% \begin{abstract}
% \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.

%

%   so it can be placed above or below the float contents afterwards.

%   Instead |\@fs@capt| will be used which definition is part of the float
%   style.

%   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}

%  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

%  finally typeset the caption with skips.
%    \begin{macrocode}
      \caption@setposition{\@fs@iftopcapt t\else b\fi}%
%    \end{macrocode}

%  Determining the float style is not so easy because the only hint

%  |\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.
