% \maketitle
% \begin{abstract}
% From 2002 up to end of 2021 \cls*{scrdoc} was the class, that has been used
% for the sources of \KOMAScript{} and several other packages of the
% \KOMAScript{} author. This class was more or less a ugly hack to use a
% modified and extended version of \cls{ltxdoc}, the source documentation
% class of The \LaTeX{} Team. There has been advisement to redesign this
% class for years, but as changing the source documentation class is more a
% work of month than of days, I've always put it on the back burner.
%
% In January 2022, The \LaTeX{} Team switched over from \pkg{doc} version 2 to
% version 3. The new version is compatible on user interface level, but as
% expected not on implementation level. So the extensions made in \cls*{scrdoc}
% result in several error messages. For such cases The \LaTeX{} Team has the
% fallback solution to use an old \pkg{doc}. But this can only be used, if you
% load \pkg{doc} yourself using either |\usepackage| or
% |\RequirePackage|. If class \cls{ltxdoc} is used, the fallback does not
% exist.
%
% A first workaround for \cls*{scrdoc} was a typical hacker solution, that
% forces \cls{ltxdoc} to use an old version of \pkg{doc} and to fix the
% resulting issues after loading \cls{ltxdoc}. But this does only work as long
% as new releases of \cls{ltxdoc} are compatible with the \pkg{doc} release of
% 2021.
%
% So in January 2022, it was really time for a new \KOMAScript{} source
% documentation class. This new class does not use internal commands of
% \cls{ltxdoc} any longer but uses the extended interface of \pkg{doc} version
% 3 to define further documentation items.
% \end{abstract}

%
% \section{Prerequisites}
% \label{sec:prerequisites}
%
% Class \cls*{koma-script-source-doc} needs at least class \cls{ltxdoc} version
% 2.1d which depends on package \pkg{doc} version 3, because it used several
% of the new features of that \pkg{doc} release. This is part of
% \texttt{latex-base-dev} 2022-06-01 pre-release~1 distributed on
% \href{https://www.ctan.org}{CTAN} on 14th January 2022 and therefore will be
% part of \LaTeX{} 2022-06-01. If you still use an older \LaTeX{} you cannot
% use class \cls*{koma-script-source-doc}.
%
%
% \section{Basic Settings}
% \label{sec:basicsettings}
%
% For \KOMAScript{} we use some basic settings:
% \begin{itemize}
% \item Generation of the indexing of new commands is generally enabled by
%   \pkg{doc}. We do not use \cs{EnableCrossrefs}, because this would not
%   allow to disable this feature using \cs{DisableCrossrefs}. It is also
%   recommended not to generally use \cs{EnableCrossrefs} in the
%   \file{dtx}-file.
% \item We use \cs{CodeLineIndex} to have code line numbers for the
%   indexing. This could be problematic sometimes. In this case, you should
%   use \cs{PageIndex} and \cs{CodelineNumbered} to use page numbers in the
%   index but nevertheless add line numbers to the code.
% \item For \KOMAScript{} code we usually record the changes. So we use
%   \cs{RecordChanges} and option \opt{reportchangedates} This is the only
%   real changelog we do. However, if your \file{dtx}-file contains the user
%   manual, it would be recommended to list the main changes like new features
%   and incompatibilities as a section either at the very beginning or the end
%   of the user manual.
% \item \DescribeOption{indexlatex} For \KOMAScript{} sources I do not like to
%   index all the \LaTeX{} interface commands and internal
%   commands\footnote{This does only work for those \LaTeX{} macros, already
%   internally listed. The list should be generated automatically after each
%   \LaTeX{} release. Unfortunately, currently it is build step by step with
%   every new \KOMAScript{} release instead.}. You can changes this, using
%   option \opt{indexlatex}. You can also use explicit \opt{indexlatex=false}
%   to again not index the \LaTeX{} kernel macros.
% \item You also should use \cs{GetFileInfo}\marg{dtx-filename} to get
%   information like \cs{filedate} and \cs{fileversion} from the
%   \cs{ProvidesFile} command of the \file{dtx}-file. Sometimes it may even be
%   better to use the generated package or class as argument.
% \end{itemize}
%
%
% \section{Simple Formatting Commands}
% \label{sec:simpleformatting}
%
% \DescribeCommand{\file}
% \DescribeCommand{\opt}
% \DescribeCommand{\optvalue}
% \DescribeCommand{\env}
% \DescribeCommand{\cnt}
% \DescribeCommand{\fnt}
% \DescribeCommand{\len}
% \DescribeCommand{\var}
% \DescribeCommand{\plen}
% \DescribeCommand{\pstyle}
% \DescribeCommand{\dhook}
% There are some very simple formatting commands. They all expect one
% mandatory argument \meta{object name}. The default formatting is to use
% \cs{texttt}. The commands are mentioned for the name of a file, option,
% value of an option, environment, \LaTeX{} counter, font, length (either
% dimension or skip), variable (usually \KOMAScript{} variables used by
% \cls*{scrlttr2} or \pkg*{scrletter}), pseudo-length (of \cls*{scrlttr2} or
% \pkg*{scrletter}), page style, or do hook.
%
% \DescribeCommand{\cls}
% \DescribeCommand{\pkg}
% The commands:
% \begin{quote}
%   \cs{cls}\oarg{hyper link}\marg{package name}\hfill and\hfill
%   \cs{pkg}\oarg{hyper link}\marg{class name}
% \end{quote}
% do not only print the name of a class or package, but also generate a hyper
% link. For this the commands have a first optional argument. If this is
% empty, no link will be generated. If it is not empty, it has to be the
% link. If it is not used an automatic package link to the
% \href{https://www.ctan.org/pkg}{CTAN} package with the same name will be
% generated. There are also star variants \cs{cls*} and \cs{pkg*}, that do not
% produce any link. For links with special characters like \texttt{\char`\#}
% it is recommended to use \cs{href} and the star variant.

% \cls{ltxdoc} to use \KOMAScript{} class \cls*{scrartcl} instead of standard

% \subsection{Documentation Items}
% \label{sec:documentationitems}
%
% \KOMAScript{} has several additional items beside macros and environments.
% The old \cls*{scrdoc} class provides macros, environments, options, lengths,
% counters, variables and fonts. But now we also distinguish internal macros
% vs. users commands and internal lengths vs. user lengths. In this
% documentation we additionally provide documentation items.
