+%	A solution for using the textual comma character as decimal separator in math mode. \\[\medskipamount]
+%	\textbf{\texttt{textualicomma} is based on the \href{https://www.ctan.org/pkg/icomma}{\texttt{icomma} package} and intended as a solution for situations where the text comma character discerns from the math comma character.} Escaping to text mode every time a comma is used in math mode may slow down the compilation process. \\
+%	Please check, whether \href{https://www.ctan.org/pkg/icomma}{\texttt{icomma}} already satisfies your needs.

+% \subsection*{Obtaining the package and documentation file}
+% \begin{small}
+% 	You can obtain the package files by running \LaTeX\ over the file "textualicomma.ins": \\
+% 	"    latex textualicomma.ins"
+%
+% 	\medskip
+% 	For compiling the documentation, run \textbf{\hologo{LuaLaTeX}}~(!) twice over "textualicomma.dtx": \\
+% 	"    lualatex textualicomma.dtx" \\
+% 	"    lualatex textualicomma.dtx" \\
+% 	Please verify that all dependencies are fulfilled \emph{before} compiling.

+% \part{The documentation}
+% \section{Introduction}
+% Using the comma as decimal separator in ordinary \LaTeX\ has always been proble\-matic, since the comma is treated as a punctuation character and \LaTeX\ adds some space after it. \\
+% The solution was defining an ‘intelligent’ comma ‘recognizing’ whether it is used as decimal separator or punctuation character.
+%
+% \medskip
+% The common solution to this problem is the \texttt{icomma} package by Walter Schmidt \cite{icomma}. \\
+% However, some fonts, e.~g. Source Serif Pro, don't provide any math support. Although there are fonts looking very similar to Source Serif and providing math support (like Utopia and its ‘clones’ Fourier and Erewhon), more or less obvious differences are visible (compare ‘$,$’ to~‘,’). The only solution solving this ‘problem’ is escaping to text mode.
+%
+% \section{The \texttt{textualicomma} package}
+% \subsection{\texttt{textualicomma}'s behaviour}
+% \texttt{textualicomma} makes some changes and additions to \texttt{icomma}'s code in order to provide automated escaping to text mode. The behaviour remains the same:
+% \begin{itemize}
+%     \item The comma is treated as decimal separator if it is directly followed by a number. Thus, a number is to be entered as, for instance, \\
+%           "3,142"
+%     \item whereas mathematical expressions like $(x\text{,}\,y)$ are to be written with a space after the comma: \\
+%           \verb*|(x, y)|
+% \end{itemize}
+%
+% Also, the period is redefined so that it adapts to the used font.
+%
+%
+% \subsection{Package options}
+% By default, the font used for typesetting the comma is the roman text font. This behaviour can be modified by using package options:
+% 
+% \medskip
+% \DescribeMacro{sffamily}
+% Passing the "sffamily" option to "textualicomma" results in the comma being printed using the loaded sans serif font
+%
+% \medskip
+% \DescribeMacro{ttfamily}
+% Passing the "ttfamily" option to "textualicomma" results in the comma being printed using the loaded typewriter font
+%
+% \bigskip
+% \DescribeMacro{\textualicommafont}
+% Both options change the used font \emph{for the whole document}. Changes inside a document can be made using the "\textualicommafont" command: \\
+% "\textualicommafont{\rmfamily}" \\
+% "\textualicommafont{\sffamily}" \\
+% "\textualicommafont{\ttfamily}" \\
+%
+%
+%
+% \section{Bugs and problems}
+% Generally, since the comma is made ‘active’, problems are not unlikely.
+%
+% \medskip
+% For example, when using the ‘intelligent comma’ together with the \texttt{dcolumn} package, a comma to be \textit{printed} as the decimal separator in a column of type "D" is to be specified as "{\mathord\mathcomma}", rather than "{,}", since the latter leads to an error. For instance:
+%
+% \begin{center}
+%     \verb|\begin{tabular}{... D{,}{\mathord\mathcomma}{2} ...}|
+% \end{center}
+%
+% Note that specifying the comma as the related input character works as usual.
