% \begin{abstract}
% \filename{} is not only used for the code of all \KOMAScript{} classes and
% most of the \KOMAScript{} packages. It is also used by most of the
% installation drivers (\file{ins}-files) for the definition of
% \KOMAScript{} version.

% \section{User Manual}
%
% You can find the user documentation of the commands implemented here in the
% \KOMAScript{} manual, either the German \file{scrguide-de.pdf} or the
% English \file{scrguide-en.pdf}.

% \begin{command}{\KOMAScriptVersion}
% \changes{v2.95}{2002/06/25}{added}
% The main purpose of this command it to prevent mixture of files of
% different \KOMAScript{} versions. But users can also use this command to
% detect \KOMAScript{}. It is added to the classes and most of the packages
% by the installation drivers. This is done using \file{scrdocstrip.tex} and
% additionally loading this file.
% \begin{macro}{\@CheckKOMAScriptVersion}
% \changes{v2.95}{2002/06/25}{added}
% \changes{v3.42}{2024/04/17}{command is defined only once but \pkg{expl3}
% hard}
% \changes{v3.42}{2024/04/17}{command is no longer defined in \file{clo}
% or \file{lco} files}
% Depending on \cs{KOMAScriptVersion} already defined or not, the existing
% definition is compared with the version here or \cs{KOMAScriptVersion} is
% newly and globally defined. This has to work not only in class or package
% files, but also in document files. So \cs{makeatletter} inside a group is
% needed for the internal macros. Additionally a guard \texttt{ignorethis} is
% used, to avoid adding code, that is needed only for the installation driver,
% also to classes or packages. Note, the version check is also done in
% \file{clo} or \file{lco} files, but the macros \cs{@CheckKOMAScriptVersion}
% and \cs{@@CheckKOMAScriptVersion} are not defined in those, because those
% files should not always be loaded by \KOMAScript{} classes or packages,
% which would already define the command.
