+% \subsection{ASCII-code: \texttt{datetime2-german-base-ascii.ldf}}
+% The definitions in this file use \LaTeX\ commands for non-ASCII characters.
+% It should be used if neither \hologo{XeLaTeX} nor \hologo{LuaLaTeX} are used.
+% Even if the user has loaded \sty{inputenc} with "utf8", this file should still
+% be used instead of \texttt{datetime2-german-base-utf8.ldf} as the non-ASCII
+% characters are made active in that situation and would need protecting
+% against expansion.

+    
+    
+    \begin{abstract}
+         This is the German language module for the \sty{datetime2} package. It defines a regionless style as well as variant styles ("de-DE", "de-AT" and "de-CH").
+         
+         If you want to use the settings in this module you must install it in addition to installing \sty{datetime2}.
+         If you use \sty{babel} or \sty{polyglossia}, you will need this module to prevent them from redefining \cs{today}.
+         
+         The \sty{datetime2} \opt{useregional} setting must be set to "text" or "numeric" for the language styles to be set.
+         Alternatively, you can set the style in the document using \cs{DTMsetstyle}, but this may be changed by \cs{date}\meta{language} depending on the value of the \opt{useregional} setting.

+    \addcontentsline{toc}{subsection}{Installation}
+    Extract the language definition files first:
+    \begin{enumerate}
+        \item Run \LaTeX\ over the file "datetime2-german.ins": \\
+            "latex datetime2-german.ins"
+            
+        \item Move all "*.ldf" files to "TEXMF/tex/latex/datetime2-contrib/datetime2-german/"
+    \end{enumerate}
+    Then, you can compile the documentation yourself by executing \\[\smallskipamount]
+    "lualatex datetime2-german-doc.dtx" \\
+    "makeindex -s gind.ist datetime2-german-doc.idx" \\
+    "makeindex -s gglo.ist -o datetime2-german-doc.gls datetime2-german-doc.glo" \\
+    "lualatex datetime2-german-doc.dtx" \\
+    "lualatex datetime2-german-doc.dtx" \\[\medskipamount]
+    or just use the precompiled documentation shipped with the source files. \\
+    In both cases, copy the files "datetime2-german-doc.pdf" and "README.md" to \\
+    "TEXMF/doc/latex/datetime2-contrib/datetime2-german/"
+

+        
+        \item Bernhard Waldbrunner for his merge request, which resulted in the adoption of the DD.MM.YYYY numeric date format with the Austrian numeric style in version 3.0.
+        Previous versions used the ISO format (YYYY-MM-DD) as recommended by ÖNORM~1080, which was withdrawn in May~2018.

+    \subsection{Setting up \sty{datetime2} with a language module}
+    \textit{There are several methods of loading a language module. \\ Please refer to \sty{datetime2}'s documentation for details.}
+    
+    \bigskip
+    \textbf{Variant 1:} \\
+    Set the date style explicitly by passing "german", "de-DE", "de-AT" or "de-CH" to \sty{datetime2}: \\[\smallskipamount]
+    "\documentclass{article}" \\
+    "\usepackage[german]{datetime2}" \\
+    "\begin{document}" \\
+    "\today" \\
+    "\end{document}"
+
+    \medskip
+    \textbf{Variant 2: Pick up the desired style from \sty{babel} or document class options)} \\
+    Pass the language (e.g. "german", "ngerman", "austrian", "naustrian", \dots) as an option to the \cs{documentclass} command (or \sty{babel} itself). As soon as the \opt{useregional} option is passed to \sty{datetime2}, the suitable language module is loaded: \\[\smallskipamount]
+    "\documentclass[german]{article}" \\

+    \subsection{Customization}
+    There are a number of settings provided that can be used in \cs{DTMlangsetup} to modify the date-time style. These are:
+    \begin{description}
+    	\item["dowdaysep"]%
+    	The separator between the day of week name and the day of month number.
+    
+    	\item["daymonthsep"]%
+    	The separator between the day and the month name.
+    
+    	\item["monthyearsep"]%
+    	The separator between the month name and year.
+    
+    	\item["datesep"]%
+    	The separator between the date numbers in the "numeric" styles.
+    
+    	\item["timesep"]%
+    	The separator between hours, minutes and seconds.
+    
+    	\item["datetimesep"]%
+    	The separator between the date and time for the full date-time format.
+    
+    	\item["timezonesep"]%
+    	The separator between the time and zone for the full date-time format.
+    
+    	\item["abbr"]%
+    	This is a boolean key. If "true", the month (and weekday name, if shown) is abbreviated.
+    
+    	\item["mapzone"]%
+    	This is a boolean key. If "true", the time zone mappings are applied.
+    
+    	\item["showdayofmonth"]%
+    	A boolean key that determines whether or not to show the day of the month.
+    
+    	\item["showyear"]%
+    	A boolean key that determines whether or not to show the year.
+    \end{description}
+
+    Although these keys are \textit{defined} for all variant styles, it depends on \sty{datetime2}'s configuration and the requested styles whether they're \textit{used}. More details about the \cs{DTMlangsetup} command can be found in \sty{datetime2}'s documentation.

-%\maketitle
-%
-%
-%\begin{abstract}
-% This is the German language module for the \sty{datetime2}
-% package. If you want to use the settings in this module you must
-% install it in addition to installing \sty{datetime2}. If you use
-% \sty{babel} or \sty{polyglossia}, you will need this module to
-% prevent them from redefining \cs{today}. The \sty{datetime2}
-% \opt{useregional} setting must be set to "text" or "numeric"
-% for the language styles to be set.
-% Alternatively, you can set the style in the document using
-% \cs{DTMsetstyle}, but this may be changed by \cs{date}\meta{language}
-% depending on the value of the \opt{useregional} setting.
-%\end{abstract}
-%
-%
-%
-% Currently there is a regionless style as well as variant styles ("de-DE", "de-AT" and "de-CH"). \\[\smallskipamount]
-% I'm only capable of German standard German. If I messed up anything in regards to format and/or spelling, or even a variant style with differences to the existing ones is missing, please create a feature request on GitHub or send me an e--mail. \\
-% I would be very grateful, if some examples and/or a list of the weekdays' and months' spelling is/are also provided.

-% Thanks to Jürgen Spitzmüller for his valuable advice while developing Version 2.0 of this module.

-% \section{Installation}
-% Extract the language definition files first:
-% \begin{enumerate}
-%     \item
-%     Run \LaTeX\ over the file \texttt{datetime2-german.ins}: \\
-%     \verb|latex datetime2-german.ins|
-%     %
-%     \item
-%     Move all \texttt{*.ldf} files to \texttt{TEXMF/tex/latex/datetime2-contrib/datetime2-german/}
-% \end{enumerate}
-% Then, you can compile the documentation yourself by executing \\[\smallskipamount]
-%\verb|pdflatex datetime2-german.dtx| \\
-%\verb|makeindex -s gind.ist datetime2-german.idx| \\
-%\verb|makeindex -s gglo.ist -o datetime2-german.gls datetime2-german.glo| \\
-%\verb|pdflatex datetime2-german.dtx| \\
-%\verb|pdflatex datetime2-german.dtx| \\[\medskipamount]
-% or just use the precompiled documentation shipped with the sorce files. \\
-% In both cases, copy the files \texttt{datetime2-german.pdf} and \texttt{README.md} to \\
-% \texttt{TEXMF/doc/latex/datetime2-contrib/datetime2-german/}

-% \subsection{Loading a language module}
-% \textit{There are three different ways to load the required language module. See the \sty{datetime2} documentation for further details}
+% This file contains the style used when German is requested without a known region.
 %
 % \medskip
-%
-% \textbf{Variant 1:} \\
-% Request the desired language module explicitly by passing the "german", "de-DE", "de-AT" or "de-CH" option to the \sty{datetime2} package: \\[\smallskipamount]
-%\verb|\documentclass{article}| \\
-%\verb|\usepackage[german]{datetime2}| \\
-%\verb|\begin{document}| \\
-%\verb|\today| \\
-%\verb|\end{document}| \\[\medskipamount]
-%
-% \textbf{Variant 2:} \\
-% Load \sty{babel} and pass the "german", "austrian" or "swissgerman" option to the \verb|\documentclass| command (or to \sty{babel} directly). If you now pass the \opt{useregional} option to \sty{datetime2}, the language module suitable to the one specified with \sty{babel} is loaded: \\[\smallskipamount]
-%\verb|\documentclass[german]{article}| \\
-%\verb|\usepackage{babel}| \\
-%\verb|\usepackage[useregional]{datetime2}| \\
-%\verb|\begin{document}| \\
-%\verb|\today| \\
-%\verb|\end{document}| \\[\medskipamount]
-%
-% \textbf{Variant 3:} \\
-% When using \sty{polyglossia}, you should request the desired language module by passing the "german", "de-DE", "de-AT" or "de-CH" option to the \sty{datetime2} package: \\[\smallskipamount]
-%\verb|\documentclass{article}| \\
-%\verb|\usepackage{polyglossia}| \\
-%\verb|\setmainlanguage{german}| \\
-%\verb|\usepackage[german]{datetime2}| \\
-%\verb|\begin{document}| \\
-%\verb|\today| \\
-%\verb|\end{document}|
-%
-%
-% \subsection{Other features}
-% \subsubsection{Showing the weekday}
-% All language modules shipped with \sty{datetime2-german} support showing the weekday. \\
-% To enable this feature, pass the \opt{showdow} option to the \sty{datetime2} package. \\
-% Please note, that this has no effect when using the "numeric" style of the "de-AT" variant.
-%
-% \subsubsection{Using abbreviated weekday and month names}
-% To enable abbreviated weekday and month names, use \verb|\DTMlangsetup[german]{abbr}|. \\
-% To disable them, use \verb|\DTMlangsetup[german]{abbr=false}|.
-%
-% \medskip
-% In both cases, replace "german" with the used variant style ("de-DE", "de-AT" or "de-CH"). \\
-% Please note, that this has no effect when using the "numeric" style of the "de-AT" variant.

-% \section{Further customization of styles}
-% There are a number of settings provided that can be used in \verb|\DTMlangsetup| to modify the date-time style. These are:
-% \begin{description}
-%	\item["dowdaysep"]%
-%	The separator between the day of week name and the day of month number.
-%
-%	\item["daymonthsep"]%
-%	The separator between the day and the month name
-%
-%	\item["monthyearsep"]%
-%	The separator between the month name and year
-%
-%	\item["datesep"]%
-%	The separator between the date numbers in the "numeric style"s
-%
-%	\item["timesep"]%
-%	The separator between hours, minutes and seconds
-%
-%	\item["datetimesep"]%
-%	The separator between the date and time for the full date-time format
-%
-%	\item["timezonesep"]%
-%	The separator between the time and zone for the full date-time format
-%
-%	\item["abbr"]%
-%	This is a boolean key. If "true", the month (and weekday name, if shown) is abbreviated.
-%
-%	\item["mapzone"]%
-%	This is a boolean key. If "true", the time zone mappings are applied.
-%
-%	\item["showdayofmonth"]%
-%	A boolean key that determines whether or not to show the day of the month
-%
-%	\item["showyear"]%
-%	A boolean key that determines whether or not to show the year
-%\end{description}
-%
-%
-% Although the keys listed here are \textit{defined} for all variant styles, it depends on \sty{datetime2}'s setup and the requested styles whether they're \textit{used}. \\
-% For more information about the \verb|\DTMlangsetup| command see the documentation of the main \sty{datetime2} package.
