% package\cite{bibtopic}.

% \section{Introduction}
% ^^A
% Suppose you want to split your literature in your document into
% parts (this can be done with the \package{bibtopic} package) and you
% want to make this split visible in the references in the document.
%
% This package loads \package{bibtopic} with the right option and then
% defines a command \cs{bibprefix} which should be used inside the
% \env{btSect} environment, whose argument is inserted before every
% reference (e.\,g. [1] becomes [\meta{prefix}1]).
%
%
% ^^A -----------------------------
%
% \section{Usage}
% ^^A
% \DescribeMacro{\bibtopic}
% Add an \mbox{\cs{usepackage\{}\package{bibtopicprefix}\texttt{\}}}
% to your document and insert the command \cs{bibprefix}\marg{prefix}
% at the start of every \env{btSect} environment.
% \begin{quote}
%\begin{verbatim}
%\begin{btSect}{adlit}
% \renewcommand{\bibprefix}{AD}
% \section{Applicable Documents}
% \btPrintCited
%\end{btSect}
%\begin{btSect}{rdlit}
% \renewcommand{\bibprefix}{RD}
% \section{Reference Documents}
% \btPrintCited
%\end{btSect}
%\end{verbatim}
% \end{quote}
% The package works of course best with bibliography styles that
% produce numerical references (like \bst{plain}).
%
%
% ^^A -----------------------------
%
% \section{Required packages}
% ^^A
% This package requires the following package:
% \begin{description}
% \item[\normalfont\package{bibtopic}\cite{bibtopic}]
% It is loaded with the right option so that all bibliographies
% are numbered indepedently.
% \item[\normalfont\package{scrlfile}\cite{scrlfile}]
% \changes{v1.10}{2006/10/22}{Use \package{scrlfile}}
% This is used internally to handle the
% \package{hyperref}\cite{hyperref} package.
% \end{description}

% \begin{macrocode}
\RequirePackage{scrlfile}
% \end{macrocode}
% We need the \package{bibtopic} package\cite{bibtopic} and we have

% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\@bibitem}
% We want to redefine \cs{\@bibitem} to add our prefix.
% To do this we need to distinguish three cases: the use of the
% \package{hyperref} package, the use of the \package{babel} package
% and the default.
%
% We handle the \package{hyperref} package by activating our code
% after \package{hyperref} with the help of \cs{AfterPackage*} from
% \package{scrlfile}.
