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.
\watchout[warnings]

\codehtml\vspace*{5.25ex}\ignorespaces
\codeprint\vspace*{5.25ex}\ignorespaces
\codeall\vspace*{5.25ex}\ignorespaces
Green-colored tags in the left margin show which sections of source
code apply to the generation of \HTML, print, or both forms of output.
}

\newcommand{\limitspageref}{\pkg{cleveref} and \pkg{varioref} are supported,
but printed page numbers do not map to \HTML, so a section name or a text phrase
are used instead.
See \cref{sec:successfulcommands} to redefine the message which is printed
for page number references.
}

\newcommand{\limitshyperlinks}{%
\pkg{lwarp} emulates \pkg{hyperref}, including the creation of active hyperlinks,
but does not require that \pkg{hyperref} be loaded by the document.

\pkg{lwarp} can also load \pkg{url}, but \pkg{url} should not be used at the
same time as \pkg{hyperref}, since they both define the \cs{url} command.
\pkg{lwarp} does not (yet) attempt to convert \pkg{url} links into hyperlinks
during \HTML\ output, nor does \pkg{url} create hyperlinks during print output.
}

\newcommand{\limitsabstract}{%
\pkg{abstract} is supported.
If using the \texttt{number} option with file splits,
be sure to place the table of contents before the abstract.
The number option causes a section break which
may cause a file split, which would put a table of contents out
of the home page if it is after the abstract.
}



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

\newcommand{\limitshspace}{%
\DescribeMacro{\hspace}%
\index{space>horizontal}%
\index{horizontal space}%
\cs{hspace} is converted to an inline \HTML\ span of the given width,
except that \texttt{0} width is ignored,
a width of \texttt{.16667em} is converted to
an \HTML\ thin breakable space (\texttt{U+2009}),
and a \cs{fill} is converted to a \cs{qquad}.

\index{\texttt{\textasciitilde}}%
\DescribeMacro{\,}%
\texttt{\~} and \cs{,} are converted to \HTML\ entities.

\DescribeMacro{\kern}%
\DescribeMacro{\hskip}%
\cs{kern} and \cs{hskip} are treated as a single normal space.
}

\newcommand{\limitsreferences}{%
\cs{nameref} refers to the most recently-used section where the \cs{label}
was defined.  If no section has been defined before the \cs{label},
the link will be empty.
Index entries also use \cs{nameref} and have the same limitation.
}

\newcommand{\limitsfootnotes}{
\pkg{lwarp} uses native \LaTeX\ footnote code, although with its own
\cs{box} to avoid the \LaTeX\ output routine.  The usual functions work as-is.
}

\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 \HTML\ output.  To combine the two so that
\cs{attrib} is used for print and \cs{attribution} is used for \HTML:

\begin{docsidebar}
\raggedright
\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 \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 layout
(\texttt{-layout} option) of the
text in the \HTML-tagged \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 \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}{%

\limitsntheoremnumbering

Math may be rendered
\margintag{Math rendering}
as \SVG\ graphics or using the \textsc{MathJax} JavaScript display engine.
\index{JavaScript>MathJax}

For \SVG\ math,
\margintag{SVG math option}
math is rendered as usual by \LaTeX{} into the initial \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 \PDF\ and converted to \SVG\ graphics
via a number of utility programs.
The \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 \HTML\ \attribute{alt} attribute 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 \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 \SVG\ files directly into the \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 \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 \SVG\ files are also larger as well.

Conversion to \MathML\ might be a better approach,
\margintag{MathML}
among other things
allowing a more compact representation of math than \SVG\ drawings.
Problems with \MathML\ include limited browser support and some
issues with the fine control of the appearance of the result.
Also see \cref{sec:epub} regarding \EPUB\ output with MathJax.

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\ \PDF\ output placed inside an \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 \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 \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]

    \href{https://github.com/mathjax/MathJax-third-party-extensions/tree/master/siunitx}
        {\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{\limitsntheorem}{%
This conversion is not total.
\watchout[Font control]
Font control is via \CSS, and the custom \LaTeX\ font settings
are ignored.

\limitsntheoremnumbering
}

\newcommand{\limitsntheoremnumbering}{%
\pkg{ntheorem} has a bug with equation numbering in \AmS\ environments%
\watchout[Equation numbering]%
\index{equation>miss-numbered}%
\index{split>miss-numbered}%
\index{AMSmath>split miss-numbered}
when the option \texttt{thref} is used.  \pkg{lwarp} does not share
this bug, so equations with \cs{split}, etc, are numbered correctly
with \pkg{lwarp}'s \HTML\ output, but not with the print output.
It is recommended to use \pkg{cleveref} instead of \pkg{ntheorem}'s
\texttt{thref} option.
}


\newcommand{\limitsgraphics}{%
If using the older \pkg{graphics} syntax, use both optional arguments
\watchout[\pkg{graphics} vs. \pkg{graphicx}]
for \cs{includegraphics}.
A single optional parameter is interpreted as the newer \pkg{graphicx} syntax.
Note that viewports are not supported by \pkg{warp};
\watchout[viewports]
the entire image will be shown.

\cs{graphicspath} only works for a single directory;
\watchout[\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 \HTML\ output, \cs{includegraphics} accepts an optional
\margintag{\HTML\ class}
\texttt{class=xyz} keyval combination, and if this is given then
the \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 \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.
}

\newcommand{\limitssvgimages}{%
When a math expression, \texttt{picture}, or \tikz\ environment is added or
\watchout[Adding/removing]
removed, the \SVG\ images must be re-created with \texttt{lwarpmk limages}
to maintain the proper image file sequence numbers.

If \HTML\ appears where an \SVG\ image should be,\watchout[\HTML\ instead of images]%
\index{math>showing as HTML}%
\index{images>showing as HTML}%
\index{SVG>images showing as HTML}%
\index{HTML>in place of SVG images}
recompile the document one more
time to get the page numbers back in sync, then remake the images one more time.

Expressing math as \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 \texttt{\$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.
}

\newcommand{\limitsxcolor}{%
\cs{colorboxBlock} and \cs{fcolorboxBlock} are provided for
\margintag{\cs{colorboxBlock} and \cs{fcolorboxBlock}}
increased \HTML\ compatibility, and they are identical to
\cs{colorbox} and \cs{fcolorbox} in print mode.  In \HTML\ mode
they place their contents into a \element{div} instead of a \element{span}.
These \element{div}s are set to \attribute{display:~inline-block} so
adjacent \cs{colorboxBlock}s appear side-by-side in \HTML, although
text is placed before or after each.

Print-mode definitions for \cs{colorboxBlock} and \cs{fcolorboxBlock}
are created by \pkg{lwarp}'s core if \pkg{xcolor} is loaded.

\cs{fcolorbox} and \cs{fcolorboxBlock} allow a background color of \texttt{none},
\margintag{background: \texttt{none}}
in which case only the frame is drawn, which can be useful for \HTML.

Color definitions, models, and mixing are fully supported

without any changes required.

Colored tables are ignored so far.  Use \CSS\ to style tables.
\margintag{tables}

\cs{textcolor}, \cs{colorbox}, and \cs{fcolorbox} are supported.

    if a ``misplaced \cs{noalign}'' error occurs,
    change \\
    \hspace*{.375in}\cmds{This \& That \cs{endhead}} \\
    to \\
    \hspace*{.375in}\cmds{\cs{warpprintonly}\{This \& That \cs{endhead}\}} \\
    and likewise with the other \cs{end} headings.
    Keep the \cs{endfirsthead} row unchanged, as it is still relevent to \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 \HTML\ output, though, anything placed inside
    braces is not seen by \pkg{lwarp}'s tabular handling algorithm.
    To resolve this problem, make a copy of the row, with one version
    for print output, containing the extra braces, and another version
    for \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\}} \\
    \hspace*{.375in} \cs{warpHTMLonly}\{\texttt{1 \& 2 \& \cs{multirow}\{2\}\{2cm\}\{Text\} \& 3 \textbackslash\textbackslash\}}

\end{itemize}
}

\newcommand{\limitslongtable}{%
Longtable \cs{endhead}, \cs{endfoot}, and \cs{endlastfoot} rows are
not used for \HTML, and these rows should be disabled.
\watchout
Use
    \begin{sourcedisplay}
    \cs{warpprintonly}\{row contents\}
    \end{sourcedisplay}
instead of
    \begin{sourcedisplay}
    \cs{begin}\{warpprint\} \ldots\ \cs{end}\{warpprint\}
    \end{sourcedisplay}
Doing so helps avoid ``Misplaced \cs{noalign}.'' when using \cs{begin}\{warpprint\}.

Keep the \cs{endfirsthead} row, which is still relevent to \HTML\ output.

\cs{kill} is ignored, place a \cs{kill} line inside
\watchout
    \begin{sourcedisplay}
    \cs{begin}\{warpprint\} \ldots\  \cs{end}\{warpprint\}
    \end{sourcedisplay}
or place it inside \cs{warpingprintonly}.
}

\newcommand{\limitssaveboxes}{%
\LaTeX\ boxes are placed inline and do not allow line breaks, so boxes
with long contents may overflow the line during \HTML\ conversion.
This is mostly a problem when the boxes contain objects which themselves
hold large \HTML\ tags, such as rotation commands with long contents.
When this object overflows the line, some \HTML\ code will be lost and 
the page will be corrupted.
}

\newcommand{\limitsminipage}{%
A line of text with an inline minipage
\watchout[inline]
or parbox will have the minipage or parbox placed onto its own line,
because a paragraph is a block element and cannot be made \texttt{inline-block}.

Minipages and parboxes will be placed side-by-side in \HTML\
\margintag{placement}
unless you place a \cs{newline} between them.

Side-by-side minipages may be separated by \cs{quad}, \cs{qquad}, \cs{enskip},
\margintag{side-by-side}
\cs{hspace}, \cs{hfill}, or a \cs{rule}.
When inside a \texttt{center} environment, the result is
similar in print and \HTML.  Paragraph tags are surpressed between
side-by-side minipages and these spacing commands, but not at the start or end
of the paragraph.

There is limited support for minipages inside an \HTML\ \element{span}.
\margintag{in a span}
An \HTML\ \element{div} cannot appear inside a \element{span}.
While in a \element{span}, minipages, and parboxes, and any enclosed lists
have limited \HTML\ tags, resulting in an ``inline'' format, without markup
except for \HTML\ breaks.
Use \cs{newline} or \cs{par} for an \HTML\ break.

When using \cs{linewidth}, \cs{textwidth}, and \cs{textheight},
\margintag{size}
widths and heights are scaled proportionally to a 6\texttimes{}9 inch text area.

A minipage of width exactly \cs{linewidth} is automatically
given no \HTML\ width.
\margintag{no-width minipages}

A new macro \cs{minipagefullwidth} requests
\margintag{full-width minipages}
that the next minipage be generated
without an \HTML\ \attribute{width} attribute, 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 \HTML,
whereas in regular \LaTeX{} \PDF\ output they do not.
\watchout[text alignment]
Use a \env{flushleft} or similar environment in the child minipage
to force a text alignment.
}

\newcommand{\limitsfancybox}{%
\pkg{fancybox}'s documentation has an example \env{FramedEqn} environment
\margintag{framed equation example}
which combines math, \cs{Sbox}, a minipage, and an \cs{fbox}.
This combination requires that the entire
environment be enclosed inside a \env{lateximage}, which is done by
adding \cs{lateximage} at the very start of \env{FramedEqn}'s beginning code, and
\cs{endlateximage} at the very end of the ending code.
Unfortunately, the \HTML\ \attribute{alt} attribute is not used here.
\begin{sourcedisplay}
\cs{newenvironment}{FramedEqn} \\
\{ \\
\cs{lateximage}\% NEW \\
\cs{setlength}\{\cs{fboxsep}\}\{15pt\} \\
\dots\}\{\dots\\
\cs{[}\cs{fbox}\{\cs{TheSbox}\}\cs{]} \\
\cs{endlateximage}\% NEW \\
\}
\end{sourcedisplay}

\cs{fbox} works with \pkg{fancybox}.
\margintag{framing alternatives}
Also see \pkg{lwarp}'s \cs{fboxBlock} macro and \env{fminipage} environment for
alternatives to \cs{fbox} for framing environments.

The \pkg{fancybox} documentation's example framed table
\margintag{framed table example}
using an \cs{fbox} containing a \env{tabular}
does not work with \pkg{lwarp}, but the \env{FramedTable} environment does work if
\cs{fbox} is replaced by \cs{fboxBlock}.  This method loses \HTML\ formatting.
A better method is to enclose the table's contents inside a \env{fminipage} environment.
The caption may be placed either inside or outside the \env{fminipage}:
\begin{sourcedisplay}
\cs{begin}\{table\}\\
\cs{begin}\{fminipage\}\{\cs{linewidth}\}\\
\cs{begin}\{tabular\}\{lr\}\\
...\\
\cs{end}\{tabular\}\\
\cs{end}\{fminipage\}\\
\cs{end}\{table\}\\
\end{sourcedisplay}

\pkg{lwarp} does not support the \env{verbatim} environment inside a span, box,
\margintag{framed verbatim}
or \pkg{fancybox}'s \cs{Sbox}, but a \env{verbatim} may be placed inside
a \env{fminipage}.  The \pkg{fancybox} documentation's example \env{FramedVerb}
may be defined as:
\begin{sourcedisplay}
\cs{newenvironment}\{FramedVerb\}[1] \% width\\
\{\\
\cs{VerbatimEnvironment}\\
\cs{fminipage}\{\#1\}\\
\cs{begin}{Verbatim}\\
\}\{\\
\cs{end}{Verbatim}\\
\cs{endfminipage}\\
\}
\end{sourcedisplay}


\pkg{fancybox}'s \cs{VerbBox} may be used inside \cs{fbox}.
\margintag{framed \cs{VerbBox}}
}

\newcommand{\limitsmdframed}{%
Most basic functionality is supported, including
\margintag{support}
frame background colors and single-border colors and thickness,
title and subtitle background colors and borders and thickness,
border radius, and shadow.
CSS classes are created for \pkg{mdframed} environments and frame titles.

When used, \pkg{lwarp} loads \pkg{mdframed} in \HTML\ with \texttt{framemethod=none}.
\watchout[loading]

For title font, use
\margintag{font}%
\begin{sourcedisplay}
frametitlefont=\cs{textbf},
\end{sourcedisplay}
instead of
\begin{sourcedisplay}
frametitlefont=\cs{bfseries},
\end{sourcedisplay}
where \cs{textbf} must appear just before the comma and will receive the
following text as its argument (since the text happens to be between braces
in the \pkg{mdframed} source).
Since \pkg{lwarp} does not support \cs{bfseries} and friends,
only one font selection may be made at a time.

\texttt{theoremtitlefont} is not supported, since the following text is not
\margintag{theoremtitlefont}
in braces in the \pkg{mdframed} source.

Footnotes are currently placed at the bottom of the \HTML\ page.
\margintag{footnotes}

\texttt{userdefinedwidth} and \texttt{align} are currently ignored.

\newcommand{\limitscaption}{%
To ensure proper float numbering, set caption positions
such as:

\begin{sourcedisplay}
\cs{captionsetup}[table]\{position=top\} \\
\cs{captionsetup}[figure]\{position=bottom\}

Similarly for \texttt{subtable}, \texttt{subfigure},
and \texttt{longtable}.
}

\newcommand{\limitscombiningfloats}{%
If using \cs{newfloat}, \pkg{trivfloat}, and/or
\pkg{algorithmicx} together, see \cref{sec:combiningfloats}.
\watchout[package conflicts]
}

\newcommand{\limitssubfig}{%
% At present, subfigures before the enclosing figure/table's \cs{caption}
% \margintag{LOF/LOT}
% would appear in the List of Figures/Tables before the enclosing figure/table,
% therefore \pkg{lwarp} does not place subfigures in the LOF/LOT.

At present, the package options for \texttt{lofdepth} and \texttt{lotdepth}
\watchout[\texttt{lof/lotdepth}]
are not working.  These counters must be set separately after the
package has been loaded.

In the document source, use \cs{hfill} and \cs{hspace*}
\margintag{horizontal spacing}
between subfigures to spread them
apart horizontally.  The use of other forms of whitespace may
cause paragraph tags to be generated, resulting in subfigures
appearing on the following lines instead of all on a single line.
}

\newcommand{\limitsfloatrow}{%
When combined with the \pkg{subfig} package,
\watchout[\pkg{subfig} package]
while inside a \env{subfloatrow} \cs{ffigbox} and \cs{ttabbox}
must have the caption in the first of the two of the mandatory arguments.

The emulation of \pkg{floatrow} does not support \cs{FBwidth} or \cs{FBheight}.
These values are pre-set to \texttt{.3\cs{linewidth}} and \texttt{2in}.
\watchout[\cs{FBwidth}, \cs{FBheight}]
Possible solutions include:
\begin{itemize}
\item Use fixed lengths.  \pkg{lwarp} will scale the \HTML\ lengths appropriately.
\item Use \env{warpprint} and \env{warpHTML} environments to select appropriate
    values for each case.
\item Inside a \env{warpHTML} environment, manually change
    \cs{FBwidth} or \cs{FBheight} before the \cs{ffigbox} or \cs{ttabbox}.
    Use \cs{FBwidth} or \cs{FBheight} normally afterwards; it will be used as
    expected in print output, and will use your custom-selected value in \HTML\
    output.  This custom value will be used repeatedly,
    until it is manually changed to a new value.
\end{itemize}
}

\newcommand{\limitssiunitx}{%
Do not use \cmds{per-mode=fraction}, which cannot be seen by the final \cmds{pdftotext} conversion.
\watchout[per-mode]

Place the \cs{SI} expression inside math mode for anything which requires math mode units.
}

\newcommand{\limitsnicefrac}{%
\pkg{units} and \pkg{nicefrac} work as-is with \pkg{lwarp}, but
MathJax does not have an extension for \pkg{units} or \pkg{nicefrac}.
These packages do work with \pkg{lwarp}'s option \texttt{svgmath}.
}


% \newcommand{\limitsbabelone}{%
% If using \pkg{babel} with French, use
% \watchout[French]%
% \begin{sourcedisplay}
% \cs{frenchbsetup\{StandardLists=true\}}
% \end{sourcedisplay}
% to preserve the special \HTML\ and list handling.
% }

\newcommand{\limitsbabeltwo}{%
When French is used, the caption separator is
\margintag{\cs{CaptionSeparator}}
changed to a dash.  The following may be used to restore it to a colon:
\begin{sourcedisplay}
\texttt{\cs{renewcommand}*\{\cs{CaptionSeparator}\}\{:\textasciitilde\}}
\end{sourcedisplay}

Also when French is used,
\margintag{punctuation spaces}
\pkg{lwarp} patches \cs{FBcolonspace} and \cs{FBthinspace} to create
fixed-width \HTML\ spaces around punctutation:
\begin{sourcedisplay}
\cs{renewcommand*}\{\cs{FBcolonspace}\}\{\~{}\} \\
\cs{renewcommand*}\{\cs{FBthinspace}\}\{\cs{,}\}
\end{sourcedisplay}
If the user's document also changes these parameters,
\watchout[customized spacing]
the user's changes
should be placed inside a \env{warpprint} environment so that the user's
changes do not affect the \HTML\ output.
}

\newcommand{\limitsnewclude}{%
\pkg{newclude} modifies \cs{label} in a non-adaptive way, so
\pkg{newclude} must be loaded before \pkg{lwarp} is loaded.

\item \texttt{\cs{usepackage}\{newtxmath\}}
\item \dots
\end{enumerate}
}

\newcommand{\limitsglossaries}{%
\texttt{xindy} is required for \pkg{glossaries}.

The default \texttt{style=item} option for \pkg{glossaries} conflicts
with \pkg{lwarp}, so the style is forced to \texttt{index} instead.

The page number list in the printed form would become \cs{nameref}s in \HTML,
which could become a very long string if many items are referenced.
For now, the number list is simply turned off.

\texttt{lwarpmk} has the commands \texttt{printglossary} and
\texttt{htmlglossary} to process the glossaries created by
\pkg{glossaries} using \texttt{xindy}.

The package \pkg{lwarp} takes an option
\DescribeOption{IndexLanguage}
\texttt{IndexLanguage=english} to set the language used by \texttt{xindy}.
This is passed to \texttt{xindy} using its \texttt{-L} option, and is
used for both index and glossary generation.
}


\newcommand{\osportabilityusage}{%
\pkg{lwarp} tries to detect which operating system is being used.
\DescribeProgram{Unix}\DescribeProgram{Mac OS}\DescribeProgram{Linux}
\textsc{Unix}~/ \textsc{Mac~OS}~/ \textsc{Linux} is the default
(collectively referred to as ``\textsc{Unix}'' in the configuration files),
and \textsc{MS-Windows} is supported as well.

If \textsc{Windows} is not correctly detected,
\DescribeProgram{MS-Windows} \DescribeProgram{Windows}
use the \pkg{lwarp} option \texttt{OSWindows}.
\DescribeOption{OSWindows}

When detected or specified, the operating-system path separator used by \pkg{lwarp}
is modified, the boolean \texttt{usingOSWindows} is set true.
This boolean may be tested by the user for later use.

% \begin{abstract}
% \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 \SVG\ files or MathJax.
%
% Documents may be produced by pdf\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 \HTML\ versions of each document may coexist, each with its own
% set of auxiliary files.  Support files are self-generated on request.
% Assistance is provided for import into \EPUB\ conversion software and word processors.
%
% A modular package-loading system uses the \pkg{lwarp} version of a package for
% \HTML\ when available.
% More than a hundred \LaTeX\ packages are supported with these high-level source
% compatibility replacements, and many others work as-is.
%
% A tutorial is provided to quickly introduce the user to the major components
% of the package.

% \section{Updates}
% \label{sec:updates}
%
% The following is intended for those updating existing projects which use
% \pkg{lwarp}, highlighting any special changes which must be made due
% to improvements or modifications in \pkg{lwarp} itself.
%
% For a detailed list of changes, see the Change History on page \pageref{sec:changehistory}.
%
% \begin{description}
% \item[v0.36:] \
%	\begin{itemize}
%	\item Recorganized the documentation section regarding special cases and limitations.
%		(\Cref{sec:limitations})
%   \item Improved source formatting.
%	\item \cs{fbox} and related now use \cs{fboxsep} and \cs{fboxrule}.
%       \margintag{boxes and frames}
%	\item \cs{makebox} and \cs{framebox} now use width and position.
%	\item \cs{fcolorbox} and related now work inside a \env{lateximage}.
%   \item \pkg{babel-french}: Improvements for French variants, load order,
%       \margintag{babel-french}
%       footnotes, ellipses.
%   \item Improved footnote numbering.
%       \margintag{footnotes}
%       \env{lateximage} footnotes now appear as regular footnotes to match
%       the numbering of the print version.
%       Also fixed a regression with MathJax.
%   \item Improved \pkg{siunitx} units.
%       \margintag{siunitx}
%   \item Fix for filenames while using MathJax.
%   \item Fix for \cs{rule} when \pkg{xcolor} is not loaded.
%	\item Added \pkg{transparent}, \pkg{upref}.
%	\end{itemize}
% \item[v0.35:] Fix: \cs{textbf} and related.
% \item[v0.34:] \
%	\begin{itemize}
%	\item \env{BlockClass}'s optional argument has been moved
%		\watchout[Optional arguments]
%		in front of the mandatory argument:
%		\begin{sourcedisplay}
%		|BlockClass[style]{class}| \quad \textrm{(NEW)}
%		\end{sourcedisplay}
%		instead of:
%		\begin{sourcedisplay}
%		|BlockClass{class}[style]| \quad \textrm{(OLD)}
%		\end{sourcedisplay}
%		This change makes it more consistent with \LaTeX\ standards,
%		and avoids problems with space between arguments.
%	\item Likewise, \cs{InlineClass}'s optional argument now
%		\watchout[Optional arguments]
%		comes before the mandatory arguments:
%		\begin{sourcedisplay}
%		|\InlineClass[style]{class}{text}|
%		\end{sourcedisplay}
%	\item Improved compatibility between spans, minipages, lists,
%		\margintag{spans with minipages}
%		frames, and math.
%		Handles minipages and lists inside an \HTML\ span,
%		such as an \cs{fbox} containing a minipage,
%		although with minimal \HTML\ fomatting.
%		See \cref{sec:minipages}.
%		\cs{fboxBlock} is added to frame minipages, tables,
%		\margintag{framing minipages}
%		and lists with full \HTML\ formatting
%		but no longer inline, and behaves as \cs{fbox} for print output.
%		The \env{fminipage} environment is added for framed minipages,
%		as an environment with full \HTML\ formatting,
%		and draws a framed minipage in print output.
%		See \cref{sec:framedminipages}.
%		\cs{fbox} and minipages now often work in \SVG\ math and \env{lateximage}s.
%		MathJax supports \cs{fbox}, but not \cs{fboxBlock} nor \env{fminipage}.
%	\item Improved compatibility between \env{lateximage} and
%		\margintag{lateximage, \SVG\ math, tabular}
%		\env{minipage}, \cs{parbox}, \cs{makebox}, \cs{fbox}, \cs{framebox},
%		\cs{raisebox}, \cs{scalebox}, \cs{reflectbox}, \env{tabular}, \pkg{booktabs}.
%	\item Improved font control for \env{lateximage}es and \SVG\ math.
%	\item Added the \env{eqnarray} environments.\margintag{eqnarray}
%	\item \pkg{fancyvrb} is no longer required (preloaded),
%		\margintag{verbatim packages}
%		but is still supported.
%	\item Added \pkg{verbatim} and \pkg{moreverb}.
%	\item Added \pkg{fancybox}, \pkg{boxedminipage2e} and \pkg{shadow}.
%		\margintag{framing packages}
%	\item \pkg{enumitem} is no longer required, but is still supported.
%		\margintag{list packages}
%	\item Added \pkg{enumerate} and \pkg{paralist}.
%	\item \pkg{titleps} is no longer required, but is still supported.
%	\item Added \pkg{crop}.
%	\item Added \pkg{rotfloat}, \pkg{marginfit},
%		and several minor packages; see the change log.
%	\item Adds fixed-width \HTML\ spaces around punctuation
%		\margintag{babel-french}
%		when using \pkg{babel-french}.
%       \LuaTeX\ does not yet use the extra punctuation spacing.
%	\end{itemize}
% \needspace{2\baselineskip}
% \item[v0.33:] \
%	\begin{itemize}
%	\item Tabular |@| and |!| columns now have their own \HTML\ columns.
%	\item |&| catcode changes are localized, perhaps causing errors
%		about the tab alignment character |&|,
%		so any definitions of macros or environments
%		which themselves contain \env{tabular} and |&| must be enclosed within \cs{StartDefiningTabulars}
%		and \cs{EndDefiningTabulars}.  See \cref{sec:localizingampersand}.
%		This change is not required for the routine use of tables,
%		but only when a table is defined inside another macro or environment,
%		and while also using the |&| character inside the definition.
%		This may include the use inside conditional expressions.
%	\item   Several math environments were incorrectly placed inline.
%		Also, for \pkg{amsmath} with \SVG\ math, the |fleqn| option has been removed,
%		resulting in improved spacing for aligned equations.
%	\item Bug fixes; see the changelog.
%	\end{itemize}
% \item[v0.32:] Bug fixes; no source changes needed:
%	\begin{itemize}
%	\item |lwarpmk| has been adjusted to work with the latest |luatex|.
%	\item Spaces in the \cs{usepackage} and \cs{RequirePackage} package lists are now accepted and ignored.
%	\item Fix for the \pkg{glossaries} package and \cs{glo@name}.
%	\end{itemize}
% \item[v0.31:] Bug fix; no source changes needed:
%	\begin{itemize}
%	\item Improved compatibility with \pkg{keyfloat},
%		including the new \env{keywrap} environment.
%	\end{itemize}
%	\needspace{2\baselineskip}
% \item[v0.30:] \
%	\begin{itemize}
%	\item \pkg{lwarp-newproject} has been removed, and its functions
%		\watchout[\pkg{lwarp-newproject}]
%		have been combined with \pkg{lwarp}.
%
%		To modify existing documents, remove from the document source:
%		\begin{sourcedisplay}
%		\cs{usepackage}\{lwarp-newproject\}
%		\end{sourcedisplay}
%
%		The \pkg{lwarp} package now produces the configuration files during
%		print output, and also accepts the option |lwarpmk| if desired.
%
%	\item A number of macros
%		\watchout[HTML setup changes.]
%		related to \HTML\ settings have been converted to options, and
%		other macros and options have been renamed to create a consistent syntax:
%		\begin{center}
%		\begin{tabular}{ll}
%		\toprule
%		Old Macro & New Package Option \\ \midrule
%		\cs{HomeHTMLFileName} & |HomeHTMLFilename| \\
%		\cs{HTMLFileName} & |HTMLFilename| \\
%		\cs{useLatexmk} & |latexmk| \\
%		\cs{warpOSwindows} & |OSWindows| \\[2.5ex] \toprule
%		Old Package Option & New Package Option \\ \midrule
%		|lwarpmklang| & |IndexLanguage| \\
%		(new) & |xdyFilename| \\[2.5ex] \toprule
%		Old Macro & New Macro \\ \midrule
%		\cs{MetaLanguage} & \cs{HTMLLanguage} \\
%		\cs{HTMLauthor} & \cs{HTMLAuthor} \\
%		\cs{NewHTMLdescription} & \cs{HTMLDescription} \\
%		\cs{SetFirstPageTop} & \cs{HTMLFirstPageTop} \\
%		\cs{SetPageTop} & \cs{HTMLPageTop} \\
%		\cs{SetPageBottom} & \cs{HTMLPageBottom} \\
%		\cs{NewCSS} & \cs{CSSFilename} \\
%		\bottomrule
%		\end{tabular}
%		\end{center}
%
%	\needspace{2\baselineskip}
%	\item Per the above changes, in existing documents,
%		modify the package load of \pkg{lwarp}, such as:
%		\begin{Verbatim}[tabsize=4,gobble=2]
%		\usepackage[
%			HomeHTMLFilename=index,
%			HTMLFilename={},
%			IndexLanguage=english
%		]{lwarp}
%		\end{Verbatim}
%
%	\item The file |lwarp_html.xdy| has been renamed |lwarp.xdy|.
%		To update each document's project:
%		\begin{enumerate}
%		\item Make the changes shown above.
%		\item Recompile the document in print mode.
%			This updates the project's configuration files, and also generates the
%			new file |lwarp.xdy|.
%		\item The old file |lwarp_html.xdy| may be deleted.
%		\end{enumerate}
%
%	\item The new \pkg{lwarp} package option |xdyFilename| may be used to tell
%	|lwarpmk| to use a custom |.xdy| file instead of |lwarp.xdy|.
%	See \cref{sec:modifyxindy}.
%
%	\item Improvements in index processing:
%		\begin{itemize}
%		\item |xindy|'s language is now used for index processing
%			as well as glossary.
%		\item Print mode without |latexmk| now uses |xindy| instead of |makeindex|.
%		\item |texindy|/|xindy| usage depends on |pdflatex| vs |xelatex|, |lualatex|.
%		\item For |pdflatex| and |texindy|, the |-C utf8| option is used.  This is
%			supported in modern distributions, but a customized |lwarpmk.lua| may
%			need to be created for use with older distributions.
%		\end{itemize}
%
%	\end{itemize}
%
% \needspace{2\baselineskip}
%
% \item[v0.29:] \
%	\begin{itemize}
%	\item Add: |lwarpmklang| option for \pkg{lwarp-newproject} and \pkg{lwarp}.
%		Sets the language to use while processing the glossary.
%		(As of v0.30, this has been changed to the |IndexLanguage| option.)
%	\item Fix: \cs{includegraphics} when no optional arguments.
%	\end{itemize}
% \item[v0.28:] \
%	\begin{itemize}
%	\item \cs{HTMLAuthor} \marg{name} assigns \HTML\ meta author if non-empty.
%		Defaults to \cs{theauthor}.
%	\item Booean |HTMLDebugComments| controls whether \HTML\ comments are
%		added for closing \element{div}s, opening and closing sections, etc.
%	\item Boolean |FormatEPUB| changes \HTML\ output for easy \EPUB\ conversion
%		via an external program.
%		Removes per-file headers, footers, and nav.  Adds footnotes per chapter/section.
%	\item Boolean |FormatWordProcessor| changes \HTML\ output for easier conversion
%		by a word processor.  Removes headers and nav, prints footnotes per section,
%		and also forces single-file output and turns off \HTML\ debug comments.
%	\item Boolean |HTMLMarkFloats| adds text marks around floats only if
%		|FormatWordProcessor|.  These make it easier to identify float boundaries,
%		which are to be manually converted to word-processor frames.
%	\item Updated for the new MathJax \acro{CDN} repository.
%	\item Adds \pkg{tabulary}.
%	\item Supports the options syntax for \pkg{graphics}.
%	\item Improved index references, now pointing exactly to their target.
%	\item Adds \pkg{glossaries}.
%		|lwarpmk| is modified to add |printglosssary| and |htmlglossary| actions.

% ^^A 	\item A new tutorial is included in the documentation, and
% ^^A 		many obsolete sections have been removed.
% ^^A 	\item \cs{NewHTMLdescription} sets the \HTML\ meta description tag for each file.

% \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 \HTML\
% interpretation.  No attempt has been made to force \LaTeX{} to provide for every
% \HTML-related possibility, and \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 \HTML\ conversion.
%
% Several ``modern'' features of \HTMLfive, \CSSthree, and \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 \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 \HTML\ output, \SVG\ files are used in placed of \PDF.
% Other formats such as \JPG\ are used as-is.
%
% \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 \MathML\ (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 \SVG{}s at high resolution.} browser
% support).
%
% Furthermore, \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
% \MathML\ 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 \SVG\ images.
% Subject to browser support and Internet access,
% MathJax allows an \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 \HTML\
% version of the document.  A few external utility programs are used to finish
% the conversion from a \LaTeX{}-generated \PDF\ file which happens to have \HTMLfive\ tags,
% to a number of \HTMLfive\ plain-text files and accompanying images.
%
% \pkg{lwarp} automatically generates the extra files necessary for
% the \HTML\ conversion, such as \CSS\ and |.xdy| files, and configuration files
% for the utility |lwarpmk|.
% Also included is a parallel version of the user's source document,
% |<sourcename>-html.tex|, which selects \HTML\ output and then inputs the user's own source.
% This process allows both the printed and \HTML\ versions to co-exist side-by-side,
% each with their own auxiliary files.
%
% When requesting packages during \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 \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}.)
%
% Assistance is provide for modifying the \HTML\ output to suite the creation
% of \EPUB\ documents, and for modifying the \HTML\ output to ease import into
% a word processor.
%
%
% \subsection{Supported packages and features}
%
% \changes{v0.15}{2016/04/05}{Docs: Moved the supported functions table to the introduction.}
%
% Supported classes include \pkg{book}, \pkg{report}, and \pkg{article}.
% \pkg{memoir} is planned, but in the meantime many of the packages
% used by \pkg{memoir} are already supported.
%
%
% \Cref{tab:supported} lists some of the various \LaTeX{} features 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.

%
% \section{Alternatives}
% 
% Summarized below are several other ways to convert a \LaTeX{} or other document to \HTML.
% Where an existing \LaTeX{} document is to be converted to \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 \HTML\ and \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 \HTML\ conversion by way of numerous configuration
% files.
% In some cases, \pkg{lwarp} provides a better \HTML\ conversion, and it
% supports a different set of packages.
% TeX4ht produces several other forms of output beyond \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 \HTML.
% Search for each on \CTAN\ (\url{http:\\ctan.org}).

% 
% \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 \HTML.

%
% A markup system which also reads and writes \LaTeX{} and \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 \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 to
%	install the package |lwarp|.
%	Also update the package |miktex-misc|, which will install the
%	|lwarpmk| executable.
% \changes{v0.26}{2017/03/23}{Docs: Improved MiK\TeX\ install instructions.}
%
% \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[MiK\TeX:] \
%
%			In the ``Settings'' window, ``Roots'' tab, look for a local \TDS\ root.
%		\end{description}
%		This should be something like:
%		\begin{sourcedisplay}
%		|/usr/local/texlive/texmf-local/|
%		\end{sourcedisplay}
%	\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:
%		\begin{sourcedisplay}
%		|<texlocal>/tex/latex/local/lwarp|
%		\end{sourcedisplay}
%	\item Copy the documentation |lwarp.pdf| to a |source| directory in the local tree,
%		such as:
%		\begin{sourcedisplay}
%		|<texlocal>/doc/local/lwarp|
%		\end{sourcedisplay}
%	\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.

%
% \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}.
%
% \item For MiK\TeX, try updating the |miktex-misc| package.  This may install
% the |lwarpmk| executable for you.
% \changes{v0.26}{2017/03/23}{Docs: Improved MiK\TeX\ install instructions.}
%
%	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:
%		\begin{sourcedisplay}
%			|/usr/local/texlive/<year>|
%		\end{sourcedisplay}
%			The binaries are then located in the |bin/<arch>| directory
%			under the root:
%		\begin{sourcedisplay}
%			|/usr/local/texlive/<year>/bin/<architecture>/|
%		\end{sourcedisplay}
%			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:
%		\begin{sourcedisplay}
%			|C:\Program Files\MiKTeX 2.9\miktex\bin\x64|
%		\end{sourcedisplay}
%			In this directory you will find programs
%			such as |pdflatex.exe| and |makeindex.exe|.
%		\item Create a new file named |lwarpmk.bat| containing:
%		\begin{sourcedisplay}
%			{\footnotesize
%			|texlua "C:\Program Files\MiKTeX 2.9\scripts\lwarp\lwarp.texlua" %*|}
%		\end{sourcedisplay}
%			This will call the copy of |lwarpmk.lua|

% \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} package:
%	\begin{sourcedisplay}
%	|\usepackage[lwarpmk]{lwarp}|
%	\end{sourcedisplay}
% \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.

% This section shows an example of how to create an \pkg{lwarp} document.
%
%
% \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|.
%
% \item Inside the |tutorial| directory,
% \DescribeFile{tutorial.tex}
%	create a new file called |tutorial.tex|.
%	This may be done several ways:
%	\begin{description}
%	\item [Copy from the documentation PDF:] \
%
%	A listing is in \cref{fig:tutorial},
%	which may be copied/pasted from the figure directly into your own editor,
%	depending on the quality of the \PDF\ viewer and editor, or:
%
%	\item [Copy from the \pkg{lwarp} documentation directory:] \
%
%	Another copy may be found by entering into a command line:
% \DescribeFile{lwarp_tutorial.txt}
%	\watchout[Note: |.txt| suffix!]
%	\userentry{texdoc -l lwarp\_tutorial.txt}
%
%	This should be in the |doc/latex/lwarp/| directory along
%	with this \PDF\ documentation.
%	Copy |lwarp_tutorial.txt| directly into your |tutorial| directory,
%	renamed as |tutorial.tex|.
%	\end{description}
%
%	\emph{When using Windows, use an editor other than Notepad,
%	\watchout[Bad formatting!]
%	since Notepad does not accept the end-of-line from a Unix text file.}
%
% \item Compile the project: \userentry{pdflatex tutorial.tex}
%				\quad (several times)
%
% (|xelatex| or |lualatex| may be used as well.)
%
% \item View the resulting |tutorial.pdf| with a \PDF\ viewer.
%
% \end{enumerate}
%
%
% A number of new files are created when |tutorial.tex| is compiled, as
% shown in \cref{fig:newprojectfiles}.  These files are created by
% the |lwarp| package.
%
% (Two of the new files are configuration files for the helper program |lwarpmk|.
% Whenever a print version of the document is created,
% the configuration files for |lwarpmk| are updated to
% record the operating system, \LaTeX\ program (|pdflatex|, |xelatex|, or |lualatex|),
% the filenames of the source code and \HTML\ output, and whether
% the additional helper program |latexmk| will be used to compile the document.)

% \begin{description}
%
% \item [|tutorial.pdf|:] The \PDF\ output from \LaTeX.
%	The print version of the document.
%
% \item [|tutorial\_html.tex|:] A small |.tex| file used to create
%	a parallel \HTML\ version of the document, which co-exists with usual
%	the \PDF\ version, and which will have its
%	own auxiliary files.  In this way, both \PDF\ and \HTML\
%	documents may co-exist side-by-side.
%
% \item [Auxiliary files:] The usual \LaTeX\ files |.aux|, |.log|, |.out|, |.toc|, |.lof|, |.idx|.
%	When an \HTML\ version of the document is created, |_html| versions
%	of the auxiliary files will also be generated.
%
% \item [|lwarpmk.conf|:] A configuration file for |lwarpmk|,
%	which is used to automate the compilation of \PDF\ or \HTML\
%	versions of the document.
%
% \item [|tutorial.lwarpmkconf|:] Another configuration file used by |lwarpmk|,
%	which is only useful if you wish to have several projects
%	residing in the same directory.
%
% \item [|.css files|:] |lwarp.css|, |lwarp_formal.css|, |lwarp_sagebrush.css|
%	These files are standard for \pkg{lwarp}, and are not meant to be modified
%	by the user.
%
% \item [|sample\_project.css|:] An example of a user-customized \CSS\ file,
%	which may be used for project-specific changes to the \pkg{lwarp} defaults.
%
% \item [|lwarp.xdy|:] Used by \pkg{lwarp} while creating an index.
%	This file should not be modified by the user.
%	A custom file may be used instead, if necessary.
%
% \item [|lwarp\_mathjax.txt|:] Inserted into the \HTML\ files when
%	|MathJax| is used to display math.
%	This file should not be modified by the user.
%
% \item [|comment.cut|:] A temporary file used by \pkg{lwarp} to
%	conditionally process blocks of text.  This file may be ignored.

%
% \subsection{Compiling the print version with \texttt{lwarpmk}}
%
% The |lwarpmk| utility program is used to compile either the printed or
% the \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.\index{index>processing}\footnote{A \texttt{lwarpmk printglossary} command is also
%	available to process a glossary produced with the \textsf{glossaries} package.
%	See \cref{sec:glossaries}.}
%	\userentry{lwarpmk printindex}
%
% \item Recompile again to include the index.
%	\userentry{lwarpmk print}
%
% \end{enumerate}
%
% Note that the \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 \HTML\ version of the document.
%
% \begin{enumerate}
% \item Compile the \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 to the file |tutorial_html.html|.
%		This file is a plain-text file containing \HTML\ tags and
%		content for the entire document.
%	\item |lwarpmk| manually splits |tutorial_html.html| into
%		individual \HTML\ files according to the \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 \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 been generated.  Math may be
%	displayed as \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 \HTML\ index and recompile:\index{index>processing}\footnote{A \texttt{lwarpmk htmlglossary} command is also
%	available to process a glossary produced with the \textsf{glossaries} package.
%	See \cref{sec:glossaries}.}
%	\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 \SVG\ images with
% \margintag{math as \SVG\ images}
% the \LaTeX\ source included in \attribute{alt} attributes.  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 \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}
%
% \limitssvgimages
%
% \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, uncomment the |mathjax| package option for \pkg{lwarp}:
%	\begin{sourcedisplay}
%	mathjax, \% Use MathJax to display math.
%	\end{sourcedisplay}
%
% \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{\CSSFilename}
% \cs{CSSFilename} may be used to choose which |.css| file is used to display
% each section of the web page.  Use \cs{CSSFilename} before |\begin{document}|
% to assign the style of the home page.
% If different parts of the website should have different styles,
% call \cs{CSSFilename} 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{CSSFilename} is not used.  This
%	style is comparable to a plain \LaTeX\ document.
%	To set this style, you may use |\CSSFilename{lwarp.css}|, or no \cs{CSSFilename} 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{CSSFilename} entry in the tutorial,
% |lwarpmk html| again, and then reload the webpage.
%
% A customized style may also be created.
% \margintag{Custom \CSS}
% For each new project a file
% called |sample_project.css| is generated.  This may be renamed to
% |<project>.css| then used by assigning |\CSSFilename{<project>.css}|.
%
% Note that |sample_project.css| is overwritten whenever \pkg{lwarp}
% 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 \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 \HTML\ output.
% Watch for the correct placement of each!\watchout[Placement!]
%
% Note that if changes are made,
% \watchout[Changes!]
% it is best to first:
% \begin{enumerate}
% \item Clear all the \HTML, \PDF, and auxiliary files: \userentry{lwarpmk clearall}
% \item Recompile the print version in order to recreate
%	the configuration files for |lwarpmk|: \userentry{lwarpmk print}
% \item Finally, recompile the \HTML\ version with the new settings: \userentry{lwarpmk html}
% \end{enumerate}
%
% \begin{description}[style=unboxed]
%
% \item[Options for the \pkg{lwarp} package:] \ \newline
%	Use the following as options for |\usepackage[<options>]{lwarp}|:
%
%	\begin{description}
%
% \ItemDescribeOption{HomeHTMLFilename} Filename of the homepage, without
%	the ``|.html|'' suffix.
%	Defaults to the \cs{BaseJobname}.  A common setting is:
%	\begin{sourcedisplay}
%	|HomeHTMLFilename=index|
%	\end{sourcedisplay}
%	causing the
%	homepage to be the file |index.html|.  Underscores are allowed in
%	\margintag{filename underscores}
%	|HomeHTMLFilename| and |HTMLFilename| options, but may need to be escaped
%	elsewhere, such as when appearing in a list:
%	\index{underscore>filename}\index{file>underscore}
%	\changes{v0.24}{2017/03/13}{Docs: Filename underscore.}
%	\begin{sourcedisplay}
%	     \cs{item} [\cs{href}\{file\textcolor{red}{\textbackslash\_}name.pdf\}\{text\}] \textbackslash
%	\end{sourcedisplay}
%
% \ItemDescribeOption{HTMLFilename} A filename prefix for the rest of the \HTML\ web pages.
%	Useful for numbered web pages with a common prefix.  May be empty.
%
% \ItemDescribeOption{latexmk} Controls whether
%	\pkg{lwarp} uses |latexmk| to
%	compile the document.  This setting is written to |lwarpmk|'s configuration
%	files.  Defaults to false.
%
% \ItemDescribeOption{mathsvg} Selects \SVG\ display for math output.  (The default.)
%
% \ItemDescribeOption{mathjax} Selects MathJax for math output.
%
%	\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\TOC.
%	Defaults to 1, causing the side\TOC\ to show sections but not subsections.
%
%	Each subpage of the website has its own small table of contents
%	\margintag{side\TOC}
%	on the side (the ``side\TOC'').  Its depth is set by |SideTOCDepth|.
%	This side\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\TOC\ at the top of the
%	page and a link back to ``Home'' at the bottom.
%
%	\label{sec:filedepth}
%	It is recommended to set:
%	\begin{sourcedisplay}
%	|SideTOCDepth|\,=\,|FileDepth|
%	\end{sourcedisplay}
%	or
%	\begin{sourcedisplay}
%	|SideTOCDepth|\,=\,|FileDepth|+1
%	\end{sourcedisplay}
%
%	If |SideTOCDepth|\,<\,|FileDepth|, web pages will be inaccessible via the
%	side\TOC.  \watchout
%	\index{file>inaccessible}
%	\index{page>inacessible}
%	\index{missing sections}
%	\index{section>missing}
%
% \ItemDescribeCounter{FileDepth} Sectioning depth of file splits.
%	Defaults to -5, causing the entire \HTML\ website to be one single file.
%	\begin{itemize}
%	\item To place the entire file into one \HTML\ page, use:
%		\begin{sourcedisplay}
%		|\setcounter{FileDepth}{-5}}|
%		\end{sourcedisplay}
%	\item To split the \HTML\ file at \cs{section} depth, use:
%		\begin{sourcedisplay}
%		|\setcounter{FileDepth}{1}}|
%		\end{sourcedisplay}
%	\item To ensure that the \HTML\ pages/files are accessible:
%		\watchout\\
%		Place a \cs{tableofcontents} somewhere before the first section
%		break (therefore in the ``home page''), and set
%		\begin{sourcedisplay}
%		|tocdepth|\,>=\,|FileDepth|
%		\end{sourcedisplay}
%		\index{file>inaccessible}
%		\index{page>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 |HTMLFilename| option is used as a prefix.
%
%	Example \HTML\ filenames:
%	\changes{v0.20}{2016/09/11}{Docs: Examples for generating \HTML\ file names.}

% \subsection{Using \texttt{latexmk}}
%
% |latexmk| is a \LaTeX\ utility used to monitor changes in source files
% and recompile as needed.
%
% \begin{enumerate}
% \item In the tutorial's source code uncomment the |latexmk| option for the
%	\pkg{lwarp} package:
%	\begin{sourcedisplay}
%	latexmk,   \% Use latexmk to compile.
%	\end{sourcedisplay}
%
% \item Recompile the printed version of the document.
%	\userentry{lwarpmk print}
%
%	\begin{sloppy}
%	\pkg{lwarp} updates its own configuration files (|lwarpmk.conf| and \newline
%	|tutorial.lwarpmkconf|) whenever the printed version of the document
%	is compiled.  These configuration files remember that |lwarpmk| should
%	use |latexmk| to compile the document.
%	\end{sloppy}
%
% \item Recompile the document.
%	\userentry{lwarpmk print} \quad and/or
%	\userentry{lwarpmk html}
% \end{enumerate}
%
% Changes are detected by comparing checksums
% rather than modification times, so |lwarpmk again| will not trigger a
% recompile, but |latexmk| has a much better awareness of changes than
% the |lwarpmk| utility does and it is likely to correctly know when to
% recompile.  A recompile may be forced by making a small change to the source.

% \item Use |xelatex| or |lualatex| to recompile the printed version.
%	\userentry{xelatex tutorial.tex} \quad -or-
%	\userentry{lualatex tutorial.tex}
%
%	When the recompile occurs,
%	the configuration files for |lwarpmk| are modified to remember
%	which \TeX\ engine was used.  \XeLaTeX\ or \LuaLaTeX\ will be used for

%
% \item To recompile the document:

% Everything is handled in UTF-8 encoding, and should work as expected.
%
% While using |pdflatex|, the |texindy| program is used with the |-C utf8| option,
% which is newly supported in recent distributions of \LaTeX.  This option correctly
% sorts index entries into headings while using Latin languages, but will not work
% well with others.  \XeLaTeX\ or \LuaLaTeX\ are recommended for non-Latin languages.
%
% For an older distribution of \LaTeX, it may be necessary to generate a local version of

%
% Certain print-related commands should always be placed

% These are unrelated to \HTML\ output, but are hard to isolate automatically.
% For example:

% \begin{itemize}
% \item Paragraph formatting: \cs{parindent} \cs{parskip}
% \item Manual page positions such as the \pkg{textpos} package, which is

% \DescribeFile{lwarp.xdy}
% \pkg{lwarpmk} uses the file |lwarp.xdy| to process the index.
% \index{lwarp.xdy>customizing}
% \index{xindy>customizing}
% This file is over-written by \pkg{lwarp} whenever a print version of
% the document is processed.
%
% To customize index processing:
% \begin{enumerate}
% \item Copy |lwarp.xdy| to a new filename such as |projectname.xdy|
% \item Make changes to |projectname.xdy|.
%	Keep the line which says
%	\begin{Verbatim}[gobble=2,tabsize=4]
%		(markup-locref :open "\hyperindexref{" :close "}")
%	\end{Verbatim}
%	This line creates the hyperlinks for the \HTML\ index.  During print output
%	\cs{hyperindexref} becomes a null function.
% \item In the document source use the |xdyFilename| option for \pkg{lwarp}:
% \DescribeOption{xdyFilename}
%	\begin{Verbatim}[gobble=2,tabsize=4]
%		\usepackage[
%			... other options ...
%			xdyFilename=projectname.xdy,
%		]{lwarp}
%	\end{Verbatim}
% \item Recompile the print version, which causes
%	\pkg{lwarp} to rewrite the |lwarpmk.conf| configuration file.
%	This tells |lwarpmk| to use the custom |projectname.xdy| file instead of |lwarp.xdy|.

%
% \subsubsection{Framed minipages and other environments}
%	\label{sec:framedminipages}
%
%	\cs{fbox} can only be used around inline \element{span} items during
%	\HTML\ output, but \HTML\ cannot place a block element such as a \element{div} for a minipage
%	or a list inside of a \element{span}.  Several options are provided for framing an object,
%	depending on which kind of object and which packages are loaded:
%
%	For a framed object, options include:
%	\DescribeMacro{\fbox}
%	\DescribeMacro{\fboxBlock}
%	\DescribeEnv{fminipage}
%	\index{fbox>around a minipage}
%	\index{minipage>framed}
%	\index{framed objects}
%	\begin{description}[style=unboxed]
%	\item [To remove the frame in HTML output:] Place the \cs{fbox} command and
%		its closing brace inside \env{warpprint} environments.
%		This will nullify the frame for \HTML\ output.
%	\item [To frame the contents inline with some formatting losses in HTML:]
%		This is the default action of \cs{fbox} when enclosing a minipage.
%		\margintag{For inline text:}
%		During \HTML\ output, \cs{fbox} nullifies the \HTML\ tags
%		for \env{minipage}, \cs{parbox},
%		and lists.  The contents are included as inline text inside the
%		\cs{fbox}'s \element{span} of class |framebox|.
%		For lists, line breaks are converted to \HTML\ breaks.
%		The result is a plain-text inline version of the contents, framed inline
%		with the surrounding text, but lacking any extra \HTML\ markup.
%	\item [To frame the contents on their own line with improved formatting in HTML:] A new
%		command \cs{fboxBlock} is included,
%		\margintag{For inline \env{minipage} and lists:}
%		intended to be a direct replacement
%		for \cs{fbox} for cases where the \cs{fbox} surrounds a minipage, table, or list.
%		For print output, this behaves as \cs{fbox}.
%		For \HTML\ output, the contents are placed
%		inside an \HTML\ \element{div} with the class |framed|, resulting in the contents
%		being placed on their own line with a frame surrounding them.
%		The contents preserve their \HTML\ formatting, so lists and minipages look nicer,
%		and valid \HTML\ is created for a \env{tabular}.
%		While an \cs{fbox} containing a \env{tabular} is valid \LaTeX\ code, the result
%		in \HTML\ is problematic since a table is a \element{div} not a \element{span},
%		so use \cs{fboxBlock} around a \env{tabular}, or else place the \env{tabular}
%		inside a \env{minipage}, or use \env{fminipage}, described next.
%		Also see below regarding the ``Misplaced alignment tab character \&'' error.
%	\item [To create a framed minipage in both print and HTML:] A new environment \env{fminipage}
%		\margintag{For display \env{tabular}, minipages, and lists:}
%		is included.  For print output, this is identical to \env{minipage}, except that
%		it is also framed.
%		For \HTML\ output, this forms a \element{div} of class |framed|, the contents
%		preserve their \HTML\ formatting, and valid \HTML\ is created for a \env{tabular}.
%		Also see below regarding the ``Misplaced alignment tab character \&'' error.
%	\item [To create colored frames and boxes:] See \cref{sec:xcolor} for \pkg{xcolor}'s
%		\margintag{colored boxes and frames:}
%		\cs{colorbox} and \cs{fcolorbox},
%		and \pkg{lwarp}'s additional \cs{colorboxBlock} and \cs{fcolorboxBlock}.
%	\item [To frame tables or verbatim environments:] Place the contents
%		inside a \env{fminipage}, or perhaps a \cs{fboxBlock} for a \env{tabular}.
%		Also, if using \cs{fboxblock} with \env{tabular},
%		\watchout[Misplaced alignment tab character \&]
%		you will have to use \cs{StartDefiningTabulars}
%		before the start of the macro which uses \cs{fboxBlock} and the \env{tabular},
%		and \cs{EndDefiningTabulars} afterwards.
%		Also see the \pkg{lwarp} documentation for the \pkg{fancybox} package.
%	\item [To frame equations:] See \cref{sec:fancybox} for the \pkg{fancybox} package.
%	\item [For fancy framed minipages:] See packages \pkg{boxedminipage},
%		\pkg{shadow}, \pkg{fancybox}, \pkg{framed}, \pkg{mdframed}.
%	\item [Custom environments:] Use a custom environment to create a sidebar,
%		containing a \env{BlockClass} environment
%		with custom \CSS\ formatting,
%		 and |\warpprintonly{\hrule}| command:
% \begin{Verbatim}[gobble=2,frame=lines]
% \begin{BlockClass}{frameminipage}% ignored in print output
%   % use CSS to format div class ``framedminipage''
% \warpprintonly{\hrule} % only appears in print output

% \label{sec:epub}

% \pkg{lwarp} does not produce \EPUB\ documents,
% but it may be told to modify its \HTML\ output
% to greatly assist in the conversion.
% An external program may then be used to finish the conversion
% to \EPUB.
%
% To assign the author's name for regular \pkg{lwarp} \HTML\
% \margintag{\element{meta} author}
% files, and also for the \EPUB,
% use \cs{HTMLAuthor} \marg{name}.  This assigns the name to the
% \element{meta} author element.  It may be set empty, and it defaults to
% \cs{theauthor}.
%
% A special boolean is provided to simplify the process of
% converting \pkg{lwarp} \HTML\ output to \EPUB:
%
% \DescribeBoolean{FormatEPUB}
% \begin{docsidebar}
%	\raggedright
%	Default false.
%	|FormatEPUB| changes \HTML\ output for easy \EPUB\ conversion
%	via an external program. Removes per-file headers, footers, and nav.
%	Adds footnotes per chapter/section.
% \end{docsidebar}
%	\index{EPUB>HTML conversion settings}
%	\index{HTML>conversion settings>EPUB}
%
% To help convert \pkg{lwarp} \HTML\ output to \EPUB, add
%	\begin{sourcedisplay}
%	|\booltrue{FormatEPUB}|
%	\end{sourcedisplay}
% to the project's source preamble after |\usepackage{lwarp}|.
% The \EPUB\ version of the document cannot co-exist with the
% regular \HTML\ version, so \userentry{lwarpmk cleanall} then
% \userentry{lwarpmk html}
% to recompile with the |FormatEPUB| boolean turned on.
% Several changes are then made to the \HTML\ output:
%	\begin{itemize}
%	\item Headers, footers, and navigation are removed at file splits.
%	\item Any accumulated footnotes are printed at the bottom of each file split.
%	\end{itemize}
%
% The resulting files will be ready to be loaded into an \EPUB\ conversion
% program, such as the open-source program Calibre (\url{https://calibre-ebook.com/}).
% \index{Calibre}\index{EPUB>conversion software}\margintag{Calibre}
%
% The \EPUB\ conversion program must know what order the files are included.
% For \pkg{lwarp} projects, set the \EPUB\ conversion software to
% \watchout[search order]
% do a breadth-first search of the files.
% For Calibre, this option is found in
% \begin{UIdisplay}
%	\textsf{Preferences $\to$ Plugins $\to$ File type plugins $\to$ HTML to Zip}
% \end{UIdisplay}
% Check the box \textsf{Add linked files in breadth first order.}
% 
% The \EPUB-conversion program must also know where the section breaks are located.
% \watchout[section breaks]
% For a list of \pkg{lwarp}'s section headings,
% see \cref{tab:depthsheadings}.
% For example, an |article|
% class document would break at \cs{section}, which is mapped to \HTML\
% heading level \element{h4}, whereas a |book| class document would break at \cs{chapter},
% which is \HTML\ heading level \element{h3}.
% For Calibre, this option is found in
% \begin{UIdisplay}
%	\textsf{Preferences $\to$ Conversion (Common Options) $\to$
%	Structure Detection $\to$ Detect chapters at (XPath expression)}
% \end{UIdisplay}
% Select the ``magic wand'' to the right of this entry box, and set
% the first entry
% \begin{UIdisplay}
%	Math HTML tags with tag name:
% \end{UIdisplay}
% to \element{h4}.  (Or \element{h3} for document classes with \cs{chapter}s.)
% The \textsf{Detect chapters at} field should then show
% \begin{UIdisplay}
%	//h:h4 \qquad \textrm{---\,or\,---} \qquad //h:h3
% \end{UIdisplay}
%
% This option is also available on the main tool bar at the \textsf{Convert books}
% button.
%
% Once these settings have been made, the \pkg{lwarp}-generated \HTML\ files
% may be loaded by Calibre, and then converted to an \EPUB.
%
% \begin{docsidebar}[MathJax support]
% MathJax may be used in \EPUB\ documents.
% Some e-readers include MathJax, but any given reader
% may or may not have a recent version, and may or may not include
% extensions such as support for \pkg{siunitx}.
%
% \pkg{lwarp} adds some modifications to \MathML\ to support equations numbered
% by chapter.  These modifications may not be compatible with the e-reader's
% version of MathJax, so \pkg{lwarp} requests that a known version be loaded
% instead.  In some cases chapter numbering of equations still doesn't work.
%
% Until math support in \EPUB\ documents is improved, it is recommended to use
% \SVG\ images instead of MathJax, especially for equations numbered by chapter,
% or where \pkg{siunitx} support is important.

% \section{Word-processor conversion}
%
% \pkg{lwarp} may be told to modify its \HTML\ output to make it
% easier to import the \HTML\ document into a word processor.
% At the time of this writing, it seems that LibreOffice works best at
% preserving table layout, but it still has some limitations, such as
% an inability to automatically assign figure and table
% frames and captions according to user-selected \HTML\ classes.
% \pkg{lwarp} provides some assistance in locating these frame boundaries,
% as shown below.
%
%
% A special boolean is provided to simplify the process of

%
% \DescribeBoolean{FormatWordProcessor}

% Several changes are then made to the \HTML\ output:
%	\begin{itemize}
%	\item Headers, footers, and navigation are removed at file splits.
%	\item Any accumulated footnotes are printed at the bottom of each file split.
%		These will have to be manually moved to their proper place in
%		the document.  \pkg{lwarp} does not know where the page breaks
%		will be in the word processor's document, so the footnotes are
%		simply moved to the end of each sectional break.
%	\item Forces single-file output.
%	\item Turns off \HTML\ debugging comments.
%		These are comments appearing inside the \HTML\ code,
%		marking the opening/closing of sections and \element{div}s,
%		but they are no longer useful when the document has been
%		imported into a word processor.
%	\end{itemize}
%
% An additional boolean may be set to help mark float boundaries:
%
% \DescribeBoolean{HTMLMarkFloats}
%	\begin{docsidebar}
%	\raggedright
%	Default true.
%	Adds |=== table begin| or |=== figure begin|, and |=== end|

%
% \section{Modifying \protect\pkg{lwarp}}
% \pagestyle{pageheadfoot}
%
% Purely text-based packages probably will work as-is when generating
% \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 \HTML\ block or inline \CSS\ class,
% see \cref{sec:highlevelclasses}.
%
% \subsection{Creating an \protect\pkg{lwarp} version of a package}
%
% When creating \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 users to create their own
% versions of packages for \pkg{lwarp} to use for \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}.  (Remember |mktexlsr| or |texhash|.)
%
% An |lwarp-<packagename>.sty| package is only used during \HTML\
% generation.  Its purpose is to pretend to be the original package,
% while modify anything necessary to create a successful \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.
%
% 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.
% In many of these packages, most of the new definitions have a ``local'' prefix
% according to the package name, and |@| characters inside the name,
% which hides these names from the user.  In most cases these macros
% will not need to be emulated for \HTML\ output.  Only the ``user-facing''
% macros need to be nullified or emulated.
%
% Each |lwarp-| package should first call either \cs{LWR@ProvidesPackageDrop}
% or \cs{LWR@ProvidesPackagePass}.  If |Drop|ped, the original print-version
% package is ignored, and only the |lwarp-| version is used.
% Use this where the original print version is useless for \HTML.
% If |Pass|ed, the original package is loaded first, with the user-supplied options,
% then the |lwarp-| version continues loading as well.
% See \cref{sec:ntheorem} (\nameref{sec:ntheorem})
% for an example of selectively disabling user options for a package.
% Use this when \HTML\
% output only requires some modifications of the original package.
% For a case where the original package is usable without changes, there is no
% need to create a |lwarp-| version.
%
%
% \subsection{Testing \protect\pkg{lwarp}}
%
% \changes{v0.25}{2017/03/22}{Docs: Testing \protect\pkg{lwarp}.}
%
% When changes have been made, test the print output before testing the
% \HTML.  The print output compiles faster, and any errors in the printed
% version will be easier to figure out than the \HTML\ version.
%
% Remember that the configuration files are only rewritten when compiling the
% printed version of the document.
%
% Sometimes it is worth checking the |<project>_html.pdf| file, which is the
% \PDF\ containing \HTML\ tags.  Also, |<project>_html.html| has
% the text conversion of these tags, before the file is split into individual
% \HTML\ files.
%
% It is also worth checking the browser's tools for verifying the correctness
% of \HTML\ and \CSS\ code.

% compile documents:
% \begin{enumerate}
% \item Add the |lwarpmk| option to the \pkg{lwarp} package.
% \item Recompile the printed version of the document.
%	The |lwarpmk| option causes \pkg{lwarp} to create a local copy of |lwarpmk.lua|

% \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 \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 \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 \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 \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 \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} & \HTML\ headings \\
% \midrule
% title of the entire website & & \element{h1} \\
% none			& -5	& new for this package \\
% book			& -2	& \textbf{not yet used} \\
% part			& -1	& \element{h2} \\
% chapter		& 0 	& \element{h3} \\
% section		& 1		& \element{h4} \\
% subsection	& 2		& \element{h5} \\
% subsubsection	& 3		& \element{h6} \\
% paragraph		& 4		& \element{span class = "paragraph"} \\
% subparagraph	& 5		& \element{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 |book|
% level, which may push the \HTML\ headings down a step, and also cause
% |subsubsection| to become a \element{div} due to a limit of six \HTML\ headings.
%
% It is possible to use \HTMLfive{} \element{section} and \element{h1} for all levels,
% but this may not be well-recognized by older browsers.
%
% Fixed levels for parts and chapters allow the \CSS\ to remain fixed as well.

% \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@depthfinished}{-4}
\newcommand*{\LWR@depthpart}{-1}
\newcommand*{\LWR@depthchapter}{0}
\newcommand*{\LWR@depthsection}{1}
\newcommand*{\LWR@depthsubsection}{2}
\newcommand*{\LWR@depthsubsubsection}{3}
\newcommand*{\LWR@depthparagraph}{4}
\newcommand*{\LWR@depthsubparagraph}{5}
%    \end{macrocode}
% used by |\itemize|, |\enumerate|, |\description|:
%    \begin{macrocode}
\newcommand*{\LWR@depthlist}{6}
%    \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}
\newcommand*{\LWR@closeone}{}% top of the stack

% \section{Sectioning}

%
% 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 \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,
% \watchout
% it may be that |pdflatex| is actually producing a symbol over or under a
% character, resulting in |pdftotext| picking up the accent symbol separately.
%
% \XeLaTeX{} and \LuaLaTeX{} directly support accented section and file names.
% \index{accents}\index{Unicode>file \& section names}\index{UTF-8>file \& section names}

% \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 \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 \HTML\ page, such as:
%
% \DescribeMacro{\HTMLPageBottom} \marg{text}
% \begin{Verbatim}[gobble=2,frame=lines,obeytabs,tabsize=4]
% \HTMLPageBottom{
% \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

% The environments |itemize|, |enumerate|, and |description| are patched
% when \pkg{lwarp} is started.  These patches support the standard
% \LaTeX\ environments, as well as those of \pkg{enumerate}, \pkg{enumitem},
% and \pkg{paralist}, and at least the French version of \pkg{babel}.
% Additional patches are done on a package-specific basis.
%
% The \LaTeX\ source for |itemize| and |enumerate| are found in |source2e|, but
% the source for |description| is found in |article.cls|, etc.
%
% To have an empty
% item,\margintag{empty item}\index{item>empty}\index{list item, empty} use
% |\mbox{}| or a trailing backslash.
% This forces a new line in print output, matching the new line which
% will appear in \HTML\ output.

% \item [l, r, c:] Converted to table cells without paragraph tags. \\
% Uses \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 \CSS\ |vertical-align:bottom| is used to
% have the \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 \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 \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, \CSS\ |vertical-align:middle|.
% \item [b:] With paragraph tags, \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.
% \item [D:] Converted to 'c'.  From the \pkg{dcolumn} package.
% \item [@, !, \textgreater{}, \textless{}:] One each, in that order.

% \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''.

%	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,

% \subsubsection{Caption and LOF linking and tracking}

% When a new \HTML\ file is marked in the \LaTeX\ \PDF\ file,
% the \LaTeX\ page number at that point is stored in |LWR@latestautopage|,
% (and the associated filename is remembered by the special \LaTeX\ labels).
% This page number is used to generate an |autofloat| \HTML\ \element{id}
% in the \HTML\ output at the start of the new \HTML\ file.
% Meanwhile, there is a float counter used to generate an \HTML\ |autofloat|
% \element{id} at the start of the float itself in the \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 \HTML\ links in the List of Figures, etc.
%
% \DescribeCounter{LWR@nextautofloat} Tracks autofloat for floats.
% \DescribeCounter{LWR@nextautopage} Tracks autopage for floats.
%
% These are updated per float as the |.lof| file is read.

% \section{Lateximages}

% A |\lateximage| is typeset on its own \PDF\ page inside an \HTML\ comment
% which starts on the preceeding page and ends on following page, and instructions are written to
% |lateximage.txt| for |lwarpmk| to extract the |\lateximage| from the page of the \PDF\ file
% then generate an accompanying |.svg| file image file.  Meanwhile, instructions to
% show this image are placed into the \HTML\ file after the comment.
%
% An \HTML\ span is created to hold both the \HTML\ comment,
% which will have the |pdftotext| conversion,
% and also the link to the final |.svg| image.
%
% A \LaTeX\ label is used to remember which \PDF\ page has the image.
% A label is used because footnotes, endnotes, and pagenotes may cause the image to appear
% at a later time.  The label is declared along with the image, and so it correctly remembers
% where the image finally ended up.

% \section{Cleveref}
% \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 \HTML\ conversion requires \pkg{cleveref}.
% The user's document may not require \pkg{cleveref}, thus the user
% may never explicitly load it, so during \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 \HTML\ does not allow
% a \element{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 \HTML\ paragraph closing tag is

%
% \subsection{Xcolor definitions: location and timing}
%
% The \pkg{lwarp} core and its \pkg{lwarp-xcolor} package are tightly integrated
% to allow comparable results for print, \HTML\,
% and print inside an \HTML\ \env{lateximage}.
% This requires a number of definitions and redefintions depending on whether
% each of \pkg{xcolor} and \env{lateximage} is being used, and whether print
% or \HTML\ is being generated.
% Some of these actions are one-time when \pkg{xcolor} is loaded, and others
% are temporary as \env{lateximage} is used.
%
% \begin{description}
% \item [When \pkg{lwarp} is loaded in print or HTML mode:]
%	\cs{LWR@restoreorigxcolor} and \cs{LWR@restoremoreorigxcolor} are defined as null.
%	\Cref{sec:xcolordefaults}
% \item [When \pkg{xcolor} is loaded in print mode:] \
%	No special actions are taken at the time that \pkg{xcolor} is loaded in
%	print mode, but see \cs{AtBeginDocument} below.
% \item [When \pkg{lwarp-xcolor} is loaded in HTML mode:] \
%	\pkg{xcolor}'s original definitions are saved for later restoration.
%	\cs{LWR@restoreorigxcolor} is defined to restore these definitions
%	for use inside a \env{lateximage}.
%	New \HTML-mode definitions are created for \cs{textcolor}, \cs{pagecolor},
%	\cs{nopagecolor}, \cs{colorbox}, \cs{colorboxBlock}, \cs{fcolorbox},
%	\cs{fcolorboxBlock}, and \env{fcolorminipage}.
% \item [\cs{AtBeginDocument} in print or HTML mode:]
%	See \Cref{sec:xcolorpatches}.
%	If \pkg{xcolor} has been loaded, the print-mode \cs{fcolorbox} is modified
%	to accept a background color of |none|, and additional definitions are created
%	for \pkg{lwarp}'s new macros print-mode macros \cs{colorboxBlock},
%	\cs{fcolorboxBlock}, and \env{fcolorminipage}.  The \HTML\ versions of these
%	macros will already have been created by \pkg{lwarp-xcolor} if it has been loaded.
%	For use inside an \HTML\ \env{lateximage}, \cs{LWR@restoremoreorigxcolor}
%	is defined to temporarily set these functions to their print-mode versions.
% \item [In a \env{lateximage} in HTML mode:] \
%	\cs{LWR@restoreorigxcolor} and \\ \cs{LWR@restoremoreorigxcolor} are used to
%	temporarily restore the print-mode definitions of \pkg{xcolor}'s functions.
%	See \cs{LWR@restoreorigformatting} on page \pageref{sec:restoreorigformatting}.

% In the user's document preamble, \pkg{lwarp} should be loaded
% after font-related setup.
% \watchout[font size]
% During \HTML\ conversion, this font is used by \pkg{lwarp}
% to generate its initial \PDF\ output containing \HTML\ tags,
% later to be converted by |pdftotext| to a plain text file.
% While the text may be in any font which |pdftotext| can read, the math is
% directly converted into \SVG\ images using this same user-selected font.
% |xfrac| below is set for the Latin Modern (lmr) font.
% If another font is used, it may be desirable to redefine
% \cs{xfracHTMLfontsize} with a different em size.




% \DescribeMacro{\sfrac} \oarg{instance} \marg{num} \oarg{sep} \marg{denom}
%
% A text-mode instance for the default font is provided below.
% The numerator and denominator formats are adjusted to encase everything
% in \HTML\ tags.  \cs{scalebox} is made null inside the numerator and
% denominator, since the \HTML\ tags should not be scaled, and we do not
% want to introduce additional \HTML\ tags for scaling.
%
% In math mode, which will appear inside a \env{lateximage}, no adjustments
% are necessary.
