% \maketitle
% \begin{abstract}
%   The main purpose of package \textsf{tocbasic} is to provide features for
%   authors of classes and packages to create own tables or lists of contents
%   like the list of figures and the list of tables and thereby allow other
%   classes or packages some types of control over these. For examples package
%   \textsf{tocbasic} delegates language control of all these tables and lists
%   of contents to package \textsf{babel}. So automatic change of language
%   will be provided inside all these tables and lists of contents. Using
%   \textsf{tocbasic} will exculpate authors of classes and packages from
%   implementation of such features.
%
%   \KOMAScript{} itself uses \textsf{tocbasic} not only for the table of
%   contents but also for the already mentioned lists of figures and tables.

% \section{Implementation}
% \label{sec:implementation}
%
% All macros with prefix \texttt{tb@} or \texttt{@} are internal macros and
% should not be used by package and class authors. Macros with prefix
% \texttt{tocbasic@} are internal macros, that may be used by class and
% packages authors. Macros without \texttt{@} are interface macros and may be
% used by class and package authors and users.
%
% Note: Parts of the implementation of package \textsf{tocbasic} are
% out-sourced into file \texttt{scrkernel-tocbasic.dtx}.
%
% \iffalse
%<*package>
% \fi
%
% \subsection{Options}
% \label{sec:options}
%
% There are no options because the package should be used by class and package
% authors not by users. So the package will be loaded using
% \cs{RequiresPackage}. Using different options by different packages would
% result in an option clash.
%    \begin{macrocode}
%<*option>
\ProcessOptions\relax
%</option>
%    \end{macrocode}
%
%
% \subsection{Required Packages}
% \label{sec:packages}
%
% Package \textsf{scrbase} is needed to process all macro options. As long as
% no package options are provided, the \texttt{body}-run is early enough to
% load it.
%    \begin{macrocode}
%<*body>
\RequirePackage{scrbase}
%</body>
%    \end{macrocode}
% We load it after processing the options, because we don't need it for
% processing options.
%
%
%
% \subsection{Unwanted Packages}
% \label{sec:unpackages}
%
% There are packages, that are not recommended to be used together with
% \textsf{tocbasic}:
%    \begin{macrocode}
%<*body>
%    \end{macrocode}
% \begin{description}
% \item[\textsf{multitoc}:] This package implements multi-column ToCs using
%   \textsf{multicol}. Unfortunately there is a bug in that package, that
%   disables all extensions but \texttt{toc}, \texttt{lof} and \texttt{lot} and
%   even these if the corresponding option has not been set.
%    \begin{macrocode}

% \subsection{Having a List of All Tocs}
% \label{sec:listoftocs}
%
% If we have a list of all toc-files we may do commands for all
% toc-files. Somethimes it may be usefull to known the package, that created
% the toc-file, so this information will be stored additionally.
%
% \begin{macro}{\tb@listoftocs}
% This is the list of toc-files. The list will be:
% \begin{quote}
%   \cs{do}\marg{extension}\marg{class or
%   package}\cs{do}\marg{extension}\marg{class or package}\dots
% \end{quote}
% With this, adding and processing the list will be very fast but removing
% an element will be very slow.
%
% The initial state of the list will be \emph{empty}.
