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. +% \end{abstract} +% +% \StopEventually{} +% \clearpage +% \tableofcontents +% +% \iffalse +%
