% alleqno.sty -- LaTeX style file to make displayed equations numbered
% by default.
%
% This document style option makes all displayed equations numbered by
% default. In particular, it defines things so that \[, \], \[[, and
% \]] may be used as follows:
%
% \[ ... \] ==> \begin{equation} ... \end{equation}
% \[[ ... \]] ==> \begin{eqnarray} ... \end{eqnarray}
%
% These new commands are short, and they stand out clearly from the
% surrounding text on a terminal screen.
%
% Note that \begin{displaymath} ... \end{displaymath} should *not* be
% used with this style file -- use \[ ... \] instead. To override the
% default and get an unnumbered displayed equation, use a one-line
% \begin{eqnarray} ... \end{eqnarray}.
