% \begin{abstract}
% \Thispackage\ offers (limited) customization of captions
% in floating environments such |figure| and |table|.
% \par\smallskip
% \textit{Please note:} Many document classes already have build-in options and
% commands for customizing captions.
% If these possibilities are sufficient for you, there is usually no need for
% you to use the \package{caption} package at all.
% And if you are just interested in using the command \cs{captionof}, loading
% of the very small \package{capt-of} package is usually sufficient.

% \section{Loading the package}
%
% Load this package using
% \begin{quote}
%   |\usepackage|\oarg{options}|{caption-light}|
% \end{quote}
% or
% \begin{quote}
%   |\usepackage{caption-light}|\\
%   \ldots\\
%   |\captionsetup|\marg{options}
% \end{quote}
% As opposite to the \package{caption} package only a limited set of options is
% supported by \thispackage:
% |aboveskip=|\ldots,
% |belowskip=|\ldots,
% |font=|\ldots,
% |justification=|\ldots,
% |labelfont=|\ldots,
% |labelseparator=|\ldots,
% |position=|\ldots,
% |singlelinecheck=|\ldots,
% |skip=|\ldots, and
% |textfont=|\ldots
%
% See \package{caption} package documentation for the meaning and usage of
% these options.
%
% \section{Commands}
%
% This package offers |\caption|\-|setup|, |\set|\-|caption|\-|type|, and
% |\caption|\-|of| as well.
%
% \section{Why this package?}
%
% This package offers some advantages over the \package{caption} package:
% \begin{itemize}
% \item It does not depend on correct |\hsize| for "long" captions,
% just like the original definition included in |article|, |report|, and |book|.
% \item If the caption is typeset as "short" (centered), the content of
% the caption is evaluated only once,
% just like the original definition included in |article|, |report|, and |book|.
% \item It does not re-define |\caption| and floating environments,
% therefore avoiding incompatibilities.
% \item It does not patch any other packages, therefore avoiding
% incompatibilities.
% \end{itemize}
%
% In short it's a more compatible and less troublesome variant of the
% \package{caption} package, but (much) less powerful.
