+% \begin{abstract}
+% This package redefines environment `theindex' of package \xpackage{index},
+% if a class from KOMA-Script is loaded. Also option \xoption{idxtotoc}
+% is supported. Index preambles can be given either by means of package
+% \xpackage{index} or via the interface provided by KOMA-Script.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{Documentation}
+%
+% Package \xpackage{index}, written by David M.\ Jones, detects
+% the standard classes |article|, |report|, and |book|. It
+% redefines environment `theindex' for its needs.
+% However, it does not know other classes such as KOMA-Script.
+% This package closes the compatibiliy gap between KOMA-Script's
+% classes and package \xpackage{index}.
+%
+% Environment |theindex| is redefined to support both package
+% \xpackage{index} and KOMA-Script's classes. Thus both
+% the prologe of package \xpackage{index} and the preamble
+% of KOMA-Script's classes are available. Also class option |idxtotoc|
+% of KOMA-Script is supported.
+%
+% \subsection{Usage}
+%
+% The package \xpackage{scrindex} is loaded without options:
+%\begin{quote}
+%\begin{verbatim}
+%\usepackage{scrindex}
+%\end{verbatim}
+%\end{quote}
+%
+% It loads package \xpackage{index} and requests version 2004/01/20
+% or later. \LaTeX's package interface allows multiple calls
+% of the same package. The package is loaded at its first
+% package loading command. At later times \LaTeX\ only checks
+% options and a requested version date. Therefore it does not harm
+% to add |\usepackage{index}| before or after |\usepackage{scrindex}|.
+%
+% Also the class does not matter. Environment |theindex| is only
+% redefined for a supported class:
+% \begin{itemize}
+% \item |scrartcl|
+% \item |scrreprt|
+% \item |scrbook|
+% \end{itemize}
+%
+% \subsection{Preambles}
+%
+% Both the prologue of package \xpackage{index} and the preamble
+% of KOMA-Script's classes are supported. The position depends on
+% the class.
+%
+% \subsubsection{Class \xclass{scrartcl}}
+%
+% \begin{macrocode}
+%<*example1>
+\documentclass{scrartcl}
+\usepackage{scrindex}
+\setindexpreamble{Preamble of \texttt{scrartcl}\dotfill EOL}

+\index{first}
+\index{section}
+\printindex[default]%
+ [Prologue of package \texttt{index}\dotfill EOL]%
+\end{document}
+%</example1>
+% \end{macrocode}
+% The prologue of package \xpackage{index} is first set straight
+% after the section title spanning both columns.
+% Then the preamble of KOMA-Script follows
+% in the first left column.
+%
+% \medskip
+% \begin{quote}

+\index{first}
+\index{chapter}
+\printindex[default]%
+ [Prologue of package \texttt{index}\dotfill EOL]%
+\end{document}
+%</example2>
+% \end{macrocode}
+% The order of the two preambles are different for the classes
+% \xclass{scrreprt} and \xclass{scrbook}. First KOMA-Script's
+% chapter preamble is set, then the prologue of package \xpackage{index}
+% follows. Both are set spanning both columns.

+%
+% \section{Installation}
+%
+% \subsection{Download}
+%
+% \paragraph{Package.} This package is available on
+% CTAN\footnote{\url{http://ctan.org/pkg/scrindex}}:
+% \begin{description}
+% \item[\CTAN{macros/latex/contrib/oberdiek/scrindex.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/oberdiek/scrindex.pdf}] Documentation.
+% \end{description}
+%
+%
+% \paragraph{Bundle.} All the packages of the bundle `oberdiek'
+% are also available in a TDS compliant ZIP archive. There
+% the packages are already unpacked and the documentation files
+% are generated. The files and directories obey the TDS standard.
+% \begin{description}
+% \item[\CTAN{install/macros/latex/contrib/oberdiek.tds.zip}]
+% \end{description}
+% \emph{TDS} refers to the standard ``A Directory Structure
+% for \TeX\ Files'' (\CTAN{tds/tds.pdf}). Directories
+% with \xfile{texmf} in their name are usually organized this way.
+%
+% \subsection{Bundle installation}
+%
+% \paragraph{Unpacking.} Unpack the \xfile{oberdiek.tds.zip} in the
+% TDS tree (also known as \xfile{texmf} tree) of your choice.
+% Example (linux):
+% \begin{quote}
+% |unzip oberdiek.tds.zip -d ~/texmf|
+% \end{quote}
+%
+% \paragraph{Script installation.}
+% Check the directory \xfile{TDS:scripts/oberdiek/} for
+% scripts that need further installation steps.
+% Package \xpackage{attachfile2} comes with the Perl script
+% \xfile{pdfatfi.pl} that should be installed in such a way
+% that it can be called as \texttt{pdfatfi}.
+% Example (linux):
+% \begin{quote}
+% |chmod +x scripts/oberdiek/pdfatfi.pl|\\
+% |cp scripts/oberdiek/pdfatfi.pl /usr/local/bin/|
+% \end{quote}
+%
+% \subsection{Package installation}
+%
+% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting
+% \docstrip\ archive. The files are extracted by running the
+% \xfile{.dtx} through \plainTeX:
+% \begin{quote}
+% \verb|tex scrindex.dtx|
+% \end{quote}
+%
+% \paragraph{TDS.} Now the different files must be moved into
+% the different directories in your installation TDS tree
+% (also known as \xfile{texmf} tree):
+% \begin{quote}
+% \def\t{^^A
+% \begin{tabular}{@{}>{\ttfamily}l@{ $\rightarrow$ }>{\ttfamily}l@{}}

+% \end{quote}
+% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
+% TDS installing feature, then some files can already be in the right
+% place, see the documentation of \docstrip.
+%
+% \subsection{Refresh file name databases}
+%
+% If your \TeX~distribution
+% (\teTeX, \mikTeX, \dots) relies on file name databases, you must refresh
+% these. For example, \teTeX\ users run \verb|texhash| or
+% \verb|mktexlsr|.
+%
+% \subsection{Some details for the interested}
+%
+% \paragraph{Attached source.}
+%
+% The PDF documentation on CTAN also includes the
+% \xfile{.dtx} source file. It can be extracted by
+% AcrobatReader 6 or higher. Another option is \textsf{pdftk},
+% e.g. unpack the file into the current directory:
+% \begin{quote}
+% \verb|pdftk scrindex.pdf unpack_files output .|
+% \end{quote}
+%
+% \paragraph{Unpacking with \LaTeX.}
+% The \xfile{.dtx} chooses its action depending on the format:
+% \begin{description}
+% \item[\plainTeX:] Run \docstrip\ and extract the files.
+% \item[\LaTeX:] Generate the documentation.
+% \end{description}
+% If you insist on using \LaTeX\ for \docstrip\ (really,
+% \docstrip\ does not need \LaTeX), then inform the autodetect routine
+% about your intention:
+% \begin{quote}
+% \verb|latex \let\install=y\input{scrindex.dtx}|
+% \end{quote}
+% Do not forget to quote the argument according to the demands
+% of your shell.
+%
+% \paragraph{Generating the documentation.}
+% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
+% the documentation. The process can be configured by the
+% configuration file \xfile{ltxdoc.cfg}. For instance, put this
+% line into this file, if you want to have A4 as paper format:
+% \begin{quote}
+% \verb|\PassOptionsToClass{a4paper}{article}|
+% \end{quote}
+% An example follows how to generate the
+% documentation with pdf\LaTeX:
+% \begin{quote}
+%\begin{verbatim}
+%pdflatex scrindex.dtx
+%makeindex -s gind.ist scrindex.idx
+%pdflatex scrindex.dtx
+%makeindex -s gind.ist scrindex.idx
+%pdflatex scrindex.dtx
+%\end{verbatim}
+% \end{quote}
+%
+% \section{Catalogue}
+%
+% The following XML file can be used as source for the
+% \href{http://mirror.ctan.org/help/Catalogue/catalogue.html}{\TeX\ Catalogue}.
+% The elements \texttt{caption} and \texttt{description} are imported
+% from the original XML file from the Catalogue.
+% The name of the XML file in the Catalogue is \xfile{scrindex.xml}.
+% \begin{macrocode}
+%<*catalogue>
