+%\title{Irish Module for datetime2 Package}
+%\author{Nicola L. C. Talbot (inactive)}
+%\date{2018-04-24 (v1.1)}
+%\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 Irish 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-irish}'s \cs{today}.
+%
+%I don't know if these settings are correct as I can't speak Gaelic.
+%In particular, I don't know if the "irish" 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-irish.ins} where Name
+%is the name of the maintainer(s) and replace
+%the `inactive' status to `maintained'.
+%
+%Regional styles are named in the form \texttt{\meta{language
+%code}-\meta{country code}} (or \texttt{\meta{language
+%code}-\meta{country code}-numeric}) where \meta{language code} is
+%the ISO 639-1 language code (\texttt{ga} in the case of Irish
+%Gaelic) and \meta{country code} is the ISO 3166-1 country code
+%(\texttt{IE} for the Republic of Ireland and \texttt{GB} for the
+%United Kingdom of Great Britain and Northern Ireland). You will
+%need \sty{tracklang} v1.2 for the "ga-IE" and "ga-GB" options.
+%The only difference between them is the Summer time zone mappings
+%with IST (Irish Summer Time) for "ga-IE" and BST (British Summer
+%Time) for "ga-GB". The regionless "irish" style uses WET (Western
+%European Time) and WEST (Western European Summer Time).
