% \section{Introduction}
% 
% Within the standard \LaTeX\ 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{belowskip=\abovecaptionskip}{\figuretext}
% 
% There should be possibilities to change this; for example, it would be nice
% if you could 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{belowskip=\abovecaptionskip,size=small,margin=10pt,labelfont=bf,labelsep=endash}{\figuretext}
% 
% 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.

% \section{Using the package}
% \label{usage}
% 
% \DescribeMacro{\usepackage}
% 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 |\documentclass| and |\begin{document}|.
% The options control how your captions will look like; e.g.,
% \begin{quote}
%   |\usepackage[margin=10pt,font=small,labelfont=bf]{caption}|
% \end{quote}
% would result in captions looking like the second one in the introduction.
% 
% \DescribeMacro{\captionsetup}
% For a later change of options the \thispackage\ package provides the command
% \begin{quote}
%   |\captionsetup|\oarg{float type}\marg{options}
% \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 |\captionsetup| has an effect on the current
% environment only. So if you want to change some settings for the
% current |figure| or |table| only, just place the |\captionsetup| 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.
% 
% (For a description of the optional parameter \meta{float type} see
%  section \ref{misc}: \textit{``Useful stuff''}.)

% \subsection{Formatting}
% 
% \DescribeMacro{format=}
% A figure or table caption mainly consits 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:
% \iffalse
% \footnote{You have the option to
% define your own ones, too. See section \ref{declare}:
% \textit{``Do it yourself!''} for details.}
% \fi
% 
% \begin{Options}{\OptionLabel}
%   \item[plain]\NEWdescription{v3.0h}
%   Typesets the captions as a normal paragraph.
%   (This is the default behaviour, it
%   is adapted from the standard \LaTeX\ document classes.)
% 
%   \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 |\DeclareCaptionFormat|.
%   \SeeUserDefined
% \end{Options}
% 
% \begin{Example}
%   An example: Specifying the option
%   \begin{quote}
%     |format=hang|
%   \end{quote}
%   yields captions like this:
%   \example{format=hang}{\figuretext}
% \end{Example}
% 
% \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}.
% \end{quote}
% 
% Two examples:
% 
% \begin{Example}
%   \begin{quote}
%     |format=plain,indention=.5cm|
%   \end{quote}
%   \captionsetup{aboveskip=0pt}
%   \example{format=plain,indention=.5cm}{\figuretext}
% \end{Example}
% 
% \begin{Example}
%   \begin{quote}
%     |format=hang,indention=-0.5cm|
%   \end{quote}
%   \captionsetup{aboveskip=0pt}
%   \example{format=hang,indention=-0.5cm}{\figuretext}
% \end{Example}
% 
% \pagebreak[3]
% \DescribeMacro{labelformat=}
% With the option
% \nopagebreak[3]
% \begin{quote}
%   |labelformat=|\meta{label format name}
% \end{quote}
% \NEWdescription{v3.0e}
% you specify how the caption label will be typeset.
% There are four standard caption label formats:
% 
% \begin{Options}{\OptionLabel}
%   \item[default]
%   The caption label will be typeset as specified by the document class,
%   usually this means the name and the number (like \texttt{simple}).
%   (This is the default behaviour.)
%
%   \item[empty]
%   The caption label will be empty. (This option makes sense when used
%   together with other options like \texttt{labelsep=none}.)
% 
%   \item[simple]
%   The caption label will be typeset as a name and a number.
% 
%   \item[parens]
%   The number of the caption label will be typeset in parentheses.
% 
%   \item[\UserDefined]
%   Own label formats can be defined using |\DeclareCaptionLabelFormat|.
%   \SeeUserDefined
% \end{Options}
% 
% \begin{Example}
%   An example: Using the options
%   \begin{quote}
%     |labelformat=parens,labelsep=quad|
%   \end{quote}
%   gives captions like this one:
%   \example{labelformat=parens,labelsep=quad}{\figuretext}
% \end{Example}
% 
% \DescribeMacro{labelsep=}
% With the option
% \begin{quote}
%   |labelsep=|\meta{label separator name}
% \end{quote}
% you specify what caption separator will be used.
% You can choose one of the following:
% 
% \begin{Options}{\OptionLabel}
%   \item[none]
%   There is no caption separator. (This option makes sense when used
%   together with other options like \texttt{labelformat=empty}.)
% 
%   \item[colon]
%   The caption label and text will be separated by a colon and a space.
%   (This is the default one.)
% 
%   \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 (|\\|).
% 
%   \item[endash]\NEWfeature{v3.0h}
%   The caption label and text will be separated by an en-dash,
%   surrounded by spaces (| -- |).
% 
%   \item[\UserDefined]
%   Own separators can be defined using |\DeclareCaptionLabelSeparator|.
%   \SeeUserDefined
% \end{Options}
% 
% Three examples:
% \begin{Example}
%   \begin{quote}
%     |labelsep=period|
%   \end{quote}
%   \captionsetup{aboveskip=0pt}
%   \example{labelsep=period}{\figuretext}
% \end{Example}
% 
% \begin{Example}
%   \begin{quote}
%     |labelsep=newline,singlelinecheck=false|
%   \end{quote}
%   \captionsetup{aboveskip=0pt}
%   \example{labelsep=newline,singlelinecheck=false}{\figuretext}
% \end{Example}
% 
% \begin{Example}
%   \begin{quote}
%     |labelsep=endash|

%   \example{labelsep=endash}{\figuretext}
% \end{Example}
%
% \iffalse
% --------------------------------------------------------------------------- %
% \fi
% 
% \subsection{Justification}
% \label{justification}
% 
% \DescribeMacro{justification=}
% As addition to the caption format you could also specify a
% \emph{caption justification}; it is specified with the option
% \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. (This is the default.)
% 
%   \item[centering]
%   Each line of the caption will be centered.
% 
% \iffalse
%   \item[Centering]
%   Each line of the caption will be centered, too.
%   But this time the command |\Centering| of the \package{ragged2e} package
%   will be used to achieve this. This difference is that this time the word
%   breaking algorithm of \TeX\ will work inside the caption.
% \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.
% \fi
%   \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 is that the word
%   breaking algorithm of \TeX\ will work inside captions.
% 
%   \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
%   the command |\RaggedLeft| from the \package{ragged2e} package.
% \fi
% 
%   \item[\UserDefined]
%   Own justifications can be defined using |\DeclareCaptionJustification|.
%   \SeeUserDefined
% \end{Options}
% 
% Three examples:
% \begin{Example}
%   \begin{quote}
%     |justification=centerlast|
%   \end{quote}
%   \captionsetup{aboveskip=0pt}
%   \example{justification=centerlast}{\figuretext}
% \end{Example}
% 
% \begin{Example}
%   \begin{quote}
%     |format=hang,justification=raggedright|
%   \end{quote}
%   \captionsetup{aboveskip=0pt}
%   \example{format=hang,justification=raggedright}{\figuretext}
% \end{Example}
% 
% \begin{Example}
%   \begin{quote}
%     |labelsep=newline,justification=centering|
%   \end{quote}
%   \captionsetup{aboveskip=0pt}
%   \example{belowskip=\abovecaptionskip,labelsep=newline,justification=centering}{\figuretext}
% \end{Example}
% 
% \DescribeMacro{singlelinecheck=}
% The standard \LaTeX\ document classes (|article|, |report|, and |book|)
% automatically center a caption if it fits in one single line:
%
% \example{belowskip=\abovecaptionskip}{A short caption.}
%
% \DANGER
% The \thispackage\ package adapts this behaviour and therefore usually
% ignores the justification you have set with |justification=| in such case.
% But you can switch this special treatment of such short captions off
% with the option
% \begin{quote}
%   |singlelinecheck=|\meta{bool}\quad.
% \end{quote}
% Using |false|, |no|, |off| or |0| for \meta{bool} switches the
% extra centering off:
% \begin{quote}
%   |singlelinecheck=false|
% \end{quote}
% Doing so the above short caption would look like
% 
% \begingroup
% \captionsetup{type=figure}
% \ContinuedFloat
% \endgroup
% \example{belowskip=\abovecaptionskip,singlelinecheck=false}{A short caption.}
% 
% You switch the extra centering on again by using |true|, |yes|, |on| or |1|
% for \meta{bool}. (The default is on.)
% 
% \iffalse
% --------------------------------------------------------------------------- %
% \fi
% 
% \subsection{Fonts}
% \label{fonts}
% 
% \DescribeMacro{font=}
% \DescribeMacro{labelfont=}
% \DescribeMacro{textfont=}
% There are three font options which affects different parts of the caption:
% One affecting the whole caption (|font|), one which only affects the caption
% label and separator (|labelfont|) and at least one which only affects the
% caption text (|textfont|).
% You set them up using the options
% \begin{quote}\begin{tabular}{@{}r@{}ll}
%   |font=|      & \marg{font options} & ,\\
%   |labelfont=| & \marg{font options} & , and\\
%   |textfont=|  & \marg{font options} & .\\
% \end{tabular}\end{quote}
% 
% And these are the available font options:
% 
% \begin{Options}{\OptionLabel}
%   \item[scriptsize]   {\scriptsize Very small size}
%   \item[footnotesize] {\footnotesize The size usually used for footnotes}
%   \item[small]        {\small Small size}
%   \item[normalsize]   {\normalsize Normal size}
%   \item[large]        {\large Large size}
%   \item[Large]        {\Large Even larger size}
% 
%   \item[up]           {\upshape Upright shape}
%   \item[it]           {\itshape Italic shape}
%   \item[sl]           {\slshape Slanted shape}
%   \item[sc]           {\scshape Small Caps shape}
% 
%   \item[md]           {\mdseries Medium series}
%   \item[bf]           {\bfseries Bold series}
% 
%   \item[rm]           {\rmfamily Roman family}
%   \item[sf]           {\sffamily Sans Serif family}
%   \item[tt]           {\ttfamily Typewriter family}
% 
%   \item[\UserDefined]
%   Own font options can be defined using |\DeclareCaptionFont|.
%   \SeeUserDefined
% \end{Options}
% 
% If you use only one of these options you can omit the braces;
% e.g., the options
% \iffalse
% \begin{quote}
% \fi
%   |font={small}|
% \iffalse
% \end{quote}
% \fi
% and
% \iffalse
% \begin{quote}
% \fi
%   |font=small|
% \iffalse
% \end{quote}
% \fi
% will give the same result.
% 
% Two examples:
% \begin{Example}
%   \begin{quote}
%     |font={small,it},labelfont=bf|
%   \end{quote}
%   \captionsetup{aboveskip=0pt}

% 
% \subsection{Margins and further paragraph options}
% \label{margins}
% 
% \DescribeMacro{margin=}
% \DescribeMacro{width=}
% For all captions you can specify \emph{either} an extra margin \emph{or}
% a fixed width. You do this by using the options
% \begin{quote}\begin{tabular}{@{}r@{}ll}
%   |margin=| & \meta{amount}   & \emph{or}\\
%   |width=|  & \meta{amount} & \\
% \end{tabular}\end{quote}
% Nevertheless what option you use, the left and right margin will be the
% same.
% 
% Two examples will illustrating this:
% \begin{Example}
%   \begin{quote}
%     |margin=10pt|
%   \end{quote}
%   \captionsetup{aboveskip=0pt}
%   \example{margin=10pt}{\figuretext}
% \end{Example}
% 
% \begin{Example}
%   \begin{quote}
%     |width=.75\textwidth|
%   \end{quote}
%   \captionsetup{aboveskip=0pt}
%   \example{width=.75\textwidth}{\figuretext}
% \end{Example}
% 
% \DescribeMacro{parskip=}
% This option is useful for captions containing more than one paragraph.
% It specifies the extra vertical space inserted between them:
% \begin{quote}
%   |parskip=|\meta{amount}
% \end{quote}
% One example:
% \begin{Example}
%   \begin{quote}
%     |margin=10pt,parskip=5pt|
%   \end{quote}
%   \captionsetup{aboveskip=0pt}
%   \example{margin=10pt,parskip=5pt}{
%     First paragraph of the caption. This one contains some test, just to
%     show how these options affect the layout of the caption.
% 
%     Second paragraph of the caption. This one contains some text, too, to
%     show how these options affect the layout of the caption.}
% \end{Example}
% 
% \DescribeMacro{hangindent=}
% The option
% \begin{quote}
%   |hangindent=|\meta{amount}
% \end{quote}
% is for setting up a hanging indention starting from the second line of each
% paragraph. If the caption contains just a single paragraph, using this option
% leads to the same result as the option |indention=| you already know about.
% But if the caption contains multiple paragraphs you will notice the difference:
% 
% \begin{Example}
%   \begin{quote}
%     |format=hang,indention=-.5cm|
%   \end{quote}
%   \captionsetup{aboveskip=0pt}
%   \example{format=hang,indention=-.5cm}{
%     First paragraph of the caption. This one contains some test, just to
%     show how these options affect the layout of the caption.
% 
%     Second paragraph of the caption. This one contains some text, too, to
%     show how these options affect the layout of the caption.}
% \end{Example}
% 
% \begin{Example}
%   \begin{quote}
%     |format=hang,hangindent=-.5cm|

% \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
% |\pagestyle|: 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}
% The \thispackage\ package usually defines only the style |default| which
% puts all options you already know about to the default ones.
% This means that specifying the option
% \begin{quote}
%   |style=default|
% \end{quote}
% has the same effect as specifying all 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}
% 
% Own caption styles can be defined using |\DeclareCaptionStyle|.

% 
% \subsection{Skips}
% 
% \DescribeMacro{aboveskip=}
% \DescribeMacro{belowskip=}
% The spaces above and below the caption are controlled by the skips
% |\abovecaptionskip| and |\belowcaptionskip|. The standard \LaTeX\ document
% classes |article|, |report| and |book| set |\abovecaptionskip| to |10pt|
% and |\belowcaptionskip| to |0pt|.
%
% \pagebreak[3]
% Both skips can be changed with the command |\setlength|, but you can
% use these options, too:
% \nopagebreak[3]
% \begin{quote}\begin{tabular}{@{}r@{}ll}
%   |aboveskip=| & \meta{amount} & and\\
%   |belowskip=| & \meta{amount} & .\\
% \end{tabular}\end{quote}
%
% \DescribeMacro{position=}
% Using |\abovecaptionskip| and |\belowcaptionskip| has a major design flaw:
% If the caption is typeset \emph{above} (and not \emph{below}) the figure
% or table they are not set up very useful at default, because there will be
% some extra space above the caption but no space between the caption and the
% figure or table itself. (Remember: |\belowcaptionskip| is usually set to |0pt|.)
% 
% Please compare the spacing in these small tables:
% \begin{Example}
%   \begin{minipage}[c]{.5\linewidth}
% \iffalse
%     \captionsetup{aboveskip=0pt}%
% \fi
%     \captionof{table}{A table}
%     \centering\begin{tabular}{ll}
%       A & B \\
%       C & D \\
%     \end{tabular}
%   \end{minipage}
%   \begin{minipage}[c]{.5\linewidth}
%     \centering\begin{tabular}{ll}
%       A & B \\
%       C & D \\
%     \end{tabular}
%     \captionof{table}{A table}
%   \end{minipage}
% \end{Example}
% 
% But you can fix this by using the option |position=|: It specifies how the
% spacing above and below the caption will be used:
% \begin{quote}
%   |position=top|\quad(or |position=above|)
% \end{quote}
% tells the \thispackage\ package to use the spacing useful for caption
% \emph{above} the figure or table and
% \begin{quote}
%   |position=bottom|\quad(or |position=below|)
% \end{quote}
% tells the \thispackage\ package to use the spacing useful for captions
% \emph{below} the figure or table. (The last one is the default setting
% except for |longtable|s.)
% 
% So adding an extra |\captionsetup{position=top}| to the left example
% table gives you proper spacing around both captions:
% \begin{Example}
%   \begin{minipage}[c]{.5\linewidth}
%     \captionsetup{position=top}
%     \captionof{table}{A table}
%     \centering\begin{tabular}{ll}
%       A & B \\
%       C & D \\
%     \end{tabular}
%   \end{minipage}
%   \begin{minipage}[c]{.5\linewidth}
%     \centering\begin{tabular}{ll}
%       A & B \\
%       C & D \\
%     \end{tabular}
%     \captionof{table}{A table}
%   \end{minipage}
% \end{Example}
%
% (Technically speaking |\abovecaptionskip| and |\belowcaptionskip| will
% be swapped if you specify the option |position=top|, so in both cases
% |\abovecaptionskip| will be used between the caption and the figure or
% table itself.)
% 
% This option is especially useful when used together with the optional
% argument of the |\captionsetup| command.
% \See{\Section{misc}{Useful stuff} for details}\par
% For example
% \begin{quote}
%   |\captionsetup[table]{position=top}|
% \end{quote}
% causes all captions within tables to be treated as captions \emph{above}
% the table (regarding spacing around it).
% \DescribeMacro{tableposition=}
% \NEWfeature{v3.0a}
% Because this is a very common setting the \thispackage\ package offers
% an abbreviating option for the use with |\usepackage|:
% \begin{quote}
%   |\usepackage[|\ldots|,tableposition=top]{caption}|\footnote{Please
%   note that this is \emph{not} sufficient when using a
%   \KOMAScript\ document class, you need to use the \emph{global}
%   option |tablecaptionabove|, too.}
% \end{quote}
% is equivalent to
% \begin{quote}
%   |\usepackage[|\ldots|]{caption}|\\

% 
% \DescribeMacro{\caption}
% The command
% \nopagebreak[3]
% \begin{quote}
%   |\caption|\oarg{lst\_entry}\marg{heading}
% \end{quote}
% \nopagebreak[3]
% typesets the caption inside a floating environment like |figure| or |table|.
% Well, you already know this, but the \thispackage\ package offers an extension:
% If you leave the argument \meta{lst\_entry} empty, no entry in the list of
% figures or tables will be made. For example:
% \begin{quote}
%   |\caption[]{A figure without entry in the list of figures.}|
% \end{quote}
% 
% \DescribeMacro{\caption*}
% 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}{cc}|\\
%   |  \caption*{A table}\\|\\
%   |  A & B \\|\\
%   |  C & D \\|\\
%   |\end{longtable}|
% \end{quote}
% looks like
% \begin{longtable}{cc}
%   \caption*{A table}\\
%   A & B \\
%   C & D \\
% \end{longtable}
% 
% This package offers this feature, too, so you can use this command now within
% every floating environment like |figure| or |table|, like:
% \begin{quote}
%   |\begin{table}|\\
%   |  \caption*{A table}|\\
%   |  \begin{tabular}{cc}|\\
%   |    A & B \\|\\
%   |    C & D \\|\\
%   |  \end{tabular}|\\
%   |\end{table}|
% \end{quote}
% 
% \DescribeMacro{\captionof}
% \DescribeMacro{\captionof*}
% Sometimes you want to typeset a caption \emph{outside} a floating environment,
% putting a figure within a |minipage| for instance. For this purpose the
% \thispackage\ package offers the command
% \begin{quote}
%   |\captionof|\marg{float type}\oarg{lst\_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{figure}{A figure}|\\
%   |\captionof{table}{A table}|
% \end{quote}
% typesets captions like this:
% \begin{Example}
%   \captionof{figure}{A figure}
%   \captionsetup{belowskip=\abovecaptionskip}
%   \captionof{table}{A table}
% \end{Example}
% 
% The star variant |\captionof*| has the same behaviour as the |\caption*| command:
% it typesets the caption without label and without entry to the list of figures
% or tables.
%
% Please use both |\captionof| and |\captionof*| only \emph{inside} environments
% (like |minipage| or |\parbox|), otherwise a page break can appear between content
% and caption. Furthermore some strange effects could occur (e.g., wrong spacing
% around captions).
% 
% \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 increment of the relevant counter (usually done by |\caption|)
% so a figure or table with a |\ContinuedFloat| in it 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}
%   \makeatletter\def\@captype{table}\makeatother
%   \caption[]{A table}
%   \centerline{\ldots}
%   \ContinuedFloat
%   \captionsetup{aboveskip=0pt}
%   \caption[]{A table (cont.)}
% \end{Example}
% 
% \DescribeMacro{\captionsetup}
% We already know the |\captionsetup| command (see \Section{usage}
% {Using the package}), 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}|
% \end{quote}
% gives captions like this:
% \begin{Example}
%   \captionsetup{font=small}
%   \captionsetup[figure]{labelfont=bf}
%   \captionof{figure}[]{A figure}
%   \captionsetup{belowskip=\abovecaptionskip}
%   \captionof{table}[]{A table}
% \end{Example}
% 
% As you see the command |\captionsetup[figure]{labelfont=bf}| only changed
% the font of the figure caption labels, not touching all other ones.
% 
% \DescribeMacro{\clearcaptionsetup}
% If you want to get rid of these parameters marked for an automatic use within
% a particular environment you can use the command
% \begin{quote}
%   |\clearcaptionsetup|\marg{float type}\quad.
% \end{quote}
%
% For example |\clearcaptionsetup{figure}| would clear the extra handling in the
% example above:
% \begin{Example}
%   \captionsetup{font=small}
%   \captionof{figure}[]{A figure}
%   \captionsetup{belowskip=\abovecaptionskip}
%   \captionof{table}[]{A table}
% \end{Example}
% 
% 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{float}, \package{longtable}, and \package{sidecap} package
% for example) offer additional floating environments and these two
% commands can also be used with them.

% \section{Do it yourself!}
% \label{declare}
% 
% A family of commands is provided to allow users to define their own formats.
% This enables information on separators, justification, fonts, and styles to
% be associated with a name and kept in one place
% (these commands need to appear in the document preamble,
% this is the part between |\documentclass| and |\begin{document}|).
% 
% \pagebreak[2]
% \DescribeMacro{\DeclareCaptionFormat}
% You can define your own caption formats using the command
% \begin{quote}
%   |\DeclareCaptionFormat|\marg{name}\marg{code using \#1, \#2 and \#3}\quad.
% \end{quote}
% At usage the system replaces \#1 with the caption label, \#2 with the
% separator and \#3 with the text. So the standard format |plain| is
% pre-defined by the \thispackage\ package as
% \begin{quote}
%   |\DeclareCaptionFormat{plain}{#1#2#3\par}|
% \end{quote}
% 
% \DescribeMacro{\DeclareCaptionLabelFormat}
% Likewise you can define your own caption label formats:
% \begin{quote}
%   |\DeclareCaptionLabelFormat|\marg{name}\marg{code using \#1 and \#2}
% \end{quote}
% At usage \#1 gets replaced with the name (e.g. ``figure'') and \#2
% gets replaced with the reference number (e.g. ``12'').
% 
% \DescribeMacro{\bothIfFirst}
% \DescribeMacro{\bothIfSecond}
% If you define your own caption label formats and use the \package{subfig}
% package\cite{subfig}, you should take care of empty caption label names.
% For this purpose the commands
% \begin{quote}
%   |\bothIfFirst|\marg{first arg}\marg{second arg}\quad and\\
%   |\bothIfSecond|\marg{first arg}\marg{second arg}
% \end{quote}
% are offered. |\bothIfFirst| tests if the first argument exists (means: is
% not empty), |\bothIfSecond| tests if the second argument exists. If yes,
% both arguments get typeset, otherwise none of them.
% 
% For example the standard label format |simple| is \emph{not} defined as
% \begin{quote}
%   |\DeclareCaptionLabelFormat{simple}{#1 #2}|\quad,
% \end{quote}
% because this could cause an extra space if \#1 is empty. Instead |simple|
% is defined as
% \begin{quote}
%   |\DeclareCaptionLabelFormat{simple}{\bothIfFirst{#1}{ }#2}|\quad,
% \end{quote}
% causing the space to appear only if the label name is present.
% 
% \pagebreak[3]
% \DescribeMacro{\DeclareCaptionLabelSeparator}
% You can define your own caption label separators with
% \nopagebreak[3]
% \begin{quote}
%   |\DeclareCaptionLabelSeparator|\marg{name}\marg{code}\quad.
% \end{quote}
% \nopagebreak[3]
% Again an easy example taken from the \thispackage\ package itself:
% \nopagebreak[3]
% \begin{quote}
%   |\DeclareCaptionLabelSeparator{colon}{: }|
% \end{quote}
% \pagebreak[3]
% 
% \DescribeMacro{\DeclareCaptionJustification}
% You can define your own caption justifications with
% \begin{quote}
%   |\DeclareCaptionJustification|\marg{name}\marg{code}\quad.
% \end{quote}
% The \meta{code} simply gets typeset just before the caption.
% E.g.~using the justification |raggedright|, which is defined as
% \begin{quote}
%   |\DeclareCaptionJustification{raggedright}{\raggedright}|\quad,
% \end{quote}
% lets captions with all lines moved to the left margin.
% 
% \DescribeMacro{\DeclareCaptionFont}
% You can define your own caption fonts with
% \begin{quote}
%   |\DeclareCaptionFont|\marg{name}\marg{code}\quad.
% \end{quote}
% For example this package defines the options |small| and |bf| as
% \begin{quote}
%   |\DeclareCaptionFont{small}{\small}|\quad and\\
%   |\DeclareCaptionFont{bf}{\bfseries}|\quad.
% \end{quote}
% The line spacing could be customized using the \package{setspace} package,
% for example:\NEWdescription{v3.0h}
% \begin{quote}
%   |\usepackage{setspace}|\\
%   |\DeclareCaptionFont{singlespacing}{\setstretch{1}}|\quad\footnote{%
%   \emph{Note:} Using \cs{singlespacing} does not work here since it contains
%   a \cs{vskip} command.}\\
%   |\DeclareCaptionFont{onehalfspacing}{\onehalfspacing}|\\
%   |\DeclareCaptionFont{doublespacing}{\doublespacing}|\\
%   |\captionsetup{font={onehalfspacing,small},labelfont=bf}|
% \end{quote}
% \example{font={onehalfspacing,small},labelfont=bf,singlelinecheck=off}\figuretext
% An example which brings color into life:
% \begin{quote}
%   |\usepackage{color}|\\
%   |\DeclareCaptionFont{red}{\color{red}}|\\
%   |\DeclareCaptionFont{green}{\color{green}}|\\
%   |\DeclareCaptionFont{blue}{\color{blue}}|\\
%   |\captionsetup{labelfont=blue,textfont=green}|
% \end{quote}
% \example{labelfont=blue,textfont=green,singlelinecheck=off}\figuretext
% 
% \DescribeMacro{\DeclareCaptionStyle}
% You can define your own caption styles with
% \begin{quote}
%   |\DeclareCaptionStyle|\marg{name}\oarg{additional options}\marg{options}
% \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 default set of options. (See \Section
% {style}{Styles} 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 |singlelinecheck=off|.
% 
% Again a very easy example taken from the core of this package: The
% caption style |default| is pre-defined as
% \begin{quote}
%   |\DeclareCaptionStyle{default}[justification=centering]{}|\quad.
% \end{quote}
% 
% \iffalse
% --------------------------------------------------------------------------- %
% \fi
% 
% \subsection{Further Examples}
% 
% If you would like to have a colon \emph{and} a line break as caption
% separator you could define it this way:
% \begin{quote}
%   |\DeclareCaptionLabelSeparator{period-newline}{. \\}|
% \end{quote}
% Selecting this separator with |\captionsetup{labelsep=period-newline}| you
% get captions like this:
% \begin{Example}
%   \captionsetup{labelsep=period-newline,labelfont=bf,margin=10pt}
%   \captionsetup{aboveskip=0pt,type=figure}
%   \caption[]{\figuretext}
% \end{Example}
% 
% For short captions---which fit into one single line---this separator
% may not be satisfying, even when the automatically centering process
% is switched off (with |singlelinecheck=off|):
% \begin{Example}
%   \captionsetup{labelsep=period-newline,labelfont=bf,margin=10pt,singlelinecheck=0}
%   \captionsetup{aboveskip=0pt,type=figure}
%   \caption[]{A figure.}
% \end{Example}
% 
% An own caption style which selects another caption separator automatically
% puts this right:
% \begin{quote}
%   |\DeclareCaptionStyle{period-newline}%|\\
%   |  [labelsep=period]{labelsep=period-newline}|
% \end{quote}
% \begin{Example}
%   \captionsetup{style=period-newline,labelfont=bf,margin=10pt}
%   \captionsetup{aboveskip=0pt,type=figure}
%   \ContinuedFloat
%   \caption[]{A figure.}
% \end{Example}
% If you would like to keep the centering of these captions instead, an
% appropriate definition would be something like
% \begin{quote}
%   |\DeclareCaptionStyle{period-newline}%|\\
%   |  [labelsep=period,justification=centering]%|\\
%   |  {labelsep=period-newline}|\quad.
% \end{quote}
% Using this definition short captions look like
% \begin{Example}
%   \captionsetup{style=period-newline2,labelfont=bf,margin=10pt}
%   \captionsetup{aboveskip=0pt,type=figure}
%   \ContinuedFloat
%   \caption[]{A figure.}
% \end{Example}
% while long ones still have a line break after the caption label.
% 
% Slightly changed, you also get centered captions if they are longer than
% one line:
% \begin{quote}
%   |\DeclareCaptionStyle{period-newline}%|\\
%   |  [labelsep=period]%|\\
%   |  {labelsep=period-newline,justification=centering}|
% \end{quote}
% \begin{Example}
%   \captionsetup{style=period-newline3,labelfont=bf,margin=10pt}
%   \captionsetup{aboveskip=0pt,type=figure}
%   \caption[]{\figuretext}
% \end{Example}
%
% \bigskip\pagebreak[3]
% Another example: You want captions to look like this:
% \begin{Example}
%   \captionsetup{format=reverse,labelformat=fullparens,labelsep=fill,font=small,labelfont=it}
%   \captionsetup{aboveskip=0pt}
%  \captionof{figure}[]{\figuretext}
% \end{Example}
% \pagebreak[2]
% You could do it this way:
% \nopagebreak[3]
% {\leftmargini=10pt
%  \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}}
%
% \bigskip\pagebreak[3]
% Another example: The caption text should go into the left margin; a possible
% solution would be:
% {\leftmargini=10pt
%  \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:
% \begin{Example}
%   \captionsetup{format=llap,singlelinecheck=no,labelsep=quad}
%   \captionsetup{aboveskip=0pt}
%   \captionof{figure}[]{\figuretext}

% \section{Using non-standard document classes}
% 
% \NEWdescription{v3.0d}
% The \thispackage\ package was developed using the standard document classes
% |article|, |report| and |book|.
% 
% If you would like to use the \thispackage\ package with the
% \KOMAScript\ classes or with the \package{memoir} class, you have to take
% into consideration that all the possibilities for customization of the
% captions the \KOMAScript\ classes or \package{memoir} class have
% to offer will get lost. (And they have a lot of possibilities to offer!)
% So class commands like |\captionformat|, |\figureformat|, |\tableformat|,
% |\setcapindent|, |\setcaphanging|, |\captionstyle| etc.\ will not work
% anymore. So make a wise decision!
% 
% Using the \thispackage\ package together with document classes not mentioned
% so far is not recommended at the moment -- unwanted layout changes,
% side effects or failures could occur. (But future versions of the
% \thispackage\ package will contain adaptations for more document classes!)
% 
% \iffalse
% --------------------------------------------------------------------------- %
% \fi
% 
% \section{Using other packages}
% \label{packages}
% 
% The \thispackage\ package contains special adaptations to other packages,
% so the captions should always look like you have specified them to look like.
%
% These are the packages the \thispackage\ package is adapted to:
% 
% \begin{tabular}{ll}
%   |float|        & Gives you the possibility to define new floating environments\\
%   |listings|     & Typesets source code listings\\
%   |longtable|    & Typesets tables spanned over multiple pages\\
%   |rotating|     & Supports rotated figures and tables\\
%   |sidecap|      & Offers captions \emph{beside} figures or tables\\
%   |supertabular| & Typesets tables spanned over multiple pages\\
% \end{tabular}
% 
% \NEWfeature{v3.0b}
% If you use one of the above packages together with the {\thispackage} package
% you get the additional possibility to set up captions with
% \begin{quote}|\captionsetup|\oarg{environment}\marg{options}\quad,\end{quote}
% where \meta{environment} stands for any environment the above packages offer.
% (Please note that this do not work with the |sideways| environments offered by
% the \package{rotating} package.)
% For example
% \begin{quote}|\captionsetup[lstlisting]{labelfont=bf}|\end{quote}
% forces captions inside the |lstlisting| environment to have bold labels.
% 
% If a certain support is not desired you can switch it off using the
% \thispackage\ package option
% \begin{quote}
%   |\usepackage[|\ldots|,|\meta{package}|=no]{caption}|\quad.
% \end{quote}
% For example specifying the option |float=no| means you don't like the
% \thispackage\ package to support the \package{float} package.
% (Note: You can specify these options only within the |\usepackage| command,
%  especially \emph{not} at a later time with |\captionsetup|.)
% 
% For further information about the packages mentioned above please take a look
% at the documentation belonging to them or buy yourself

% \subsection{The \package{float} package}
% \label{float}
% 
% A very useful feature is provided by the \package{float} package\cite{float}:
% It offers the float placement specifier |H| which is much more restrictive
% than the specifier |h| offered by \LaTeX. While the latter one is only a
% recommendation to \LaTeX\ to set the float ``here'', the |H| forces the
% float to appear exactly at the spot where it occurs in your input file
% and nowhere else.
%
% Furthermore it offers different styles for floating environments, these
% styles are |plain|, |plaintop|, |ruled|, and |boxed|.
% You can link one of these styles to either new floating environments or
% to one of the existing environments |figure| and |table|.
% 
% If you are using the \thispackage\ package together with the \package{float}
% package a caption style called |ruled| gets defined automatically:
% \begin{quote}
%   |\DeclareCaptionStyle{ruled}{labelfont=bf,labelsep=space}|
% \end{quote}
% This style represents the caption layout in |ruled| styled floats.
% For you as an end user this means that captions within |ruled| floats will
% always look like this, nevertheless what generic caption options do you
% specify:
% 
% \ifx\floatstyle\undefined
% 
% \begin{Example}
% \hrule height.8pt depth0pt \kern2pt
% \vbox{\strut{\bfseries Program 7.1}
%    The first program. This hasn't got anything to do with the package
%    but is included as an example. Note the \texttt{ruled} float style.}
% \kern2pt\hrule\kern2pt
% \begin{verbatim}
% #include <stdio.h>
% 
% int main(int argc, char **argv)
% {
%        for (int i = 0; i < argc; ++i)
%                printf("argv[%d] = %s\n", i, argv[i]);
%        return 0;
% }
% \end{verbatim}
% \kern2pt\hrule\relax
% \end{Example}
% 
% \else
% 
% \floatstyle{ruled}
% \newfloat{Program}{tbp}{lop}[section]
% \floatname{Program}{Program}
% 
% \begin{Program}[H]
% \begin{verbatim}
% #include <stdio.h>
% 
% int main(int argc, char **argv)
% {
%        for (int i = 0; i < argc; ++i)
%                printf("argv[%d] = %s\n", i, argv[i]);
%        return 0;
% }
% \end{verbatim}
% \caption{The first program. This hasn't got anything to do with the package
%    but is included as an example. Note the \texttt{ruled} float style.}
% \end{Program}
% 
% \fi
% 
% If you want a different layout for |ruled| captions you have to define
% your own one using the command
% \begin{quote}
%   |\DeclareCaptionStyle{ruled}|\marg{options}\quad.
% \end{quote}
% 
% This mechanism also works with all other float styles. If you want a special
% caption layout---for |plain| or |boxed| floats for example---you can simply define
% a suitable caption style with the same name as the float style.
% 
% \textbf{Note:} For successful cooperation you need the float package
% version 1.3 or newer.

% \subsection{The \package{listings} package}
% \label{listings}
% 
% \NEWdescription{v3.0b}
% The \package{listings} package\cite{listings} is a source code printer for \LaTeX.
% You can typeset stand alone files as well as listings with an environment
% similar to \texttt{verbatim} as well as you can print code snippets using
% a command similar to |\verb|.
% Many parameters control the output and if your preferred programming
% language isn't already supported, you can make your own definition.
%
% \textbf{Note:} For successful cooperation you need the listings package
% version 1.2 or higher. You'll get an error message when using an
% older version!

% 
% \subsection{The \package{longtable} package}
% \label{longtable}
% 
% The \package{longtable} package\cite{longtable} offers the environment
% |longtable| which behaves similar to the |tabular| environment, but
% the table itself can span multiple pages.
%
% \textbf{Note:} For successful cooperation you need the longtable package
% version 3.15 or newer.

% --------------------------------------------------------------------------- %
% \fi
% 
% \subsection{The \package{rotating} package}
% \label{rotating}
% 
% The \package{rotating} package\cite{rotating} offers the floating
% environments \texttt{sideways\-figure} and \texttt{sideways\-table}
% which are just like normal figures and tables but rotated by 90 degree.
% Furthermore they always use a full page on their own.
% 
% \iffalse

% 
% \subsection{The \package{sidecap} package}
% \label{sidecap}
% 
% \NEWdescription{v3.0b}
% The \package{sidecap} package\cite{sidecap} offers the floating
% environments |SCfigure| and |SCtable| which are like normal figures
% and tables but the caption will be put \emph{beside} the contents.
% 
% The \package{sidecap} package offers it's own options for justification.
% If set, they will override the one specified with the caption option
% |justification=| for captions beside their contents.
%
% \DescribeMacro{listof=}
% Using the \package{sidecap} package you will probably notice that
% suppressing the entry in the list of figures or tables with
% |\caption[]{|\ldots|}| won't work inside these environments.
% This is caused by the implementation design of the \package{sidecap}
% package, but you can use |\captionsetup{listof=false}| inside the
% figure or table as an alternative here.
% 
% \ifx\SCfigure\undefined

% \section{Compatibility to older versions}
% \label{compatibility}
% 
% \subsection{The \thispackage\ package version $1.x$}
% 
% This version of the \thispackage\ package still supports the old options
% and commands provided by the version $1.x$ 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 commands and how
% they have been replaced within this version of the \thispackage\ package:
% 
% {\small\begin{longtable}{ll}
% \thispackage\ \version{1.x} & \thispackage\ \version{3.x}\\
% \hline
% \endhead
% |normal|        & |format=plain|\\
% |hang|          & |format=hang|\\
% |isu|           & |format=hang|\\
% |center|        & |justification=centering|\\
% |centerlast|    & |justification=centerlast|\\
% \iffalse
% |anne|          & |justification=centerlast|\\
% \fi
% |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{longtable}}
% 
% Beside the options for setting up the desired font there were also
% the commands |\captionsize| resp.~|\captionfont| and |\captionlabelfont|
% who could be redefined with |\renewcommand| 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{\Section{margins}{Margins and further paragraph options}}
% 
% 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 the \thispackage\ package 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[, \Section*{misc}{Useful stuff}, and
%                 \Section*{float}{The \package{float} package}]
% 
% \subsection{The \package{caption2} package version $2.x$}
% 
% 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 the
% \thispackage\ package 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:
% 
% {\small\begin{longtable}{ll}
% \package{caption2} \version{2.x} & \thispackage\ \version{3.x}\\
% \hline
% \endhead
% |flushleft|   & |justification=raggedright|\\
% |flushright|  & |justification=raggedleft|\\
% |oneline|     & |singlelinecheck=on|\\
% \end{longtable}}
% 
% 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{\Section{margins}{Margins and further paragraph options}}
% 
% Setting an indention was done in \version{2.x} with
% \begin{quote}
%   |\captionstyle{indent}|\\
%   |\setlength\captionindent{|\ldots|}|\quad.
% \end{quote}
% This is now done with
% \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
% |\captionsetup{|\discretionary{}{}{}|singlelinecheck=|\discretionary{}{}{}|off}|
% resp.
% |\captionsetup{|\discretionary{}{}{}|singlelinecheck=|\discretionary{}{}{}|on}|.
% \See{\Section{justification}{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 the \thispackage\ package. (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
% find appropriate options and commands instead.
% 
% \iffalse
% ... (some examples)
% \fi
% 
% The \version{2.x} option |ignoreLTcapwidth| do not have a replacement, too.
% But in most cases you can simply drop using that option because
% in this version of the \thispackage\ package the value of |\LTcapwidth|
% will be ignored anyway (unless you set it to a different value than the
% default one).

% \changes{v3.0l}{2007/01/20}{Usage of \cs{PackageError} replaced by \cs{caption@error}}
%
% The \package{caption} package consists of two parts -- the kernel
% (|caption3.sty|) and the main package (|caption.sty|).
%
% The kernel provides all the user commands and internal macros which are
% necessary for typesetting captions and setting parameters regarding these.
% While the standard \LaTeX\ document classes provides an internal command
% called |\@makecaption| and no options to control its behavior (except the
% vertical skips above and below the caption itself), we provide similar
% commands called |\caption@make| and |\caption@@make|, but with a lot of
% options which can be selected with |\captionsetup|.
% Loading the kernel part do not change the output of a \LaTeX\ document
% -- it just provides functionality which can be used by \LaTeXe\ packages
% which typesets captions, like the \package{caption} package or the
% \package{subfig} package.
%
% The \package{caption} package itself redefines the \LaTeX\ commands

% Mapping the appropriate internal commands (like |\LT@makecaption| or

% \iffalse
% (This is a more straight-ahead implementation, but it only works with v1.3
%  now, so v1.2 is no longer supported. The old code including documentation
%  can be found in caption-30f-050530.zip)
% \fi
%
% 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.)
% \end{itemize}
%
% So our main goal is to re-define |\float@caption| so our macro
% |\caption@@make| will be used instead of |\@fs@capt|.
%
% To allow different caption styles for different float styles we will also
% determine the current float style (e.g. `ruled') at run time and select
% a caption style (and additional settings) with the same name, if defined.
%
% \begin{macro}{\caption@setfloatposition}
%  First of all we provide a macro which converts |\@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 the \package{caption} package (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}
\def\caption@setfloatposition{%
  \caption@setposition{\@fs@iftopcapt t\else b\fi}}

%
%    \begin{macrocode}
\caption@ifpackage{float}{@float@setevery}{%
  \caption@Info{float package v1.3 (or newer) detected}%
%    \end{macrocode}
%
% Since |\float@caption| puts the float contents into a savebox we need
% a special version of |\captionof| which `unfolds' this box afterwards,
% so the caption actually gets typeset. Furthermore we have to typeset
% the spacing above and below the caption for ourself, since this space is
% not part of the box.
%
% Please note that this version of |\captionof| only works \emph{outside}
% floating environments defined with the float package, so for example
% a |\captionof{Program}| used within a `standard' |figure| or a
% |minipage| will work fine, but not within a re-styled |figure| or
% an |Example| environment defined with |\newfloat|.
% (We don't check for this so you'll get wired errors if you try to do so!)
%
% \begin{macro}{\caption@of@float}
%  Usually no special action is necessary, so we define |\caption@of@float|
%  to |\@gobble|. We will redefine it later on to |\@firstofone| to activate
%  the code which `unfolds' the savebox.

%
%  \LaTeX{} and most packages use |\|\meta{type}|name|

%  |\figurename| will usually contain the name of the floating environment
%  |figure|:
%  \begin{quote}
%    |\newcommand\figurename{Figure}|
%  \end{quote}
%
%  But the \package{float} package don't follow this naming convention,

%    \end{macrocode}
%
%  Both |\newfloat| and |\restylefloat| save the \emph{actual} definition of
%  |\@caption| or |\float@caption| in |\@float@c@|\meta{captype} with |\let|
%  (instead of using |\def|), so redefinitions of |\@caption| (and of course
%  our redefinition of |\float@caption|) will never been used if the
%  |\newfloat| or |\restylefloat| command takes place in front of the
%  redefinitions provided by the \package{caption} or other packages like the
%  \package{hyperref} package.
%
%  So here we determine if the user has used |\restylefloat| or
%  |\restylefloat*| and bring |\@float@c@|\meta{captype} up-to-date.
%  This is quite easy: If |\@float@c@|\meta{captype} is the same as the
%  original or our own definition of |\float@caption|, the user has used
%  |\restylefloat| (and |\float@caption| should be used), otherwise
%  we assume he has used |\restylefloat*| (and |\@caption| should be used).
%  (This test will fail if some other package re-defines |\float@caption|,
%  too, so we have to assume that we are the only one.)
%
%    \begin{macrocode}
    \expandafter\let\expandafter\caption@tempa\csname @float@c@#1\endcsname
    \ifx\caption@tempa\float@caption
    \else\ifx\caption@tempa\@caption
    \else\ifx\caption@tempa\caption@@float
      \caption@Info{\protect\@float@c@#1\space := \protect\float@caption}%
      \expandafter\let\csname @float@c@#1\endcsname\float@caption
    \else
      \caption@Info{\protect\@float@c@#1\space := \protect\@caption}%
      \expandafter\let\csname @float@c@#1\endcsname\@caption
    \fi\fi\fi
%    \end{macrocode}
%
%  If the floating environment is defined with |\newfloat| or |\restylefloat|
%  (and \emph{not} with |\restylefloat*|), |\@float@c@|\meta{type}
%  will now be identical to |\float@caption|.
%
%    \begin{macrocode}
    \expandafter\ifx\csname @float@c@#1\endcsname\float@caption
%    \end{macrocode}
%
%  First of all we set the caption position to it's proper value.
%  (See above definition of |\caption@setfloatposition|)
%
%    \begin{macrocode}
      \caption@setfloatposition
%    \end{macrocode}
%
%  Now we'll have to determine the current float style.
%  This is not so easy because the only hint provided by the \package{float}
%  package is the macro |\fst@|\meta{float type} which points to the macro
%  which represents the float style.
%  So for example after
%  \begin{quote}
%    |\floatstyle{ruled}|\\
%    |\newfloat{Program}{tbp}{lop}|
%  \end{quote}
%  |\fst@Program| will be defined as
%  \begin{quote}
%    |\def\fst@Program{\fs@ruled}|\quad.
%  \end{quote}
%
%  So here is what we do: We copy |\fst@|\meta{float type} to |\caption@fst| and
%  make it a string so we can gobble the first four tokens (= |\fs@|), so only the
%  the name of the float style is left.
%
%    \begin{macrocode}
      \expandafter\let\expandafter\caption@fst\csname fst@#1\endcsname
      \edef\caption@fst{\noexpand\string\expandafter\noexpand\caption@fst}%
      \edef\caption@fst{\noexpand\@gobblefour\caption@fst}%
%     \edef\caption@fst{\caption@fst}%
%    \end{macrocode}
%
%  |\caption@fst| now contains the float style (e.g. `ruled')
%  so we can use it to set the corresponding style (if defined) and additional options.
%
%    \begin{macrocode}
      \caption@setstyle*\caption@fst

% 
% When the \package{hypcap} package is used the following problems occur:
% \begin{enumerate}
%   \item The \package{hypcap} package uses |\capstart|, |\hc@caption|, and
%   |\hc@@caption| instead of |\caption| and |\@caption|.
%   So we have to patch these macros, too.
%   \item |\caption| will be saved to |\hc@org@caption| when the
%   \package{hypcap} package is loaded.
%   We have to change this so our definition of |\caption| will always be
%   used.
%   \item Both, |\capstart| and |\hc@@caption|, call |\hyper@makecurrent|.
%   But since we offer |\ContinuedFloat| the float counters could have changed
%   between these both calls! So we fix this by saving the \package{hyperref}
%   reference (= |\@currentHref|) in |\capstart| and restoring it later on in
%  |\hc@@caption|.
%   \par{\small (This also fixes the problem that \package{hypcap} does not
%   work if |\Hy@hypertexnamesfalse| is set.\footnote{This issue was fixed
%   in \package{hypcap} \version{1.6}} This come in handy; we set
%   it locally to avoid duplicated \package{hyperref} labels which could
%   occur if |\ContinuedFloat| will be used.)}
%   \item |\capstart| will call |\H@refstepcounter| to increase the float
%   number. This collides with a following |\ContinuedFloat|, too, so we have
%   to move this call from here to |\caption|. (Since we set
%   |\Hy@hypertexnamesfalse| we can do this without problems.)

%    \begin{macrocode}
    \let\hc@org@caption\caption
%    \end{macrocode}
%  Since we don't know the float counter yet (it could be changed with

%  not be used and |\Hy@hypertexnamesfalse| is set, so unique
%  \package{hyperref} labels will be generated by the original

%  (This would not be necessary if \package{hypcap} would do this inside
