+% \section*{This package is obsolete!}
+%
+% The \package{caption2} package used to be an experimental side-version of
+% the regular \package{caption} package and has been superseed by the new
+% release of the regular \package{caption} package version \mbox{3.0} in
+% December 2003.
+%
+% \package{caption2} is still some kind of supported, that means it will be
+% part of future releases and bugs will still be fixed, so existing documents
+% using this package will still compile. But I will \emph{not} answer
+% questions about this package anymore except questions on migrating to the
+% regular version of the \package{caption} package. And it will \emph{not} be
+% adapted or enhanced in the future.
+%
+% So please don't use this package for new documents. It's old, it's obsolete
+% and it starts to begin smell bad!
+%
+% Please ignore all hints in books or other documents which try to tell you
+% that the \package{caption2} package should be used instead of the
+% \package{caption} package -- these hints are outdated since December 2003.
