The following sections document the actual implementation of the \pkg{lwarp} package.

The small numbers at the left end of a line refer to line numbers
\margintag{line numbers}
in the \texttt{lwarp.sty} file.

Blue-colored tags in the left margin
\margintag{subjects}
aid in quickly identifying the subject of each paragraph.

Black-colored tags in the left marign are used to
\margintag{objects}
identify programming objects such as files, packages,
environments, booleans, and counters.
Items without a tag are command macros.
Each of these also appears in the index as
\margintag{index entries}
individual entries, and are also listed together under ``files'', ``packages'', ``environments'',
``booleans'', and ``counters''.

Special warnings are marked with a warning icon.

code apply to the generation of \acro{HTML}, print, or both forms of output.
}

\newcommand{\limitstext}{\cs{textbf}, etc.\ are supported,
but \cs{bfseries}, etc.\ are not yet supported.}

\newcommand{\limitsverse}{%
\DescribeMacro{\attrib}
The documentation for the \pkg{verse} and \pkg{memoir} packages suggest
defining an \cs{attrib} command, which may already exist in current documents,
but it will only work for print output.
\pkg{lwarp} provides \cs{attribution}, which
works for both print and \acro{HTML} output.  To combine the two so that
\cs{attrib} is used for print and \cs{attribution} is used for \acro{HTML}:

\begin{docsidebar}
\ttfamily
\cs{begin}\{warpHTML\}

\cs{let}\cs{attrib}\cs{attribution}

\cs{end}\{warpHTML\}
\end{docsidebar}

\DescribeLength{vleftskip}
\DescribeLength{vleftmargini}
These lengths are used by \pkg{verse} and \pkg{memoir} to control the left margin,
and they may already be set by the user for print output.  New lengths
 \DescribeLength{HTMLvleftskip}\DescribeLength{HTMLleftmargini}
\cs{HTMLvleftskip} and \cs{HTMLleftmargini} are provided to control the
margins in \acro{HTML} output.  These new lengths may be set by the user
before any \env{verse} environment, and persist until they are manually changed again.
One reason to change \cs{HTMLleftmargini} is if there is a wide
\cs{flagverse} in use, such as the word ``Chorus'', in which case the value of
\cs{HTMLleftmargini} should be set to a wide enough length to contain ``Chorus''.
The default is wide enough for a stanza number.

Horizontal spacing relies on \texttt{pdftotext}'s ability to discern the
\texttt{-layout} of the
text in the \acro{HTML}-tagged \acro{PDF} output.  For some settings of
\cs{HTMLleftmargini} or \cs{HTMLleftskip} the horizontal alignment may not work out
exactly, in which case a label may be shifted by one space.
}


\newcommand{\limitslateximagefontsize}{%
The size of the math and text used
\margintag{SVG image font size}
in the \acro{SVG} image may be adjusted
\index{font>size --- lateximage}%
\index{font>size --- math, SVG}%
\index{math>font size --- SVG}%
\index{lateximages>font size}%
by setting \cs{LateximageFontSizeName} to a font size name --- \emph{without the backslash}, for ex: \\
\hspace*{.5in}\texttt{\cs{renewcommand}\{\cs{LateximageFontSizeName}\}\{\textcolor{red}{large}\}}
}


\newcommand{\limitsmath}{%
Math may be rendered as \acro{SVG} graphics or using the \textsc{MathJax} JavaScript display engine.
\index{JavaScript>MathJax}

For \acro{SVG} math,
\margintag{SVG math option}
math is rendered as usual by \LaTeX{} into the initial \acro{PDF} file using the
\index{math>SVG summary}%
\index{SVG>math summary}%
current font\footnote{See \cref{sec:xfrac} regarding fonts and fractions.},
then is captured from the \acro{PDF} and converted to \acro{SVG} graphics
via a number of utility programs.
The \acro{SVG} format is a scalable-vector web format, so math may be typeset by \LaTeX{}
with its fine control and precision, then displayed or printed at any size,
depending on (sometimes broken) browser support.
An \acro{HTML} \texttt{ALT} tag carries the \LaTeX{} code which generated the
math, allowing copy/paste of the \LaTeX{} math expression into other documents.

\limitslateximagefontsize

As currently implemented,
\margintag{SVG files}
each instance of math creates a new \acro{SVG} file.  In text with
many references to math variables, this can result in a large number of files with
duplicate content.  In the future, some method of content-based naming and checksumming
may be used to remove the need for duplicate files.

Another approach would be
\margintag{SVG inline}
to in-line the \acro{SVG} files directly into the \acro{HTML}.
This avoids having a large number of files and potentially speeds loading the images,
but dis-allows the possibility of sharing one file among many instances without
user intervention.

Others have used \acro{PNG} files,
\margintag{PNG files}
sometimes pre-scaled for print resolution but displayed
on-screen at a scaled down size.  This allows high-quality print output at the expense
of larger files, but \acro{SVG} files are also larger as well.

Conversion to Math\acro{ML} might be a better approach,
\margintag{MathML}
among other things
allowing a more compact representation of math than \acro{SVG} drawings.
Problems with Math\acro{ML} include limited browser support and some
issues with the fine control of the appearance of the result.

The popular MathJax alternative (\url{mathjax.org}) may be used to display math.
\margintag{MathJax math option}
\DescribeProgram{MathJax}
\index{math>MathJax summary}
\index{MathJax>summary}

When MathJax is enabled, math is rendered twice:
\begin{enumerate}
\item As regular \LaTeX\ \acro{PDF} output placed inside an \acro{HTML} comment, allowing
equation numbering and cross referencing to be almost entirely under the control of \LaTeX, and
\item As detokenized printed \LaTeX{} commands placed directly into the \acro{HTML} output
for interpretation by the MathJax display scripts.  An additional script is used to
pre-set the equation number format and value according to the current \LaTeX\ values,
and the MathJax cross-referencing system is ignored in favor of the \LaTeX\ internal system,
seamlessly integrating with the rest of the \LaTeX\ code.
\end{enumerate}

Limitations when using MathJax include:
\margintag{MathJax limitations}
\DescribeProgram{MathJax}
\begin{itemize}
\item In document classes which have chapters,
	\margintag{chapter numbers}%
	\index{MathJax>tagged equations}%
	\index{tagged equations>Mathjax}%
	\cs{tag}ged equations have the chapter number prepended in \acro{HTML} output, unlike \LaTeX.
	\cs{tag*} equations (correctly) do not.
	This may be improved with future versions of the MathJax support script.

	\href{https://groups.google.com/forum/\#!topic/mathjax-users/jUtewUcE2bY}
		{\texttt{https://groups.google.com/forum/\#!topic/\\
			\hspace*{2em}mathjax-users/jUtewUcE2bY}}

\item MathJax itself does not support subequations.
	\margintag{subequations}
\index{MathJax>subequations}%
\index{subequations>MathJax}%
	This may be improved by parsing the \LaTeX{}
	math expression to manually insert tags, but this has not yet been done.
\item Footnotes inside equations are not yet supported while using MathJax.
	\margintag{footnotes in math}
\item Math appearing inside a lateximage,
	\margintag{lateximage}
	and therefore also inside a \tikz{} or \env{picture}
	environment, is rendered as SVG math even if MathJax is used in the rest of the document.
\item Usage of \pkg{siunitx} inside a math equation
	\margintag{siunitx}
	is supported via a third-party MathJax extension.
	While inside a math expression, do not use \cs{SI} or \cs{si} inside \cs{text},
	where it will be rendered as normal text.
	\watchout[siunitx inside an equation]

		{\texttt{https://github.com/mathjax/MathJax-third-party-extensions/\\
		\hspace*{2em}tree/master/siunitx}}

\item MathJax does not automatically support custom \LaTeX{} macros,
	\margintag{\LaTeX{} macros}
	but they may be set up by the user.
\end{itemize}
}

\newcommand{\limitsgraphics}{%
\cs{graphicspath} only works for a single directory;
\margintag{\cs{graphicspath}}
all graphics must be in this directory.

For \cs{includegraphics}, avoid \texttt{px} and \% units for width and height, or
\margintag{units}
enclose them inside \env{warpHTML} environments.
For font-proportional image sizes, use \texttt{ex} or \texttt{em}.
For fixed-sized images, use
\texttt{cm}, \texttt{mm}, \texttt{in}, \texttt{pt}, or \texttt{pc}.
Using the keys \cmds{width=.5\lmacro{linewidth}},
or similar for \cmds{\lmacro{textwidth}} or \cmds{\lmacro{textheight}}
to give fixed-sized images proportional to a 6 by 9 inch text area.

\cs{includegraphics} accepts \texttt{width} and \texttt{height},
\margintag{options}
\texttt{origin}, \texttt{rotate} and \texttt{scale},
plus a new \texttt{class} key.

With \acro{HTML} output, \cs{includegraphics} accepts an optional
\margintag{\acro{HTML} class}
\texttt{class=xyz} keyval combination, and if this is given then
the \acro{HTML} output will include that class for the image.
The class is ignored for print output.

For \cs{includegraphics} the user should provide both \texttt{.pdf} and \texttt{.svg}
images, but always refer to
\watchout[image file types]
\texttt{.pdf} images in the document source.
All \cs{includegraphics} references to \texttt{.pdf} will automatically
be changed to \texttt{.svg} for \acro{HTML} output, and will be left as \texttt{.pdf} for print output.
Images may also be \texttt{.jpg} and \texttt{.png}, and will be used as-is for either output.

\cs{rotatebox} accepts the optional \texttt{origin} key.
\margintag{\cs{rotatebox}}

\cs{rotatebox}, \cs{scalebox}, and \cs{reflectbox} depend on modern browser
support.
\watchout[browser support]
The \cssthree{} standard declares that when an object is transformed
the whitespace which they occupied is preserved,
unlike \LaTeX{}, so expect some
ugly results for scaling and rotating.

	Keep the \cs{endfirsthead} row unchanged, as it is still relevent to \acro{HTML} output.

\item For S columns (from the \pkg{siunitx} package),
	\watchout[S columns]
	while producing print output,
	anything non-numeric must be placed
	inside \{ \} braces, including commands such as \cs{multirow}.
	While producing \acro{HTML} output, though, anything placed inside

	To resolve this problem, make a copy of the row, with one version
	for print output, containing the extra braces, and another version
	for \acro{HTML} output, without the extra braces, such as: \\
	\hspace*{.375in} \cs{warpprintonly}\{\texttt{1 \& 2 \& \textcolor{red}{\{}\cs{multirow}\{2\}\{2cm\}\{Text\}\textcolor{red}{\}} \& 3 \textbackslash\textbackslash\}} \\

\margintag{placement}

A line of text with an inline minipage
\watchout[inline]

because a paragraph is a block element and cannot be made \texttt{inline-block}.

There is limited support for minipages inside an \acro{HTML} \tag{span}.
\margintag{in a span}
An \acro{HTML} \tag{div} cannot appear inside a \tag{span}.
While in a \tag{span}, minipages and parboxes are ignored.

When using \cs{linewidth}, \cs{textwidth}, and \cs{textheight},

widths and heights are scaled proportionally to a 6\texttimes{}9 inch text area.

A new macro \cs{minipagefullwidth} requests
\margintag{full-width minipages}
that the next minipage be generated
without an \acro{HTML} \texttt{width} tag, allowing it to be the full width of
the display rather than the fixed width given.

Nested minipages adopt their parent's text alignment in \acro{HTML},

% \noindent
% The \pkg{lwarp} package allows \LaTeX\ to directly produce \htmlfive\ output,
% using external utility programs only for the final conversion of text and images.
% Math may be represented by \acro{SVG} files or MathJax.
%
% Documents may be produced by \LaTeX, \LuaLaTeX, or \XeLaTeX.
% A |texlua| script removes the need for system utilities such as |make| and |gawk|,
% and also supports |xindy| and |latexmk|.  Configuration is automatic at the
% first manual compile.
%
% Print and \acro{HTML} versions of each document may coexist, each with its own
% set of auxiliary files.  Support files are self-generated on request.
%
% A modular package-loading system uses the \pkg{lwarp} version of a package for
% \acro{HTML} when available.
% Several dozen \LaTeX\ packages are supported with these high-level source
% compatibility replacements.
%
% A tutorial is provided to quickly introduce the user to the major components
% of the package.

%
% \begin{description}
% \item[v0.21:] \
%	\begin{itemize}
%	\item Documentation for installing on Windows has been updated and improved.
%	\item For Windows compatibility, the |lateximages| shell script
%		has been replaced with a |lateximages.txt| file, which is parsed
%		by |lwarpmk| to generate lateximages.
%		This does not require any changes in the user's code.
%	\item Windows |lwarpmk again| now functions.
%	\item For improved error handling, \pkg{lwarp} now verifies the
%		order in which packages are loaded, and signals an error for misplaced packages.
%		\pkg{inputenc}, \pkg{fontenc}, \pkg{newunicode}, and \pkg{fontspec}
%		must be loaded before \pkg{lwarp}, and the other packages which
%		\pkg{lwarp} knows about must be loaded after.
%	\item \pkg{lwarp} no longer requires a \cs{title} be assigned.
%	\end{itemize}
% \item[v0.20:] \
%	\begin{itemize}
%	\item The |makefile| and related infrastructure
%		has been replaced by the |lwarpmk| utility.
%		This provides increased portability, reduced dependencies,
%		and much simpler installation and setup.
%	\item The |lwarp-newproject| package is now used to locally create
%		support files.
%	\item The print and \acro{HTML} versions of a document may co-exist with their
%		own sets of auxiliary files.
%	\item Package handling is now controlled by a modular system which
%		looks for and loads an |lwarp-<package>| version if available.
%	\item High-level source compatibility is provided for all supported
%		packages, almost totally eliminating the need
%		for |warpprint| and |warpHTML| environments.
%	\item A large number of additional packages are supported.
%	\item A new tutorial is included in the documentation, and
%		many obsolete sections have been removed.
%	\item \cs{NewHTMLdescription} sets the \acro{HTML} meta description tag for each file.
%		See \cref{sec:htmldescription}.
%	\item \cs{HTMLFileName} may now be empty, allowing filenames without a prefix.
%		Lwarp no longer automatically appends a |-| character.
%		\watchout
%		For existing projects, add a |-| to the end of \cs{HTMLFileName}.
%	\item \cs{HomeHTMLFileName} and \cs{HTMLFileName} no longer use
%		escaped underscore\watchout\
%		characters.  Underscores may be used in filenames as-is.
%	\item \pkg{lwarp} now tries to auto-detect the operating system,
%		and \cs{warpOSwindows} is only needed if the auto-detection
%		fails to detect Windows.
%	\item Tabular column types |@|, |>|, and |<| are now supported.
%	\item |BlockClass| and \cs{InlineClass} add an optional style.
%	\item The |sidebar| and |example| environments have been moved to the
%		test suite, and are no longer included in \pkg{lwarp}.
%	\end{itemize}
% \item[v0.19:] \
%	\begin{itemize}
%	\item \textsc{MathJax} now may be used to display math via the |mathjax| option.
%		See \cref{sec:loading,sec:limitsmath}.
%	To use MathJax with a pre-existing project,
%	\watchout
%	copy or link the file |lwarp_mathjax.txt| to the project's directory.
%	\item \cs{rule} added, supporting width, height, raise, \cs{textcolor}.
%	\item \cs{LateximageFontSizeName} provides user-adjustable font size for math
%		and \env{lateximage}s.
%	\item \cs{minipagefullwidth} requests that the next minipage be
%		full-width in \acro{HTML}, but still the assigned width in print.
%	\item \env{minipage} improved side-by-side rendering.
%	\item CSS class |tablenotes| is provided for table note items.
%	\item \cs{warpprintonly} replaces \cs{rowprintedonly},
%		and \cs{warpHTMLonly} is added.  These behave like the \env{warpprint}
%		\watchout
%		and \env{warpHTML} environments, and are generally useful, so they replace
%		the previously table-specific syntax.
%	\item \pkg{cleveref} is loaded \cs{AtEndPreamble} for improved reliability.
%		See \cref{sec:cleveref}.
%	\item \cs{xfracHTMLfontsize} controls \pkg{xfrac} font size in \acro{HTML}.
%	\item \tikz\ improved catcode handling.
%	\end{itemize}
% \item[v0.18:] \
%	\begin{itemize}
%	\item The \pkg{verse} package and the verse-related commands from
%		the \pkg{memoir} package are now supported.
%	\item Responsive web design has been improved for the sideTOC.
%	\item \cs{includegraphics} now maintains relative sized for em, ex, and \%.
%	\end{itemize}
% \item[v0.17:] \
%	\begin{itemize}
%	\item \pkg{mdframed} package is supported.
%	\end{itemize}
% \item[v0.16:] \
%	\begin{itemize}
%	\item Font and input encoding are now controlled by the user, and
%		\pkg{lwarp} is loaded after fonts have been selected.
%	\item Support for \XeLaTeX{} and \LuaLaTeX.  See \cref{sec:fonts}.
%	\end{itemize}

% \section{Introduction}
% \changes{v0.19}{2016/05/25}{Introduction: MathJax support mentioned.}
%
% The \pkg{lwarp} project aims to allow a rich \LaTeX{} document to be converted to a reasonable \acro{HTML}
% interpretation.  No attempt has been made to force \LaTeX{} to provide for every
% \acro{HTML}-related possibility, and \acro{HTML} cannot exactly render every possible \LaTeX{} concept.
% Where compromise is necessary, it is desirable to allow the print output to remain
% typographically rich, and compromise only in the \acro{HTML} conversion.
%
% Several ``modern'' features of \htmlfive, \cssthree, and \acro{SVG}
% are employed to allow a fairly feature-rich document
% without relying on the use of Javascript.
% Limited testing on older browsers show that these new features
% degrade gracefully, although the \acro{SVG} format
% for math may not be available on small cell phones.
%
% |pdflatex|, |xelatex|, or |lualatex| is used, allowing \pkg{lwarp} to process the usual image formats.
% While generating \acro{HTML} output, \acro{SVG} files are used in placed of \acro{PDF}.
% Other formats such as \acro{JPG} are used as-is.
%
% \acro{SVG} images may be used for math,
% and are also used for \env{picture}, and \tikz{} environments,
% as this format has
% better browser and e-book support than Math\acro{ML} (as of this writing),
% while still allowing for the high-quality display and printing of images (again, subject to potentially
% bug-ridden\footnote{Firefox has had an on-again/off-again bug for quite some time regareding
% printing \acro{SVG}s at high resolution.} browser
% support).\footnote{Aside --- The author, being a programmer, believes in the movement towards
% ``logical punctuation''.  (Look it up.)
%
% Aside to the aside --- The author also believes that space should be on
% either side of an em-dash, employing the symbol as a separator rather than something looking
% like a chemical \textbf{bond---as} shown here, but is willing to abide by
% Chicago style when necessary.}
% Further, \acro{SVG} images allow math to be presented with
% the same precise formatting as in the print version.
% Math is accompanied by ALT tags holding the \LaTeX{} source for the expression, allowing it to be
% copy/pasted into other documents.\footnote{There seems to be some debate as to whether
% Math\acro{ML} is actually an improvement over \LaTeX{} for sharing math.  The author has no
% particular opinion on the matter, except to say that in this case \LaTeX{} is much easier to implement!}
% Custom \LaTeX{} macros may be used as-is in math expressions, since the math is evaluated
% entirely inside \LaTeX.
%
% The \textsc{MathJax} JavaScript display engine may be selected
% for math display instead of using \acro{SVG} images.
% Subject to browser support and Internet access,
% MathJax allows an \acro{HTML} page to display
% math without relying on a large number of external image files,
% one per math expression.  \pkg{lwarp} maintains \LaTeX\ control for cross-referencing
% and equation numbering\,/\,formatting.
%
% \hfill\rule[.7ex]{.3\linewidth}{.4pt}\hspace*{\fill}
%
% The \pkg{lwarp} package allows \LaTeX{} to directly generate \htmlfive{} tags from a \LaTeX{}
% source document, with only minor intervention on the user's part.
% A |texlua| program called |lwarpmk| is used to process either the print or \acro{HTML}
% version of the document.  A few external utility programs are used to finish
% the conversion from a \LaTeX{}-generated \acro{PDF} file which happens to have \htmlfive{} tags,
% to a number of \htmlfive{} plain-text files and accompanying images.
%
% A special |lwarp-newproject| package is used to set up the auxiliary files necessary for
% the \acro{HTML} conversion.  Included is a parallel version of the user's source document,
% |<sourcename>-html.tex|, which selects \acro{HTML} output and then inputs the user's own source.
% This process allows both the printed and \acro{HTML} versions to co-exist side-by-side,
% each with their own auxiliary files.
%
% When requesting packages during \acro{HTML} conversion,
% |lwarp| first looks to see if it has its own modified version
% to use instead of the usual \LaTeX\ version.  These |lwarp-packagename.sty| files contain
% code used to emulate or replace functions for \acro{HTML} output.
%
% Enough functionality is provided to convert a typical article containing technical content.
% Not every package has been tested, but many of the most useful ones are known to work,
% either as-is or through emulation with replacement code.  (See \cref{tab:supported} on
% page \pageref{tab:supported}.)
%
%
% \subsection{Supported packages and features}
% \changes{v0.15}{2016/04/05}{Docs: Moved the supported functions table to the introduction.}
% 
% \Cref{tab:supported} lists the various \LaTeX{} packages and macros which may be used.
% \emph{Supported} means that the package or macro may be used as-is,
% perhaps with minor limitations.
% \emph{Emulated} means that the original package or macro is not used, but similar
% functionality is provided in a way which is intended to be compatible with the
% user's \LaTeX{} code.
% \emph{Ignored} means that the package is not used, but nullified user-level macros
% and related counters, lengths, etc.\ are provided for source-level compatibility.
%
% Any package listed in \cref{tab:supported} probably works with little or no change to the
% user's source code.
% Special environments are provided to mark blocks of code which are for
% print only, \acro{HTML} only, or both, should it be necessary.

% \section{Alternatives}
% 
% Summarized below are several other ways to convert a \LaTeX{} or other document to \acro{HTML}.
% Where an existing \LaTeX{} document is to be converted to \acro{HTML}, \pkg{lwarp} may be
% a good choice.  For new projects with a large number of documents, it may be worth
% investigating the alternatives before decided which path to take.
%
% \subsection{Internet class}
%
% \changes{v0.21}{2017/02/15}{Docs: Added \protect\texttt{internet} class.}
%
% The closest to \pkg{lwarp} in design principle is the
% \DescribeClass{internet}
% \verb+internet+ class by Andrew Stacey
% (\url{https://github.com/loopspace/latex-to-internet}),
% an interesting project which directly produces several versions
% of markdown, and also \acro{HTML}\ and \acro{EPUB}.
% 
% 
%
% \subsection{TeX4ht}
%
% \url{http://tug.org/tex4ht/}\DescribeProgram{TeX4ht}
%
% This system uses native \LaTeX{} processing to produce a DVI file containing special commands,
% and then uses additional post-processing for the \acro{HTML} conversion by way of numerous configuration
% files.
% In some cases, \pkg{lwarp} provides a better \acro{HTML} conversion, and it
% supports a different set of packages.
% TeX4ht produces several other forms of output beyond \acro{HTML}.
%
% \subsection{Translators}
%
% \changes{v0.21}{2017/02/14}{Docs: Added TeX2page, GladTeX.}
%
% These systems use external programs to translate a subset of \LaTeX{} syntax into \acro{HTML}.
% Search for each on CTAN (\url{http:\\ctan.org}).

% \item [Glad\TeX:] \url{http://humenda.github.io/GladTeX/} \DescribeProgram{GladTeX}
% \end{description}
% 
% \subsection{AsciiDoc}
%
% AsciiDoc is one of the most capable markup languages, providing enough features to produce
% the typical technical-writing document with cross-references,
% and it writes \LaTeX{} and \acro{HTML}.
% \begin{description}

% \end{description}
%
% \subsection{Pandoc}
% \DescribeProgram{Pandoc}
%
% A markup system which also reads and writes \LaTeX{} and \acro{HTML}.
% \begin{description}
% \item [Pandoc:] \url{http://pandoc.org/}
% \end{description}
%
% (Watch for improvements in cross-references to figures and tables.)
%
% \subsection{Word Processors}
%
% It should be noted that the popular word processors
% \DescribeProgram{Word}\DescribeProgram{LibreOffice}\DescribeProgram{OpenOffice}
% have advanced through the years in their abilities
% to represent math with a \LaTeX-ish input syntax, unicode math fonts,
% and high-quality output, and also generate HTML with varying success.
% See recent developments in Microsoft\,\textregistered{} Word\,\textregistered{}
% and LibreOffice\,\texttrademark{} Writer.
%
% \subsection{Commercial Systems}
%
% Likewise, several professional systems exist whose
% \DescribeProgram{Adobe} \DescribeProgram{FrameMaker}
% \DescribeProgram{InDesign} \DescribeProgram{Flare} \DescribeProgram{Madcap}
% abilities have been advancing in the areas of typesetting, cross-referencing, and HTML generation.
% See Adobe\,\textregistered{} FrameMaker\,\textregistered{},
% Adobe\,\textregistered{} InDesign\,\textregistered{},
% and Madcap Flare\,\texttrademark{}.
%
% \subsection{Comparisons}
% \index{markup languages}
%
% AsciiDoc, Pandoc, and various other markup languages typically have a syntax which tries to be
% natural and human-readable, but the use of advanced features tends to require
% many combinations of special characters, resulting in a complicated mess of syntax.
% By contrast, \LaTeX{} spells things out in readable words but takes longer to type, although
% integrated editors exist which can provide faster entry and a graphic user interface.
% For those functions which are covered by the typical markup language
% it is arguable that \LaTeX{} is comparably easy to learn, while \LaTeX{} provides many more advanced
% features where needed, along with a large number of pre-existing packages which provide solutions
% to numerous common tasks.
%
% Text-based document-markup systems share some of the advantages of \LaTeX{} vs.\ a typical word
% processor.  Documents formats are stable.  The documents themselves are portable,
% work well with revision control,
% do not crash or become corrupted, and are easily generated under program control.
% Formatting commands are visible,
% cross-referencing is automatic, and editing is responsive.
% Search/replace with regular expressions provides a powerful tool for
% the manipulation of both document contents and structure.
% Markup systems and some commercial systems allow printed output
% through a \LaTeX{} back end, yielding high-quality results especially when the \LaTeX{}
% template is adjusted, but they lose the ability to use \LaTeX{} macros and
% other \LaTeX{} source-document features.
% 
% The effort required to customize the output of each markup system varies.
% For print output, \LaTeX{} configuration
% files are usually used.  For HTML output, a \acro{CSS} file will be available, but additional
% configuration may require editing some form of control file with a different syntax, such as XML.
% In the case of \pkg{lwarp}, CSS is used, and much HTML output is adjusted
% through the usual \LaTeX{} optional macro parameters,
% but further customization may require patching \LaTeX{} code.
% 
% The popular word processors and professional document systems each has a large
% base of after-market support including pre-designed styles and templates, and often include
% content-management systems for topic reuse.

%
% \subsection{Installing the \protect\pkg{lwarp} package}
%
% There are several ways to install \pkg{lwarp}.  These are listed here
% with the preferred methods listed first:
%
% \begin{description}
% \raggedright
%
% \item [Pre-installed:] Try entering into a command line:
%	\userentry{kpsewhich lwarp.sty}
%
% If a path to |lwarp.sty| is shown, then \pkg{lwarp} is already installed.
%
% \item [\TeX\ Live:]If using a \TeX\ Live distribution,
%	try installing via |tlmgr|:
%	\userentry{tlmgr install lwarp}
%
% \item [MiK\TeX:] If using MiK\TeX, try using the package installer.
%
% \item [Operating-system package:] The operating-system package manager may
%	already have |lwarp|, perhaps as part of a set of \TeX-related packages.
%
% \item [CTAN TDS archive:] \pkg{lwarp} may be downloaded from the Comprehensive \TeX\ Archive:
%	\begin{enumerate}
%	\item See \url{http://ctan.org/pkg/lwarp} for the \pkg{lwarp} package.
%	\item Download the TDS archive: |lwarp.tds.zip|
%	\item Find the \TeX\ |local| directory:
%		\begin{description}
%		\item[\TeX\ Live:] \
%
%			\userentry{kpsewhich -var-value TEXMFLOCAL}
%		\item[MiKTeX:] \
%
%			In the ``Settings'' window, ``Roots'' tab, look for a local TDS root.
%		\end{description}
%		This should be something like: \\
%		\hspace*{2em}|/usr/local/texlive/texmf-local/|
%	\item Unpack the archive in the TDS local directory.
%	\item Renew the cache:
%		\userentry{mktexlsr} \quad —\,or\,—
%		\userentry{texhash}
%
%		Or, for Windows MiK\TeX, start the program called |MiKTeX Settings (Admin)|
%		and click on the button called \textsf{Refresh FNDB}.
%	\end{enumerate}
%
% \item[CTAN \texttt{.dtx} and \texttt{.ins} files:] Another form of \TeX\ package
%	is the |.dtx| and |.ins| source files.  These files are used to create
%	the documentation and |.sty| files.
%
%	\begin{enumerate}
%	\item See \url{http://ctan.org/pkg/lwarp} for the \pkg{lwarp} package.
%	\item Download the zip archive |lwarp.zip| into your own |lwarp| directory.
%	\item Unpack |lwarp.zip|.
%	\item Locate the contents |lwarp.dtx| and |lwarp.ins|
%	\item Create the documentation: \userentry{pdflatex lwarp.dtx} (several times)
%	\item Create the |.sty| files: \userentry{pdflatex lwarp.ins}
%	\item Copy the |.sty| files somewhere such as the \TeX\ Live local tree
%		found in the previous CTAN TDS section, under the subdirectory: \\
%		\hspace*{2em}|<texlocal>/tex/latex/local/lwarp|
%	\item Copy the documentation |lwarp.pdf| to a |source| directory in the local tree,
%		such as: \\
%		\hspace*{2em}|<texlocal>/doc/local/lwarp|
%	\item Renew the cache:
%		\userentry{mktexlsr} \quad —\,or\,—
%		\userentry{texhash}
%
%		Or, for Windows MiK\TeX, start the program called |MiKTeX Settings (Admin)|
%		and click on the button called \textsf{Refresh FNDB}.
%
%	\item See \cref{sec:locallwarpmk} to generate your local copy of |lwarpmk|.
%	\item Once the local version of |lwarpmk.lua| is installed, it may be made
%		available system-wide as per \cref{sec:installlwarpmk}.
%	\end{enumerate}
% \item[Project-local CTAN \texttt{.dtx} and \texttt{.ins} files:] The
%		|.dtx| and |.ins| files may be downloaded to a project
%		directory, then compiled right there, alongside the
%		document source files.  The resultant |*.sty| and |lwarpmk.lua| files
%		may be used as-is, so long as they are in the same directory
%		as the document source.  This approach is especially useful if
%		you would like to temporarily test\margintag{Just testing!}\
%		\pkg{lwarp} before deciding whether to permanently install it.
% \end{description}
%
% \subsection{Installing the \protect\texttt{lwarpmk} utility}
% \label{sec:installlwarpmk}
%
% \changes{v0.21}{2017/02/22}{Docs: Installing on Windows.}
%
% {\small
% (Note: If |lwarpmk| is not already installed,
% it is easiest to use a local copy instead of installing it system-wide.
% See \cref{sec:locallwarpmk}.)
% }
%
% After the \pkg{lwarp} package is installed,
% you may need to setup the |lwarpmk| utility:
% \begin{enumerate}
% \item At a command line, try executing |lwarpmk|.  If the |lwarpmk| help message
%	appears, then |lwarpmk| is already set up.
%	If not, it is easiest to generate and use a local copy.
%	See \cref{sec:locallwarpmk}.
%
%	Otherwise, continue with the following:
%
% \item Locate the file |lwarpmk.lua|, which should be in the |scripts| directory
%	of the TDS tree.  On a \TeX\ Live or MiK\TeX\ system you may use
%	\userentry{kpsewhich lwarpmk.lua}
%
%	(If the file is not found, you may also generate a local copy and use it instead.
%	See \cref{sec:locallwarpmk}.)
%
% \item Create |lwarpmk|:
%	\begin{description}
%	\item [Unix:] Create a symbolic link and make it executable:
%		\begin{enumerate}
%		\item Locate the \TeX\ Live binaries:
%			\userentry{kpsewhich -var-value TEXMFROOT} \\
%			This will be something like: \\
%			\hspace*{2em}|/usr/local/texlive/<year>| \\
%			The binaries are then located in the |bin/<arch>| directory
%			under the root: \\
%			\hspace*{2em}|/usr/local/texlive/<year>/bin/<architecture>/| \\
%			In this directory you will find programs
%			such as |pdflatex| and |makeindex|.
%		\item In the binaries directory,
%			create a new symbolic link from the binaries directory to |lwarpmk.lua|:
%			\userentry{ln -s <pathtolwarpmk.lua> lwarpmk}
%		\item Make the link executable:
%			\userentry{chmod 0755 lwarpmk}
%		\end{enumerate}
%	\item [Windows \TeX\ Live:] Create a new |lwarpmk.exe| file:
%		\begin{enumerate}
%		\item Locate the \TeX\ Live binaries as shown above for Unix.
%		\item In the binaries directory, make a \emph{copy} of |runscript.exe|
%			and call it |lwarpmk.exe|
%			This will call the copy of |lwarpmk.lua|
%			which is in the |scripts| directory of the distribution.
%		\end{enumerate}
%	\item [Windows MiK\TeX:] Create a new |lwarpmk.bat| file:
%		\begin{enumerate}
%		\item Locate the binaries.  These will be in a directory such as: \\
%			\hspace*{2em}|C:\Program Files\MiKTeX 2.9\miktex\bin\x64| \\
%			In this directory you will find programs
%			such as |pdflatex.exe| and |makeindex.exe|.
%		\item Create a new file named |lwarpmk.bat| containing: \\
%			\hspace*{1em}
%			|texlua "C:\Program Files\MiKTeX 2.9\scripts\lwarp\lwarp.texlua" %*| \\
%			This will call the copy of |lwarpmk.lua|
%			which is in the |scripts| directory of the distribution.
%		\end{enumerate}
%	\end{description}
% \end{enumerate}
%
% \subsubsection{Using a local copy of \protect\pkg{lwarpmk}}
% \label{sec:locallwarpmk}
% It is also possible to use a local version of |lwarpmk|:
% \begin{enumerate}
% \item When compiling the tutorial in \cref{sec:tutorial},
%	use the |lwarpmk| option for the \pkg{lwarp-newproject} package: \\
%	\hspace*{2em}|\usepackage[lwarpmk]{lwarp-newproject}|
% \item When the tutorial is compiled with |pdflatex|, the file |lwarpmk.lua|
%	will be generated along with the other configuration files.
% \item |lwarpmk.lua| may be used for this project:
%	\begin{description}
%		\item[Unix:] \
%			\begin{enumerate}
%			\item Make |lwarpmk.lua| executable: \userentry{chmod 0755 lwarpmk.lua}
%			\item Compile documents with
%				\userentry{./lwarpmk.lua html}
%				\userentry{./lwarpmk.lua print} \quad etc.
%			\item It may be useful to rename or link to a version without the |.lua| suffix.
%			\end{enumerate}
%		\item[Windows:] \
%
%			Compile documents with either of the following, depending
%			on which command shell is being used:
%			\userentry{texlua lwarpmk.lua html}
%			\userentry{texlua lwarpmk.lua print} \quad etc.
%
%			Or:
%
%			\userentry{lwarpmk html}
%			\userentry{lwarpmk print} \quad etc.
% 	\end{description}
% \end{enumerate}
%
%
% \subsection{Installing additional utilities}
%
% The \TeX\ utilities |latexmk| and |pdfcrop| may be provided by
% the installation of additional \TeX-relatex operating-system packages.
%
% The tools from the \textsc{Poppler} project may also be provided by your
% operating system's package-installation tools.
% For Windows, see \cref{tab:utility} on \cpageref{tab:utility}.
%
% Perl may require installation as well. See \cref{tab:utility}.
%
% \begin{description}
% \item [To test for the existence of the additional utilities:]
%	Enter the following in a command line:

% \subsection{Starting a new project}
%
% \changes{v0.21}{2017/02/23}{File \texttt{lwarp\_tutorial.txt} added.}
%
% \begin{enumerate}
%
% \item Create a new project directory called |tutorial|.

% \begin{description}
%
% \item [|tutorial.pdf|:] The \acro{PDF} output from \LaTeX.
%
% \item [|tutorial\_html.tex|:] A small |.tex| file used to create
%	a parallel \acro{HTML} version of the document, which co-exists with usual
%	the \acro{PDF} version, and which will have its
%	own auxiliary files.  In this way, both \acro{PDF} and \acro{HTML}
%	documents may co-exist side-by-side.
%

%	of the auxiliary files will also be generated.
%
% \item [|lwarpmk.conf|:] A configuration file for |lwarpmk|,

%	by the user.
%
% \item [|sample\_project.css|:] An example of a user-customized \acro{CSS} file,

% \subsection{Compiling the print version with \texttt{lwarpmk}}
%
% The |lwarpmk| utility program is used to compile either the printed or
% the \acro{HTML} version of the document.
%
% |lwarpmk print| is used to recompile a printed version of the document.
%
% \begin{enumerate}
%
% \item Re-compile the print version: \userentry{lwarpmk print}
%
%	|lwarpmk| prints an introduction then checks to see if the document
%	must be recompiled.  If it seems that the files are up-to-date, then
%	|lwarpmk| informs you of that fact and then exits.
%
% \item Make a small change in the original document,
%	such as adding a space character.
%
% \item Recompile again.  \userentry{lwarpmk print}
%
%	The document is recompiled when a change is seen in the source.
%	Several compilations may be necessary to resolve cross-references.
%
% \item Force a recompile to occur.
%
%	\userentry{lwarpmk again}
%	\userentry{lwarpmk print}
%
% |lwarpmk again| updates the date code for the file,
%	triggering a recompile the next time the document is made.\footnote{
%	Although, when using the utility |latexmk| (introduced later), the changed date is
%	ignored and an actual change in contents must occur to cause a recompile.}
%
% \item Process the index.
%	\userentry{lwarpmk printindex}
%
% \item Recompile again to include the index.
%	\userentry{lwarpmk print}
%
% \end{enumerate}
%
% Note that the \acro{HTML} customization commands are ignored while making the
% print version.
%
%
% \clearpage
%
% \subsection{Compiling the HTML version with \texttt{lwarpmk}}
%
% |lwarpmk html| is used to recompile an \acro{HTML} version of the document.
%
% \begin{enumerate}
% \item Compile the \acro{HTML} version:
%	\userentry{lwarpmk html}
%
%	\begin{enumerate}
%	\item |lwarpmk| uses \LaTeX\ to process |tutorial_html.tex|
%		to create \\
%		|tutorial_html.pdf|.
%	\item |pdftotext| is then used to convert into the file |tutorial_html.html|.
%		This file is a plain-text file containing \acro{HTML} tags and
%		content for the entire document.
%	\item |lwarpmk| manually splits |tutorial_html.html| into
%		individual \acro{HTML} files according to the \acro{HTML} settings.
%		For this tutorial, the result is |tutorial.html| (the home page),
%		along with |First-chapter.html|\footnote{
%			\texttt{First-chapter.html}
%			also contains the first section, even though the second
%			section is its own \acro{HTML} page.  This behavior is
%			controlled by the boolean \texttt{CombineHigherDepths}.},
%		|Some-math.html|, and the document's
%		index in |_Index.html|.\footnote{\texttt{index.html} is commonly
%		used as a homepage, so the document index is in \texttt{\_Index.html}.}
%	\end{enumerate}
%
% \item View the homepage in a web browser.
%
%	\qquad Open the file |tutorial.html| in a web browser.
%
%	Note that math is still displayed as its plain-text \LaTeX\ source
%	\margintag{math}
%	until the
%	images of the math expressions have not yet been generated.  Math may be
%	displayed as \acro{SVG} images or by a MathJax script, as seen in
%	\cref{sec:tutorialsvgmath,sec:tutorialmathjax}.
%
% \item Force a recompile:
%	\userentry{lwarpmk again}
%	\userentry{lwarpmk html}
%	\userentry{lwarpmk print}
%
% \item Process the \acro{HTML} index and recompile:
%	\userentry{lwarpmk htmlindex}
%	\userentry{lwarpmk html}
%
%	|_Index.html|, is updated for the new \LaTeX\ index.
%
% \item Reload the web page to see the added index.
% \end{enumerate}
%
%
%
% \clearpage
%
% \subsection{Generating the SVG images}
% \label{sec:tutorialsvgmath}
%
% By default \pkg{lwarp} represents math as \acro{SVG} images with
% \margintag{math as \acro{SVG} images}
% the \LaTeX\ source included in |alt| tags.  In this way,
% the math displays as it was drawn by \LaTeX, and the \LaTeX\ source
% may be copied and pasted into some other document.
%
% \pkg{lwarp} uses the same mechanism for |picture| and \tikz\ environments.
% \margintag{\env{picture} and \tikz}
%
% \begin{enumerate}
% \item Create the \acro{SVG} images:
%	\userentry{lwarpmk limages}
%	\userentry{lwarpmk html}
%
% \item Move to the tutorial's math page and reload.
%
% \item The math images are displayed using the same font and formatting
%	as the printed version.
%
% \item Copy/paste a math expression into a text editor to see the \LaTeX\ source.
% \end{enumerate}
%
% When a math expression, |picture|, or \tikz\ environment is added or
% \watchout[Adding/removing]
% removed, the \acro{SVG} images must be re-created with |lwarpmk limages|
% to maintain the proper image file sequence numbers.
%
% Expressing math as \acro{SVG} images has the advantage of representing
% the math exactly as \LaTeX\ would, but has the disadvantage of requiring
% an individual file for each math expression.
% \watchout[Lots of files!]
% There is no attempt at
% reusing the same file each time the same expression occurs, so each
% time \$x\$ is used, for example, yet another file is created.
% For a document with a large amount of math,
% see \cref{sec:tutorialmathjax} to use MathJax instead.
%
% \clearpage
%
% \subsection{Using MathJax for math}
% \label{sec:tutorialmathjax}
%
% Math may also be represented using the MathJax Javascript project.
% \margintag{math with MathJax}
%
% \begin{enumerate}
% \item In the tutorial's source code, change \\
%	\hspace*{2em} |\usepackage{lwarp}| \\
%	\hspace*{3em} to \\
%	\hspace*{2em} |\usepackage[mathjax]{lwarp}|
%
% \item Recompile \userentry{lwarpmk html}
%
% \item Reload the math page.
% \end{enumerate}
%
% MathJax requires web access unless a local copy of MathJax is available,
% \watchout[MathJax requirements]
% and it also requires that Javascript is enabled for the web page.
% The math is rendered by MathJax.  Right-click on math to see several
% options for rendering, and for copying the \LaTeX\ source.
%
% While using MathJax has many advantages, it may not be able to represent
% complex expressions or spacing adjustments as well as \LaTeX.
%
%
%
% \clearpage
% \subsection{Changing the CSS style}
%
% \DescribeMacro{\NewCSS}
% \cs{NewCSS} may be used to choose which |.css| file is used to display
% each section of the web page.  Use \cs{NewCSS} before |\begin{document}|
% to assign the style of the home page.
% If different parts of the website should have different styles,
% call \cs{NewCSS} again before each section heading which creates a new file.
%
% The styles provided by \pkg{lwarp} include:
% \begin{description}
% \item[|lwarp.css|:] A default style if \cs{NewCSS} is not used.  This
%	style is comparable to a plain \LaTeX\ document.
%	To set this style, you may use |\NewCSS{lwarp.css}|, or no \cs{NewCSS} call at all.
% \item[|lwarp\_formal.css|:] A formal style with a serif fonts and a traditional
%	look.
% \item[|lwarp\_sagebrush.css|:] A style with muted colors, gradient backgrounds,
%	additional borders, and rounded corners.
% \end{description}
%
% To see each style in use, change the \cs{NewCSS} entry in the tutorial
% |lwarpmk html|, and then reload the webpage.
%
% A customized style may also be created.
% \margintag{Custom \acro{CSS}}
% For each new project a file
% called |sample_project.css| is generated.  This may be renamed to
% |<project>.css| then used by assigning |\NewCSS{<project>.css|.
%
% Note that |sample_project.css| is overwritten whenever \pkg{lwarp-newproject}
% is loaded in print mode.
% It is therefore important to rename the file \watchout[Rename it!]
% to something like |<project>.css| before
% using it, so that your own changes are not overwritten.
%
% |<project>.css| has an entry which loads |lwarp.css|, and this
% entry may be changed to load |lwarp_formal.css| or |lwarp_sagebrush.css| if
% desired.  Additional changes to the \acro{CSS} may be made by making entries
% later in the |<project>.css| file.
%
% \clearpage
%
% \subsection{Customizing the HTML output}
% \label{sec:htmlsettings}
% \index{settings>HTML conversion}
% \index{HTML>conversion settings}
%
% Several settings may be used to customize the \acro{HTML} output.
% Watch for the correct placement of each!\watchout[Placement!]
%
% Note that if changes are made,
% \watchout[Changes!]
% it is best to first use |lwarpmk clearall| to
% clear all the \acro{HTML}, \acro{PDF}, and auxiliary files.
% Also, if \cs{HomeHTMLFilename}, \cs{HTMLFileName}, or \cs{UseLatexmk} are
% changed, it is necessary to reenable the |lwarp-newproject| package and
% then recompile the print version in order to recreate the configuration
% files for |lwarpmk|.
%
% \begin{description}
%
% \item[Placed in the preamble just before \pkg{lwarp} is loaded:] \
%
%	\begin{description}
%
% \ItemDescribeMacro{\HomeHTMLFilename} Filename of the homepage, without
%	the ``|.html|'' suffix.
%	Defaults to the \cs{BaseJobname}.  A common setting is: \\
%	\hspace*{2em}|\newcommand{HomeHTMLFilename}{index}| \\
%	causing the
%	homepage to be the file |index.html|.  Underscores are allowed in filenames.
%
% \ItemDescribeMacro{\HTMLFileName} A filename prefix for the rest of the \acro{HTML} web pages.
%	Useful for numbered web pages with a common prefix.  May be empty.
%
% \ItemDescribeMacro{\UseLatexmk} A macro which controls whether
%	\pkg{lwarp} uses |latexmk| to
%	compile the document.  This setting is written to |lwarpmk|'s configuration
%	files.  Defaults to false.  Set to true with: \\
%	\hspace*{2em}|\newcommand*{\UseLatexmk}{true}|
%
%	\end{description}
%
% \item[Placed in the preamble before \texttt{\cs{begin}\{document\}}:] \
%
%	\begin{description}
%
% \ItemDescribeCounter{tocdepth} Sectioning depth of the table of contents.
%	See \cref{sec:stackdepths} for a list of \LaTeX{} stack depths.
%
% \ItemDescribeCounter{SideTOCDepth} Sectioning depth of the side\acro{TOC}.
%	Defaults to 1, causing the sidetoc to show sections but not subsections.
%
%	Each subpage of the website has its own small table of contents
%	\margintag{sideTOC}
%	on the side (the ``side\acro{TOC}'').  Its depth is set by |SideTOCDepth|.
%	This side\acro{TOC} is only shown if the web page is wide enough.
%	When using a narrow web browser window,
%	``responsive web design'' is used to show the side\acro{TOC} at the top of the
%	page and a link back to ``Home'' at the bottom.
%
%	\label{sec:filedepth}
%	It is recommended to set: \\
%		\hspace*{.25in} |SideTOCDepth|\,=\,|FileDepth|, or \\
%		\hspace*{.25in} |SideTOCDepth|\,=\,|FileDepth|+1
%
%	If |SideTOCDepth|\,<\,|FileDepth|, web pages will be inaccessible via the
%	side\acro{TOC}.  \watchout
%	\index{files>inaccessible}
%	\index{pages>inacessible}
%	\index{missing sections}
%	\index{section>missing}
%
% \ItemDescribeCounter{FileDepth} Sectioning depth of file splits.
%	Defaults to -5, causing the entire \acro{HTML} website to be one single file.
%	\begin{itemize}
%	\item To place the entire file into one \acro{HTML} page, use: \\
%		\hspace*{.25in}|\setcounter{FileDepth}{-5}}|
%	\item To split the \acro{HTML} file at \cs{section} depth, use: \\
%		\hspace*{.25in}|\setcounter{FileDepth}{1}}|
%	\item To ensure that the \acro{HTML} pages/files are accessible:
%		\watchout\\
%		Place a \cs{tableofcontents} somewhere before the first section
%		break (therefore in the ``home page''), and set |tocdepth|\,>=\,|FileDepth|.
%		\index{files>inaccessible}
%		\index{pages>inacessible}
%		\index{missing sections}
%		\index{section>missing}
% 	\end{itemize}
%
% \ItemDescribeBoolean{CombineHigherDepths} Combine a higher section with
%	its first lower subsections, down to the |FileDepth|.
%	Defaults to true.  Set to false to simulate the concept of a chapter
%	opening on its own page, for example.
%
%	The file splits are controlled by the counter |FileDepth| and
%	the boolean |CombineHigherDepths|.
%	Setting |FileDepth| to 0 splits the file
%	at chapters, 1 at sections, etc.  |CombineHigherDepths| controls whether
%	to combine pages at levels higher than the chosen |FileDepth|, such as
%	in this tutorial where the page which opens the chapter also contains the
%	first section.
%	Be careful to set |tocdepth| and |SideTOCDepth| to allow
%	\watchout[Inaccesible pages!]
%	access to each page of the website.  Set |tocdepth| and |SideTOCDepth| to be
%	greater than or equal to |FileDepth|.
%
%	When making changes to the file structure,
%	\watchout[Lost in an old page!]
%	it is possible to end up
%	with the web browser pointing to an old file which is no longer in use.
%	When this occurs, changes to the web site will not appear in the browser,
%	even if reloading the page, because that page is no longer in use.
%	It is best to return to the home page, clean the files (|lwarpmk cleanall|),
%	change |FileDepth| and/or |CombineHigherDepths|, then finally recompile and
%	renavigate to the desired page using the new file structure.
%
% \ItemDescribeBoolean{FileSectionNames} If true, web page filenames are
%	derived from a sanitized version of the section names.  If false, web pages
%	are numbered.  Either way, the \cs{HTMLFileName} is prefixed.
%
%	Example HTML filenames:
%	\changes{v0.20}{2016/09/11}{Docs: Examples for generating HTML file names.}

%
% The following environments and macros are used to select actions which only apply

% or to \acro{HTML} generation.
%
% For most of built-in \LaTeX\ and many additional packages

% For those cases which \pkg{lwarp} does not handle by itself, the
% following environments and macros may be used to isolate sections
% of code for print-only or \acro{HTML}-only.
%
% These environments are also useful for creating a special version of
% the titlepage for print and another for \acro{HTML}.

% \DescribeEnv{warpHTML}
% Anything which is to be done only for \htmlfive{} output
% is surrounded by a |warpHTML| environment:
% \begin{Verbatim}[gobble=2,frame=lines,obeytabs,tabsize=4]

% \label{sec:printcommands}
%
% \changes{v0.14}{2016/03/26}{Docs: Commands into a warpprint environment.}
%
% Certain print-related commands should always be placed
% inside a \env{warpprint} environment, or may need other special handling.
% These are unrelated to \acro{HTML} output, but are hard to isolate automatically.
% For example:
%
% \begin{itemize}
% \item Paragraph formatting: \cs{parindent} \cs{parskip}
% \item Variable spaces such as \cs{vspace}.  \cs{hfill} is turned into a \cs{quad}.
%  Fixed spaces such as \cs{quad} are emulated correctly.
% \item Manual page positions such as the \pkg{textpos} package, which is
%	emulated but only in a limited way.
% \end{itemize}
%
% Some packages require additional setup commands.  Where these packages are emulated
% for \acro{HTML}, setup commands may work for the emulated \acro{HTML} output as well as for print
% output.  See the details for each package in this document for more information.

% \section{Expanding the code base}
% \pagestyle{pageheadfoot}
%
% Purely text-based packages probably will work as-is when generating
% \acro{HTML}.
%
% Look to existing code for ideas on how to expand into new code.
%
% An environment may be converted to a |lateximage| then displayed
% with an image of the resulting \LaTeX{} output.
% See \cref{sec:picture} for an example of the |picture| environment.
%
% To create a custom \acro{HTML} block or inline \acro{CSS} class,
% see \cref{sec:highlevelclasses}.
%
% \subsection{Creating an lwarp version of a package}
%
% When creating \acro{HTML},
% \pkg{lwarp} redefines the \cs{usepackage} and \cs{RequirePackage}
% macros such that it first looks to see if a |lwarp-<packagename>.sty|
% version exists.  If so, the \pkg{lwarp} version is used instead.
% This modular system allows the users to create their own
% versions of packages for \pkg{lwarp} to use for \acro{HTML}, simply by creating
% a new package with a |lwarp-| prefix.  If placed in the local
% directory along with the source code, it will be seen by that project
% alone.  If placed alongside the other |lwarp-| packages where \TeX\
% can see it, then the user's new package will be seen by any documents
% using \pkg{lwarp}.
%
% An |lwarp-<packagename>.sty| package is only used during \acro{HTML}
% generation.  Its purpose is to pretend to be the original package,
% while modify anything necessary to create a successful \acro{HTML} conversion.
% For many packages it is sufficient to simply provide nullified macros,
% lengths, counters, etc. for anything which the original package does,
% while passing the raw text on to be typeset.  See the pre-existing
% |lwarp-| packages for examples.
%
% Note that anything the user might expect of the original package
% must be replaced or emulated by the new |lwarp-| package, including
% package options, user-adjustable counters, lengths, and booleans, and
% conditional behaviors.
%
% Each |lwarp-| package should first call either \cs{LWR@ProvidesPackageDrop}
% or \cs{LWR@ProvidesPackagePass}.  If dropped, the original print-version
% package is ignored, and only the |lwarp-| version is used.
% Use this where the original print version is useless for \acro{HTML}.
% If passed, the original package is loaded first, with the supplied options, then
% the |lwarp-| version continues loading as well.  Use this when \acro{HTML}
% output only requires some modifications of the original package.
% For a case where the original package is usable as-is, there is no
% need to create a |lwarp-| version.

% \section{Implementation}
%
%
% This package is perhaps best described as a large collection of smaller
% individual technical challenges,
% in many cases solved through a number of \sout{crude hacks} clever tricks.
% Reference sources are
% given for many of the solutions, and a quick internet search will provide
% additional possibilities.
%
% Judgement calls were made, and are often commented.  Improvements are possible.
% The author is open to ideas and suggestions.
%
% Packages were patched for re-use where they provided significant functionality.
% Examples include \pkg{xcolor} with its color models and conversion to \acro{HTML}
% color output, and \pkg{siunitx} which provides many number and unit-formatting
% options, almost all of which are available in pure-text form, and thus
% easily used by \cmds{pdftotext}.
%
% Packages were emulated where their primary purpose was visual formatting which is not
% relevent to \acro{HTML} output.  For example, packages related to sectioning
% are already patched by numerous other packages, creating a difficult number of
% combinations to try to support, and yet in \acro{HTML} output all of the
% formatting is thrown away, so these packages are merely emulated.
%
% Packages with graphical output are allowed as-is, but must be nested inside a
% \env{lateximage} environment to preserve the graphics.
%
% There is still room to improve the factoring of the code, and doing so will become
% important if support for other output formats is added.  Rather than wait until the
% code is pristine, the author felt it best to publish early and accept input before
% pushing on towards a perhaps less-than-ideal solution.
%
%
% Testing has primarily been done with the Iceweasel/Firefox browser.
%
%
% \section{Stack depths}
% \label{sec:stackdepths}
% \index{HTML>headings}
% \index{section>depths}\index{stack depths}
%
% Stacks are created to track depth inside the \LaTeX{} document structure.
% This depth is translated to \acro{HTML} headings as shown
% in \cref{tab:depthsheadings}.
% ``Depth'' here is not
% depth in the traditional computer-science stack-usage sense, but rather a
% representation of the nesting depth inside the \LaTeX{} document structure.
%
% When starting a new section, the program first must close out any existing
% sections and lists of a deeper level to keep the \acro{HTML} tags nested correctly.
%
% \begin{table}
% \caption{Section depths and HTML headings\label{tab:depthsheadings}}
% \begin{tabular}{lcl}
% \toprule
% Section & \parbox[c]{.35in}{\LaTeX{} depth} & \acro{HTML} headings \\
% \midrule
% title of the entire website & & h1 \\
% none			& -5	& new for this package \\
% book			& -2	& \textbf{not yet used} \\
% part			& -1	& h2 \\
% chapter		& 0 	& h3 \\
% section		& 1		& h4 \\
% subsection	& 2		& h5 \\
% subsubsection	& 3		& h6 \\
% paragraph		& 4		& span class = "paragraph" \\
% subparagraph	& 5		& span class = "subparagraph" \\
% listitem		& 7		& new for this package, used for list items \\
% \bottomrule
% \end{tabular}
% \end{table}
%
% Support for the \pkg{memoir} package will require the addition of a \cmds{book}
% level, which will push the \acro{HTML} headings down a step, and also cause \cmds{subsubsection}
% to become a \cmds{div} due to a limit of six \acro{HTML} headings.
%
% It is possible to use \htmlfive{} \cmds{section} and \cmds{H1} for all levels,
% but this may not be well-recognized by older browsers.

% \codehtml
%    \begin{macrocode}
\begin{warpHTML}
%    \end{macrocode}



% Stacks are used to remember how to close sections and list items.
% Before a new section is started, previously nested sections and items must
% be closed out (un-nested) in proper order.
% Note that starting a new section may close several levels of previously
% \watchout
% nested items at the same time.
% For example, starting a new |\section| would close any currently open
% subsection, subsubsection, and paragraph.
% General environments are not nested on the stack since they have their own close
% mechanism.  List environments are nested, and items inside those environments
% are nested one level deeper still.
% List environments may be nested inside other list environments, and list items
% are nested inside list environments as well.  Thus, the stack may have items
% which are not necessarily in order, since a description may contain an enumerate,
% for example.
% Depths to be recorded in |\LWR@closedepthone|, etc.

% \subsection{Assigning depths}

% initial depths for empty stack entries:
%    \begin{macrocode}
\newcommand*{\LWR@depthnone}{-5}
%    \end{macrocode}
% all sectioning depths are deeper than |LWR@depthfinished|:
%    \begin{macrocode}

\newcommand*{\LWR@depthpart}{-1}
\newcommand*{\LWR@depthchapter}{0}
\newcommand*{\LWR@depthsection}{1}

\newcommand*{\LWR@depthsubsubsection}{3}
\newcommand*{\LWR@depthparagraph}{4}
\newcommand*{\LWR@depthsubparagraph}{5}

% used by |\itemize|, |\enumerate|, |\description|:

%    \end{macrocode}
% used by |\item|:
%    \begin{macrocode}
\newcommand*{\LWR@depthlistitem}{7}
%    \end{macrocode}

% \subsection{Closing actions}

% A stack to record the action to take to close each nesting level:
% Add more levels of stack if necessary for a very deeply nested document,
% adding to |\pushclose| and |\popclose| as well.
%    \begin{macrocode}

% \section{Paragraph handling}
% \label{sec:parhanding}
%
% These commands generate the HTML paragraph tags when allowed and
% required.
%
% Paragraph tags are or are not allowed depending on many conditions.
% \Cref{sec:parstartstop} has high-level commands which allow
% paragraph-tag generation to start/stop.
% Even when allowed (\cs{LWR@doingstartpars}),
% tags are not generated until a \LaTeX{} paragraph
% is being used (\cs{LWR@doingapar}).
% |LWR@lateximagedepth| is used to prevent nesting tags inside
% a |lateximage|.
% |LWR@spandepth| is used to prevent nesting paragraph tags inside
% a paragraph, which became important inside \cs{fbox} commands and other spans.

% Sectioning and cross-references have been emulated from scratch, rather
% than try to patch several layers of existing \LaTeX{} code and packages.
% Formatting is handled by \acro{CSS}, so the emulated code has much less
% work to do than the print versions.
%
% Section names and the resulting filenames with accented characters
% \margintag{Unicode}
% are partially supported, depending on the ability of
% |pdflatex| to generate characters and |pdftotext| to read them.
% If extra symbols appear in the text,

% it may be that |pdflatex| is actually producing a symbol over or under a
% character, resulting in |pdftotext| picking up the accent symbol separately.
%

% \section{Titles and the \protect\pkg{titling} package}
% \label{sec:titles}
% Supports and extends the \pkg{titling} package.
%
% Additional functions include \cs{published} and \cs{subtitle}, and the
% \cs{author} command has an additional \cs{affiliation} command to provide
% an affiliation and other additional information for each author in the
% title page.  The affiliation information is removed when using \cs{theauthor}
% in the main text.
%
% The \pkg{titling} package maintains the definitions of \cs{thetitle},
% \cs{theauthor}, etc., after the title has been typeset.
% These commands are to be used to refer to the document's title
% and author, etc., in the main text.
% These definitions
% have the \cs{thanks} and \cs{affiliation} removed, and for author the
% \cs{and} is replaced to generate a simple inline list of authors separated
% by commas.
%
% \cs{printtitle}, \cs{printauthor}, etc., are provided for use inside
% the \env{titlepage} or \env{titlingpage} environments, and these retain
% the \cs{thanks} and \cs{affiliation}.
%
% Several additional hooks are provided in addition to \pkg{titling}:
% \begin{description}
% \ItemDescribeMacro{\maketitlehookaa} Between ``published'' and the title.
% \ItemDescribeMacro{\maketitlehookaaa} Between the title and the subtitle.
% \ItemDescribeMacro{\prepublished} Before the ``published'' field.
% \ItemDescribeMacro{\postpublished} After the ``published'' field.
% \ItemDescribeMacro{\presubtitle} Before the subtitle.
% \ItemDescribeMacro{\postsubtitle} After the subtitle.
% \end{description}
%
% \DescribeMacro{\printthanks}
% \cs{printthanks} has been added to force the printing of thanks inside
% a \env{titlingpage} environment when \cs{maketitle} is not used.
%
% Inside a \cs{titlepage} or \cs{titlingpage} environment, use
% \cs{thanks} for footnotes, do not use \cs{footnote}.
% \watchout[No footnotes!]
%
% At the end of the \env{titlingpage} environment, footnote marks are forced to
% reset to zero.
%
% Inside a \env{titlingpage} environment with the |article| document class,
% thanks marks will be |fnsymbol| instead of |arabic|.  |arabic| is usually
% used when inside \env{titlepage} environments where the title page is
% on its own page, but is not automatically used
% inside a \env{titlingpage} environment.
%
% To force the thanks marks to
% be |arabic|:
% \begin{Verbatim}[gobble=2,frame=lines,obeytabs,tabsize=4]
% \begin{titlingpage}
% \thanksmarkseries{arabic}
% ...
% \end{Verbatim}
%
%
%
% \subsection{Setting the title, etc.}
%
% The following provide setting commands for both \acro{HTML} and print outputs.
%
% \DescribeMacro{@published}
% \DescribeMacro{@title}
% \DescribeMacro{@subtitle}
% \DescribeMacro{@author}
% \DescribeMacro{@date}
% \cs{@title}, \cs{@subtitle}, \cs{@author}, etc.\ store the values
% as originally assigned, including any \cs{thanks}, \cs{and}, or \cs{affiliation}.
% These are low-level macros intended to be used by other macros
% only inside a \env{titlepage} or \env{titlingpage},
% and are used by \cs{maketitle}.
% The author is printed inside a single-column table,
% which becomes multiple single-column tables if multiples authors are included.
%
% \DescribeMacro{\printpublished}
% \DescribeMacro{\printtitle}
% \DescribeMacro{\printsubtitle}
% \DescribeMacro{\printauthor}
% \DescribeMacro{\printdate}
% \cs{printtitle}, \cs{printsubtitle}, etc.\ are user-level macros intended to
% be used in \env{titlepage} and \env{titlingpage} environments in cases where
% \cs{maketitle} is not desired.  These commands preserve the \cs{thanks}, etc.,
% and should not be used in the main text.
% The author is printed inside a single-column table,
% which becomes multiple single-column tables if multiples authors are included.
%
% \DescribeMacro{\thepublished}
% \DescribeMacro{\thetitle}
% \DescribeMacro{\thesubtitle}
% \DescribeMacro{\theauthor}
% \DescribeMacro{\thedate}
% \cs{thetitle}, \cs{thesubtitle}, \cs{theauthor}, etc.\ are user-level
% sanitized versions which have removed the \cs{thanks} and \cs{affiliation},
% and \cs{and} is changed for inline text usage.
% The author is printed inline without \cs{affiliation} or \cs{thanks},
% with \cs{and} placing commas between multiple authors.
% Thus, these commands are to be used in the main text whenever the user
% wishes to refer to the document's title and such.  One practical use for this
% is to place the authors at the bottom of each \acro{HTML} page, such as:
%
% \DescribeMacro{\SetPageBottom} \marg{text}
% \begin{Verbatim}[gobble=2,frame=lines,obeytabs,tabsize=4]
% \SetPageBottom{
% \begin{center}\textcopyright~2016 \theauthor\end{center}
% }
% \end{Verbatim}


%
% \DescribeMacro{\author} \marg{author}
% \DescribeMacro{\and}
% While using \cs{maketitle}, the author is treated as a single-column table
% and the \cs{and} feature finishes the current table then starts a new one for
% the next author.  Each author thus is placed into its own table, and an
% affiliation may be placed on its own line such as
%
% |\author{Name \\ Affiliation \and Second Name \\ Second Affiliation}|
%
% After \cs{maketitle} has completed, \cs{theauthor} retains the definition of
% the author, but \cs{and} is changed to become a comma and a space, intending to
% print the authors names separated by spaces.  This fails when affiliations are
% included on their own table rows.
%
% A solution, provide here, is to define a macro \cs{affiliation} which
% during \cs{maketitle} starts a new table row and adds the affiliation,
% but after \cs{maketitle} is finished \cs{affiliation} is re-defined
% to throw away its argument, thus printing only the author names
% when \cs{author} is later used inline.
%
%
% \begin{macro}{\affiliation} \marg{text}
%
% Adds the affiliation to the author for use in \cs{maketitle}.
% Nullified when later used for inline use of \cs{theauthor}.
%
% \codehtml
%    \begin{macrocode}
\begin{warpHTML}

% Uses \acro{CSS} |vertical-align:middle| so that top or bottom-aligned cells may go above or below this cell.
% \item [p:] Converted to table cells with paragraph tags.
% Ref: \Cref{tab:baseline},
% \LaTeX{} places the top line of a parbox
% aligned with the rest of the text line, so \acro{CSS} |vertical-align:bottom| is used to
% have the \acro{HTML} result appear with the paragraph extending below the L, R, C cells at the middle, if possible.
% This may be confusing as a P cell may not top-align with an L,R,C cell in the \acro{HTML}
% conversion, especially in the presence of a B cell, and two P cells side-by-side will
% be aligned at the bottom instead of the top.
% Some adjustment of the \acro{CSS} may be desired, changing
% |td.tdp|, |td.tdP|, |td.tdprule|, and |td.tdPrule| to |vertical-align: middle|.
% Another possibility is to change L,R,C, and P to |vertical-align: top| and not worry
% about the alignment of B and M cells or trying to approximate \LaTeX{} baselines.
% \item [m:] With paragraph tags, \acro{CSS} |vertical-align:middle|.
% \item [b:] With paragraph tags, \acro{CSS} |vertical-align:top| so that the bottom of the
% text is closest to the middle of the text line.
% \item [P, M, B:] Horizontally-centered versions,
% \item [S:] Converted to 'r'.  From the \pkg{siunitx} package.

% \section{Floats}
% \label{sec:floats}

% Floats are supported, although partially through emulation.
%
% \Cref{tab:floatdata} shows the data structure associated with each |<type>|
% of float.

% \changes{v0.14}{2016/03/28}{Docs: Table: Float data structures.}
% \begin{table}
% \caption{Float data structures\label{tab:floatdata}}
%
% \bigskip
% For each |<type>| of float (figure, table, etc.) there exists the following:
%
% \hrule
% \begin{description}
% \item [counter <type>:] A counter called |<type>|, such as |figure|, |table|.
% \item [\cs{<type>name}:] Name.  \cs{figurename} prints ``Figure'', etc.%
% \item [\cs{ext@<type>}:] File extension.  \cs{ext@figure} prints ``lof'', etc.
% \item [\cs{fps@<type>}:] Placement.
% \item [\cs{the<type>}:] Number.  \cs{thetable} prints the number of the table, etc.
% \item [\cs{p@<type>}:] Parent's number.
%	Prints the number of the [within] figure, etc.
% \item [\cs{fnum@<type>}:] Prints the figure number for the caption. \\
%	\cs{<type>name}~\cs{the<type>}, ``Figure 123''.
% \item [\cs{<type>}:] Starts the float environment. |\figure| or \cs{begin}|{figure}|
% \item [\cs{end<type>}:] Ends the float environment. |\endfigure| or \cs{end}|{figure}|
% \item [\cs{tf@<ext>}:] The \LaTeX{} file identifier for the output file.
% \item [\texttt{LWR@have<type>}:] A boolean rememebering whether a \cs{listof} was
%	requested for a float of this type.
% \item [File with extension lo<f,t,a-z>:] An output file containing
%	the commands to build the
%	\cs{listof}{<type>}{<name>} ``table-of-contents'' structure.
% \item [Cross-referencing names:] For \pkg{cleveref}'s \cs{cref} and related,
%	\cs{crefname} and \cs{Crefname} assign human-readable names for references to this float type.
% \end{description}

% This page number is used to generate an |autofloat| \acro{HTML} \acro{ID}
% in the \acro{HTML} output at the start of the new \acro{HTML} file.
% Meanwhile, there is a float counter used to generate an \acro{HTML} |autofloat|
% \acro{ID}s at the start of the float itself in the \acro{HTML} file.
% The |autopage| and |autofloat| values to use for each float are written to the
% |.lof|, etc. files just before each float's entry.  These values are used
% by \cs{l@figure}, etc. to create the \acro{HTML} links in the List of Figures, etc.

% \section{Lateximages}

% A |\lateximage| is typeset on its own \acro{PDF} page inside an \acro{HTML} comment starting on the preceeding page
% and ending on following page, and instructions are written to
% |lateximage.txt| for |lwarpmk| to extract the |\lateximage| from the page of the \acro{PDF} file
% then generate an accompanying |.svg| file image file.  Meanwhile, instructions to
% show this image are placed into the \acro{HTML} file after the comment.
%
% Since the |\lateximage| is placed onto its own \acro{PDF} page, which |pdftotext| will read
% and try to convert to text, an \acro{HTML} open comment is placed onto the bottom of the current
% page, but it must appear below any footnotes on the current page, so
% a special page style (|LWR@commentfooterstyle|) is used.
%
% An \acro{HTML} span is created to hold both the \acro{HTML} comment which will have the |pdftotext| conversion,
% and also the link to the final |.svg| image.

% \section{Cleverref}
% \label{sec:cleveref}

% \DescribePackage{cleveref}
% \pkg{cleveref} package is used as-is with minor patches.
%
% \pkg{cleveref} and the following associated macro patches are
% \margintag{loading order}
% automatically preloaded at the end of the preamble via \cs{AtEndPreamble}
% and \cs{AfterEndPreamble}.
% This is done because the \acro{HTML} conversion requires \pkg{cleveref}.
% The user's document may not require \pkg{cleveref}, thus the user
% may never explicitly load it, so during \acro{HTML} output \pkg{lwarp} loads it last.
% If the user's document preamble uses \pkg{cleveref} options, or functions such as
% \cs{crefname}, then \pkg{cleveref} may be loaded in the user's preamble near the
% end, and \pkg{lwarp}'s additional loading of \pkg{cleveref} will have no effect.
%
% \Cref{tab:crossrefdata} on \pageref{tab:crossrefdata}
% shows the data structure of the label/reference system
% as revised by \pkg{lwarp} and \pkg{cleveref}.


% A few patches allow \pkg{cleveref} to work as-is:

% \index{minipage>horizontal space between}
% \index{space>horizontal between minipages}
% \index{horizontal space>between minipages}
% Minipages are often placed side-by-side inside figures, with a bit of
% horizontal space to separate them.  Since \acro{HTML} does not allow
% a |div| to be inside a |p|, paragraphs must be turned off during the
% generation of the minipage, then turned on after the minipage is complete.
% When this occurs between side-by-side minipages, |lwarp| correctly
% surpresses the paragraph tags between the minipages, unless some other
% text is between the minipages.  Such text forms its own paragraph, resulting
% in text after a minipage to be on its own line.  Since people often place
% \DescribeMacro{\hspace}
% \DescribeMacro{\enskip}
% \DescribeMacro{\quad}
% \DescribeMacro{\qquad}
% small horizontal space between minipages, it is desirable to maintain this
% space if possible.  |lwarp| tries to do this by remembering that a minipage
% has been seen, in which case paragraph tags are surpressed around
% \cs{hspace}, \cs{enskip}, \cs{quad}, and \cs{qquad} until the end of the paragraph, when
% the closing |p| tag is created.
%
% When a minipage is seen, the boolean
% |LWR@minipagethispar| is set, telling the following horizontal
% whitespace commands to try to surpress their surrounding paragraph
% tags.  |LWR@minipagethispar| is cleared at the next
% end of paragraph, when the \acro{HTML} paragraph closing tag is

% \changes{v0.20}{2016/12/20}{\pkg{lwarp-newproject}: Added.}
%
% \section{lwarp-newproject}
%
% \DescribePackage{lwarp-newproject}
% \pkg{lwarp-newproject} is used to create lwarp-specific
% system files in a new project.
%
% \DescribeOption[lwarp-newproject]{warpprint} Configuration files are only
%	created if the |warpprint| option was used.  When this is the case,
%	\pkg{lwarp-newproject} knows that \cs{jobname} is the source code's filename
%	(as opposed to the |<project>_html.tex| filename).
%
% \DescribeOption[lwarp-newproject]{warpHTML} Does not create configuration files.
%	|warpprint| or |warpHTML| are passed to both \pkg{lwarp} and
%	\pkg{lwarp-newproject} by |lwarpmk|, depending on whether |lwarpmk print|
%	or |lwarpmk html| was used.
%
% \DescribeOption[lwarp-newproject]{BaseJobName} |BaseJobname=somename| sets
%	\cs{BaseJobname} to |somename|, which is used to set \cs{HomeHTMLFileName},
%	which is then written to the |lwarpmk.conf| and |<project>.lwarpmkconf|
%	configuration files.
%
%	\cs{BaseJobname} is also written to |<project>_html.tex| as an option
%	given for the \pkg{lwarp} and \pkg{lwarp-newproject} packages during the
%	creation of \acro{HTML} output.
%
%	\cs{BaseJobname} is the \cs{jobname} of the printed version, even while compiling
%	the \acro{HTML} version, where \cs{jobname} has |_html| appended.
%
% \DescribeOption[lwarp-newproject]{lwarpmk} Tells |lwarp-newproject| to
%	generate a local copy of |lwarpmk| called |lwarpmk.lua|.
%	Useful for archiving for future use.
%	This file may be made executable and acts just like |lwarpmk|.
%
% In the document source:
% \begin{Verbatim}[gobble=2,frame=lines,obeytabs,tabsize=4,formatcom={\unskip}]
% \documentclass{article} % or book, report
% ...
% (font selection, input encoding)
% ...
% \newcommand*{\HomeHTMLFileName}{index}, or {projectname}
% \newcommand*{\HTMLFileName}{}
% \usepackage{lwarp-newproject}
% \usepackage{lwarp}
% ...
% (load other packages, the rest of the preamble)
% ...
% \NewCSS{project.css}
% \NewHTMLdescription{Summarize this webpage.}
% ...
% \begin{document}
% ...
% \end{document}
% \end{Verbatim}
%
% Place |\usepackage{lwarp-newproject}| just before |\usepackage{lwarp}| in the
% document source.  The operating system and \TeX\ engine will be auto-detected,
% and a customized |lwarpmk.conf| file will be generated, along with
% the other support files (|*.css|, |lwarp_html.xdy|, |lwarp_mathjax.txt|).
% Rename |sample_project.css| to your own custom |projectname.css| and
% edit it if desired.
%
% After the first compile, |\usepackage{lwarp-newproject}|
% may be commented out unless the configuration changes.
% For example, it may be re-enabled
% to switch between |pdflatex|, |xelatex|, and |lualatex|, in which case
% a new manual compile (without using |lwarpmk|) will auto-configure and
% regenerate the files.  It may also be left enabled at all times, in which case
% the configuration files will be regenerated each time.  Note that your own
% |projectname.css| file will not be over-written by the newly regenerated
% |sample_project.css|.
