+% \section{Intoduction}
+%
+% This package enables the processing of HTML codes. The
+% \verb|\dohtml| command 
+%  allows fragments of HTML to be placed within a \LaTeX\
+% document,
+%\begin{verbatim}
+% \dohtml
+% <html>
+% html markup ...
+% </html>
+%\end{verbatim}
+% The \verb|<html>|\ldots\verb|</html>| is \emph{required}. (It is
+% anyway a good idea to have these tags in an HTML document.)
+%
+% The \verb|\htmlinput| command is similar, but takes a file
+% name as argument. In that case the file need not necessarily start
+% and end with \verb|<html>|\ldots\verb|</html>|.
+%
+% This package covers most of the HTML2 DTD, together with the
+% mathematics extensions from HTML3.\footnote
+% {The draft specification of HTML3 has expired, and the W3C group
+% are currently devising a new proposed extension of HTML, so the
+% mathematics typesetting part of this package may need substantial
+% revision once a final specification of the HTML mathematics markup
+% is agreed.}
+% The rest of HTML3 may be added at a later date.
+%
+% Its current incarnation has not been extensively tested, having been
+% thrown together during the last couple of weeks in response to a
+% question on \texttt{comp.text.tex} about the availability of such a
+% package.
+%
+% The package falls into three sections. Firstly the options section
+% allows a certain amount of customisation, and enabling of
+% extensions. Not all these options are fully operational at present.
+% Secondly comes a section that implements a kind of SGML parser. This
+% is not a real conforming SGML parser (not even a close approximation
+% to such a thing!) The assumption (sadly false in the anarchic WWW)
+% is that any document will have been validated by a conforming SGML
+% parser before it ever gets to the stage of being printed by this
+% package. Finally are a set of declarations that essentially map the
+% declarations of the HTML DTD into \LaTeX\ constructs.
+%
+% \section{Options}
+%
+% \subsection{HTML Level}
+% The options \texttt{html2} (the default) and \texttt{html3} control
+% HTML variant supported. Using the \texttt{html3} option will use up a
+% lot more memory to support the extra features, and the math entity
+% (symbol) names. Against my better judgement there is also a
+% \texttt{netscape} option to allow some of the non-HTML tags accepted
+% by that browser.
+%
+% \subsection{Headings}
+% The six options \texttt{chapter}, \texttt{chapter*}, \texttt{section},
+% \texttt{section*}, \texttt{subsection} and \texttt{subsection*}
+% Determine to which \LaTeX\ sectional command the HTML element
+% \texttt{h1} is mapped. (\texttt{h2}--\texttt{h6} will
+% automatically follow suit.) The default is \texttt{section*}.
+%
+% \subsection{Double Quote Handling}
+% Most HTML pages use |"| as as a quotation mark in text, for
+% example:
+%\begin{verbatim}
+% quoted "like this" example
+%\end{verbatim}
+%
+% This slot in the ISO latin-1 encoding is for `straight' double
+% quotes. Unfortunately the Standard \TeX\ fonts in the OT1 encoding
+% do not have such a character, only left and right quotes, ``like
+% this''. By default this package uses the \texttt{straightquotedbl}
+% option which uses the \LaTeX\ command |\textquotedbl| to render
+% |"|. If used with the T1 encoded fonts |\usepackage[T1]{fontenc}|
+% then the straight double quote from the current font is used. With
+% OT1 fonts, the double quote is taken from the |\ttfamily| font,
+% which looks \texttt{"}like this\texttt{"} which is fairly
+% horrible, but better than the alternative which is ''like this''.
+%
+% The \texttt{smartquotedbl} option redefines |"| so that it produces
+% alternatively an open double quote `` then a close ''. As there is a
+% chance of it becoming confused, it is reset to `` at the beginning
+% of every paragraph, whatever the current mode.
+%
+% Neither of these options affects the use of |"| as part of the SGML
+% syntax to surround attribute values.
+%
+% In principle the package ought to have similar options dealing with
+% the single quote, but there the situation is more complicated due to
+% its dual use as an apostrophe, so currently the package takes no
+% special precautions: all single quotes are treated as a closing
+% quote/apostrophe. Also the conventions of `open' and `close' quotes
+% only really apply to English. If someone wants to suggest what the
+% package should do with |"| in other languages\ldots
+%
+% \subsection{Images}
+% The default option is \texttt{imgalt} This means that all inline
+% images (the HTML \texttt{img} element) are replaced by the text
+% specified by the \texttt{alt} attribute, or \textsf{[image]} if no
+% such attribute is specified.
+%
+% The \texttt{imggif} option\footnote{one day} uses the
+% \verb|\includegraphics|  command so that inline images appear as
+% such in the printed version.
+%
+% The \texttt{imgps} option\footnotemark[1] is similar to
+% \texttt{imggif} but first replaces the extension \texttt{.gif} at
+% the end of the source file name by \texttt{.ps}. This will enable
+% drivers that can not include GIF files to be used, as long as the
+% user keeps the image in both PostScript and Gif formats.
+%
+% \subsection{Hyperref}
+%
+% Several options control how the HTML anchor tag is treated.
+%
+% The default \texttt{nohyperref} option ignores name anchors, and
+% typesets the body of src anchors using |\emph|.
+%
+% The \texttt{ftnhyperref} option is similar to \texttt{nohyperref},
+% but adds a footnote showing the destination address of each link,
+% as specified by the SRC attribute.
+%
+% If the \texttt{hyperref} option is specified, the hypertext markup
+% in the HTML file will be replicated using the
+% hypertext specials of the Hyper\TeX\ group. If in addition the
+% \textsf{hyperref} package is loaded, the extra features of that
+% package may be used, for instance producing `native PDF' specials
+% for direct use by Adobe distiller rather than producing the specials
+% of the hyper\TeX\ conventions.
+%
+% The \texttt{dviwindo} option converts the hypertext information in
+% the HTML into the |\special| conventions of Y\&Y's \emph{dviwindo}
+% previewer for Microsoft Windows.
+%
+% \subsection{Big Integrals}
+% \LaTeX\ does not treat integral signs as variable sized symbols,
+% in the way that it treats delimiters such as brackets. In common
+% with summation signs and a few other operators, they come in
+% just two fixed sizes, a small version for inline mathematics, and a
+% large version used in displays. In fact by default \LaTeX\ always
+% uses the same two sizes (from the 10\,pt math extension font) even if
+% the document class has been specified with a size option such as
+% \texttt{12pt}, or if a size command such as |\large| has been used.
+%
+% The standard \textsf{exscale} package loads the math extension font
+% at larger sizes if the current font size  is larger than 10\,pt.
+%
+% The HTML3 math description explicitly states that integral signs
+% should be treated like delimiters and stretch if applied to a large
+% math expression. By default this package ignores this advice and
+% treats integral signs in the standard way, however an option
+% \texttt{bigint} does cause integral signs to `stretch' (or at least
+% be taken from a suitably large font). The standard Computer Modern
+% fonts use a very `sloped' integral which means that they are
+% not really suitable for being stretched. Some other math fonts, for
+% instance Lucida, have more vertical integral signs, and one could
+% imagine in those cases making an integral sign with a `repeatable'
+% vertical middle section so that it could grow to an arbitrary size, in
+% the way that brackets grow.
+%
+% \section{Latin-1 characters}
+% The SGML character entities for the ISO-Latin1 characters such as
+% \texttt{\&eacute;}  are recognised by this style, although as usual,
+% some of them such as the Icelandic thorn character,
+% \texttt{\&thorn;}, \verb|\th|, produce an error if the old `OT1'
+% encoded fonts are being used. These characters will print correctly
+% if `T1' encoded fonts are used, for example by declaring
+% \verb|\usepackage[T1]{fontenc}|~.
+%
+% HTML also allows direct 8-bit input of characters according to the
+% ISO-latin1 encoding, to enable this you need to enable latin-1 input
+% for \LaTeX\ with a declaration such as
+% \verb|\usepackage[latin1]{inputenc}|~.
+%
+% \section{Mathematics}
+% The HTML3 MATH element is fairly well supported, including the  BOX
+% and CLASS attributes.  (Currently only CHEM value for class is
+% supported, and as far as I can see the BOX attribute is only in the
+% report, not in the dtd.) The super and subscripts are supported,
+% including the shortref maps, however only the default right
+% alignment is 
+% implemented so far. The convention described in the draft report
+% for using white space to distinguish superscript positioning is
+% fairly \emph{horrible}!
+%
+%
+% The documentation that I could find on HTML3 did not include a full
+% list of the entity names to be used for the symbols. This
+% package currently \emph{only} defines the following entities, which
+% should be enough for testing purposes at least.
+%
+% \begin{itemize}
+% \item
+% |gt| ($>$) |lt| ($<$) (Already in the HTML2 DTD)
+%
+% \item
+% Some Greek letters.
+%
+% |alpha| ($\alpha$)
+% |beta| ($\beta$)
+% |gamma| ($\gamma$)
+% |Gamma| ($\Gamma$)
+%
+% \item
+% Integral and Sum. $\int$ grows large if the \texttt{bigint} package
+% option is given.
+%
+% |int| ($\int$)
+% |sum| ($\sum$)
+%
+% \item
+% Braces (The delimiters ()[] also stretch as expected in the BOX
+% element)
+%
+% |lbrace| ($\lbrace$)
+% |rbrace| ($\rbrace$)
+%
+% \item
+% A random collection of mathematical symbols:
+%
+% |times| ($\times$)
+% |cup| ($\cup$)
+% |cap| ($\cap$)
+% |vee| ($\vee$)
+% |wedge| ($\wedge$)
+% |infty| ($\infty$)
+% |oplus| ($\oplus$)
+% |ominus| ($\ominus$)
+% |otimes| ($\otimes$)
+%
+% \item
+% A Minimal set of trig functions:
+%
+% |sin| ($\sin$)
+% |cos| ($\cos$)
+% |tan| ($\tan$)
+%
+% \item
+% Also in the special context as attributes to ABOVE and BELOW elements
+% the entities:
+%
+% |overbrace| ($\overbrace{\quad}$)
+% |underbrace| ($\underbrace{\quad}$) and any (\TeX) math accent name.
+%
+% \end{itemize}
+%
+% \section{SGML Minimisation features}
+% SGML (and hence HTML) support various minimisation features that aim
+% to make it  easier to enter the markp `by hand'. These features make
+% the kind of `casual' attempt at parsing SGML as implemented in this
+% package somewhat error prone.
+%
+% Two particular features are enabled in HTML. The so called SHORTTAG
+% feature means that the name of a tag may be omitted if it may be
+% inferred from the context. Typically in HTML this is used  in
+% examples like
+%\begin{verbatim}
+% <title>A Document Title</>
+%\end{verbatim}
+% The end tag is shortened to |</>| and the system infers that
+% TITLE is the element to be closed.
+%
+% The second form of minimisation enabled in HTML is the OMITTAG
+% feature. Here a tag may be omitted altogether in certain
+% circumstances.
+% A typical example is the HTML list, where each list item is started
+% with |<li>| but the closing |</li>| at the end of the item may be
+% omitted and inferred by the following |<li>| or |</ol>| tag.
+%
+% This package is reasonably robust with respect to omitted
+% tags. However it only makes a half hearted attempt at supporting the
+% SHORTTAG feature. The TITLE example above would work, but nested
+% elements, with multiple levels of minimised end tags will probably
+% break this package.
+%
+% It would be possible to build a \LaTeX\ system that had full
+% knowledge of the HTML (or any other) DTD and in particular the
+% `content model' of every element, this would produce a more robust
+% parsing system but would take longer than I was prepared to
+% spend this week\ldots\ In anycase if you need a fully conforming SGML
+% parser, it probably makes sense to use an existing one (excellent
+% free parsers are freely available) and then convert the output of
+% the parser to a form suitable for \LaTeX. In that way all such
+% concerns about SGML syntax features such as minimisation will have
+% been resolved by the time \LaTeX\ sees the document.

+% \subsection{Netscape Non-HTML tags}
+%
+% Netscape allows certain tags that do not correspond to HTML elements.
+% These are  \emph{Bad Thing}. Originally the documentation of this
+% package stated that such `extensions' would not be supported, however
+% as a request came from \ldots\ldots\footnote{Name withheld to
+% protect the guilty} who also supplied most of the code in this
+% section (and also the table section), I have added some support
+% which is enabled if the \texttt{netscape} option is used.

+%
+%    |\HTML@not| is defined above in the netscape option:
+%     Naughty Nonstandard Extension Warning for things like
+%    |<center>| and |<font>|. (I thought these were
+%    Netscape-specific but the technical notes at Spyglass's web site
+%    showed that I was wrong. [mjd,1996/03/20])
