%
% \changes{v1.1}{02 Nov 1988}{Initial revision.}
%
% \changes{v1.2}{30 Aug 1989}{Added a separate bottom margin and
% expanded the comments.}
% 
% \changes{v1.3}{22 Oct 1990}{Changed test for empty subcaption inside
% of \cmd{\@subfigure} to compare tokens and not the subcaption vs.\
% \cmd{\@empty}. The former (incorrect) test caused an error when the
% first two letters of the subcaption were the same.}
% 
% \changes{v1.4}{27 Jun 1992}{Added a hack to allow the \cmd{\label}
% command to be used within the body of the subfigure giving a
% reference label in the form \cmd{\arabic{thefigure}\thesubfigure}.
% Added standard file header for style.}
%
% \changes{v1.5}{11 Aug 1992}{Fixed a bug which caused a problem with
% subcaptions that contained expressions like \cmd{\sqrt};  This was
% pointed out by Tom Scavo (scavo\@cie.uoregon.edu).  A separate bug
% was fixed which caused different sized subcaptions to be misaligned;
% This problem was pointed out by Simon Marshall
% (S.Marshal\@Hull.ac.uk).  Also cleaned up the code a mite and
% {\bf changed} the figure spacing so that if no optional section is
% given, then the figure is only followed by \cmd{\subfigbottomskip}
% and not that plus $(\cmd{\subfigcapskip}+\cmd{\strut}\hbox{height})$.
% This should make it easier to adjust spacing as desired.}
%
% \changes{v1.6}{13 May 1993}{Changed to use the \cmd{\thefigure}
% command in building the referenced label.  The old form caused a
% problem when used with the report.sty as pointed out by Andrew
% Anselmo (anselmo\@cumesb.mech.columbia.edu).  Also modified to
% restrict the scope of the subfigure \cmd{\label} to the body of the
% subfigure.  Added \cmd{\@thesubfigure} to allow a separate labeling
% of the subfigure in the figure and in the text.  By default it is
% the same as \cmd{\thesubfigure} with space appended.  Added some
% code to print the subfigure captions to the List-of-Figures file
% if desired.  Finally, added the corresponding support for subtables 
% as well as subfigures.  NOTE: the optional subcaption is now a moving
% argument and any fragile commands that appear in the subcaption must
% be preceded by a \cmd{\protect} (just like that of the \cmd{\caption}
% command).}
% 
% \changes{v2.0}{06 Mar 1995}{This version of \cmd{\subfigure} is the
% first to be ported to \LaTeXe\ (with backward compatibility to
% \LaTeX2.09).  \cmd{\subfigure} and \cmd{\subtable} are now identical
% and the environment controls internal differences between them.  Now,
% the subcaption setting portion of \cmd{\@subfloat} is broken into the
% separate commands \cmd{\@makesubfigurecaption} and
% \cmd{\@makesubtablecaption} to allow a separate hook for the
% modification of how the subcaption is constructed and to allow the
% subtable and subfigure captions to be different.  In addition, support
% of the \Lopt{normal}, \Lopt{hang}, \Lopt{center}, \Lopt{centerlast},
% \Lopt{nooneline}; \Lopt{scriptsize}, \ldots, \Lopt{Large}; \Lopt{up},
% \Lopt{it}, \Lopt{sl}, \Lopt{sc}, \Lopt{md}, \Lopt{bf}, \Lopt{rm},
% \Lopt{sf}, and \Lopt{tt} package options were added for compatibility
% with the caption.sty by H.A. Sommerfeldt.}
% 
% \changes{v2.1}{23 Jan 2002}{Upgraded to fix a \cmd{\protect} bug that
% crept in due to changes in \LaTeXe\ and to enhance the interaction
% with the ``List-of'' files.  Backward compatibility with \LaTeX2.09 is
% \textbf{not} supported.  This version allows optional subcaption
% strings for the ``List-of'' files and the companion captcont.sty
% allows further extensions.  Added check for \Lfile{subfigure.cfg} file
% for automatic configuration.  Added more options for adjustment of the
% look-and-feel of the subcaption.  Added the ability to independently
% move the float caption and subcaption before or after the figure.
% Removed extra space from the top of a figure at the top of a page and
% some accidental whitespace.  Reduced the default space around the
% figure and made it actual skips.  Updated the documentation to

% \noindent
% This article documents the \LaTeX\ package `\Lpack{hhsubfigure}', which
% provides support for the inclusion of small, `sub', figures and
% tables.  It simplifies the positioning, captioning and labeling of
% such objects within a single \Lenv{figure} or \Lenv{table}
% environment.  In addition, this package allows such subcaptions to be
% written to a List-of-Figures or List-of-Tables if desired.  The
% `\Lpack{hhsubfigure}' package also cooperates with the `\Lpack{caption}'
% and `\Lpack{caption2}' packages by H.A. Sommerfeldt
% \cite{Somm95a,Somm95b}, the `\Lpack{ccaption}' and `\Lpack{tocloft}'
% packages \cite{Wils01,Wils01B} by Peter Wilson, the `\Lpack{hyperref}'
% package by Sebastian Rahtz \cite{Raht02}, the `\Lpack{captcont}' package
% \cite{Coch02}, and should be compatible with all other packages that
% modify or extend the \Lenv{float} environment or the \cmd{\caption} or

% 
% This package provides support for the manipulation and reference of
% small or `sub' figures and tables within a single \Lenv{figure} or
% \Lenv{table} environment\@.\footnote{Section~\ref{sec:customfloat}
% describes how to add support for additional \Lenv{float}
% environments.}  It is convenient to use this package when your
% subfigures are to be separately captioned, referenced, or when such
% subcaptions are to be included in the List-of-Figures.
% 
% Before using the \Lpack{hhsubfigure} package, consider the following to
% see if you really need it.  If you simply want to center your figure,
% then you can use |\centerline|, |\centering| or the \Lenv{center}
% environment to do so.  If your figure has a short width or if you wrap
% your figure in a |\parbox| or a \Lenv{minipage} of a short width, then
% you can place multiple figures or tables side-by-side.  For example,
% the following will put two images side-by-side in a single figure as
% shown in figure~\ref{fig:1figs}:\footnote{You might have to use the
% optional position arguments `[b]' or `[t]' if the figures are of
% different heights.}
%
% \begin{verbatim}
%     \begin{figure}%
%       \centering
%       \parbox{1.2in}{...figure code...}%
%       \qquad
%       \begin{minipage}{1.2in}%
%         ...figure code...
%       \end{minipage}%
%       \caption{Here are two figures side-by-side.}%
%       \label{fig:1figs}%
%     \end{figure}
% \end{verbatim}
% \vspace{-1\baselineskip}
% \begin{figure}^
%   \abovecaptionskip=6pt^
%   \centering
%   \parbox{1.2in}{^
%     \fboxsep=-\fboxrule
%     \fbox{\hbox to 1.2in{\vbox to 15mm{\null\vfil}\hfil}}}^

%   \caption{Here are two figures side-by-side.}^
%   \label{fig:1figs}^
%   \vspace{-10pt}
% \end{figure}
% 
% \noindent
% Further, if you place the caption inside the |\parbox| or
% \Lenv{minipage}, then the width of the caption will be limited to the
% width of the parbox or minipage as shown in figures~\ref{fig:2figsA}
% and \ref{fig:2figsB}:
% 
% \begin{verbatim}
%     \begin{figure}%
%       \centering

%         \label{fig:2figsA}}%
%       \qquad
%       \begin{minipage}{1.2in}%
%         ...figure code...
%         \caption{Second.}%
%         \label{fig:2figsB}%
%       \end{minipage}%
%     \end{figure}%

% To use this package place
% \begin{quote}
%   |\usepackage|\oarg{options}\marg{hhsubfigure}

% in the preamble of your document.  The supported options are shown in
% table~\ref{tab:options}.
% \DescribeMacro{\subfigure}
% \DescribeMacro{\subtable}
%  Within a \Lenv{figure} or \Lenv{table}
% environment, you can use the following commands to create a subfigure
% or subtable ``box'' with an optional subcaption underneath.
% \vspace{-2pt}
% \begin{quote}
%   |\subfigure|\oarg{list\_entry}\oarg{subcaption}\marg{figure}\\
%   |\subtable|\oarg{list\_entry}\oarg{subcaption}\marg{figure}
% \end{quote}
% \vspace{-2pt}
% 
% \noindent
% If a subcaption argument is given (including the null subcaption
% `{\ttfamily [$\;$]}') then the subfigure is labeled with a counter
% formatted by the command `|\thesubfigure|' which returns, by default,
% `(a)', `(b)', etc.  The counter used for labeling the subfigures is
% \Lcount{hhsubfigure} and is incremented for each subfigure regardless of
% whether a subcaption was printed. The internals of the |\subtable|
% command are symmetric to those of the |\subfigure| command.  Further,
% if a List-of-Figures (or List-of-Tables) is generated, then the
% \meta{list\_entry} argument controls how the caption text is used
% there.  Table~\ref{tab:calling} shows the possibilities.

% If you wish to reference a specific subfigure or subtable, you can
% include a |\label| inside the body of either the \meta{subcaption} or
% \meta{figure} argument to the command (but not the \meta{list\_entry}
% argument).  If supplied by itself, the \meta{subcaption} is a ``moving
% argument''\footnote{See \cite[\textsection~4.7 and
% \textsection~C.1.3]{Lamp94} for a more detailed description of
% ``moving arguments'' and ``fragile'' commands.} and, therefore, any
% ``fragile'' commands contained within it must be |\protect|'ed.  If
% the \meta{list\_entry} argument is supplied, then the
% \meta{subcaption} is not a ``moving argument''; however, the
% \meta{list\_entry} is.
% 
% {\bf Note:} since the |\subfigure| and |\subtable| commands have optional
% arguments, delimited with square brackets, before their required argument,
% you cannot use the `]' character at the top level of either the
% \meta{subcaption} or \meta{list\_entry} argument.  To overcome this
% problem, you must wrap the portion of the text containing the `]'
% character (or the entire argument), in a pair of curly brackets (see
% \cite[\textsection~C.1.1]{Lamp94} for more detail).  For example:
% 
% \begin{verbatim}
%   \subfigure[This does not $sqrt[3]{8}$ work.]{... figure text ...}
%   \subfigure[This works {$sqrt[3]{8}$} fine.]{... figure text ...}
%   \subfigure[{This also works $sqrt[3]{8}$ fine.}]{... figure text ...}
% \end{verbatim}
% 
% One final note, the |\subfigure| and |\subtable| commands are
% actually identical and it is the surrounding environment that defines 
% actually identical and it is the surrounding environment that defines 
% whether a subtable or subfigure will be generated and not which command 
% is used.  At the user level, the choice of names is purely cosmetic
% (and historical).  Therefore you can use |\subfigure| for any float
% ({\it e.g.\/}, \Lenv{figure}, \Lenv{table}, or other) environment.

% \subsection{Format Options}
% \label{sec:format}
%
% There are six options for formatting the layout of the caption label
% and text.  The first is \Lopt{normal}, which produces the style shown
% in figure~\ref{fig:format-01}.  The other options may be used in
% various combinations to produce the layouts shown in
% figures~\ref{fig:format-02} thru \ref{fig:format-14}.  Note that some
% combinations, like \Lopt{center} and \Lopt{centerlast} do not make
% sense since \Lopt{center} overrides \Lopt{centerlast}.  Also, 
% \Lopt{nooneline}, when combined with either \Lopt{center} or
% \Lopt{centerlast} has no effect (unless the \Lopt{hang} option is 
% also set); and, \Lopt{raggedright} overrides both \Lopt{center} and
% \Lopt{centerlast}.

% \subsection{Font Size and Style Options}
% \label{sec:font}
% 
% There are twenty-four options for setting the font of the subcaption.
% The first six set the size of both the subcaption label and text.
% They are: \Lopt{scriptsize}, \Lopt{footnotesize} (default),
% \Lopt{small}, \Lopt{normalsize}, \Lopt{large}, and \Lopt{Large}.
% Their effect is shown in figure~\ref{fig:font1}.
% 
% The next nine, \Lopt{rm}: \Lopt{sf}, \Lopt{tt}, \Lopt{md}, \Lopt{bf},
% \Lopt{up}, \Lopt{it}, \Lopt{sl}, and \Lopt{sc}, set the family, series
% or shape of the subcaption label, as shown in
% figures~\ref{fig:font2A}--~\ref{fig:font2I}.  The last nine:
% \Lopt{RM}, \Lopt{SF}, \Lopt{TT}, \Lopt{MD}, \Lopt{BF}, \Lopt{UP},
% \Lopt{IT}, \Lopt{SL}, and \Lopt{SC}, do the same for the text of the
% subcaption, as shown in figure~\ref{fig:font2J}--\ref{fig:font2R}.
% These size and style options may be combined in 3456 ways to set the
% label and text of the subcaption (as long as the selected font
% combination exists\@!)  The font family for the text and label may be
% set as roman (\Lopt{rm}/\Lopt{RM}), sans serif (\Lopt{sf}/\Lopt{SF}),
% and typewriter (\Lopt{tt}/\Lopt{TT}).  These may be combined with
% those for the font series, medium (\Lopt{md}/\Lopt{MD}) and bold
% (\Lopt{bf}/\Lopt{BF}); and the font shape, upright
% (\Lopt{up}/\Lopt{UP}), italic (\Lopt{it}/\Lopt{IT}), slanted
% (\Lopt{sl}/\Lopt{SL}), and small caps (\Lopt{sc}/\Lopt{SC}).

% \subsection{Caption Position Options}
% \enlargethispage{12pt}^finalhack
% \label{sec:position}
% 
% There are eight options that control the {\em position\/} of the
% subcaption and how the subcaption {\em numbering\/} is related to the
% ``containing'' figure or table's caption.  The following shows only
% the subfigure-related options, but the subtable options are symmetric.
% 
% The first option, \Lopt{figbotcap} tells the subfigure command that
% the ``containing'' figure's |\caption| occurs {\bf after} the
% subfigures.  This information is needed to decide if the current
% figure counter shows the number for the last figure (\Lopt{figbotcap})
% or for the current one (\Lopt{figtopcap}, see below).
% 
% The second option, \Lopt{figtopcap} tells the subfigure command that
% the ``containing'' figure's |\caption| occurs {\bf before} the
% subfigures.  The subcaption is automatically placed below the figure
% for each of these options.
% 
% The third option, \Lopt{FIGBOTCAP}, is similar to \Lopt{figbotcap},
% except that it also forces the subcaption to be placed under the
% figure.  This is the default setting for figures (and \Lopt{TABBOTCAP}
% for tables) and is shown in figure~\ref{fig:position1}.
% 
% The fourth option, \Lopt{FIGTOPCAP}, is similar to \Lopt{figtopcap},
% except that it forces the subcaption to be placed above the figure
% box.  (While not the default, it is the preferred format for tables,
% which uses the option \Lopt{TABTOPCAP}\@.)  An example of this option
% is shown in figure~\ref{fig:position2}.  Note that the baseline of the
% subfigure is along the top of the two subfigures.  See
% section~\ref{sec:custom-position} for another way of positioning the
% caption when captions are placed above the figure or table.

% \subsection{Recent Changes and Backward Compatibility}
% \enlargethispage{24pt}^finalhack
% \label{sec:back-compat}
% 
% There are some significant changes in this version of the
% \Lpack{hhsubfigure} package.  One of them was to pack the subfigure
% tighter together by removing the space at the top of the subfigure at
% the beginning of a page, or minipage, and to reduce the spacing around
% the subfigure, see table~\ref{tab:spacing}.  If you have been using an
% older version of the \Lpack{hhsubfigure} package ({\it i.e.\/}, version
% 2.0 or eariler) than the default (\Lopt{loose}) setting will not cause
% any change in your existing documents.\footnote{If you have been using
% a beta release version of \Lpack{subfigure} 2.1, than you will need to 
% use the \Lopt{tight} option in order to maintain the ``look-and-feel'' 
% that you are used to.}
% 
% If you want to use the new and preferred, \Lopt{tight} option, your
% subfigures will take up less space and should provide a more balanced
% visual appearance for your paper.
% 
% The second significant change is the ability to make the text on the
% List-of-Figures page different than that in the subcaption.  The use
% of a second optional argument to the |\subfigure| command is shown in
% table~\ref{tab:calling}.  This should not cause any compatibility
% problems.
% 
% The third significant change is the it is now possible to have the
% captions and subcaptions come before or after the corresponding
% figure/table portion.  While the default settings support the old view
% of the subcaptions following the figure/table and, in turn, followed
% by the main caption.  The preferred format is for figures to retain
% that layout and for tables to have both their subcaption and main
% captions come before the table portion.  This preferred setting may be
% specified by adding the option \Lopt{TABTOPCAP} when loading the
% \Lpack{hhsubfigure} package.
% 
% The fourth update is that the font style options have been generalized
% so that an option from each of the family, series and shape, may be
% combined, as long as that combination exists; and you can set the font
% of the label and text separately.  In addition, the the |\space| that
% separated the label from the text in the subcaption has been replaced
% with a horizontal skip of |\subfiglabelskip| which has the default
% value of |0.33em plus 0.07em minus 0.03em|.  This extension should not
% cause any compatibility problems.
% 
% The last major change is that there is now a |\subref| command that
% allows a reference to the subfigure without the figure number.  An
% example of the use of this command is shown later in
% section~\ref{sec:ex3}.  Associated with this change is that the
% |\label| command will accept an optional argument, for use with the
% \Lpack{hyperref} package, when used within the scope of the
% |\subfigure| or |\subtable|, see section~\ref{sec:hyperref} for details.

% The \Lpack{hhsubfigure} package checks for and loads a configuration

% will look for classes or packages (see

% file tries to look unchanged from older versions.  In order to
% have it automatically use the preferred settings, you can add a

% 
% \subsection{Frequently Asked Questions}
% \label{sec:faq}
% 
% The four most frequently asked questions about the \Lpack{hhsubfigure}
% package are:
% 
% \begin{enumerate}
%   \item ``My subfigures are not aligned along their bottoms. Why?''
% 
%     Remember! The \Lpack{hhsubfigure} package aligns subfigure along
%     their baselines with the subcaption (if any) sticking out above or
%     below.  The above problem is usually due to using a \Lenv{minipage},
%     \Lenv{tabular} or \Lenv{array} environment that, by default,
%     places the baseline at the center of the box that it generates.
%     If the two subfigures are different sizes, or if one subfigure is
%     generated in some other way with its baseline not at the expected
%     place (perhaps an |\includegraphics|), then the subfigures will be
%     misaligned.  One solution is to use the environment options `[t]'
%     or `[b]' to move the baseline to the top or bottom rather than the
%     center.
% 
%   \item ``How can I get my figures/subfigures to line up the way I want?''
% 
%     A similar question, but this one is caused by extra whitespace in
%     the source text generating spaces next to the figures, and |\par|'s
%     generated by blanklines.  The main thing is {\it be aware\/} that 
%     extra whitespace can move figures and subfigures around, sometimes 
%     a lot and sometimes just a little so that they look ``wrong''.  
%     Placing too many `\%'s at the end of the lines is better than too 
%     few in the figure and table environments.  (See the discussion of 
%     ``white space'' in section~\ref{sec:examples}.)
% 
%   \item ``I have too many subfigures for one page, How can I spread
%           them over two or more pages and continue the numbering?''
%     \begin{description}
%       \item[Option 1:] Adjust the \Lcount{figure} and \Lcount{subfigure}
%                        counters (or the \Lcount{table} and 
%                        \Lcount{subtable} counters) as needed before and
%                        after each figure (or table) See, for example 
%                        \emph{Using Imported Graphics in \LaTeXe}
%                        \cite[\textsection~30]{Reck97}.
%       \item[Option 2:] Use the \Lpack{ccaption} package by Peter Wilson 
%                        \cite{Wils01}.
%       \item[Option 3:] Use the simpler \Lpack{captcont} package by
%                        Steven Cochran \cite{Coch02}.
%     \end{description}
%     All of these options work well.  Of the packages, the 
%     \Lpack{ccaption} package is bigger and offers more control over 
%     what is done (and things to do) at the expense of being a little 
%     harder to use.  The \Lpack{captcont} package is easier to use, 
%     but only provides for continued floats.
% \newpage^finalhack
%   \item ``Why do I get a garbled caption or an error when I use
%           square brackets?''
% \vspace{-2pt}
% \begin{verbatim}
%   \subfigure[SHIFT: ``register[3] $<<=$ 3;'']{... figure text ...}
% \end{verbatim}
% \vspace{-12pt}
%     Since the |\subfigure| and |\subtable| commands have optional 
%     arguments, delimited with square brackets, before their required
%     argument, you cannot use the `]' character at the top level of
%     either the \meta{subcaption} or \meta{list\_entry} argument.  To
%     overcome this problem, you must wrap all or the portion of the text
%     containing the `]' character, in a pair of curly brackets
%     (see \cite[\textsection~C.1.1]{Lamp94} for more detail). For example:
% \begin{verbatim}
%   \subfigure[SHIFT: ``register{[3]} $<<=$ 3;'']{... figure text ...}
% \end{verbatim}
% \vspace{-16pt}
% \noindent
% or
% \vspace{-4pt}
% \begin{verbatim}
%   \subfigure[{SHIFT: ``register[3] $<<=$ 3;''}]{... figure text ...}.
% \end{verbatim}
% \vspace{-12pt}
% \end{enumerate}
% 
% \section{Three Examples}
% \label{sec:examples}
% 
% The easiest way to show the use of this package is to give a few
% examples.  The two most important things to remember when working
% with the \Lpack{hhsubfigure} package are that (1) the subfigures are
% aligned along their baselines (see figure~\ref{fig:layout} and
% section~\ref{sec:customlayout}) and (2) that whitespace in the
% \Lenv{figure} environment are significant and affect the layout.
% 
% The baseline of the subfigure is usually at the bottom of the
% subfigure or (when the subcaption appears at the top) at the bottom of
% the subcaption {\em and\/} the |\subfigcapskip| space---which is usually
% the same as the top of the subfigure.  However sometimes, especially
% when using the \Lenv{tabular}, \Lenv{array}, or \Lenv{minipage} 
% environments to build the figure, the baseline appears elsewhere.  The 
% above environments are all aligned at their center by default but that 
% may be changed with the optional `{\bf [t]}' or `{\bf [b]}' arguments.  
% As a last resort you can wrap all of your figures in a |\vtop| box with 
% a |\vbox to 0pt{\null}| at the top followed by the figure.
% 
% If your figure is not quite centered or where you want it to be, the
% problem is often a space character being placed to one side or the
% other of the figure.  Some general rules of thumb are:\footnote{See
% chapters 7 and 8 of ``The \TeX book'' \cite{Knut86} for details.}
% \begin{itemize}\itemsep0pt
%   \item Two end-of-lines following each other (ignoring any
%         whitespace) are turned into a |\par| or paragraph break.
%   \item Multiple whitespace (including the end-of-line) are
%         compressed into a single space.
%   \item The spaces after a macro command name ({\it e.g.\/}, |\foo|) 
%         are ignored.
%   \item A `\%' character at the end of the line suppresses the
%         end-of-line and all of the spaces (if any) at the
%         beginning of the next line.
% \end{itemize}
% 
% To suppress significant extra whitespace, you can add some `\%'
% characters at the end of each line that doesn't end with a command name.
% This is more than is required, but extra `\%' usually don't cause a
% problem.
% 
% The other case where things are not correctly centered is when the
% subfigure uses only the label for the subcaption.  This is often the
% case when the description for each subfigure is given in the figure
% caption rather than in each subcaption.  In this case, the default
% label has the form `(a)\ \ ' where the trailing space is defined by
% |\subfiglabelskip|.  In this case the style should redefine this space
% as `0pt' so that the label is perfectly centered (see 
% section~\ref{sec:ex3}, below for an example).
% 
% \subsection{A Simple Example}
% \enlargethispage{12pt}
% 
% The first example, shown in figure~\ref{3figs}, specifies |\centering|
% \DescribeMacro{\subfigure}
% to horizontally center the set of subfigures, and uses |\\| and 
% some horizontal space (using |\qquad|) to control the placement of 
% the subfigures.  Note that the alignment of the top two subfigures
% is along the bottom of the figure portion of each.

% \subsection{A More Advanced Example}
% 
% A second example, shown in figure~\ref{fig:ex2}, demonstrates how to
% change the subfigure labels and have the subfigure captions printed in
% the List-of-Figures.
% 
% The first |\renewcommand| changes the reference to |\thesubfigure| to
% return both the figure number and the subfigure number separated with
% a period.  The next two |\renewcommand|'s turn off the |\p@subfigure|
% (since it is now included in |\thesubfigure| and adds the colon and
% space to the subfigure label.  Later in the file, the
% \Lcount{lofdepth} is set to ``2'' so allow the subfigure captions to
% show and the |\listoffigures| is loaded.  Finally, the \Lenv{figure}
% is defined and a little following text is given that refers to it.
% 
% \begin{verbatim}
%   \renewcommand{\thesubfigure}{\thefigure.\arabic{subfigure}}

% \subsection{An Example Without Subcaption Text}

% 
% The last example, shown in figure~\ref{fig:ex3}, demonstrates a
% \DescribeMacro{\subref}
% \DescribeMacro{\Subref}
% \enlargethispage{12pt}
% commonly required format where the subfigure are just labeled and the
% description occurs in the main caption.  This is easy to do by using
% the ``empty'' optional caption arguments ``[\space ][\space ]''.  This
% creates a label for the subfigure in the text, but it does not show on
% the List-of-Figures page.  However, by default the caption may not be
% perfectly centered, so |\subfiglabelskip| is reduced to zero points to
% ensure that there is not any extra space hidden in the subcaption.  To
% refer to the subfigure label within the text or the main caption, you
% can use the |\subref| command, which is similar to the |\ref| command,
% but does not carry the figure number.  (The |\Subref| command is the
% same but sets it with |\subcaplabelfont|).

% \section{Customization}
% \label{sec:customization}
%
% The following sections describe the internal parameters used by the
% \Lpack{hhsubfigure} package to define the layout of the subfigures
% or tables, as well as the labels and captions the accompany them.
% In addition, adjustments to the entries on a ``List-of'' page and
% the addition of new \Lenv{float} environments are described.
% 
% Adjusting these values allows extensive customization of the
% \Lpack{hhsubfigure} package.  If you want to customize the package, an
% alternative to actually changing the code is to create a a file called
% \Lfile{subfigure.cfg} and place it anywhere that \LaTeX\ will look for
% classes or packages.  Any changes placed in the file will affect the
% predefined parameters and you can override the default settings.  Any
% user options will be processed after this file is loaded.
% 
% In order to change the major commands in the \Lpack{hhsubfigure} package
% with this configure file, you will need to use the |\AtEndOfPackage|
% command to defer that portion of your changes until the end of the
% package.
% 
% \subsection{Changing the Layout}
% \enlargethispage{15pt}^finalhack
% \label{sec:customlayout}
%
% \noindent
% The layout of the |\subfigure| or |\subtable| is defined by several
% internal values which may be changed to customize appearance of the
% object.  The following illustration shows the relationship of these
% values.  Figure~\ref{fig:layout-A} shows the standard layout with the
% caption following the figure.  The figure is vertically centered with
% |\subfigtopskip| of space added above, then |\subfigcapskip| of 
% space is added below the figure followed by the subcaption and, 
% finally, |\subfigbottomskip| of space added at the bottom.  The baseline
% is located at the bottom of the figure.  It is along this baseline that 
% adjacent subfigure boxes are aligned.  Figure~\ref{fig:layout-C} shows 
% the case where the caption precedes the figure ({\it ie.\/}, 
% |\subfiguretopcaptrue| or |\subtabletopcaptrue|).  In this case the
% various boxes and glue are reversed,$\!$\footnote{The \cmd{\subfigtopskip}
% and \cmd{\subfigbottomskip} actually follow the \Lif{figuretopcap}
% and \Lif{tabletopcap} flags, so that the actual top spacing used is
% \cmd{\subfigtopskip} when the flags are {\bf false} and 
% \cmd{\subfigbottomskip} when they are {\bf true}.}
% except that the |\subfigcapskip| is increased by |\subfigcaptopadj|.
% The other two cases, figures~\ref{fig:layout-B} and
% \subref{fig:layout-D}, show the cases where there is no caption.  Note
% that the |\subfigcapskip| is left out when there is no caption.
% Note also, for all of these cases, that the space at the top of the
% subfigure is automatically removed for items that are the first box 
% in a vertical list or other than the first box in a horizontal list.  
% This allows tighter packing of the subfigures and the full use of 
% the page or \Lenv{minipage}.
% 
% Each of these values |\subfigtopskip|, |\subfigcapskip|, and
% |\subfigbottomskip|; as well as |\subfigcapmargin| and
% |\subfiglabelskip| (the latter not shown in figure~\ref{fig:layout})
% may be changed from their defaults (see
% table~{\PrintIfDefined{tab:defaults}{\ref{tab:defaults}}{\ref{tab:spacing}}})
% to adjust the subfigure for the current layout style.  In addition,
% they may all assume negative values, which in some cases may solve
% problems with the layout.  Even though these constants are ``skips'',
% only the last two (|\subfigcapmargin| and |\subfiglabelskip|) will
% shrink or expand since the others assume their natural size in the
% subfigure box and are fixed at that size.

% \end{figure}
%
% \subsection{Adjusting the Subcaption}
% \label{sec:customlabel}
% 
% The subfigure label has three forms.  The first is the one that
% \DescribeMacro{\subref}
% \DescribeMacro{\Subref}
% appears in the text when you use the |\ref| command; the second is the
% one that appears on the List-of-Figures page and may be used to
% reference individual subfigures within the figure and subfigure captions,
% using the |\subref| or |\Subref| commands; and the third is the fully
% formatted version used under the subfigure as the label part of the caption.
% 
% The |\ref| command yields the string, saved by the |\label| command,
% composed by concatenating the value of |\p@subfigure| to
% |\thesubfigure|.  By default these are defined by: ``|\thefigure|''
% and ``|(\alph{subfigure})|'', respectively, which produces a reference
% of the figure number followed by the subfigure letter in parentheses.
% 
% The label used on the List-of-Figures page may be retrieved with the
% |\subref| command (this value is saved by the |\label| command when
% the |\label| command is used within the scope of the subfigure.  This is
% the string defined by |\@@thesubfigure|, which, by default, is the
% value ``|\thesubfigure|'' (or ``|(\alph{subfigure})|'').
%
% The label used with the subcaption text is defined by the internal
% value |\@thesubfigure|, which, by default, has the
% value\hfil\null\linebreak
% \centerline{``\cmd{\thesubfigure}\cmd{\hskip}\cmd{\subfiglabelskip}''.}
% It is prefixed by |\subcapsize\subcaplabelfont| and followed by the
% subcaption text which is set with |\subcapfont|.
%
% \changes{v2.1.4}{30 Apr 2002}{Changed the label and caption defaults
% from \cmd{\rmfamily}\cmd{\mdseries}\cmd{\upshape} to 
% \cmd{\familydefault}\cmd{\seriesdefault} \cmd{\shapedefault}.}
% Note that by default |\subcaplabelfont| has the default value
% ``|{\familydefault| |\seriesdefault\shapedefault}|''.  The package
% options described in table~\ref{tab:options} allow you to set these
% values for your paper.  If you update the |\@subfigure| command, you
% should include any separator character or spacing between the label
% and the start of the subcaption text.  The default is
% |\hskip\subfiglabelskip| placed after the label.
% 
% Finally, the text of the subcaption is prefixed by |\subcapfont| which
% may be changed using the set of nine lower-case font options described
% in table~\ref{tab:options}\@.$\!$\footnote{It is also prefixed by
% \cmd{\subcapsize} as part of the overall label and caption.} \ One other
% way of changing the layout of the lapel and caption is by replacing
% the |\@makesubfigurecaption| or |\@makesubtablecaption| command (which
% by default are identical).
% 
% \subsection{Adjusting the Subfigure and Subtable Counters}
% \label{sec:counters}
%
% To create some special effects, such as continuing the subfigure
% \DescribeMacro{\c@figure}
% \DescribeMacro{\c@table}
% numbering across several pages as part of one long continued figure,
% you can back off the number change from a caption with the command:
% \begin{quote}
%   |\addtocounter{|\Lcount{figure}|}{|-1|}|
% \end{quote}
% within the \Lenv{figure} environment.  In addition, you can adjust for 
% previous subfigures or subtables with one of the following (here
% we assume that two subfigures or subtables appeared in the previous
% pages:
% \begin{quote}
%   |\addtocounter{|\Lcount{subfigure}|}{|2|}|
% \end{quote}
% \vspace{-5pt}
% \noindent
% or
% \vspace{-5pt}
% \begin{quote}
%   |\addtocounter{|\Lcount{subtable}|}{|2|}|.
% \end{quote}
% 
% Two other things that may be necessary, if you switch between figures
% and tables in the same \Lenv{figure} environment ({\it e.g.\/}, by
% changing |\@captype|, see section~\ref{sec:float_env}), is to add the
% command |\listsubcaptions| following the last subfigure when the
% subfigure is using the \Lopt{TOPCAP} or \Lopt{topcap} option.  This is
% necessary to flush the list of subcaptions before the next
% \Lenv{subfigure} or \Lenv{subtable}.  This also may be necessary if
% you switch between |\figuretopcaptrue| and |\figuretopcapfalse|.  The
% other thing that may be required in some cases, is to reset the
% subfigure counter by entering:
% \begin{quote}
%   |\setcounter{|\Lcount{subfigure}|}{|0|}|
% \end{quote}
% \noindent
% This should only be necessary if you are dynamically switching between
% different \Lpack{hhsubfigure} options, or changing the |\@captype|,
% within a float environment.
% 
% \subsection{Modifying the List-of-Figures and List-of-Tables}
% \label{sec:listof}
% 
% To generate a List-of-Figures, or List-of-Tables, page you need to 
% \DescribeMacro{\l@subfigure}
% \DescribeMacro{\@dottedxxxline}
% add a |\listoffigures| or |\listoftables| command where
% you want the list to appear.  These
% commands also cause the appropriate captions and subcaptions to be
% written to a file with the extensions \Lfile{lof} (\Lfile{lot}).  If
% you want the subcaption text to appear in the List-of-Figures or
% List-of-Tables page, you need to change the value of the counter
% \Lcount{lofdepth} (\Lcount{lotdepth}) counter from its default of `1'.
% For example, to have the \Lpack{hhsubfigure} subcaptions to appear on
% the List-of-Figures, add the following to the preamble of your
% paper:
% \begin{quote}
%   |\setcounter{|\Lcount{lofdepth}|}{2}|
% \end{quote}
%
% If you want to change how the subcaption appears on the ``List-of''
% pages you can change its format by redefining the |\l@subfigure|
% or |\l@subtable| command.  Usually you will want to use the
% |\@dottedxxxline| command
% \PrintIfDefined{sec:dl}{(section~\ref{sec:dl},
% page~\pageref{sec:dl})\space}{} to help with the formatting.  For
% instance the default value of |\l@subfigure| is:
%
% \begin{verbatim}
%   \newcommand{\l@subfigure}{%
%     \@dottedxxxline{\ext@subfigure}{2}{3.8em}{2.5em}}
% \end{verbatim}
% \vspace{-10pt}
%
% \noindent
% The arguments of the |\@dottedxxxline| command are:
% \begin{quote}
%   \begin{enumerate}
%     \itemsep -\parsep
%     \item \underline{\smash{\textsf{Type}}}.  The usual values are
%           : \Lfile{lof} or \Lfile{lot}.  The internal
%           values |\ext@subfigure| and |\ext@subtable| stand for
%           these extensions.
%     \item \underline{\textsf{Level}}.  By default this is `2'
%           for the \Lcount{subfigure} and \Lcount{subtable}.  If the level
%           is greater than \Lcount{\meta{Type}depth} (where
%           \underline{\smash{\meta{Type}}} is the first argument, above),
%           then no line is produced.  
%     \item \underline{\textsf{Indent}}.  Total indentation
%           from the left margin. 
%     \item \underline{\textsf{Numwidth}}.  Width of box for the
%           label number if the \underline{\textsf{Title}} has a
%           |\numberline| command.   This is also the amount of extra
%           indentation added to second and later lines of a multiple
%           line entry.    
%     \item \underline{\textsf{Title}}.  Contents of entry ({\it e.g.\/} the
%           \meta{list\_entry} or \meta{subcaption}).
%     \item \underline{\smash{\textsf{Page}}}.  The page number of the
%           figure or table.
%   \end{enumerate}
% \end{quote}
%
% \noindent
% The final two arguments, \underline{\textsf{title}} and
% \underline{\smash{\textsf{page}}}, are automatically appended to the
% value of |\l@subfigure| (and symmetrically for |\l@subtable|).
%
% For example, to change the amount of space reserved for the label 
% (if, for instance, you have a lot of figures and the and you need extra
%  space for the figure number) you could widen the 
% \texttt{2.5em} space for the label to \texttt{4.0em}:
% \begin{verbatim}
%   \makeatletter
%     \renewcommand{\l@subfigure}{%
%       \@dottedxxxline{\ext@subfigure}{2}{3.8em}{4.0em}}
%   \makeatother

% For unbalanced sets of captions placed, above the figures or tables,
% \DescribeMacro{\subfiguretopcaptrue}
% \DescribeMacro{\subfiguretopcapfalse}
% \DescribeMacro{\figuretopcaptrue}
% the caption portion looks unbalanced, such as the ones in 
% figure~\ref{fig:position2}.  If you prefer to have the caption portion
% aligned along the top rather than the bottom, as shown in 
% figure~\ref{fig:position3}, you can use the
% \Lopt{figtopcap} option as in figure~\ref{fig:position2}, but use
% two ``empty'' subfigures to position the captions followed by 
% two more containing the figures, but without captions.  The code
% to produce this example is: 
%
% \begin{verbatim}
%   \begin{figure}%
%   \centering
%     \caption{Caption position option: [\Lopt{figtopcap}] with changing
%              settings of \subfiguretopcap.}%
%     \label{fig:position3}%
%     \subfiguretopcapfalse
%     \subfigure[First caption.]{\hbox to 1.5in{\hfil\null}}%
%     \hspace{0.2in}%
%     \subfigure[Second long, long, long, long, 
%                long, long, long, long caption.]{%
%       \hbox to 1.5in{\hfil\null}}\\[5pt]
%     \subfiguretopcaptrue
%     \subfigure{\fbox{\hbox to 1.5in{\vbox to 15mm{\vfil\null}\hfil}}}%
%     \hspace{0.2in}%
%     \subfigure{\fbox{\hbox to 1.5in{\vbox to 10mm{\vfil\null}\hfil}}}%
%   \end{figure}
% \end{verbatim}
% 
% This example makes use of one of the four flags that control how the
% caption labels are numbered and where the subcaption appears.  Two are
% for |\subfigure| and two for |\subtable|.  The first of each set tell
% the |\subfigure| or |\subtable| command that the related main caption
% appears before or after the set of subfloats.  |\figuretopcaptrue| and
% |\tabletopcaptrue| indicate that the caption appears before and
% |\figureotopcapfalse| and |\tabletopcapfalse| indicate that the it
% appears after.  The other two flags force the subcaption to be placed
% before (|\subfiguretopcaptrue| and |\subtabletopcaptrue|) or after the
% actual subfigure or subtable (|\subfiguretopcapfalse| and
% |\subtabletopcapfalse|).
% 
% There are two difficulties with this approach, first, you need to keep
% changing the setting of |\subfiguretopcap|, and second, if you have
% more than one row of subfigures or subtables, then you will need to
% fiddle with the counter (see section~\ref{sec:counters} to keep the
% numbers straight.  The reason that this format is not supported by the
% \Lpack{hhsubfigure} package is that you need information about all of
% the subfigure or subtables on a row to box the figures correctly and
% this information is not available locally.
% 
% \subsection{Adding Subfloats to New Environments}
% \enlargethispage{15pt}^finalhack
% \label{sec:customfloat}
% 
% It is easy to add a \Lenv{subfloat} command to a new environment.  For
% instance, let us assume we have a new \Lenv{float}
% environment\footnote{For information on creating new float
% environments, see any of the following: \cite{Lamp01}, \cite{Wils01}
% or \cite{Ling01}.} called ``\Lenv{map}'' in which various maps are
% displayed and for which a List-of-Maps is to be generated in the
% contents section.  If we wanted to have \Lenv{submaps}, then we could
% define the following:
% 
% \vspace{-4pt}
% \begin{verbatim}
%   \makeatletter
%     \newcounter{submap}[map]
%     \newif\ifmaptopcap
%     \newif\ifsubmaptopcap
%     \newcommand{\p@submap}{\themap}
%     \newcommand{\thesubmap}{(\alph{submap})}
%     \newcommand{\@thesubmap}{\themap\hskip\subfiglabelskip}
%     \newcommand{\@@thesubmap}{\themap}
%     \newcommand{\ext@submap}{\ext@map}
%     \newcommand{\l@submap}{\@dottedxxxline{\ext@submap}{2}{3.8em}{2.5em}}
%     \newcounter{lomdepth}
%     \setcounter{lomdepth}{1}          
%     \newcommand{\submap}{\subfigure}
%     \newcommand{\@makesubmapcaption}{\@makesubfigurecaption}
%     \ifhyperrefloaded
%       \newcommand\theHsubmap{\themap.\arabic{submap}}
%       \newcommand{\toclevel@submap}{1}
%     \fi
%   \makeatother
% \end{verbatim}
% \vspace{-14pt}
% 
% The first and last lines make the character `@' act like a letter
% between them and therefore it may be part of a command name used there.
% First a new counter for the \Lpack{submap} is created along with two
% conditionals that define where the position ({\i.e.\/}, above or
% below) of the main caption and subcaption is with respect to the
% submap. Then the four commands that define the \Lpack{submap} label
% are created.  The first two, |\p@submap| and |\thesubmap| define the
% standard label returned by |\ref|.  The next, |\@thesubmap| gives the 
% label as shown under or over the submap with the subcaption and the 
% last, |\@@thesubmap| shows how the label is displayed on the List-of-Maps
% and/or referenced with the |\subref| command.
% 
% The next four lines show where and how to print to the List-of-Maps
% page: |\ext@submap| gives the List-of-Maps file extension; |\l@submap|
% shows how to print the submap line on the List-of-Maps page; and the last
% two lines show how to create and set the counter \Lcount{lomdepth}, which
% controls how many caption levels are shown on the page when it is printed.
% 
% The next two lines create the |\submap| and |\@makesubmapcaption|
% commands by making them the same as the |\subfigure| and
% |\@makesubfigurecaption| commands.
% 
% The last four lines conditionally create the |\theHsubmap| and
% |\toclevel@submap| commands which are used by the \Lpack{hyperref}
% Package to name the item and to control the presence of the item
% bookmark.
%
% Of course, this is where the \Lpack{ccaption} package \cite{Wils01}
% comes in handy since it will do all of the above with one command:
%
% \vspace{-4pt}
% \begin{verbatim}
%   \newsubfloat{map}
% \end{verbatim}
% \vspace{-10pt}
%
% 
% \subsection{Interaction with Other Parts of \LaTeX}
% In the following sections, the interaction of the \Lpack{hhsubfigure}
% package with other parts of \LaTeX\ is documented.  These ``other
% parts'' may be either part of the the \LaTeX\ base or contributed
% packages or classes. 
% 
% \subsubsection{\TeX 's ``Mouth''}
% The most important thing to remember when laying out your figures
% within a \Lenv{float} environment is that spaces take room.  If you 
% have an extra space between two figures, then they will be separated 
% by a little bit.
%
% \TeX 's state varies as it reads a line of text from a file.  It
% ignores some spaces and carriage-returns and converts others to
% |\space|'s or |\par|'s.  You can use a `|%|' to insure that you only
% have real spaces where you want them.  To understand which spaces
% are significant, you should read chapters~7 and 8 of the \TeX book
% \cite{Knut86}.  However, the main source of unexpected
% extra spacing is carriage-returns which are turned in to |\space|'s.
% As a general rule: if in doubt, then add a `|%|' immediately after
% the last significant character of the line.
%
% \subsubsection{The Float Environment}
% \label{sec:float_env}
% 
% Although the \Lpack{hhsubfigure} package was designed to work within a
% \Lenv{float} environment ({\it e.g.\/}, \Lenv{figure} or
% \Lenv{table}), it can be used outside with the following two caveats:
% \begin{enumerate}\itemsep=5pt
%   \item You need to define |\@captype|.  This is usually either
%     \Lenv{figure} or \Lenv{table}.  For example add the following
%     to the preamble of your document:
%     \begin{verbatim}
%       \makeatletter
%         \newcommand{\change_cap_type}[1]{%
%           \renewcommand{\@captype}{#1}}
%       \makeatother
%     \end{verbatim}\vspace{-15pt}
%     Then use the new command to switch in the middle of a given
%     \Lenv{float} environment, say from ``figure'' to ``table'' with 
%     the command |\change_cap_type{table}|.
%   \item If you want to define references using |\label|, then you also
%     need to redefine the \LaTeX\ internal |\@currentlabel|.  For
%     example: 
%     \begin{verbatim}
%       \makeatletter
%         \edef\@currentlabel{\p@subfigure\thesubfigure}
%       \makeatother
%     \end{verbatim}\vspace{-15pt}
%     before using the |\label| command.  NOTE: Many other commands change 
%     |\@currentlabel|, including all of the ``section'' commands,
%     |\caption|, \Lenv{equation}'s, and \Lenv{theorem}'s.
% \end{enumerate}
% 
% \subsubsection{Interaction with Other Packages}
%
% \changes{v2.1}{22 Jan 2001}{Added \Lpack{ccaption} reference.}
%
% \changes{v2.1}{11 Oct 1996}{Revised subsubsection on use with
% the caption package and extended this section to talk about the
% \Lpack{captcont} package.} 
%
% \noindent
% The only packages that directly interact with the \Lpack{hhsubfigure}
% package are the \Lpack{caption}/\Lpack{caption2} packages by
% H.A. Sommerfeldt \cite{Somm95a,Somm95b}, the \Lpack{ccaption} package
% and \Lpack{tocloft} packages by Peter Wilson \cite{Wils01,Wils01B},
% and the \Lpack{captcont} package by S.D. Cochran \cite{Coch02}.
% 
% \paragraph{\Lpack{caption}}
% 
% If you load the \Lpack{hhsubfigure} package {\bf before} the
% \Lpack{caption} package, then the \Lpack{caption} package will detect
% that fact and will change the |\subcapsize| when the options
% \Lopt{scriptsize}, \ldots, \Lopt{Large} are specified (overriding such
% options used when loading the \Lpack{hhsubfigure} package).  In
% addition, it redefines |\@thesubfigure| and |\@thesubtable| to use
% |\captionlabelfont|.  It also uses an older layout of
% |\@thesubsubfigure| and |\@thesubtable|.
% 
% The best plan is to load the \Lpack{caption} package {\bf before} the
% \Lpack{hhsubfigure} package.  In addition, you should try to coordinate
% the ``look and feel'' of the two packages.  This limits you a little
% since, although the two packages have similar options, the options in
% the \Lpack{caption} package do not combine the same way.  You can pick
% one from each column:\par\null

% \end{tabular}
% \MakeShortVerb{\|}
% \vskip14pt
% 
% \paragraph{\Lpack{caption2}}
% 
% This package acts similarly to the \Lpack{caption} package.  If you

% package, if you specify \Lopt{nosubfigure} than it will not.  If
% neither option is specified, than load order matters.  If loaded
% {\bf before} the \Lpack{hhsubfigure} package, than it will not try to
% support the package and if loaded {\bf after} it will.
% 
% Again, the best plan is to load the \Lpack{caption2} package 
% {\bf before} the \Lpack{hhsubfigure} package, and specify the
% \Lopt{nosubfigure} option.  In addition, you should try to coordinate
% the ``look and feel'' of the two packages.  This limits you a little
% since, although the two packages have similar options, they are not
% exactly the same; however, most of the good looking combinations are
% easily available.  You can pick one from each column:\par\null

%
% \paragraph{\Lpack{ccaption}}
% 
% The \Lpack{ccaption} package provides for all sorts of extensions and 
% style options for \Lenv{float} |\captions|.  It also provides for the
% use of the |\caption| command outside of a \Lenv{float} environment and
% a mechanism for creating new types of \Lenv{float} environments.
%
% In order to use it with the \Lpack{hhsubfigure} package, you need to 
% pass the \Lopt{subfigure} option when loading it:
% 
% \begin{quote}
%   |\usepackage|[subfigure]\{ccaption\}
% \end{quote}
%
% \paragraph{\Lpack{tocloft}}
% 
% The \Lpack{tocloft} package gives the user the ability to easily
% configure the ``List-of'' pages.  It takes a \Lopt{subfigure} option
% so it doesn't matter which package is loaded first.
%
% \begin{quote}
%   |\usepackage|[subfigure]\{tocloft\}
% \end{quote}
%
% \paragraph{\Lpack{hyperref}}
% \label{sec:hyperref}
%
% \changes{v2.1.2}{26 Mar 2002}{Improved coordination with the hyperref
% package.}
%
% \changes{v2.1.1}{15 Mar 2002}{Added coordination with the hyperref
% package. There is some interaction with the \cmd{label} command as
% pointed out by Martin.Bernreuther@po.uni-stuttgart.de.}
% 
% The \Lpack{hyperref} package extends the functionality of all of the
% \LaTeX\ cross-referencing commands to produce hypertext links.  In
% addition, it provides new commands to allow the user to insert
% hypertext links.  When used with the \Lpack{hhsubfigure} package, they
% may be loaded in any order; however, it might be better if the 
% \Lpack{hhsubfigure} package is loaded {\bf first}.
% 
% To more fully support the \Lpack{hyperref} package, the |\label|
% \DescribeMacro{\subfloat@label}
% command, when used within the scope of the |\subfigure| or |\subtable|
% commands takes an optional argument (note the parentheses rather than
% square brackets):
% \vspace{-2pt}
% \begin{quote}
%   |\label|\parg{bookmark}\marg{key}
% \end{quote}
% \vspace{-2pt}
%
% \noindent
% We would like to use the subcaption as the bookmark text, but the
% |\label| command is often processed before the subcaption.  Therefore,
% this optional argument may be used to supply this information if
% desired.  By default a bookmark field of the form
% ``Subfigure\textvisiblespace 1(a)'' will be generated.
% \footnote{If the document class is \Lpack{report} or other class that
% defines \cmd{\thechapter}, than the default bookmark field will be of the
% form ``Subfigure\textvisiblespace 1 \textvisiblespace 1(a)''.}
% 
% 
% \paragraph{\Lpack{captcont}}
% 
% This package may be used with or without the \Lpack{hhsubfigure} package
% \DescribeMacro{\caption}
% \DescribeMacro{\caption*}
% \DescribeMacro{\captcont}
% \DescribeMacro{\captcont*}
% to extend figure or table numbering across multiple pages.  This
% package knows about how the \Lpack{hhsubfigure} package interacts with
% the List-of-Figures and List-of-Tables and does the right thing when
% used with \Lenv{subfigure}'s and \Lenv{subtable}'s.
% 
% The \Lpack{captcont} package may be loaded either {\bf before} or 
% {\bf after} the \Lpack{hhsubfigure} and it has four options:
% \Lopt{figbotcap} or \Lopt{figtopcap} and \Lopt{tabbotcap} or
% \Lopt{tabtopcap}.  These are the same as the \Lpack{hhsubfigure}
% options.  When the \Lpack{captcont} package is used with the
% \Lpack{hhsubfigure} package, only the \Lpack{hhsubfigure} options matter.
% Any given with the \Lpack{captcont} package are ignored.
% 
% The thing to remember about the \Lpack{captcont} package is that if
% you normally place the |\caption| {\bf before} your subfigures or
% subtables ({\it i.e.\/}, \Lopt{figtopcap} or \Lopt{tabtopcap}
% respectively), then you start a series of continued \Lenv{figure}'s
% with the |\caption[*]| and use |\contcapt[*]| in each of the rest of
% the figures.  If you {\bf follow} your subfigures or subtables with a
% caption ({\it i.e.\/}, \Lopt{figbotcap} or \Lopt{tabbotcap}
% respectively), then you start the series with the |\contcapt[*]| in
% the first \Lenv{figure} environment and all but the last where you use
% the |\caption[*]|.

% figure boxes and place labels under them for a paper that I was
% writing.  I thought it useful and uploaded it to the internet
% community and later to CTAN.  Many people have asked questions or
% given comments which collectively have changed and improved the
% usefulness of this package.
% 
% A few people have contributed more than most and I want to thank
% them publicly, but in no particular order:
% 
% \begin{itemize}\itemsep=-2pt^finalhack
%   \item{\bf Harald Axel Sommerfeldt} for the work that he did to adjust
%     his \Lpack{caption} and \Lpack{caption2} packages as necessary to
%     support the \Lpack{hhsubfigure} package when they are loaded together.
%   \item {\bf Peter Wilson} for the work that he did to adjust his
%     \Lpack{ccaption} package (and other packages) as necessary to support
%     the \Lpack{hhsubfigure} package when they are loaded together.
%   \item {\bf William `bil' L. Kleb} for his extensive list of errors and
%     suggestions to this documentation.
%   \item{\bf Axel Reichert} for his request for a `hang' caption style 
%     since the subcaptions tend to have a short width.  And, for his 
%     request for some way of referencing the individual subfigures in 
%     the main caption without the figure number.
%   \item{\bf Harald Harders} for his suggestion of the \cmd{\subref}
%     command and modifying \cmd{\label} within the \Lpack{hhsubfigure} 
%     package to save local references to the subfigures that are often
%     needed.
%   \item{\bf Heiko Oberdiek} and {\bf James A. Bednar} for their help 
%     with coexisting with the \Lpack{hyperref} and \Lpack{html} packages.
%     Also, {\bf Ingele Roelens} for pointing out some further compatibility
%     problems when using the \Lpack{hyperref} package with PDF\LaTeX.
%   \item{\bf Frederic Darboux} for searching out and finding several
%     incompatibilities with other packages.

% package was among them, if so, then make sure that the |\ifhyperrefloaded|
% switch is set so that the |\subfloat@label| command will write the correct
% form of the |\newlabel| to the \Lfile{aux} file.  Also define the 
% ``TOC level'' of the subfigure and subtable.  We fix these at one since

% 
% These five flags control how the style in which the subfloat label and
% caption are printed.  The \Lif{subcaphang} flag is first checked and
% if true, causes the subcaption label to be typeset separately and
% placed to the upper left of the space available for the subcaption.
% The \Lif{subcapcenter} flag centers each line of the subcaption.  The
% \Lif{subcapcenterlast} centers the last line of the subcaption (this
% is a {\sc nop} if the \Lif{subcapcenter} flag is true.  If the
% \Lif{subcapnooneline} is false, then the label plus the text of the
% subcaption are centered.  If it is true, than the other flags may
% cause something different to happen.  The purpose of this flag,
% generally, is to cause a single line to be left justified when there
% is a very short caption.  The last flag is the \Lif{subcapraggedright}
% which typsets its text without lining up the right side.  This is
% useful for the subcaptions since they are usually short and prone to
% generating hyphenated words unless allowed to be ragged.

% 
% The |\thesubfigure| command defines the label for text references
% (prefixed by |\p@subfigure|).  This is the value saved by the |\label|
% and retrieved by the |\ref| commands.  In the case of a
% conflict between this package and a prior one over the definition
% of |\thesubfigure|, this package will win.  This is insured by first
% specifying the |\providecommand| for the |\thesubfigure| and then
% |\renewcommand|.  This is necessary because some packages incorrectly
% insert this command.
% 
% The |\@thesubfigure| value defines the the caption label complete 
% offset from the beginning of the caption text.  It is used in the
% subfigure caption and normally takes the label portion as defined
% by |\thesubfigure|.
% 
% Finally, the value defined by |\@@thesubfigure| is also saved by the
% |\label| command and may be retrieved with the |\subref| command.  This is
% often useful in the subcaption or caption text when referring to the
% individual subfigures.  This value is also the one that is used in
% the List-of-Figures.
% 
% These multiple ``views'' of the \Lcount{subfigure} counter allow a
% style to define the way the label looks in the figure, for example
% ``{\bf (a)}\textvisiblespace''.  Then references to it with |\ref|
% have the form ``2.1a'', and with |\subref| ``(a)'' (This latter form
% is also used to label references in the List-of-Figures section).

% may be combined with any of the other options (but it's effect is
% negated or looks bad with either of \Lopt{center} or \Lopt{centerlast}
