+%
+% \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.

+% \package{arabtex} re-defines \cs{@gobble} as not-long so the packages of the

+% Since the \package{subfig} package is not maintained anymore,
+% we have to make several adaptions to \thispackage~\version{1.1} here.
+% Please note that we only support the version $1.3$ of the \package{subfig} package here.
+% So older versions do not work with this version of \thispackage, and newer
+% versions are expected to be adapted.
