% \begin{abstract}
%   The standard \FoilTeX\ system is based on a visual rather than
%   logical formatting. Thus automatic conversion of \FoilTeX\ 
%   documents to HTML format is difficult. In particular, the
%   well-known \latextohtml\ converter gives unsatisfactory results
%   when used on \FoilTeX\ documents.
% 
%   This package provides integration between \FoilTeX\ and
%   \latextohtml. It adds sectioning commands and elements of logical
%   formatting to \FoilTeX\ and provides support for \FoilTeX\ commands
%   in \latextohtml. It also supports automatic creation of
%   \latextohtml\ images with proper font sizes and shapes when
%   converting \FoilTeX\ documents.

%
% \section{Introduction}
%
% Many people like to put the contents of their talks and lectures on
% the World Wide Web using tools like Nikos Drakos'
% \latextohtml~\cite{LaTeX2HTML}. Unfortunately, when one tries to
% convert the documents prepared in \FoilTeX~\cite{FoilTeX}, several
% problems emerge:
% \begin{enumerate}
% \item \FoilTeX\ does not have proper sectioning commands. Instead it
% has command like |\foilhead| and |\rotatefoilhead|, that are not
% recognized by \latextohtml. 
% \item \FoilTeX\ has commands like |\MyLogo| and |\Restriction| that
% have no correspondence in the HTML format.
% \item The equations and pictures processed by \latextohtml\ are too
% large and (for pictures) use Sans Serif fonts. This produces ugly
% |gif| inserts in HTML files.
% \end{enumerate}
%
% This package solves these problems by two methods:
% \begin{enumerate}
% \item It provides a \Perl\ script to teach \latextohtml\ the basic
% constructions of \FoilTeX\ and put the correct headers in the \latextohtml\
% |images.tex| file.
% \item It provides a \LaTeX\ package that implements sectioning
% commands in \FoilTeX.
% \end{enumerate}
%
% 
% \section{Installation}
% Since \FH\ is an \emph{add-on} to \FoilTeX\ and \latextohtml, you need both
% these programs installed and working prior to installation of
% \FH. This package is intended for \LaTeXe\ \emph{only}; I don't have
% enough time to port and test it under \LaTeX2.09. It is tested under
% \FoilTeX2.1 and \latextohtml96--\latextohtml98.
%
% The \FH\ distribution consists of the following files:
% \begin{itemize}
% \item |readme.v12|---Read Me file
% \item |foilhtml.dtx|---the fully documented code
% \item |foilhtml.ins|---the \LaTeX\ program extracting
% the code from the |.dtx| file. 
% \end{itemize}
% To install the package:
% \begin{enumerate} 
% \item Run \LaTeX\ on |foilhtml.ins|. This will
% create the following files:
% \begin{itemize}
% \item |foils.perl|---\Perl{} script for \latextohtml98
% \item  |foilhtml.sty| and |foilhtml.cfg|---\LaTeX\ style file and the
%   configuration file for user-customization,
% \item |foilhtml.drv|---documentation driver.
% \item |foilhtml-96.perl| and |foils-97.perl|---obsolete versions of
% \Perl{} scripts required \emph{only} if you have an obsolete installation
% of \latextohtml.
% \end{itemize}
% \item Install the script |foils.perl| in the directory where your
% \latextohtml{}  scripts reside (usually it is
% |styles| subdirectory of the main \latextohtml{} directory,
% e.~g. |/usr/local/lib/latex2html/styles|). 
% \item Tune the configuration file |foilhtml.cfg| according to your
%   taste and put it together with the file |foilhtml.sty| to the
%   directory read by \LaTeX\footnote{If you use |kpathsea| (e.~g. if
%     you have te\TeX\ distribution), you will need to run |texhash| to
%     update your search database}. 
% \item Run \LaTeX\ on  |foilhtml.drv| to produce the
%   documentation\footnote{The documentation driver |foilhtml.drv|
%   reads the contents of the file |foilhtml.dtx|, so do not delete
%   the latter until you produced the documentation.}.
% \item (Optional) to produce the documentation \emph{and} the code run
%   \LaTeX\ through the file |foilhtml.dtx|
% \end{enumerate}
%
% \subsection{Obsolete versions}
% 
% If you have older versions of \latextohtml, your best options is to upgrade. 
% However, if you cannot do this by some reason, you can use the previous
% versions of the perl scripts. Just rename the files |foilhtml-96.perl| 
% \emph{or} |foils-97.perl| to |foilhtml.perl| or |foils.perl| correspondingly
% and install them in the |styles| subdirectory.
%
% \section{Basic Usage}
%
% The usage of \FH\ could be very simple. Just add to the preamble of your
% document |\usepackage{foilhtml}|, for example 
% \begin{verbatim}
% \documentclass[20pt,dvips]{foils}
% \usepackage{foilhtml,html}
% \end{verbatim}
% and your \FoilTeX\ documents will be correctly parsed by
% \latextohtml\footnote{Actually, if you use \latextohtml97-1 or later, you
% don't need even to load the package |foilhtml|: unlike the old
% versions of \latextohtml, this one parses both \cs{usepackage} and
% \cs{documentclass} commands. However, you will want to load this
% package if you need the new \FoilTeX{} commands described below.}.
% The \FoilTeX-specific commands
% \DescribeMacro{\foilhead}\DescribeMacro{\rotatefoilhead} |\foilhead| and
% |\rotatefoilhead| will be translated by \latextohtml\ as
% starred |\subsection*| commands (this behavior could be changed in your
% |.latex2html-init| file---see Section~\ref{sec:config}).
%
% However, this is not the full story. In addition, you will be able
% to use ``normal'' sectioning 
% commands like |\section| and |\chapter| and even
% |\tableofcontents|.  By default, commands |\part| and |\chapter|
% produce new foils containing only titles of the corresponding, and
% the command |\section| starts a new foil. The starred forms of these
% commands produce unnumbered sections that are not included in the table of
% contents. 
%
% In the ``vanilla'' \FoilTeX\ the commands |\foilhead| and
% |rotatefoilhead| have both logical (they are close to sectioning
% commands) and visual meanings. If you want to convert your documents
% to HTML, you need to adhere to logical formatting. Therefore, their
% usage is discouraged. Most important, you should \emph{not} use the
% commands |\foilhead{}| and |\rotatefoilhead{}| without arguments to
% produce blank pages: they will be treated by \latextohtml\ as
% |\subsection*{}| commands with blank subsection name. Instead, use
% |\clearpage| and the commands |\portraitfoils| and |\landscapefoils|,
% described below.
%
% While the sectioning commands take care of the logical formatting,
% it is impossible to get rid of visual formatting of foils
% altogether. \FH\ package provides some new commands for visual
% formatting. 
%
% \DescribeMacro{\portraitfoils}\DescribeMacro{\landscapefoils} 
% \DescribeMacro{\portraitfoils*}\DescribeMacro{\landscapefoils*} 
% The commands |\portraitfoils| and |\landscapefoils| start a new foil
% with the selected orientation. Their starred forms do not eject the
% page, and the selected orientation begins only from the next
% sectioning command at the level of |section| or greater. Note that the
% explicit commands |\foilhead| and |\rotatefoilhead| might change the
% orientation of the produced pages. However, the default orientation
% will be restored by the next sectioning command on the level of
% |section| or greater.
%
% \section{Customization}
% \label{sec:config}
% \FH\ should work ``right out of the box''. However, there some ways
% to customize its behavior for picky users.
%
% \subsection{Configuring the \latextohtml{} behavior}
% There are three \Perl\ variables that control translation that could
% be set in your 
% |.latex2html-init| file
%
% \DescribeMacro{$FOILHEADLEVEL}
% The value of |$FOILHEADLEVEL| describes the level of sectioning for
% explicit |foilhead| and |rotatefoilhead| commands. By default it is
% 4 (subsection). Other values are 1 (part), 2 (chapter), etc.\ up to 7
% (subparagraph).
%
% \DescribeMacro{$FOILCLASS}\DescribeMacro{$FOILOPTIONS}
% The header of the |images.tex| is
% \begin{verbatim}
% \documentclass[$FOILOPTIONS]{$FOILCLASS}
% \end{verbatim} 
% The defaults are |10pt| and |article|. The variables can be set to any
% valid \LaTeX\ values.
%
% For example, the following lines in your |.latex2html-init| file:
% \begin{verbatim}
% $FOILHEADLEVEL = 2;
% $FOILOPTIONS = '12pt';
% $FOILCLASS = 'book';
% \end{verbatim}
% produce HTML file with |foilhead| commands translated as
% Chapters, and the images created as for a 12pt book.
% 
% \subsection{\LaTeX\ variables and options}
% There are several ways to change the look of the \LaTeX\
% document. 
%
% \DescribeMacro{\contentsname}
% By default, the Table of Contents is titled ``Outline'' in the
% printed document. This could be changed by changing the macro
% |\contentsname| like this:
% \begin{verbatim}
% \renewcommand{\contentsname}{The Outline of Today's Talk}
% \end{verbatim}
% Note that the in the HTML version Table of Contents is still called
% ``Contents''. This could be changed separately in your
% |.latex2html-init| file. 
%
% \DescribeMacro{[pagesintoc]}\DescribeMacro{[nopagesintoc]}
% By default, the Table of Contents does not include the page numbers
% of the corresponding sections (they have little sense for a
% lecture). However, if you wish to include them in the Table of
% Contents, use package option |pagesintoc|. The package option
% |nopagesintoc| (default) suppresses the page numbers.
%
% By default, |foilhtml| does \emph{not} number even the non-starred
% sections, subsections, etc. This behavior is determined by the variable
% |secnumdepth| (by default 0). This variable has the same meaning
% here, as in the standard \LaTeX\ classes. All
% sectioning units of the level larger than |secnumdepth| are
% numbered, and the others are not. 
%
% \subsection{\LaTeX\ configuration file}
% If the file |foilhtml.cfg| exists, it is loaded by the style
% |foilhtml.sty|. If you use some customization code often, you can
% put it there. A sample configuration file is provided in the
% distribution; feel free to hack it.
%
% \section{New versions and bug reports}
%
% Feel free to send bug reports to |boris@plmsc.psu.edu|. You can find
% new versions of the package on my home page
% (|http://www.plmsc.psu.edu/|\~{}|boris| or on CTAN.

% \DescribeMacro{$FOILHEADLEVEL}
% Now we define |\foilhead| and |\rotatefoihead| as sectioning
% commands. By default their level is ``section'', but this can be used
% by setting |$FOILHEADLEVEL| to 1 (part), 2 (chapter), 3 (section),
% etc. up to 7 (subparagraph). Note that this will affect only \latextohtml\
% sectioning commands. The typesetting will the same: |<H1>|-level
% headings. Note, that article class does not have chapters,
% so if you want to make |$FOILHEADLEVEL| to be 2, you need to
% redefine |$FOILCLASS| below. Otherwise \TeX ing |images.tex| will
% give an error.
%
% \begin{macrocode}
 $FOILHEADLEVEL = 4 unless defined($FOILHEADLEVEL);
 %section_commands=('foilhead',$FOILHEADLEVEL,

% \section{\LaTeX\ style}
% \subsection{Initialization and processing options}
% First, let us ask (not so) nicely for \LaTeX\
%    \begin{macrocode}
%<*package>
\NeedsTeXFormat{LaTeX2e}
%    \end{macrocode}
%
% \begin{macro}{\@pagesintoc}
% Now let us check whether we need pages in toc:
%    \begin{macrocode}
\newif\if@pagesintoc
\DeclareOption{pagesintoc}{\@pagesintoctrue}
\DeclareOption{nopagesintoc}{\@pagesintocfalse}
\ExecuteOptions{nopagesintoc}
%    \end{macrocode}
% \end{macro}
% 
% \begin{macro}{\c@secnumdepth}
% We need to set |secnumdepth| before loading the configuration file:
%    \begin{macrocode}
\setcounter{secnumdepth}{0}
%    \end{macrocode}
% \end{macro}
% Now let us check the configuration file:
%    \begin{macrocode}
\InputIfFileExists{foilhtml.cfg}{%
  \typeout{Loading configuration file foilhtml.cfg}}{%
  \typeout{Configuration file foilhtml.cfg is not found. Using default
  options.}}
%    \end{macrocode}
%
% And now we construct a sample configuration file
%    \begin{macrocode}
%</package>
%<*cfg>
%%
%% The default options go here
%%
\ExecuteOptions{nopagesintoc}
%%
\AtEndOfPackage{\setcounter{secnumdepth}{0} % Customization goes here
}
%</cfg>
%<*package>
%    \end{macrocode}
%
% \DescribeMacro{\if@portraitfoils} 
% The flag |\if@portraitfoils| controls what kind of foils we produce
% for sectioning commands: portrait or rotated. We put it here because
% we want the global option |landscape| to work intelligently\ldots
%    \begin{macrocode}
\newif\if@portraitfoils
\@portraitfoilstrue
\DeclareOption{landscape}{\@portraitfoilsfalse}
%    \end{macrocode}
%
% Processing options:
%    \begin{macrocode}
\ProcessOptions
%    \end{macrocode}
% 
% \subsection{Checking the caller}
% Let us check where we are. The package could be loaded either from
% |foils| document class or from |article| (or other) documentclass
% (e.~g. from |images.tex|). We don't want to do anything in the
% latter case. So let us check whether some \FoilTeX\ command is
% defined: 
%    \begin{macrocode}
\@ifundefined{foilhead}{%
%    \end{macrocode}
% If we are \emph{not} called by \FoilTeX, we should disable
% \FoilTeX-specific commands. The \latextohtml{} script does not allow
% them in the document body, but, unfortunately, leaves them in the
% preamble. So we take care of them:

 }{%
%    \end{macrocode}
%
% \subsection{Rotating commands}
% \begin{macro}{\portraitfoils}
% \begin{macro}{\portraitfoils*}
% \begin{macro}{\landscapefoils}
% \begin{macro}{\landscapefoils*}
% The rotating commands set |\if@portraitfoils| and (for unstarred
% variants) eject the foil using |\foilhead|
%    \begin{macrocode}
 \newcommand{\portraitfoils}{%
   \@ifstar{\@portraitfoilstrue}{%
   \@portraitfoilstrue\foilhead[-\foilheadskip]{}}}

% \end{macro}\end{macro}\end{macro}\end{macro}
%
% \subsection{Sectioning commands}
%
% The stuff here is mostly stolen from
% |classes.dtx|~\cite{classes}---however, we implement the high level
% sectioning commands through |\foilhead|. 
%
% \begin{macro}{\chaptermark}
% First, mark commands (anybody uses marks for foils out here?) The
% file |latex.ltx| defines all of them but |\chaptermark|, so we
