%
% \begin{abstract}
% \Thispackage\ 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 provide 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, for example the \package{caption} and
% \package{subfig} packages.
%
% \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.

% \begin{macro}{\@nameundef}
%  This is the opposite to |\@namedef| which is offered by the \LaTeX\ kernel.

%  (using \cs{edef} instead of \cs{xdef}).

% which determine if a value is given (and therefore should be treated as
% our option) or not (and therefore should be ignored by us).\footnote{%^^A
% This problem was completely solved due a change of \cs{caption@ProcessOptions}

%  Please forget about the optional argument, it was never working well, is
%  incompatible to the \package{subfig} package, but is still there for
%  compatibility reasons.
%  \Note{The definition of \cs{ContinuedFloat} itself is compatible
%   to the one inside the \package{subfig} package, except for the
%   starred variant and the optional argument.}
%  When the \package{hyperref} package is used we have the problem
%  that the usage of |\ContinuedFloat| will create duplicate
%  hyper links -- |\@currentHref| will be the same for the main float and
%  the continued ones. So we have to make sure unique labels and references
%  will be created each time. We do this by extending |\theHfigure| and
%  |\theHtable|, so for continued floats the scheme
%  \begin{quote}\meta{type}|.|\meta{type \#}|\alph{|\meta{continued \#}|}|\end{quote}
%  will be used instead of
%  \begin{quote}\meta{type}|.|\meta{type \#}\quad\quad.\end{quote}

% \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.)

%  |\@float@setevery|\marg{float type} is provided by the \package{float}

%  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

%  \begin{quote}
%    |\newcommand\figurename{Figure}|
%  \end{quote}
%  But the \package{float} package doesn't follow this common naming
%  convention:
%  For floats defined with |\newfloat| it uses |\fname@|\meta{type} instead,

%  So we have to map the \package{float} package name to the common one here.\par

%  |\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
