% \noindent
% The \pkg{keyfloat} package provides a key/value user interface for quickly
% creating figures with a single image each, figures with arbitrary contents,
% tables, subfloats, rows of floats, floats located [H]ere,
% floats in the [M]argin, and floats with text [W]rapped around them.
%
% Key/value combinations may specify a caption and label, a width proportional
% to \cs{linewidth}, a fixed width and/or height, rotation, scaling, a
% tight or loose frame, an \cs{arraystretch}, a continued float,
% additional supplemental text,
% and an artist/author's name with automatic index entry.
% When used with the \pkg{tocdata} package, the name also appears in the
% List of Figures.
%
% Floats may be placed into a row environment, and are
% typeset to fit within the given number of columns,
% continuing to the next row if necessary.
% Nested sub-rows may be used to generate layouts such as
% two small figures placed vertically next to
% one larger figure.
%
% Subfloats are supported by two environments.
%
%
% \bigskip
%
% \noindent
% As an example, a typical command to include a figure with a framed image of half \cs{linewidth}
% could be: \\
% \hspace*{1em}\verb|\keyfig*[hbp]{f,lw=.5,c={A caption},l={fig:label}}{image}|

%
% \section{Introduction}
%
% The \pkg{keyfloat} package simplifies the creation
% of \LaTeX\ floats, while still allowing a number of useful features.
%
%
% \subsection{A Problem with Floats}
%
% When including a figure with a graphics image into a document,
% the user typically enters something such as:
% \begin{verbatim}
% \begin{figure}
% \centering
% \includegraphics[width=3in]{filename}
% \caption{A Figure}
% \label{fig:somelabel}
% \end{figure}
% \end{verbatim}
% \unskip
%
% When doing that often enough, it makes sense to factor the common code:
% \begin{verbatim}
% \onefigure[3in]{filename}{A Figure}{fig:somelabel}
% \end{verbatim}
% \unskip
% 
% Expanding the capability of \cs{onefigure} via \pkg{xparse} can lead to the general case of:
% \begin{verbatim}
% \onefigure*[loc](width){filename}(add'l text)[shortcap]{caption}*[label]
% \end{verbatim}
% \unskip
% Attempting to add additional features such as frames and continued floats
% hits the limit of nine parameters for a \TeX\ macro,
% requiring that new features use some kind of change-state macros instead.
% Attempting to support rows of floats or subfloats only made things more complicated still.
% 
% A key/value system solves the problem of adding more features,
% does not require much additional typing, is a more self-documenting
% syntax, and allows the sharing of keys with subfloats as well.
% Thus, the \pkg{keyfloat} package.
%
% \subsection{The \pkg{keyfloat} Package}
% 
% Using \pkg{keyfloat}, the first example above becomes:
% \begin{verbatim}
% \keyfig{w=3in,c=A Figure,l=fig:somelabel}{filename}
% \end{verbatim}
% \unskip
% 
% The \cs{onefigure} example above becomes:
% \begin{verbatim}
% \keyfig*[loc]{w=width,t={add'l text},sc=shortcap,cstar=caption,
%     l=label}{filename}
% \end{verbatim}
%
% \subsection{Features}
%
% The macros and environments provided by \pkg{keyfloat} include:
% \begin{description}
% \item[\cs{keyfig}:] A figure with an image.
% \item[\cs{keyfigbox}:] A figure with arbitrary contents.
% \item[\cs{keyparbox}:] A ``figure'' without a caption, useful
%	to place uncaptioned text inside a group,
% \item[\cs{keytab}:] A table.
% \item[keyfigure:] A figure environment.
% \item[keytable:] A table environment.
% \item[keyfloats:] A group of rows and columns of floats.
% \item[keysubfigs:] A figure containing a group of rows and columns of subfigures.
% \item[keysubtabs:] A table containing a group of rows and columns of subtables.
% \item[marginfigure:] A figure environment placed into
%	the margin.\footnote{\env{marginfigure} and \env{margintable}: The environments
%	provided by the |tufte-book| class are used if loaded,
%	otherwise \pkg{keyfloat} provides its own versions.}
% \item[margintable:] A table environment placed into the margin.
% \end{description}
%
% Additional features include:
% \begin{itemize}
% \item Rows and columns of floats may be generated by placing them inside a \env{keyfloats}
% environment.
% \item Subfloats may be generated by placing them inside a \env{keysubfigs}
% or \env{keysubtabs} environment.
% \item Dynamic layout: The number of columns is specified. Extra
% 	floats are placed onto additional rows as needed, with the final row
% 	adjusted to compensate for leftovers.
% \item Floats may be placed [H]ere.
% \item Floats may be placed in the [M]argin.
% \item Floats may be placed with text [W]rapped around them.
% \item Floats may be starred to span two columns.
% \item Continued floats may be used to repeat the previous float number.
% \item A figure may contain an image, with additional sizing, rotation, and a frame.
% \item Tables may be stretched.
% \item Boxes of arbitrary contents may be assigned a width and framed.
% \item Floats may be moved into and out of the grouping environments as needed.
% \item An artist/author's name may be added to a figure and the index.
% \item If the \pkg{tocdata} package is loaded (use v0.12+),
%	the name is also added to the \acro{LOF}.
% \item Additional descriptive text may be added as well.
% \item Frames may be customized.
% \end{itemize}
%
% A large number of examples are provided, each showing \LaTeX\ source and
% \margintag{examples}
% the resulting float.
%
% A customized index is included at the back of the documentation.
% \margintag{index}
%
% Blue margin tags are used to help quickly find information, and often
% \margintag{margin tags}
% indicate the destination of index entries.
%
% Several warnings are noted in the text.  Watch out for these special cases.
% \watchout[warnings]
%
% See the ``troubleshooting'' section of the index for help
% \margintag{problems}
% with specific problems which may occur.

% \section{Using the \pkg{keyfloat} Package}
%
% \subsection{Loading \pkg{keyfloat}}
%
% \pkg{keyfloat} is loaded with the usual command:
% \begin{verbatim}
% 	\usepackage{keyfloat}
% \end{verbatim}
%
% If you wish to have artist's names appear in the table of contents,
% as provided by the \pkg{tocdata} package,
% load either \pkg{tocloft} or \pkg{titletoc},
% followed by \pkg{tocdata}, then \pkg{keyfloat}:
% \begin{verbatim}
% 	\usepackage{titletoc}% or titletoc
% 	\usepackage{tocdata}
% 	\usepackage{keyfloat}
% \end{verbatim}
% 
% 
% \subsection{Macros and Environments}
%
% \DescribeMacro{\keyfig} * \oarg{loc} \marg{\keyvalsarg} \marg{image filename} \\
% A macro to generate a figure with an image from a file.
%
% \DescribeMacro{\keyfigbox} * \oarg{loc} \marg{\keyvalsarg} \marg{box contents} \\
% A macro to generate a figure with arbitrary paragraph contents.
% See \cref{ex:keyfigbox}.
%
% \DescribeMacro{\keyparbox} * \oarg{loc} \marg{\keyvalsarg} \marg{box contents} \\
% A macro to generate a figure with arbitrary paragraph contents,
% but no number or caption. This is equal to a \cs{keyfigbox} with |cstar={}|.
% Mostly useful to add supplemental information inside a row of floats or subfloats.
% See \cref{ex:keyparbox}.
%
% \DescribeMacro{\keytab} * \oarg{loc} \marg{\keyvalsarg} \marg{tabular contents} \\
% A macro to generate a table with tabular contents.
% Usually use the \env{keytable} environment instead.
%
% \DescribeEnv{keyfigure} * \oarg{loc} \marg{\keyvalsarg} \\
% An environment to generate a figure with arbitrary contents.
% Useful for multi-paragraph contents.
% See \cref{ex:keyfigure}.
%
% \DescribeEnv{keytable} * \oarg{loc} \marg{\keyvalsarg} \\
% An environment to generate a table with arbitrary contents.
% Useful for larger tables.
% See \cref{ex:keytable}.
%
% \medskip\hrule
% The above macros and environments may be used by themselves,
% or inside the following \env{keyfloats}, \env{keysubfigs}, or
% \env{keysubtabs} environments.
% \medskip\hrule
%
%
% \DescribeEnv{keyfloats} * \oarg{loc} \marg{num columns} \\
% A group of figures or tables typeset in rows.  May be nested.
% See \cref{ex:keyfloats}.
%
% \DescribeEnv{keysubfigs} * \oarg{loc} \marg{numcols} \marg{keys} \\
% A group of subfigures typeset in rows.
% May not be nested.
% See \cref{ex:keysubfigs}.
%
% \DescribeEnv{keysubtabs} * \oarg{loc} \marg{numcols} \marg{keys} \\
% A group of subtables typeset in rows.
% May not be nested.
% See \cref{ex:keysubtabs}.
%
% \DescribeEnv{marginfigure} \oarg{offset} \\
% A figure placed into the margin, with an optional vertical offset.
% \cs{keyfloat} uses the version provided by the |tufte-book| class if available,
% or provides its own version otherwise.
% See \cref{ex:marginfigure}.
%
% \DescribeEnv{margintable} \oarg{offset} \\
% A table placed into the margin, with an optional vertical offset.
% \cs{keyfloat} uses the version provided by the |tufte-book| class if available,
% or provides its own version otherwise.
% See \cref{ex:margintable}.
%
% \bigskip\hrule
%
% \DescribeArgument{*}
% The star option create floats which span both columns in a two-column
% document.
%
% \DescribeArgument{{[H]}}
% The |[H]| location forces a figure to be ``Here'', in the
% form of a minipage instead of a float.  A caption, label, etc.\ may
% still be assigned.
%
% \DescribeArgument{{[M]}}
% The |[M]| location places the float into the margin.  When the |tufte-book| class
% is used, its \env{marginfigure} and \env{margintable} environments are used,
% otherwise \pkg{keyfloat} provides and uses its own versions of the same environments.
% See \cref{ex:keyfigm,ex:keytablem}.
%
% \DescribeArgument{{[W]}}\DescribePackage{wrapfig}
% The |[W]| location wraps text around the float.  Use this just before the start of
% a paragraph with contents large enough to wrap around the float.  Do not use this
% inside a list environment.  Select placement with the |wp| key; see
% the \pkg{wrapfig} package documentation for more information.
%
% \DescribeArgument{{[loc]}}
% The star and [loc] options are ignored for floats inside a \env{keyfloats},
% \env{keysubfigs}, or \env{keysubtabs} environment.  Note that these
% container environments may have their own star and [loc] options.

% \subsection{Customization}
%
% \subsubsection{Custom Frames}
% \label{sec:customframes}
%
% \index{frame>custom}
%
% There are two user-redefinable framing macros: \\
% \hspace*{2em}\cs{KFLTtightframe} and \cs{KFLTlooseframe}
%
% A float's contents are placed into a box,
% which is passed to either of these two macros
% depending on the key |f| or |tf|.
%
% Each macro takes one argument and frames it.
%
% Each macro has an associated \LaTeX\ length: \\
% \hspace*{2em}\cs{KFLTtightframewidth} and \cs{KFLTlooseframewidth}
%
% These lengths must be redefined to the expected
% total frame width, equal to the frame thickness plus
% separation.
%
% The defaults definitions are:
% \begin{Verbatim}[gobble=2]
% \newcommand{\KFLTtightframe}[1]{%
% \setlength{\fboxsep}{0pt}%
% \setlength{\fboxrule}{.4pt}%
% \fbox{#1}%
% }
% \setlength{\KFLTtightframewidth}{.4pt}

% \setlength{\fboxsep}{3pt}%
% \setlength{\fboxrule}{.4pt}%
% \fbox{#1}%
% }
% \setlength{\KFLTlooseframewidth}{3.4pt}
% \end{Verbatim}
%
% See \cref{ex:customframe} for an example
% created with the \pkg{mdframed} package,
% and \cref{ex:customshadow} for an example
