% This package adapts the \pkg{caption} package to the \KOMAScript\ document classes.

%
% \section*{User manual}
%
% This document is describing the code implementation only.
% The user documentation can be found in
% \nopagebreak\begin{quote}

%
% \section*{State of this package}
%
% Please note that the last major revision of this code was done in the year 2007,
% afterwards the \KOMAScript\ support was adapted to changes in the \pkg{caption} package only.
%
% So nearly everything which has changed in the caption support of \KOMAScript\ since 2007 is not reflected here.
% (So for example |\set|\-|cap|\-|dyn|\-|width| is not emulated yet etc.)
