%This package provides support for Eqnarray environment, which is
%equivalent to the classical eqnarray version. The difference 
%between these two versions are that equation numbers in Eqnarray
%always start from 1, and are always in the plain style (even
%in case that equation numbers are defined to be dependend from
%the section, or subsection.)
%
%Sample usage:
%
% \begin{Eqnarray}
% 1 + 1 & = & 2 \label{myequation}
% \end{Eqnarray}
% The equation (\ref{myequation}) shows us
%
% produces
%
%         1 + 1 = 2 (1)
% The equation (1) shows us
%
