%\title{The `elmath' package}
%\author{Yannis Potamianos and Apostolos Syropoulos}
% \date{2004/11/20}
%\maketitle
% \begin{abstract}
% This package has been designed to partially implement the elmath-new input
% encoding in both and text and math modes. As such it supersedes package
% \textsf{elmath}, which was designed by the same authors. Note that if package
% \textsf{elmath-new} is used, then one should not use the (unofficial)
% \texttt{elmath-new} option of the \textsf{inputenc} package.
%\end{abstract}
%
% \section{Introduction and Usage}
% The package has been designed so to allow users with a Greek keyboard to
% type both Greek text and Greek mathematical symbols without any need to
% use special commands.
%
% Users of the package need only a standard ISO8859-7 keyboard, but obviously
% it is not difficult to adapt the package for other encoding.
%
% \section{The Implementation}
%
% Initially, we need to make sure that all the Greek letters are actually
% active. We assume that |~| is actually an active character.

% Now, we need to invoke the command |\el@math| every time we enter a math mode. For
% this reason we redefine the tokens |\everymath| and |\everydisplay| as follows:
% \begin{macrocode}
