% \section{Introduction}
%
% The \emph{ejpecp} \LaTeXe\ class is designed for the typesetting of
% articles for the mathematical research periodicals Electronic Journal or
% Probability (EJP) and Electronic Communications in Probability (ECP).
%
% \section{Usage}
%
% This class works only with the pdflatex engine. See the sample file for its
% usage.
%
% \iffalse 
%
% \DescribeMacro{\amacro} %
% This macro does nothing.\index{doing nothing|usage} It is merely an example.
% If this were a real macro, you would put a paragraph here describing what
% the macro is supposed to do, what its mandatory and optional arguments are,
% and so forth.
%
% \DescribeEnv{anenv} %
% This environment does nothing. It is merely an example. If this were a real
% environment, you would put a paragraph here describing what the environment
% is supposed to do, what its mandatory and optional arguments are, and so
% forth. %
