% \date{Revision \fileversion{} of \filedate}
% \maketitle
% \begin{abstract}
%   The main purpose of package \pkg*{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
%   \pkg*{tocbasic} delegates language control of all these tables and lists
%   of contents to package \pkg{babel}. So automatic change of language
%   will be provided inside all these tables and lists of contents. Using
%   \pkg*{tocbasic} will exculpate authors of classes and packages from
%   implementation of such features.
%
%   \KOMAScript{} classes use \pkg*{tocbasic} not only for the table of
%   contents but also for the already mentioned lists of figures and tables.
% \end{abstract}

% \section{User Manual}
%
% You can find the user manuals of \pkg*{tocbasic} in the \KOMAScript{}
% manual, either the German \file{scrguide-de.pdf} or the English
% \file{scrguide-en.pdf}.

% \subsection{Caption handling}
%
% \changes{v3.46}{2025/06/10}{\pkg*{tocbasic} handles captions}
% From version 3.46 package \pkg*{tocbasic} not only supports but provides the
% caption handling that was formerly part of the \KOMAScript{} classes. This
% allows us also a (partial) redesign of the implementation. Nevertheless, we
% try to keep it compatible. When package \pkg{caption} is loaded, most of the
% features are delegated to that package.
%
% \ExplSyntaxOn
% \begin{macro}{\g_@@__caption_above_bool}
%   \ExplSyntaxOff
%   \changes{v3.46}{2025/06/13}{added}
%   The default formation for captions should above (instead of below) the
%   content. This has to be predefined, because
%   \cs{tocbasic\_define\_caption\_keys:n} does not automatically define
%   it. The initial value is \optvalue{false}.

% \begin{command}{\tocbasic_define_caption_keys:n}
%   \ExplSyntaxOff
%   \changes{v3.46}{2025/06/13}{added}
%   Allows to define the boolean looking choice options \opt{\#1captionabove}
%   and \opt{\#1captionbelow} and the choice options \opt{\#1captionposition}
%   with the three values \optvalue{top}, \optvalue{bottom} and
%   \optvalue{default}. Value \optvalue{default} resets the caption position
%   for \texttt{\#1} to the default caption position. If \texttt{\#1} is
%   empty, the default value is not defined! The code not only respects
%   package \pkg{caption} but actively supports its use. This is the main
%   reason, why it cannot use real boolean options, but needs to simulate them
%   using choice options. The code looks complicated because resetting the
%   \pkg{caption} options for floats is different for \env{figures} and
%   \env{tables} than for other floats. Also resetting \pkg{caption} options
%   of single floats needs an extra command (at least after
%   \verb|\begin{document}|).
