%\title{Hebrew Module for datetime2 Package}
%\author{Nicola L. C. Talbot (inactive)}
%\date{2015-03-30 (v1.0)}
%\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 Hebrew 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}
%
%The date style simply uses either \sty{babel}'s \cs{hebdate}
%or \sty{polyglossia}'s \cs{hebrewdate} so the date style isn't
%expandable.
%
%I don't know if these settings are correct as I can't speak Hebrew.
%In particular, I don't know if the "hebrew" 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-hebrew.ins} where Name
%is the name of the maintainer(s) and replace
%the `inactive' status to `maintained'.
