% \section*{THIS PACKAGE IS OBSOLETE!}
%
% The \package{caption2} package used to be an experimental side-version of
% the regular \package{caption} package. It was made public as beta test version
% without documentation in 1995 because of the strong demand for new features and
% adaptations to other packages like the \package{longtable} and
% \package{subfigure} one.
%
% But within the next years I found no time to reintegrate some of the
% well-tried features into the regular \package{caption} package. So I
% decided to release a version $2.1$ of the \package{caption2} package in 2002
% instead, which included some minor bug fixes and adaptations to the new
% version $2.1$ of the \package{subfigure} package. Furthermore I started
% to write a documentation for this package, but unfortunately did not get
% very far with this\ldots
%
% In 2003 I finally found some (more) 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% It was released in December 2003 and superseded the neglected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.
%
% {\small (In parallel, Steven Cochran released the \package{subfig} package which
% superseded the \package{subfigure} package.)}
%
% So please don't use this package for new documents. It's old, it's obsolete
% and it starts to begin smell bad!
% Please ignore all hints in books or other documents which try to tell you
% that the \package{caption2} package should be used instead of the
% \package{caption} package -- these hints are outdated since December 2003.

%
% \section*{How to migrate to the regular \package{caption} package?}
%
% Usually replacing \package{caption2} by \package{caption} is sufficient
% because the \package{caption} package emulates most of the options and
% commands offered by the \package{caption2} package.
% If you get some errors or wired results afterwards, please take a closer
% look at the \package{caption} package documentation which will hopefully
% help you clearing these problems. You will also find a section called
% `Compatibility to older versions' there which should help you with the
% migration process.
% If all this should fail you can write me an e-mail asking for help.
%
% \section*{What will happen to this package?}
%
% The \package{caption2} package is still some kind of supported, that means
% it will be part of future releases of the \package{caption} package bundle,
% and bugs will still be fixed so existing documents using this package will
% still compile.
% But it will \emph{not} be enhanced in the future.
%
% This means migrating to the actual \package{caption} package should not be
% necessary for old documents -- they should still compile fine as they are.
% If not, please don't hesitate to write me an e-mail asking for
% maintainance.

% the 2nd and 3rd are the caption label and text.
%
% \textsf{caption2} has the goal not to modify the output just by
% loading it (without options), therefore we have to be tricky here to
% support \cs{@fs@cfont} which is in fact the same as our \cs{captionlabelfont}.
% So we test if a \cs{captionlabelfont} has been set by the user -- if not
% \cs{@fs@cfont} will be used, otherwise \cs{captionlabelfont}.

%
% \begin{macro}{\floatc@plain}
% Now we can redefine the caption code of the \textsf{float} package.

% \begin{macrocode}

% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\floatc@ruled}
% The support of the \texttt{ruled} float type is a little
% more complex. First we define a caption style `ruled' so the end-user
% can change this caption style afterwards. If the (obsolete) option
% `ruled' is set, we define it in a \textsf{caption} v1.x compatible way,
% otherwise we define it in a \textsf{float} compatible way.
%
% Then we redefine \cs{floatc@ruled} so the caption style `ruled' will
% be used.

% \end{macro}
%
% \begin{macro}{\caption@of}
% Typesetting captions outside floats is not so easy with redefined floats,
% because
% \begin{itemize}
% \item The caption code of the \textsf{float} package needs not only
% \cs{@captype} defined, but \cs{@fs@capt} (the command which will typeset the
% caption itself) either.
% \item The caption is only saved within a \cs{vbox}, so the \textsf{float}
% package can typeset the caption later at it's float style specific place
% (that means at top or at the bottom of the float).
% \end{itemize}
%
% Here is the new code: First we check if it's a restyled float by checking if
% \cs{fst@<floattype>} is defined. If yes, we use this command (it will define
% \cs{@fs@capt}).
% Then we execute \cs{@float@setevery}, if it exists (that means we are
% dealing with the \textsf{float} package 1.3 or newer here).
% Now comes the basic trick:
% We redefine the caption typesetting command \cs{@fs@capt}, so it will close
% the \cs{vbox}, typeset the caption outside the vbox and finally start the
% group again so the original \cs{@fs@capt} is happy with closing the group.
%
% \begin{macrocode}
\renewcommand*\caption@of[2]{\def\@captype{#2}%

\else
\PackageInfo{caption2}{longtable package v3.15 (or newer) detected}
% \end{macrocode}
%
% \begin{macro}{\LT@makecaption}
% David Carlisle was so kind to introduce a macro called
% \cs{LT@makecaption} in version 3.15 of the \textsf{longtable}
% package which typeset the caption and can be easily redefined.
%
% This is the original definition:
% \begin{quote}
% |\def\LT@makecaption#1#2#3{%|\\
% | \LT@mcol\LT@cols c{\hbox to\z@{\hss\parbox[t]\LTcapwidth{%|\\

% | \endgraf\vskip\baselineskip}%|\\
% | \hss}}}|
% \end{quote}
%
% So we do here:
% First we define a new (dummy) caption style `longtable',
% than we redefine \cs{LT@makecaption} so this style will be used.
% (Remember: |#1| is |\@gobble| in star form of |\caption|,
% and |\@firstofone| otherwise.)

%
% \begin{macro}{\setsubcapstyle}
% This sets the subcaptionstyle to a appropriate value.
%
% If \cs{ifsubcapraggedright} is undefined (it was introduced
% into v2.1 of the \textsf{subfigure} package) we define it first.
% \begin{macrocode}

% \end{macro}
%
% \begin{macro}{\caption@makesubcaption}
% \changes{v2.2c}{2008/07/01}{Bugfix: Usage of \cs{ifcaptionwidth} removed}
% This will typeset the subcaption.
% We just set all our \cs{caption}\textit{xxx} values to
% the values of \cs{subcap}\textit{xxx} and typeset the
% caption like \textsf{subfigure} within a \cs{hbox},
% but with the help of \cs{usecaptionstyle}.
%
% But this is not as easy as it seems. We typeset the caption like this:
% \begin{quote}
% |\captionfont|\\
% | {\capionlabelfont\captionlabel\captionlabeldelim}%|\\
% |\captionlabelsep\captiontext|
% \end{quote}
% Within \textsf{subfigure} 2.0 the caption will be set quite similar to:
% \begin{quote}
% |\subcapsize|\\
% | {\subcaplabelfont\captionlabel}%|\\
% |\space\captiontext|
% \end{quote}
% But within \textsf{subfigure} 2.1 this has changed to:
% \begin{quote}
% |\subcapsize|\\
% | {\subcaplabelfont\captionlabel}%|\\
% |\hskip\subfiglabelskip|\\
% | {\subcapfont\captiontext}}|
% \end{quote}
% So we have to be tricky here: We set \cs{captionlabelfont} to \cs{normalfont} plus
% \cs{subcapsize} \& \cs{subcaplabelfont}, so the font setting in \cs{captionfont}
% will not affect the caption label in subfigure captions.
%
% Note that \cs{hfil} has changed to \cs{hss} from subfigure 2.0 to 2.1,
% so we use \cs{caption@subfig@hss} instead. (We will define this later on.)
