spring readily to mind.
The answers to these and the options available to handle
particular situations are discussed elsewhere in this manual.

\godown{quest2}\label{quest1}%
\begin{itemize}
\item \latexhtml
{\emph{What does ``natural way to present the information'' really mean? }}
{{\large What does ``natural way to present the information'' really mean? }}
\end{itemize}
\noindent
Text and paragraphing clearly should appear as such, whether printed
or on-screen. Different font sizes and styles such as ``bold-face''
or ``italic'' are generally rendered accordingly.
However, whereas \LaTeX{} has access to appropriate fonts for specialised
purposes such as mathematical symbols, these cannot be guaranteed to be
available with all Web-browsers. So for information requiring such things,
\latextohtml{} will generally resort to making an image,
using \LaTeX{} itself to typeset the material required for that image. 

\hyperref{The next page}{Section~}{}{features:ovw} contains a brief overview
of how \LaTeX's standard environments are handled within \latextohtml.
It also mentions some of the extra features that are available. \html{\\}%
In general \latextohtml{} attempts to use textual constructions to represent
the required information. Generation of an image is done only when there is
no adequate textual construction with the required version of \texttt{HTML},
or when specifically requested to do so.
Various extensions, to cope with the different \texttt{HTML} versions and
extra features, are discussed \hyperref{elsewhere}{in Section~}{}{sec:fea}.
That describes what to expect on the \texttt{HTML} pages, with little
or no changes required to the \LaTeX{} source.

Just as \LaTeX{} has various packages which can be used to present specific
types of information in appropriate ways, 
so is \latextohtml{} capable of handling the commands from many of these packages. 
See \hyperref{this table}{Table~}{}{styles} for a listing of those 
packages which currently have special support.

\godown{quest3}\label{quest2}%
\begin{itemize}
\item \latexhtml
{\emph{Some features of \texttt{HTML} have no direct counterpart in
a \LaTeX{} typeset document.\\Can such features be used with \latextohtml? }}
{{\large Some features of \texttt{HTML} have no direct counterpart in
a \LaTeX{} typeset document.\\Can such features be used with \latextohtml? }}
\end{itemize}
\noindent
Any effect currently available with any version of the \texttt{HTML} 
standard can be specified for a document processed by \latextohtml.
New \LaTeX{} commands are defined in the \fn{html.sty} package;
the features that these commands allow are the subject of
\hyperref{a whole section of}{Section~}{ in}{sec:hyp} this manual.
Some of the new commands provide improved strategies for effects 
already existing in \LaTeX; e.g. 
\htmlref{cross-references}{hyperref} and \htmlref{citations}{hypercite}.
To use these effectively requires only small changes to the \LaTeX{} source.

Other commands define new environments which are completely
ignored when processed by \LaTeX. 
Indeed the \htmlref{full scope}{HTMLtag} of \HTMLiii{} is available, 
using \LaTeX-like macros to help structure the source, 
reduce the tedium of repetitious use of tags, and ensure that
all appropriate tags are correctly closed.


\godown{quest4}\label{quest3}%
\begin{itemize}
\item \latexhtml
{\emph{What determines the amount of information that goes onto
a single \texttt{HTML} page?\\How are different pages linked? }}
{{\large What determines the amount of information that goes onto
a single \texttt{HTML} page?\\How are different pages linked? }}
\end{itemize}
\noindent
The \texttt{HTML} pages can contain whole chapters, sections,
(sub)subsections or (sub)paragraphs. This is fully customisable
using the command-line options discussed in detail in
\hyperref{a separate section}{Section~}{}{options} of this manual.


\godown{quest5}\label{quest4}%
\begin{itemize}
\item \latexhtml
{\emph{Does the original document have to be a valid \LaTeX{} document,
typesetting without errors? If not, does it help if it is? }}
{{\large Does the original document have to be a valid \LaTeX{} document,
typesetting without errors? If not, does it help if it is? }}
\end{itemize}
\noindent
In fact any document can be fed to the \latextohtml{} processor,
but it is designed specifically to recognise and sensibly translate
the intentions expressed by \LaTeX{} markup commands. Although sensible
results can be obtained even when the \LaTeX{} source is not valid,
the most reliable translations are obtained when it is. 
Relevant issues are discussed 
\hyperref{in a later section}{in Section~}{}{devel}.


\godown{quest6}\label{quest5}%
\begin{itemize}
\item \latexhtml
{\emph{When developing a document which contains special \texttt{HTML}
features, is it best to regularly test it in \LaTeX{} or with \latextohtml{}? }}
{{\large When developing a document which contains special \texttt{HTML}
features, is it best to regularly test it in \LaTeX{} or with \latextohtml{}? }}
\end{itemize}
\noindent
The answer to such a question changes as the developer gains
more experience with the available tools.
Some aspects to be considered are discussed 
\hyperref{in a later section}{in Section~}{}{devel} of this manual.


\medskip\htmlrule\goback{overview}\label{quest6}\medskip
\noindent
Information relevant to obtaining the latest version of \latextohtml, 
installation within the local environment, and where to look for
help when things do not go as expected, can be found in 
\hyperref{the support section}{Section~}{}{sec:sup}.

and formulas will be displayed in character-based browsers,
such as \env{lynx}.

\index{color!coloured text}%
\index{color!coloured background}%
\index{image!backdrop}\index{backdrop!tiled with an image}%
\item 
coloured text and/or background is fully supported, as is the
ability to use an image to create a tiled backdrop.

\index{extensions@extensions\label{IIIexts}!new commands}%
\index{extensions!new environments}%
\index{extensions!new theorems}\index{extensions!in style-files}%
\item

\index{footnotes}\index{table of contents}\index{list of figures}%
\index{list of tables}\index{bibliography}\index{index}%
\item 
handles footnotes\footnote{Like this!}, 
tables of contents, lists of figures and tables, 
bibliographies and can generate an index.
By including hyperlinks between index entries, 
simple navigation aids can be built into the index, for easy browsing.

\index{accents}%%
\item 
translates \LaTeX{}  accent and special character 
commands (e.g. \. {A} \O {\"o} \pounds \copyright \P) to
the equivalent ISO--Latin--1 or Unicode character set,
else an image can be created;

\index{hypertext links}\index{hypertext links!multi-media resources}%
\index{hypertext links!Internet services}%
\index{hypertext links!news/sound/video}%
\item 
recognises hypertext links (to multi-media resources or
arbitrary Internet services such as 
\textsl{sound}, \textsl{video}, \textsl{ftp}, \textsl{http}, \textsl{news}) and
links which invoke arbitrary program scripts---all expressed as \LaTeX{}  
commands;

\index{conditional text}%

the hypertext version, or only for the paper (\texttt{.dvi}) version;\par
%
\index{HTML@\texttt{HTML}!raw@raw \texttt{HTML} commands}%
\index{HTML@\texttt{HTML}!interactive forms}%
\item 
can include raw \texttt{HTML} in a \LaTeX{}  document 
(e.g. in order to specify interactive forms);

\index{LaTeX commands@\LaTeX{} commands}\label{hypcites}%
\index{Common LaTeX@Common \LaTeX{} Commands!latex blue@\LaTeX{} blue book}%
\index{LaTeX blue book@\LaTeX{} blue book}%

\strikeout{at least the \textit{Common }\LaTeX{} \textit{Commands}
summarised at the back of\\}%
virtually all of the concepts and commands described in
the \LaTeX{} \htmlcite{blue book}{lamp:latex}, 
where there is a meaningful interpretation appropriate to
an \texttt{HTML} document.
Also many other \LaTeX{} constructions are handled, including many described in the 
\LaTeX{} \hypercite{\textit{Companion}}{\textit{Companion}}{}{goossens:latex}
and \LaTeX{} \hypercite{\textit{Graphics Companion} (e.g. \Xy-pic)}%
{\textit{Graphics Companion}}{\Xy-pic}{goossens:latexGraphics};

\index{HTML@\texttt{HTML}!Version 2.1}%
\index{HTML@\texttt{HTML}!Version 3.0}%
\item 
can be configured to translate equations either
as GIF images or as \texttt{HTML} 3.0 mark-up
(as browsers become available which are suitable for the task),
or by making images of subparts of equations, as required.

\index{references!symbolic}\index{references!document segments}%
\index{document!illustrative examples}%
\item 
links symbolic references across document segments which have been
independently processed;%

\index{LaTeX commands@\LaTeX{} commands!embedded}%
\index{LaTeX commands@\LaTeX{} commands!not syntactically legal}%
\item 
will try to translate any document with embedded \LaTeX{} commands, 
irrespective of whether it is complete or syntactically legal.
