% many other packages.
% \par\smallskip
% \textit{Please note:} Many document classes already have build-in options and
% commands for customizing captions.
% If these possibilities are sufficient for you, there is usually no need for
% you to use the \package{caption} package at all.
% And if you are only interested in using the command \cs{captionof}, loading of
% the very small \package{capt-of} package is usually sufficient.

% \section*{Introduction}
%
% Within the standard \LaTeX\ document classes captions haven't received the
% attention they deserve. Simply typeset as an ordinary paragraph there is no
% remarkable visual difference from the rest of the text, like here:
%
% \example*{size=normalsize,margin=0pt}{\shortexampletext}
%
% There should be possibilities to change this; for example, it would be nice
% to make the text of the caption a little bit smaller as the normal
% text, add an extra margin, typeset the caption label with the same font
% family and shape as your headings etc. Just like this one:
%
% \example*{size=small,margin=10pt,labelfont=bf,labelsep=endash}{\shortexampletext}
%
% You can do this easily with this package as there are many ready-to-use
% caption formatting options, but you are free to define your very own stuff, too.
%
% \bigskip
%
% \INFO\begin{minipage}[t]{\textwidth}
% \small
% Please note that \thispackage\ is only controlling the look \& feel of the
% captions. It does \emph{not} control the placement of the captions.
% (But you could do so by using other packages like the \package{floatrow}
%  package\cite{floatrow}.)

% \section{Using this package}
% \label{usage}
%
% Insert
% \begin{quote}
%   |\usepackage|\oarg{options}|{caption}[|\texttt{\filedate}|]|
% \end{quote}
% into the preamble of your document, i.e.~the part of your document
% between |\document|\-|class| and |\begin{doc|\-|u|\-|ment}|.
% The options control how your captions will look like; e.g.,
% \begin{quote}
%   |\usepackage[margin=10pt,font=small,labelfont=bf,|\\
%   |            labelsep=endash]{caption}|%
%   %|[|\texttt{\filedate}|]|
% \end{quote}
% would result in captions looking like the second one in the introduction.
%
% \DescribeMacro{\captionsetup}
% For a later change of options \thispackage\ provides the command
% \begin{quote}
%   |\captionsetup|\oarg{float type}\marg{options}\quad.
% \end{quote}
% So
% \begin{quote}
%   |\usepackage[margin=10pt,font=small,labelfont=bf]{caption}|
% \end{quote}
% and
% \begin{quote}
%   |\usepackage{caption}|\\
%   |\captionsetup{margin=10pt,font=small,labelfont=bf}|
% \end{quote}
% are equal in their results.
%
% It's good to know that |\caption|\-|setup| has an effect on the current
% environment only. So if you want to change settings for the
% current |figure| or |table| only, just place the |\caption|\-|setup| command
% inside the |figure| or |table| right before the |\caption| command.
% For example
% \begin{quote}
%   |\begin{figure}|\\
%   |  |\ldots\\
%   |  \captionsetup{singlelinecheck=off}|\\
%   |  \caption{|\ldots|}|\\
%   |\end{figure}|
% \end{quote}
% switches the single-line-check off, but only for this |figure|,
% so all the other captions remain untouched.
%
% \begin{Annotation}
% For a detailed description of |\caption|\-|setup| see \Ref{captionsetup}.
% \end{Annotation}

% \subsection{Formatting}
% \label{formats}
%
% \DescribeMacro{format=}
% A figure or table caption mainly consists of three parts: the caption label,
% which says if this object is a `Figure' or `Table' and what number is
% associated with it, the caption text itself, which is normally a short
% description of contents, and the caption separator which separates the text
% from the label.
%
% The \textit{caption format} determines how this information will be presented;
% it is specified with the option
% \begin{quote}
%   |format=|\meta{format name}\quad,
% \end{quote}
% having the name of the caption format as its argument.
%
% There are two standard caption formats:
% \begin{Options}{\OptionLabel}
%   \item[plain]%\NEWdescription{v3.0h}
%   Typesets the captions as a normal paragraph.
%
%   \item[hang]
%   Indents the caption text, so it will `hang' under the first line of the text.
%
%   \item[\UserDefined]
%   Own formats can be defined using |\Declare|\-|Caption|\-|Format|.\LineBreak
%   \SeeUserDefined
% \end{Options}
%
% \begin{Example}
%   An example: Specifying the option
%   \begin{quote}
%     |format=hang|
%   \end{quote}
%   yields captions like this:
%   \example{format=hang}{\exampletext}
% \end{Example}
%
% \pagebreak[3]
% \DescribeMacro{indention=}
% For both formats (\texttt{plain} and \texttt{hang}) you can setup an extra
% indention starting at the second line of the caption. You do this with the
% option
% \begin{quote}
%   |indention=|\meta{amount}\quad.
% \end{quote}
%
% Two examples:
%
% \begin{Example}
%   \begin{quote}
%     |format=plain,indention=.5cm|
%   \end{quote}
%   \captionsetup{skip=0pt}
%   \example{format=plain,indention=.5cm}{\exampletext}
% \end{Example}
%
% \begin{Example}
%   \begin{quote}
%     |format=hang,indention=-0.5cm|
%   \end{quote}
%   \captionsetup{skip=0pt}
%   \example{format=hang,indention=-0.5cm}{\exampletext}
% \end{Example}
%
% \bigskip
%
% \pagebreak[3]
% \DescribeMacro{labelformat=}
% With the option
% \nopagebreak[3]
% \begin{quote}
%   |labelformat=|\meta{label format name}
% \end{quote}
% \nopagebreak[3]
% you specify how the caption label will be typeset.
% There are five standard caption label formats:
%
% \begin{Options}{\OptionLabel}
%   \item[original]
%   The caption label will be typeset as specified by the document class,
%   usually this means the name and the number (like \texttt{simple}).
%
%   Until \version{3.4} of \thispackage\ this label format was called `default'.
%   Since \version{3.5} it is called `original' and usually is the default label
%   format, so |label|\-|format=|\-|default| will still select this label format,
%   unless the default was changed by either a document class or babel language package.
%
%   \item[empty]
%   The caption label will be empty.
% \iffalse
%   (This option makes sense when used together with other options like
%    \texttt{labelsep=none}.)
% \fi
%
%   \item[simple]
%   The caption label will be typeset as a name and a number.
%
%   \item[brace]\NEWfeature{v3.1f}
%   The caption label will be closed with a single (right) brace.
%
%   \item[parens]
%   The number of the caption label will be typeset in parentheses.
%
%   \item[\UserDefined]
%   Own label formats can be defined using |\Declare|\-|Caption|\-|Label|\-|Format|.
%   \SeeUserDefined
% \end{Options}
%
% \begin{Example}
%   An example: Using the options
%   \begin{quote}
%     |format=plain,labelformat=parens,labelsep=quad|
%   \end{quote}
%   gives captions like this one:
%   \example{format=plain,labelformat=parens,labelsep=quad}{\exampletext}
% \end{Example}
%
% \medskip
%
% \begin{Note*}
% Some environments, e.g.~the |algorithm| environment offered by the
% \package{algorithm2e} package, might react allergic to a change of the
% caption label format.
% \end{Note*}
%
% \bigskip
%
% \pagebreak[3]
% \DescribeMacro{labelsep=}
% With the option
% \begin{quote}
%   |labelsep=|\meta{label separator name}
% \end{quote}
% you specify what caption separator will be used.\footnote{%
%   If the caption label or the caption text is empty,
%   no separator will be used.}
% You can choose one of the following:
%
% \begin{Options}{\OptionLabel}
%   \item[none]
%   There is no caption separator.
% \iffalse
%   (This option makes sense when used together with other options like
%    \texttt{labelformat=empty}.)
% \fi
%
%   \item[colon]
%   The caption label and text will be separated by a colon and a space.
%
%   \item[period]
%   The caption label and text will be separated by a period and a space.
%
%   \item[space]
%   The caption label and text will be separated by a single space.
%
%   \item[quad]
%   The caption label and text will be separated by a |\quad|.
%
%   \item[newline]
%   The caption label and text will be separated by a line break (|\\|).
%   Please note that this separator does not work with all caption
%   formats (e.g.~|format=|\x|hang|), and you'll get an error message
%   trying such combination of options.
%
%   \item[endash]\NEWfeature{v3.0h}
%   The caption label and text will be separated by an en-dash,
%   surrounded by spaces (\verb*| -- |).
%
%   \item[\UserDefined]
%   Own separators can be defined using |\Declare|\-|Caption|\-|Label|\-|Sep|\-|a|\-|ra|\-|tor|.
%   \SeeUserDefined

% \begin{quote}
%   |justification=|\meta{justification name}\quad.
% \end{quote}
%
% You can choose one of the following:
%
% \begin{Options}{\OptionLabel}
%   \item[justified]
%   Typesets the caption as a normal paragraph.
%
%   \item[centering]
%   Each line of the caption will be centered.
%
% \iffalse
%  \item[Centering]
% \fi
%
%   \item[centerlast]
%   The last line of each paragraph of the caption text will be centered.
%
%   \item[centerfirst]
%   Only the first line of the caption will be centered.
%
%   \item[raggedright]
%   Each line of the caption will be moved to the left margin.
%
% \iffalse
%   \item[RaggedRight]
%   Each line of the caption will be moved to the left margin using
%   the command |\RaggedRight| from the \package{ragged2e} package.
% \else
%   \item[RaggedRight]
%   Each line of the caption will be moved to the left margin, too.
%   But this time the command |\RaggedRight| of the \package{ragged2e}
%   package will be used to achieve this.
%   The main difference to |raggedright| is that the word breaking
%   algorithm of \TeX\ will work inside captions.\footnote{%
%     The need for the \package{ragged2e} package will be detected at
%     run-time, therefore you maybe need a second \LaTeX\ run if this
%     option is used for the first time.}
% \fi
%
%   \item[raggedleft]
%   Each line of the caption will be moved to the right margin.
%
% \iffalse
%  \item[RaggedLeft]
%  Each line of the caption will be moved to the right margin using

%   Own justifications can be defined using |\Declare|\-|Caption|\-|Jus|\-|ti|\-|fi|\-|ca|\-|tion|.

%
% \PageBreak
% \DescribeMacro{singlelinecheck=}
% The standard \LaTeX\ document classes (\class{article}, \class{report}, and
% \class{book}) automatically center a caption if it fits in one single line:
%
% \example*{}{A short caption.}
%
% \INFO
% \Thispackage\ adapts this behavior and therefore usually ignores the

% To prevent this you can specify the option |oneside| additionally,

% offered by the \package{wrapfig} package\cite{wrapfig}), the margin setting
% will be automatically reset to |0pt| at the very beginning of the environment.
% But if you really want to setup an extra margin for these environments, you can
% do so by setting this margin either inside the environment itself, of by
% specifying a margin for this particular environment,

%
% \pagebreak[3]
% \DescribeMacro{hangindent=}
% The option
% \begin{quote}
%   |hangindent=|\meta{amount}

% \end{Example}
%
% \begin{Note}

% \subsection{Styles}
% \label{style}
%
% \DescribeMacro{style=}
% A suitable combination of caption options is called \emph{caption style}.
% You can compare them more or less to page styles which you set up with
% |\page|\-|style|;
% the caption style provides all settings for a whole caption layout.
%
% You switch to an already defined caption style with the option
% \begin{quote}
%   |style=|\meta{style name}\quad.
% \end{quote}
% \Thispackage\ pre-defines two styles: |base| and |default|.
%
% \NEWfeature{v3.1}
% The |base| style puts all options you already know about to values reflecting
% the look of the captions when using one of the base \LaTeX\ document classes
% \class{article}, \class{report}, and \class{book}.
% This means that specifying the option
% \begin{quote}
%   |style=base|
% \end{quote}
% has the same effect as specifying all these options:
% \begin{quote}
%   |format=plain,labelformat=default,labelsep=colon,|\\
%   |justification=justified,font={},labelfont={},|\\
%   |textfont={},margin=0pt,indention=0pt|\\
%   |parindent=0pt,hangindent=0pt,singlelinecheck=true|
% \end{quote}
% \begin{Annotation*}
% But |justification=centering,indention=0pt| will be set if
% the caption fits into a single line.
% \end{Annotation*}
%
% In contrast the |default| style follows the default values, reflecting
% the look of the captions given by the document class you actually use.
% This style is selected by default and represents these options:
% \begin{quote}
%   |format=default,labelformat=default,labelsep=default,|\\
%   |justification=default,font=default,labelfont=default,|\\
%   |textfont=default,margin=0pt,indention=0pt|\\
%   |parindent=0pt,hangindent=0pt,singlelinecheck=true|
% \end{quote}
% \begin{Annotation*}
% But again |justification=centering,indention=0pt| will be set if
% the caption fits into a single line.
% \end{Annotation*}
%
% So if you use one of the base \LaTeX\ document classes \class{article},
% \class{report}, or \class{book}, both caption styles, |base| and |default|,
% point to (nearly) the same settings.

% \label{skips}
%
% \DescribeMacro{skip=}
% The vertical space between the caption and the figure or table contents is
% controlled by the option
% \begin{quote}
%   |skip=|\meta{amount}\quad.
% \end{quote}
% The standard \LaTeX\ document classes \class{article}, \class{report} and
% \class{book} preset it to |skip=|\x|10pt|, but other document classes may
% use a different amount.
%
% \bigskip
%
% \pagebreak[3]
% \DescribeMacro{position=}
% The |\caption| command offered by \LaTeX{} has a design flaw:
% The command does not know if it stands on the beginning of the figure or
% table, or at the end. Therefore it does not know where to put the space
% separating the caption from the content of the figure or table.
% While the standard implementation always puts the space above the caption
% in floating environments (and inconsistently below the caption in
% |long|\-|table|s), the implementation offered by this package is more
% flexible:
% By giving the option
% \begin{quote}
%   |position=top|\quad or\quad |position=above|
% \end{quote}
% it's assumed that the caption is standing at the \emph{top} of the
% environment and therefore the space setup with |skip=|\x\meta{amount}
% is placed below the caption.
% (Please note that |position=|\x|top| does \emph{NOT} mean that the
% caption is actually placed at the top of the figure or table.
% Instead the caption is usually placed where you place the |\caption|
% command.)
% But with
% \begin{quote}
%   |position=bottom|\quad or\quad |position=below|
% \end{quote}
% it's assumed that the caption is standing at the \emph{bottom} of the
% environment and therefore the space is placed above the caption.
% And finally with
% \begin{quote}
%   |position=auto|\quad {\small(which is the default setting)}
% \end{quote}
% \thispackage\ tries its best to determine the actual position of
% the caption on its own. Please note that while this is successfully in
% most cases, it could give wrong results under rare circumstances.
%
% \medskip
%
% \pagebreak[3]
% \DescribeMacro{figureposition=}
% \DescribeMacro{tableposition=}
% The |position| option is especially useful when used together with the
% optional argument of the |\caption|\-|setup| command.
% \See{also \Ref{captionsetup}}\par
% For example
% \begin{quote}
%   |\captionsetup[table]{position=above}|
% \end{quote}
% causes all captions within tables to be treated as captions \emph{above}
% the table (regarding spacing around it).
% Because this is a very common setting, \thispackage\ offers
% the abbreviating options |figure|\-|position=|\x\meta{pos} and
% |table|\-|position=|\x\meta{pos}, e.g.
% \begin{quote}
%   |\usepackage[|\ldots|,tableposition=top]{caption}|
% \end{quote}
% is equivalent to
% \begin{quote}
%   |\usepackage[|\ldots|]{caption}|\\
%   |\captionsetup[table]{position=top}|
% \end{quote}
%
% \medskip
%
% \INFO
% Please note that the options |skip=|, |position=|, |figure|\-|position=|,
% and |table|\-|position=| do not always have an effect.
% Since it's a matter of the document class to supply the environments
% |figure| and |table|, it could use its very own spacing, and could
% decide for itself if the caption will be typeset as ``top'' or ``bottom''
% caption.
% For example the \KOMAScript\ document classes support the |skip=|
% setting, but will always typeset |figure| captions as ``bottom'' captions,
% and |table| captions are dependent on the global option
% |table|\-|captions|\-|above| resp.\ |table|\-|captions|\-|below|.
% \See{\Ref{KOMA}}
%
% Furthermore some packages control the behavior of the spacing above and
% below the caption for themself, e.g.~the \package{float}, the
% \package{floatrow}, and the \package{supertabular} package.
%
% \bigskip
%
% \begin{Expert*}
% Internally the skip between caption and contents is represented by
% |\above|\-|caption|\-|skip| (which is always set above the caption in
% \LaTeX{}s implementation).
% But there is a second value |\below|\-|caption|\-|skip| (usually set to
% |0pt| by default) which is set below the caption in \LaTeX{}s implementation,
% but on the other side than |\above|\-|caption|\-|skip| by this package.
% So technically speaking, this package swaps the meaning of these two skips
% when |position=|\x|top| is set.
% Please note that there are several packages around which do the same trick
% (like the \package{ftcap}, the \package{nonfloat}, and the \package{topcap}
% package), so the usage of the \package{caption} option |position=| is not
% supported if one of these packages will be used, too.

% if no \meta{list entry} has been given. But if a \meta{list entry} is given,
% this argument is moving instead.
% ``\emph{Moving} argument'' means that the argument will be written to the
% list-of file, make it appearing in the ``List of Figures'' resp.
% ``List of Tables'', too.
% \emph{Moving} arguments are not allowed to contain \emph{fragile} commands,
% everything must be \emph{robust}, otherwise the argument could get
% \emph{broken}, resulting in strange errors at the next \LaTeX\ run.
% Some \emph{fragile} commands could be \emph{protected} by a leading |\protect|,
% own definitions could get defined with |\Declare|\-|Robust|\-|Command| instead of
% |\new|\-|command| to make them \emph{robust}.
%
% An example: |\caption{${}^{137}_{\phantom{1}55}$Cs}| will cause errors since
% |\phantom| is \emph{fragile}.
% So we have either have to use the optional argument \meta{list entry}
% (e.g.~|\caption[${}^|\x|{137}_|\x|{55}$|\x|Cs]|\x|{${}^|\x|{137}_|\x|{\phantom{1}55}$|\x|Cs}|)
% or add |\protect| to prevent the |\phantom| command from getting \emph{broken}:
% |\caption{${}^|\x|{137}_|\x|{|\textcolor{blue}{\cs{protect}}|\phantom{1}55}$|\x|Cs}|.
%
% But sometimes even this is not sufficient. The reason behind is the so-called
% single-line-check: It puts the \meta{heading} into a horizontal box to determine
% the width of the caption, and this could cause error messages, too.
% An example:
% |\caption{A| |scheme.| |\[V_{C}| |\sim| |\left| |\{| |\begin{array}{cc}|
% |E_{g}| |&| |\textrm{p-n}| |\\| |e\phi_{B}| |&| |\textrm{M-S}| |\end{array}|
% |\right.| |\]}|.
% Using |\caption[A| |scheme]{|\ldots|}| is not sufficient here, it's still
% leading to errors. (``\texttt{Missing \$ inserted.}'')
% So we have to put a |\caption|\-|setup{single|\-|line|\-|check=|\x|off}|
% just in front of the |\caption| command additionally.
%
% For more information about \emph{moving} arguments and \emph{fragile} \&
% \emph{robust} commands, take a closer look at your \LaTeX\ manual or visit
% \url{http://www-h.eng.cam.ac.uk/help/tpl/textprocessing/teTeX/latex/latex2e-html/fragile.html}.

% The \package{longtable} package defines the command |\caption*| which
% typesets the caption without label and without entry in the list of tables.
% An example:
% \begin{quote}
%   |\begin{longtable}{|\ldots|}|\\
%   |  \caption*{A table}\\|\\
%   |  |\ldots\\
%   |\end{longtable}|
% \end{quote}
% looks like

% \vskip\intextsep
% \begin{minipage}{\linewidth}
%   \captionsetup{type=table,position=t}
%   \caption*{A table}

% \MakeShortVerb{\|}
% \Thispackage\ offers this feature, too, so you can use this command now within
% every floating environment like |figure| or |table|, like:
% \begin{quote}

% \DescribeMacro{\captionof}
% \DescribeMacro{\captionof*}
% Sometimes you want to typeset a caption \emph{outside} a floating environment,
% putting a figure within a non-floating |mini|\-|page| for instance.
% For this purpose \thispackage\ offers the command
% \begin{quote}
%   |\captionof|\marg{float type}\oarg{list entry}\marg{heading}\quad.
% \end{quote}
% Note that the first argument, the \meta{float type}, is mandatory here, because
% the |\captionof| command needs to know which name to put into the caption label
% (e.g. ``Figure'' or ``Table'') and in which list to put the contents entry.
% An example:
% \begin{quote}
%   |\captionof{table}{A table}|
% \end{quote}
% typesets captions like this:
% \begin{Example}
%   \captionsetup{position=top}
%   \captionof{table}{A table}
% \end{Example}
%
% The star variant |\caption|\-|of*| has the same behavior as the |\caption*|
% command:
% It typesets the caption without label and without entry to the list of figures
% or tables.
%
% \INFO % \NEWdescription{v3.1}
% Since |\caption|\-|of| uses the option |type| internally, the same
% restrictions as for the |type| option apply here, so you should use both
% |\caption|\-|of| and |\caption|\-|of*| only \emph{inside} boxes or

% This could be achieved with
% \begin{quote}
%   |\captionlistentry|\oarg{float type}\marg{list entry}\quad.
% \end{quote}
%
% One example: It's quite easy to have a |long|\-|table| with captions above the
% contents and a single list entry which points to the first page of the table:
% \begin{quote}
%   |\begin{longtable}{|\ldots|}|\\

%   |\endfirsthead|\\
%   |  \caption[]{|\ldots|}\\|\\
%   |\endhead|\\

% But since the \package{longtable} package does not offer an
% |\end|\-|first|\-|foot| command, you cannot easily have captions \emph{below}
% the table contents and a single list entry which points to the first page of
% the table.
% Here is were the |\caption|\-|list|\-|entry| command could be used:
% \begin{quote}
%   |\begin{longtable}{|\ldots|}|\\
%   |  \caption[]{|\ldots|}\\|\\
%   |\endfoot|\\

% \begin{Expert}
% There is also a starred variant, |\caption|\-|list|\-|entry*|, which does not
% increment the \meta{float type} counter.

% never increments the |table| counter. See also \Ref{longtable}.)

% \subsection{Setting options}
% \label{captionsetup}
%
% \DescribeMacro{\captionsetup}
% We already know the |\caption|\-|setup| command (see \Ref{usage}),
% but this time we get enlighten about its optional argument
% \meta{float type}.
%
% Remember, the syntax of this command is
% \begin{quote}
%   |\captionsetup|\oarg{float type}\marg{options}\quad.
% \end{quote}
% If a \meta{float type} gets specified, all the \meta{options} don't
% change anything at this time. Instead they only get marked for a later use,
% when a caption inside of a floating environment of the particular type
% \meta{float type} gets typeset.
% For example
% \begin{quote}
%   |\captionsetup[figure]|\marg{options}
% \end{quote}
% forces captions within a |figure| environment to use the given \meta{options}.
%
% Here comes an example to illustrate this:
% \begin{quote}
%   |\captionsetup{font=small}|\\
%   |\captionsetup[figure]{labelfont=bf,textfont=it}|
% \end{quote}
% gives captions like this:
% \begin{Example}
%   \captionsetup{font=small}
%   \captionsetup[figure]{labelfont=bf,textfont=it}
%   \begingroup
%     \captionof{figure}{A figure}
%   \endgroup
%   \captionsetup{position=top}
%   \begingroup
%     \captionof{table}{A table}
%   \endgroup
% \end{Example}
% As you see the command |\caption|\-|setup[figure]{|\ldots|}| only changes
% the look of the |figure| caption labels, not touching the other ones.
%
% As \meta{float type} you can usually give one of these two only:
% |figure| or |table|.
% But as we will see later some \LaTeX\ packages (like the \package{floatrow},
% \package{longtable}, and \package{sidecap} package for example) and also
% this package offer additional environments with captions and these two
% commands can also be used with them.
% \See{\Ref{declare} and \Ref{packages}}
%
% \begin{Expert}
% \NEWfeature{v3.1}
% There is also a starred variant of |\caption|\-|setup|:
% \begin{quote}
%   |\captionsetup*|\oarg{float type}\marg{options}
% \end{quote}
% While the non-starred variant can give you warnings---for example if the
% \meta{options} are actually not used throughout the document
% (e.g.~a |\caption|\-|setup[table]{font=|\x|sf}| without a |table|)---the
% starred variant will not.

% \subsection{Continued floats}
% \label{ContinuedFloat}
%
% \DescribeMacro{\ContinuedFloat}
% Sometimes you want to split figures or tables without giving them
% their own reference number. This is what the command
% \begin{quote}
%   |\ContinuedFloat|
% \end{quote}
% is for; it should be used as first command inside the floating environment.
% It prevents the incrementation of the relevant counter (usually done by
% |\caption|), so a figure or table containing a |\Continued|\-|Float| inside
% gets the same reference number as the figure or table before.
% An example:
% \begin{quote}
%   |\begin{table}|\\
%   |  \caption{A table}|\\
%   |  |\ldots\\
%   |\end{table}|\\
%   \ldots\\
%   |\begin{table}\ContinuedFloat|\\
%   |  \caption{A table (cont.)}|\\
%   |  |\ldots\\
%   |\end{table}|
% \end{quote}
% gives the following result:
% \begin{Example}
%   \captionsetup{type=table,position=b,skip=0pt}
%   \caption{A table}
%   \centerline{\ldots}
% \end{Example}
% \begin{Example}
%   \captionsetup{type=table,position=b,skip=0pt}
%   \ContinuedFloat
%   \caption{A table (cont.)}
%   \centerline{\ldots}
% \end{Example}
%
% \bigskip
%
% \NEWfeature{v3.1}
% Furthermore the |\Continued|\-|Float| command executes options associated with
% the type name ``|Continued|\-|Float|''. For example this can be used to switch
% to a different label format for continued figures or tables, as shown here:
% \begin{quote}
%   |\DeclareCaptionLabelFormat{continued}{Continued #1~#2}|\\
%   |\captionsetup[ContinuedFloat]{labelformat=continued}|\\
%   \ldots\\
%   |\begin{table}\ContinuedFloat|\\
%   |  \caption{A table}|\\
%   |  |\ldots\\
%   |\end{table}|
% \end{quote}
% \begin{Example}
%   \captionsetup{type=table,position=b,skip=0pt}
%   \captionsetup[ContinuedFloat]{labelformat=continued1}
%   \ContinuedFloat
%   \caption{A table}\label{continued1}
%   \centerline{\ldots}
% \end{Example}
% \smallskip
% \See{\Ref{declare} for an explanation of
%      \cs{Declare}\-\texttt{Caption}\-\texttt{Label}\-\texttt{Format}.}
%
% \medskip
%
% There is also a \LaTeX\ counter called |Continued|\-|Float| which could be
% used for own purposes.
% For ordinary (floating) environments it's set to zero, to one for the first
% continued float, to two inside the second one, and so on.
% So every |\Continued|\-|Float| increments this counter and a floating
% environment without |\Continued|\-|Float| command resets this counter to zero.
% An example:
% \begin{quote}
%   |\DeclareCaptionLabelFormat{cont}{#1~#2\alph{ContinuedFloat}}|\\
%   |\captionsetup[ContinuedFloat]{labelformat=cont}|\\
%   \ldots\\
%   |\begin{table}\ContinuedFloat|\\
%   |  \caption{A table}|\\
%   |  |\ldots\\
%   |\end{table}|
% \end{quote}
% \begin{Example}
%   \captionsetup{type=table,position=b,skip=0pt}
%   \captionsetup[ContinuedFloat]{labelformat=continued2}
%   \ContinuedFloat
%   \caption{A table}\label{continued2}
%   \centerline{\ldots}
% \end{Example}
% \medskip
% A reference to this table would still result in the output
% ``\autoref{continued2}'' since only the caption label format was changed.
% If you would like to use the |Continued|\-|Float| counter for the references,
% too, you could redefine the command |\the|\-|Continued|\-|Float| instead,
% which will be appended to the figure or table counter automatically in
% continued floats and is preset to be empty.
% \begin{quote}
%   |\renewcommand\theContinuedFloat{\alph{ContinuedFloat}}|\\
%   \ldots\\
%   |\begin{table}\ContinuedFloat|\\
%   |  \caption{A table}|\\
%   |  |\ldots\\

% \begin{Example}
%   \captionsetup{type=table,position=b,skip=0pt}
%   \renewcommand\theContinuedFloat{\alph{ContinuedFloat}}
%   \ContinuedFloat
%   \caption{A table}\label{continued3}
%   \centerline{\ldots}
% \end{Example}
% \medskip
% A reference to that table would result in the output ``\autoref{continued3}''.

% \begin{quote}
%   |\DeclareCaptionFormat{plain}{#1#2#3\par}|\quad.

% \end{quote}
% At usage \#1 gets replaced with the name (e.g. ``figure'') and \#2
% gets replaced with the reference number (e.g. ``12'').
% An example:

% You can define your own caption styles with
% \begin{quote}
%   |\DeclareCaptionStyle|\marg{name}\oarg{additional options}\marg{options}\mbox{\quad.}
% \end{quote}
% Remember, caption styles are just a collection of suitable options, saved
% under a given name. You can wake up these options at any time with the
% option |style=|\meta{style name}.
%
% All caption styles are based on the |base| set of options. (See \Ref{style}
% for a complete list.) So you only need to specify options which are different
% to them.
%
% If you specify \meta{additional options} they get used in addition when
% the caption fits into a single line and this check was not disabled with
% the option |single|\-|line|\-|check=off|.
%
% Again a very easy example taken from the core of this package: The
% caption style |base| is pre-defined as
% \begin{quote}
%   |\DeclareCaptionStyle{base}%|\\
%   |        [justification=centering,indention=0pt]{}|\quad.
% \end{quote}

%   |        {font=footnotesize,labelfont=sc,margin={10mm,0mm}}|\\
%   |\captionsetup{style=mystyle}|

% \subsection{Further examples}
% \label{examples}
%
% \subsubsection*{Example 1}
%
% If you would like to have a line break between caption label and text
% you could define it this way:
% \begin{quote}
%   |\DeclareCaptionFormat{myformat}{#1#2\\#3}|
% \end{quote}
% If you select this format with |\caption|\-|setup{format=|\x|myformat}|
% you get captions like this:
%   \example{format=myformat1,labelfont=bf}{\exampletext}
% You could even use an indention with this caption format:
% \begin{quote}
%   |\captionsetup{format=myformat,indention=1cm}|
% \end{quote}
% This would look like this:
%   \example{format=myformat1,indention=1cm,labelfont=bf}{\exampletext}
% Instead, you would like to have an indention only of the first line of
% the caption text? No problem, e.g.
% \begin{quote}
%   |\newlength\myindention|\\
%   |\DeclareCaptionFormat{myformat}%|\\
%   |               {#1#2\\\hspace*{\myindention}#3}|\\
%   \ldots\\
%   |\setlength\myindention{1cm}|\\
%   |\captionsetup{format=myformat}|
% \end{quote}
% would give you captions like
%   \example{format=myformat2,myindention=1cm,labelfont=bf}{\exampletext}
% But you want to have an caption option for this indention, so you can use
% it for example with
% |\caption|\-|setup|\x|[figure]|\x|{my|\-|indention=|\x\ldots|}|?
% This could be done, too:
% \begin{quote}
%   |\newlength\myindention|\\
%   |\DeclareCaptionOption{myindention}%|\\
%   |               {\setlength\myindention{#1}}|\\
%   |\DeclareCaptionFormat{myformat}%|\\
%   |               {#1#2\\\hspace*{\myindention} #3}|\\
%   \ldots\\
%   |\captionsetup{format=myformat,myindention=1cm}|
% \end{quote}
% would give the same result as the example above.
%
% \subsubsection*{Example 2}
%
% You want captions to look like this:
%   \example{format=reverse,labelformat=fullparens,labelsep=fill,labelfont=it}{\exampletext}
%
% \pagebreak[2]
% You could do it this way:
% \nopagebreak[3]
% \begin{quote}
%   |\DeclareCaptionFormat{reverse}{#3#2#1}|\\
%   |\DeclareCaptionLabelFormat{fullparens}%|\\
%   |               {(\bothIfFirst{#1}{~}#2)}|\\
%   |\DeclareCaptionLabelSeparator{fill}{\hfill}|\\
%   |\captionsetup{format=reverse,labelformat=fullparens,|\\
%   |              labelsep=fill,font=small,labelfont=it}|
% \end{quote}
%
% \subsubsection*{Example 3}
%
% The caption text should go into the left margin? A possible solution would be:
% \begin{quote}
%   |\DeclareCaptionFormat{llap}{\llap{#1#2}#3\par}|\\
%   |\captionsetup{format=llap,labelsep=quad,singlelinecheck=no}|
% \end{quote}
% As a result you would get captions like this:
% \example{format=llap,labelsep=quad,singlelinecheck=no,margin=0pt}{\exampletext}
%
% \medskip
%
% If the indention into the margin shall be fixed, you could use a combination
% of |\llap| and |\makebox|, for example:
% \begin{quote}
%   |\DeclareCaptionFormat{llapx}%|\\
%   |               {\llap{\makebox[5em][l]{#1}}#3\par}|\\
%   |\captionsetup{format=llapx,singlelinecheck=off}|
% \end{quote}
% \example{format=llapx,singlelinecheck=off,skip=0pt,margin=0pt}{\exampletext}
%
% \subsubsection*{Example 4}
%
% This example puts a figure aside a table, but uses only one common caption for both.
% This will be achieved by a combination of
% |\Declare|\-|Caption|\-|Label|\-|Format| and |\caption|\-|list|\-|entry|:
% \begin{quote}

% \section{Supported document classes}
% \label{classes}
%
% This section will give you an overview of the document classes the
% \package{caption} supports, what do they already offer regarding captions,
% what side effects will occur when using the \package{caption} package with
% them, and what are the `default' settings for them.
%
% \NEWfeature{v3.1}
% The `default' settings depend on the document class you use; they represent
% how the class author wanted the captions to look like. So for example
% setting |format=|\x|default| can give you different visual designs when used
% with different document classes.
%
% \begingroup\setlength\leftmargini{0.3em}% default = 2.5em
% \INFO
% If you don't find the document class you use in this section, you usually
% don't have to worry: Many document classes (e.g.~the \class{octavo} class)
% are derived from one of the standard document classes \class{article},
% \class{report}, or \class{book}, and behave the same regarding captions.
% \Thispackage\ automatically does a compatibility check against the document
% class used and will give you the clear warning
% \begin{quote}\footnotesize
%   |Package caption Warning: Unsupported document class (or package) detected,|\\
%   |(caption)                usage of the caption package is not recommended.|\\
%   |See the caption package documentation for explanation.|
% \end{quote}
% if such an incompatibility was detected.
% If you don't get such warning everything is fine, but if you get it the
% usage of \thispackage\ is not recommended and especially not supported.
% \endgroup
%
% \begin{Expert}
% If you get such a compatibility warning but decide to use \thispackage{}
% anyway, you should watch carefully what side-effects occur, usually the
% look and feel of your captions will change by just including \thispackage{}
% without options, meaning they do not look like as intended by the author
% of the document class.
% If this is fine for you, you should first specify the option |style=|\x|base|
% via |\use|\-|package[style=|\x|base]{caption}| or
% |\caption|\-|setup{style=|\x|base}| to set \thispackage\ into a well-defined
% state.
% Afterwards you can start setting your own options additionally and

% \packagedescription{%
% The \package{algorithm2e} package\cite{algorithm2e} offers an environment for
% writing algorithms in LaTeX2e.}
%
% Since the \package{algorithm2e} package does not use some kind of standard
% interface for defining its floating environment (e.g.~|\newfloat| of the
% \package{float} package) and typesetting its caption,
% the \package{algorithm2e} package is \emph{not} supported by \thispackage.
%
% So if you want to customize the captions using \thispackage,
% you have to build a new environment which uses a supported interface regarding
% floats (e.g. using the \package{float} or \package{floatrow} package),
% and combine this environment with the internal \package{algorithm2e} code.
%
% As first step you could define a non-floating environment \texttt{algorithmic},
% for example:
% \begin{quote}
%   |\usepackage{algorithm2e}|\\
%   |% save the "algorithm" environment from the algorithm2e package|\\
%   |\let\ORIGalgorithm\algorithm|\\
%   |\let\ORIGendalgorithm\endalgorithm|\\

%   |\newenvironment{algorithmic}%|\\
%   |  {\renewenvironment{algocf}[1][h]{}{}% pass over floating stuff|\\
%   |   \ORIGalgorithm}%|\\
%   |  {\ORIGendalgorithm}|\\
%   \ldots
% \end{quote}
% Having defined this non-floating environment, you could define your own new
% floating environment with |\newfloat| of the \package{float} package
% (or |\DeclareNewFloatType| of the \package{floatrow} package),
% and use the combination of this floating environment and \texttt{algorithmic}
% in its body, just like you would do when you use the
% \package{algorithm}/\package{algorithmic} package tandem.
%
% You could even use the \package{algorithm} package for this purpose, for example:
% \begin{quote}
%   \ldots\\
%   |% load the algorithm package to re-define the|\\
%   |% floating environment "algorithm" and \listofalgorithms|\\
%   |\let\listofalgorithms\undefined|\\

% \packagedescription{%
% The \package{float} package\cite{float} introduces the commands
% \cs{restylefloat} to give existing floating environments a new look \& feel
% and \cs{newfloat} to define new floating environments.
% It also provides the ``\texttt{H}'' float placement option which places
% the environments ``here'' instead of letting them floating around.}
%
% For floating environments defined with \cs{newfloat} or \cs{restylefloat} the
% |po|\-|si|\-|tion| option has no effect on the main caption anymore, since its
% placement and spacing will be controlled by the selected float style instead.
%
% A caption style and options defined with the name of the float style will be
% executed additionally to the regular ones.
% Using this mechanism \thispackage\ emulates the default look \& feel of the
% |ruled| captions: It defines the caption style
% \begin{quote}
%   |\DeclareCaptionStyle{ruled}%|\\
%   |       {labelfont=bf,labelsep=space,strut=off}|\mbox{\quad.}
% \end{quote}
% So to change this you need either define your own caption style called
% |ruled| or use |\caption|\-|setup[ruled]|\marg{options} to specify additional
% options.
%
% Also by using this mechanism the skip between a |boxed| float and its caption
% is specified, overriding its global value:
% \begin{quote}
%   |\captionsetup[boxed]{skip=2pt}|
% \end{quote}
% For changing this, just use |\caption|\-|setup[boxed]{skip=|\x\meta{value}|}|
% with an appropriate value. Or if you want to use the global |skip| setting
% instead, you can remove the usage of the local setting for these floats with
% |\clear|\-|caption|\-|setup[skip]{boxed}|.
%
% \begin{Note}
% Only one single caption can be typeset inside environments defined with
% |\new|\-|float| or |\re|\-|style|\-|float|, furthermore these environments
% are not behaving exactly like the pre-defined floats |figure| and |table|.
% As a consequence many packages do not cooperate well with these.
% Furthermore the \package{float} package has some caveats \& limitations,
% so if you just want to define a new simple floating environment---behaving
% like |figure| or |table|---I recommend using |\Declare|\-|Floating|\-|Environment|
% offered by the \package{newfloat} package instead.
% And for defining non-simple floating environments and customization I
% recommend using |\Declare|\-|New|\-|Float|\-|Type| offered by the
% \package{floatrow} package\cite{floatrow}.

% Without \package{hyperref} loaded, both will give you identical results.

% |\begin{minipage}{\linewidth}|\\
% |  \captionsetup{type=figure}|\\
% |  |\ldots\\
% |  \caption{A figure}|\\
% |\end{minipage}|
% \end{quote}

% So for example the optional argument of |\caption| will also be written to

% So if you choose to use |\caption| with empty optional argument,
% |\name|\-|ref| will also give you an empty result.

% want an entry in the List of Figures or List of Tables.

% \Description
%   If \thispackage\ detects that some (unknown) document class or

%   As a result some features, like |\caption*|, |\Continued|\-|Float|,

% \Description
%   Regarding |\label| the floating environments behave differently than its

%   and this option can not be found inside the option list, you will

%   |The option `hypcap=true' will be ignored for this|\\

% \Description
%   \Thispackage\ hasn't found a proper hyperlink anchor for this particular
%   caption, so it decides to ignore the setting |hypcap=|\x|true| (which is set by
%   default). As a result a link to this caption (e.g.~in the List of Figures,
%   or set by |\ref| or |\auto|\-|ref|) will link you to the caption of the figure
%   or table, not to the figure or table itself.\par
%   This can happen if you use |\caption|\-|of| inside a non-floating environment,
%   but also if you use some package which redefines |figure| or |table|, and
%   which is unknown to \thispackage.\par
%   If this is ok for you but you want to suppress this warning, simply place a
%   |\caption|\-|setup{hyp|\-|cap=|\x|false}| just before the |\caption| or
%   |\caption|\-|of| command which is causing the warning.
%   If this is not ok for you, you can set a hyperlink anchor with
%   |\caption|\-|setup{type=|\x\meta{float type}|}| for yourself.

%   which is unknown to \thispackage, or simply because you don't have any usage
%   of the environment \meta{type} after this line.

% \section{Version history}
% \label{history}
%
% The version $1.0$ was written in 1994 and was offering a handful of options
% to customize the look \& feel of the captions.
% Furthermore this version already supported the \package{rotating} and
% \package{subfigure} packages.
% Version $1.1$ introduced the |center|\-|last| option;
% version $1.2$ added the support of the \package{float} package.
% Version $1,3$ offered a better support of the \package{subfigure} package,
% while version $1.4$ came with the new option |nooneline|.
%
% The \package{caption2} package $2.0$ was an experimental side-version of
% the regular \package{caption} package. It was made public as beta test version
% without proper documentation in 1995 because of the strong demand for new
% features and adaptations to additional packages like the \package{longtable}
% package.
% Furthermore it offered a revised support of the \package{subfigure} package.
% (An improved version $2.1$ was offered in 2002.)
%
% In 2003 I finally found some time, so a new regular release $3.0$
% of the \package{caption} package could be build in cooperation with
% Frank Mittelbach and Steven Cochran.
% It was released in December 2003 and superseded the neglected
% \package{caption2} package.
% Main parts were re-written and it provided a complete re-work of
% the user interface.
% Furthermore it supported the \package{hyperref}, \package{hypcap},
% \package{listings}, \package{sidecap}, and \package{supertabular} packages
% additionally.
%
% While all the previous versions were designed for usage with the standard
% \LaTeX\ document classes \class{article}, \class{report}, and \class{book},
% the current version $3.1$ released in 2007 also supports the \AmS,
% \KOMAScript, \NTG, and \SmF\ document classes, and the \class{beamer} class
% as well.
% Furthermore it was adapted to the \package{french} Babel option,
% the \package{frenchle} \& \package{frenchpro} packages,
% and the \package{floatflt}, \package{fltpage}, \package{picinpar},
% \package{picins}, \package{setspace}, \package{threeparttable},
% and \package{wrapfig} packages.
% New options and commands were introduced as well, among other things
% |font+|, |figure|\-|within| \& |table|\-|within|,
% |list| \& |list|\-|format|, |max|\-|margin| \& |min|\-|margin|,
% |\caption|\-|list|\-|entry|, |\Declare|\-|Caption|\-|List|\-|Format|.
% Further benefits are the new compatibility check \see*{\Ref{compatibility}},
% the new ``hypcap'' feature \see*{\Ref{hyperref}\,}, and the sub-caption
% feature \see*{\package{subcaption} package documentation}.

% \section{Compatibility to older versions}
%
% \subsection{caption v\texorpdfstring{$1.x$}{1.x}}
% \label{caption1}
%
% This version of \thispackage\ still supports the old options
% and commands provided by the version $1.0$ to $1.4$ of this package.
% So there shouldn't occur any problems compiling old documents, but please
% don't mix old options and commands with the new ones. This isn't supported
% and can cause ugly side effects.
%
% Here comes a short oversight of the obsolete options and how
% they have been replaced within this version of \thispackage:
%
% \begin{center}\small
% \begin{tabular}{ll}
% \package{caption} \version{1.x} & \package{caption} \version{3.x}\\
% \hline
% |normal|        & |format=plain|\\
% |hang|          & |format=hang|\\
% |isu|           & |format=hang|\\
% |center|        & |justification=centering|\\
% |centerlast|    & |justification=centerlast|\\
% |nooneline|     & |singlelinecheck=off|\\
% |scriptsize|    & |font=scriptsize|\\
% |footnotesize|  & |font=footnotesize|\\
% |small|         & |font=small|\\
% |normalsize|    & |font=normalsize|\\
% |large|         & |font=large|\\
% |Large|         & |font=Large|\\
% |up|            & |labelfont=up|\\
% |it|            & |labelfont=it|\\
% |sl|            & |labelfont=sl|\\
% |sc|            & |labelfont=sc|\\
% |md|            & |labelfont=md|\\
% |bf|            & |labelfont=bf|\\
% |rm|            & |labelfont=rm|\\
% |sf|            & |labelfont=sf|\\
% |tt|            & |labelfont=tt|\\
% \end{tabular}
% \end{center}
%
% Beside the options for setting up the desired font there were also
% the commands |\caption|\-|size| resp.~|\caption|\-|font| and
% |\caption|\-|label|\-|font| who could be redefined with
% |\re|\-|new|\-|command| and allowed an alternate and more flexible way to
% change the font used for captions.
% This mechanism was replaced by the commands
% \begin{quote}
%   |\DeclareCaptionFont{|\ldots|}{|\ldots|}|\qquad and\\
%   |\captionsetup{font=|\ldots|,labelfont=|\ldots|}|\qquad.
% \end{quote}
% \SeeUserDefined
%
% Setting the margin for captions was done in \version{1.x} with
% \begin{quote}
%   |\setlength{\captionmargin}{|\ldots|}|\quad.
% \end{quote}
% This was replaced by
% \begin{quote}
%   |\captionsetup{margin=|\ldots|}|\qquad.
% \end{quote}
% \See{\Ref{margins}}
%
% For example the old-style code
% \begin{quote}
%   |\usepackage[hang,bf]{caption}|\\
%   |\renewcommand\captionfont{\small\sffamily}|\\
%   |\setlength\captionmargin{10pt}|
% \end{quote}
% will still work fine, but should be written today as
% \begin{quote}
%   |\usepackage[format=hang,labelfont=bf,font={small,sf},|\\
%   |            margin=10pt]{caption}|
% \end{quote}
% or
% \begin{quote}
%   |\usepackage{caption}|\\
%   |\captionsetup{format=hang,labelfont=bf,font={small,sf},|\\
%   |              margin=10pt}|\qquad.
% \end{quote}
%
% The quite exotic option |ruled| which allowed a partial usage of
% the caption settings for |ruled| floats defined with the
% \package{float} package will be emulated by this version of the
% caption package, too.
% But using this option is not recommended anymore since this
% version of \thispackage\ offers a more flexible way
% for changing the captions of these floating environments:
% \begin{quote}
%   |\DeclareCaptionStyle{ruled}{|\ldots|}|
% \end{quote}
% resp.
% \begin{quote}
%   |\captionsetup[ruled]{|\ldots|}|\qquad.
% \end{quote}
% \SeeUserDefined[, \Ref{captionsetup}, and \Ref{float}]
%
% \subsection{caption2 v\texorpdfstring{$2.x$}{2.x}}
% \label{caption2}
%
% Although they do very similar stuff, the packages \package{caption} and
% its experimental and now obsolete variant \package{caption2} have a
% very different implementation design.
% Therefore a full compatibility could not be offered.
% For that reason you will still find a file called |caption2.sty| in
% this package distribution, so old documents using the \package{caption2}
% package will still compile fine.
%
% Newly created documents should use the actual version of
% \thispackage\ instead. In most cases it's sufficient to replace the command
% \begin{quote}
%   |\usepackage[...]{caption2}|
% \end{quote}
% by
% \begin{quote}
%   |\usepackage[...]{caption}|\qquad.
% \end{quote}
% But some options and commands will not be emulated, so you can get
% error messages afterwards. This section will hopefully help you removing
% these errors. If you have problems migrating from \package{caption2}
% to \package{caption} please don't hesitate to send me an e-mail asking
% for help.
%
% In addition to the obsolete options shown in the last section
% these ones will be emulated, too:
%
% \begin{center}\small
% \begin{tabular}{ll}
% \package{caption2} \version{2.x} & \package{caption} \version{3.x}\\
% \hline
% |flushleft|   & |justification=raggedright|\\
% |flushright|  & |justification=raggedleft|\\
% |oneline|     & |singlelinecheck=on|\\
% \end{tabular}
% \end{center}
%
% Setting the margin for captions was done in \version{2.x} with
% \begin{quote}\leavevmode\hbox{%
%   |\setcaptionmargin{|\ldots|}| resp.
%   |\setcaptionwidth{|\ldots|}|\quad.
% }\end{quote}
% This was replaced by
% \begin{quote}\leavevmode\hbox{%
%   |\captionsetup{margin=|\ldots|}| resp.
%   |\captionsetup{width=|\ldots|}|\quad.
% }\end{quote}
% \See{\Ref{margins}}
%
% Setting an indention was done in \version{2.x} with
% \begin{quote}
%   |\captionstyle{indent}|\\
%   |\setlength\captionindent{|\ldots|}|\quad.
% \end{quote}
% \pagebreak[3]
% This is now done with
% \nopagebreak[3]
% \begin{quote}
%   |\captionsetup{format=plain,indention=|\ldots|}|\quad.
% \end{quote}
%
% The so-called single-line-check was controlled by the commands
% |\oneline|\-|captions|\-|false| (for switching the check off) and
% |\oneline|\-|captions|\-|true| (for switching the check on).
% This was replaced by
% |\caption|\-|setup{single|\-|line|\-|check=|\x|off}|
% resp.
% |\caption|\-|setup{single|\-|line|\-|check=|\x|on}|\quad.
% \See{\Ref{justification}}
%
% The commands
% \begin{quote}
%   |\captionlabeldelim|, |\captionlabelsep|, |\captionstyle|,\\
%   |\defcaptionstyle|, |\newcaptionstyle|, and |\renewcaptionstyle|
% \end{quote}
% do not have a simple replacement and therefore will not be emulated
% by this version of \thispackage. (So using them will
% cause error messages.) Rewriting such code is not always easy and
% straight-ahead, but by conscientious reading of this manual you should
% be able to find appropriate options and commands instead.
%
% \iffalse
% ... (some examples)
% \fi
%
% The \version{2.x} option |ignore|\-|LT|\-|cap|\-|width| do not have a
% replacement, too.
% But in most cases you can simply drop using that option because
% in this version of \thispackage\ the value of |\LT|\-|cap|\-|width|
% will be ignored anyway (unless you set it to a different value than the
% default one which is |4in|).
% \See{\Ref{longtable}}
%
% \subsection{caption v\texorpdfstring{$3.0$}{3.0}}
% \label{caption3}
%
% \Thispackage\ \version{3.0} did not support any document classes
% other than the standard \LaTeX\ ones: \class{article}, \class{report},
% and \class{book}.
% Therefore the default settings used to be fixed, but now \thispackage{}
% supports more classes, therefore they are now set in dependence on the
% document class used.
%
% For example: While in \version{3.0} the default caption
% |jus|\-|ti|\-|fi|\-|ca|\-|tion| used to be always |jus|\-|ti|\-|fied|,
% it's now still |jus|\-|ti|\-|fied| when using one of the standard document
% classes, but |ragged|\-|right| will be used as default format when used
% with the \class{beamer} document class.
%
% An easy way to select the `old' defaults is using the option
% |style=base| when loading \thispackage\ (or later on using |\caption|\-|setup|).
%
% \medskip
%
% Another new feature is the automatic check for compatibility; if an
% incompatibility will be found, a warning message will be issued and if a strong
% incompatibility was found some features of \thispackage\ will be disabled.
% Please note that only this check was added to \thispackage, so if you get
% such warning message, the previous versions of \thispackage\ were incompatible
% as well, but did not issued such warning, they were ``only'' having
% side-effects or causing problems.
% So these warnings only say that some bad side effects or problems could
% happen, but not that they actually will happen.
% Anyway, if you use \thispackage\ in such circumstances,
% you should use it with care.
%
% \bigskip
%
% \begin{Note*}
% \Thispackage\ \version{3.0} offered the option |caption=|\x|false|,
% which used to be a workaround for not using the whole \package{caption} package
% (leaving the caption stuff offered by the document class or other packages
% intact), but keeping the \package{subfig} package\cite{subfig} working.
% This mechanism is obsolete and not offered anymore, please pass this option
% to the \package{subfig} package instead and do not load \thispackage\ anymore.

% \section{Commands for document class authors}
%
% A document class could simply load the \package{caption} package instead
% of defining an own variant of |\@make|\-|caption|. However if the author decides
% not to do this -- for whatever reason -- there is a second option:
%
% \NEWfeature{v3.5}
% If a document class defines |\caption@document|\-|class|, an adaption to the
% \package{caption} package will be loaded as |caption-|\meta{documentclass}|.sto|
% if the \package{caption} kernel is loaded.
% The goal of this adaption file is changing the default settings of the
% \package{caption} package so simply loading it (without any package options)
% will not make any harm to the look at feel of the captions.
% This gives end-users the opportunity to fine-tune certain aspects of the
% appearance of captions by adding package options, without unwanted
% side-effects on other aspects of the appearance.
%
% In both cases the command |\Set|\-|Caption|\-|Default|
% could be used to adapt the \package{caption} package default values:
%
% \DescribeMacro{\SetCaptionDefault}
% The command
% \begin{quote}
%   |\SetCaptionDefault*|\marg{option}\marg{default value}
% \end{quote}
% changes the default value for the option \meta{option}, for example:
% \begin{quote}
%   |\SetCaptionDefault{format}{hang}|\\
%   |\SetCaptionDefault{justification}{raggedright}|\\
%   |\DeclareCaptionLabelSeparator{silly}{ +++ }|\\
%   |\SetCaptionDefault{labelseparator}{silly}|
% \end{quote}
% This command is available for the options
%   |box|,
%   |font|,
%   |format|,
%   |justification|,
%   |label|\-|font|,
%   |label|\-|format|,
%   |label|\-|separator|,
%   |list|\-|format|,
%   |margin|,
%   |parbox|,
%   |position|,
%   |single|\-|line|\-|check|,
%   |text|\-|font|,
%   |text|\-|format|, and
%   |width|.
%
% The starred variant only makes a difference when setting the default length
% of either |margin| or |width|, in this case it will use |\def| internally
% instead of |\edef| to store the value so the actual margin will be calculated
% when used (and not when set).
%
% \DescribeMacro{\SetCaptionFallback}
% The command
% \begin{quote}
%   |\SetCaptionFallback|\marg{option}\marg{fallback value}
% \end{quote}
% changes the fallback value for the option \meta{option}, for example:
% \begin{quote}
%   |\SetCaptionFallback{labelformat}{simple}|
% \end{quote}
% Currently only the pre-defined label format `original' uses a fallback
% value when |\fnum@|\meta{environment} is not defined for the current (floating)
% environment.
%
% \DescribeMacro{\AtCaptionPackage}
% The adaption file will be loaded when the \package{caption} kernel |caption3.sty|
% will be loaded so the given adaptions will be done for the \package{floatrow}
% and \package{subfig} packages even if the \package{caption} package isn't loaded.
%
% But some adaptions have to be done for the \package{caption} package,
% and for this reason the hook
% \begin{quote}|\AtCaptionPackage|\marg{code}\end{quote}
% is offered to authors of adaption files.
% The \meta{code} inside the hook will be executed right before the given package
% options will be evaluated.
%
% For example the adaption file for the \KOMAScript\ document classes
% uses |\At|\-|Begin|\-|Caption| to re-define the \package{caption} package
% options |figure|\-|position| and |table|\-|position| to issue a warning
% that using these options have little effect here.
%
% \DescribeMacro{\AfterCaptionPackage}
% The additional hook
% \begin{quote}|\AfterCaptionPackage|\marg{code}\end{quote}
% is offered to authors of adaption files as well.
% The \meta{code} inside the hook will be executed at the very end of the
% \package{caption} package.

% \section{Commands for babel language package authors}
%
% \NEWfeature{v3.5}
% \DescribeMacro{\caption@switchdefault}
% If the \package{caption3} kernel package is loaded, the command
% \begin{quote}|\caption@switchdefault|\marg{option}\marg{code with \#1}\marg{new value}\end{quote}
% is available which saves the old default value of the given option using
% \meta{code} and sets the new default value afterwards.
%
% \DescribeMacro{\caption@restoredefault}
% The command
% \begin{quote}|\caption@restoredefault|\marg{option}\marg{old value}\end{quote}
% restores the old default value which was stored in \meta{old value} before.
%
% Example:
% \begin{quote}
%   |\DeclareCaptionLabelSeparator{french}{|\ldots|}|\\
%   |\addto\extrasfrench{%|\\
%   |  \caption@switchdefault{labelseparator}{\babel@save #1}{french}}|\\
%   |% Note: \caption@restoredefault isn't needed here|
% \end{quote}
%
% Another example:
% \begin{quote}
%   |\caption@switchdefault{font}{\let\original@captionfont#1}{it}%|\\
%   \ldots\\
%   |\caption@restoredefault{font}{\original@captionfont}%|\\
% \end{quote}
%
% Since boths commands are defined with |\def| inside the \package{caption3}
% kernel, they could be pre-defined with
% \begin{quote}
%   |\providecommand\caption@switchdefault[3]{}|\\
%   |\providecommand\caption@restoredefault[2]{}|
% \end{quote}
% inside the babel language package so their existence doesn't need to be tested
% prior use.
%
% Additionally babel language packages should not re-define |\@make|\-|caption|
% if the \package{caption} package is loaded, i.e.~if |\caption@makecaption| is
% defined. (Unfortunately one cannot use the \LaTeX{} kernel command
% |\@if|\-|package|\-|loaded{caption}| here since it's only available in the
% document preamble.)
%
% Please note that code like
% \begin{quote}
%   |\addto\extraswhatever{%|\\
%   |  \@ifundefined{caption@makecaption}{%|\\
%   |    \babel@save\@makecaption|\\
%   |    \let\@makecaption\my@makecaption|\\
%   |  }{%|\\
%   |    \caption@switchdefault{|\ldots|}{\babel@save #1}{|\ldots|}%|\\
%   |  }}|
% \end{quote}
% would be wrong since it mixes up the presence of the \package{caption3} kernel
% and the \package{caption} package.
% If the \package{caption3} kernel is loaded this does not mean that the
% \package{caption} package is loaded, too, and the latter one re-defines
% |\caption|, |\@caption|, and |\@make|\-|caption| while the \package{caption3}
% kernel does not re-define any of them, instead it only provides (default) values
% for the \package{caption}, \package{floatrow}, and \package{subfig} package.
%
% Currently there is build-in support for the following babel language options:
% |arabic|, |farsi|, |french|, |hungarian|, |latvian|, and |magyar|.
% This support could be deactivated by defining
% \begin{quote}
%   |\def\caption@ifbabel@|\meta{package}|{false}|
% \end{quote}
% where \meta{package} is either |arabi|, |french|, |frenchle|, |hungarian|,

%
% \subsection{Introduction}
%
% \Thispackage\ consists of two parts -- the kernel
% (|caption3.sty|) and the main package (|caption.sty|).
%
% \Thispackage\ redefines the \LaTeX\ commands
% |\caption|, |\@caption|, and |\@makecaption| and maps the latter one to
% |\caption@@make|, giving the user the possibility to control the look \& feel
% of the captions from floating environments like |figure| and |table|.
% Furthermore it does similar to the caption stuff coming from other packages
% (like the \package{longtable} or \package{supertabular} package):
% Mapping the appropriate internal commands (like |\LT@makecaption| or
% |\ST@caption|) to the ones offered by the \package{caption3} kernel.
% So you can think of \thispackage\ as a layer package, it
% simply provides adaptation layers between the caption stuff coming from
% \LaTeXe\ or packages, and the caption stuff offered by the
% \package{caption3} kernel.
%
% \subsection{Identification}
%
% We need at least \LaTeX2e\ version 1994/12/01.

% \changes{v3.3}{2018/08/08}{This counter and associated macros added}
% Since we support continued floats and sub-figures it's not an easy task
% to manage the figure (and table) counter, especially since previous versions
% of the caption package have proven that correcting a counter locally is not a good idea,
% and to make it dependent on the |position=| setting (like the \package{subfig} package does)
% is not a good idea, either.
%
% In the past three boolean switches were used to store the flags, but since some
% packages (like the \package{floatrow} and \package{tabu} package) try hard to keep
% \LaTeX{} counter changes locally under certain circumstances, it seems a good idea to make
% these flags a \LaTeX{} counter value.

%
% The \package{float} package usually do not use the \LaTeX\ kernel command
% |\@caption| to typeset the caption but |\float@caption| instead.
% (|\@caption| will only be used if the float is re-styled with
% |\restylefloat*|.)
%
% The main two things |\float@caption| is doing different are:
% \begin{itemize}
%   \item The caption will be typeset inside a |\savebox| called |\@floatcapt|
%   so it can be placed above or below the float contents afterwards.
%   \item |\@makecaption| will not be used to finally typeset the caption.
%   Instead |\@fs@capt| will be used which definition is part of the float
%   style.
%   (Note that |\@fs@capt| will not typeset any vertical space above or below
%   the caption; instead this space will be typeset by the float style code
%   itself.)

% \changes{v3.4b}{2019/12/16}{Usage of \cs{caption@float@setname} added}
%  |\@float@setevery|\marg{float type} is provided by the \package{float}
%  package; it's called every time a floating environment defined with
%  |\newfloat| or |\restylefloat| begins.
%  We use this hook to do some adaptations and to setup the proper caption

%  |\captionsetup|\oarg{float style}.

%  First of all we set the caption position to it's proper value by
%  converting |\@fs@iftopcapt| (which is part of a float style and
%  controls where the caption will be typeset, above or below the float
%  contents) to our |position=| setting.
%  Since the spacing above and below the caption will be done by the float
%  style and \emph{not} by us this sounds quite useless. But in fact it isn't,
%  since some packages based on \thispackage\ (like the \package{subfig}
%  package) could have an interest for this information and therefore use the
%  |\caption@iftop| macro we provide in our kernel. Furthermore we need this
%  information for ourself in |\captionof| which uses |\@makecaption| to
%  finally typeset the caption with skips.
%    \begin{macrocode}
      \caption@setposition{\@fs@iftopcapt t\else b\fi}%
%    \end{macrocode}
%
%  Afterward we redefine |\caption@setfloatcapt| (which will be used inside

%  |\caption@makestart|\marg{type}
%  defines a \package{hyperref} anchor inside |\caption@start|.\par
%  Since we offer |\continuedfloat| the float counter can change between
%  `now' and |\caption|, i.e., we simply don't know the figure or table counter
%  yet and therefore we are not able to generate the `right' \package{hyperref}
%  label.
%  Two different solutions of this problem came into my mind:
%  \begin{enumerate}
%  \item I could use the aux file for this purpose.\par
%  -or-
%  \item I set |hypertexnames=false| locally.
%  Furthermore I use |#1.caption.|\meta{counter} (instead of |#1.|\meta{counter})
%  as naming scheme for |\@currentHref| to avoid conflicts with other hyper
%  links which are generated with |hypertexnames=true|.
%  \end{enumerate}
%  The first idea has the advantage that the `right' anchor name will be
%  generated, but one needs an additional \LaTeX\ run if figures or tables
%  will be inserted or removed.\par
%  The second idea has the advantage that it's very easy to implement, but
%  has some side-effects, e.g. the anchor names don't follow the figure or
%  table label names anymore.\par
%  Since I'm lazy I implemented the second idea, maybe I will revise this
%  later on.
