+%\author{Nicola L. C. Talbot (inactive)}

+%\maketitle
+%
+%This module is currently unmaintained and may be subject to change.
+%If you want to volunteer to take over maintanance, contact me at
+%\url{http://www.dickimaw-books.com/contact.html}
+%
+%\begin{abstract}
+%This is the Latin 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}
+%
+%I've copied the date style from \texttt{babel-latin}'s \cs{today}.
+%This is different from \sty{polyglossia}'s Latin \cs{today} so
+%there's a check to see if \sty{polyglossia} has been loaded to make
+%the styles match.
+%
+%I don't know if these settings are correct.
+%In particular, I don't know if the "latin" time style is
+%correct. Currently this just uses the "default" time style. Please
+%be aware that this may change. Whoever takes over maintanance
+%of this module may can change it as appropriate.
+%
+%The new maintainer should add the line:
+%\begin{verbatim}
+% The Current Maintainer of this work is Name.
+%\end{verbatim}
+%to the preamble part in \texttt{datetime2-latin.ins} where Name
+%is the name of the maintainer(s) and replace
+%the `inactive' status to `maintained'.
+%
+%Currently there is only a regionless style.
