+% \section{Introduction}
+%
+% Problem: The |eqnarray| environment is too restrictive because it is
+% only prepared to accept three part equations. Some applications
+% require more sophisticated mathematics, so three parts aren't
+% enough. Simultaneously, we would like to have our equations
+% numbered. If the equations aren't to be numbered, then the |array|
+% environment suffices.\footnote{Nevertheless it is often easier to use the
+% |equationarray*| environment than both an |equation| plus an |array|
+% environment. Moreover a page break is possible between two lines of the
+% |equationarray|.} If the equations aren't to be aligned with
+% each other, then the |equation| environment is preferred.
+%
+% A first version of the |equationarray| environment was written by
+% Tony Li, University of Southern California, |<tli@sargas.usc.edu>|
+% starting 6/15/1988. The current version has been completely
+% rewritten in order to make it compatible with Frank Mittelbach's
+% |array| environment, i.e., it should be possible to use all features
+% of the |array| environment. If you find a bug (see below!) or if you
+% make any improvements, I'd like to hear about them.
+%
+% \section{Example}
+%
+% We give a short example for the use of |equationarray|. The text is
+% %
+% \begin{verbatim}
+% \newcolumntype{e}{@{\quad}}
+% \arraycolsep 0.2em
+% \begin{equationarray}{p{2.5em}erclecercl}
+% now: & - i\partial_t \psi & = & H\,\psi & \Rightarrow
+% & \psi (t) & = & \psi (0) \exp (iEt) \\[3ex]
+% then: & - i\partial_t \psi & = & (H+E_0) \,\psi & \Rightarrow
+% & \psi (t) & = & \psi (0) \exp [i(E+E_0)t]
+% \end{equationarray}
+% \end{verbatim}
+% %
+% \noindent and we obtain
+% %
+% \newcolumntype{e}{@{\quad}}
+% \arraycolsep 0.2em
+% \begin{equationarray}{p{2.5em}erclecercl}
+% now: & - i\partial_t \psi & = & H\,\psi & \Rightarrow
+% & \psi (t) & = & \psi (0) \exp (iEt) \\[3ex]
+% then: & - i\partial_t \psi & = & (H+E_0) \,\psi & \Rightarrow
+% & \psi (t) & = & \psi (0) \exp [i(E+E_0)t]
+% \end{equationarray}
+% %
+% An |equationarray| behaves very much like an |array|. For example,
+% |equationarray| accepts the same tokens for defining columns, and
+% new column types can be defined with |\newcolumntype|. One can use
+% |\multicolumn|, |\hline|, |\cline|, and |\vline|. Moreover,
+% |equationarray| makes use of |\arraycolsep|, |\extracolsep|, and
+% |\extrarowheight|.\footnote{Some people don't like the large spacing
+% between the columns of the standard |eqnarray|. Don't be surprised
+% that |equationarray| seems to have the same ``bug''. To decrease
+% the spacing between two columns you just have to change the value
+% of $\tt\backslash$|arraycolsep|, see the example above.} In an
+% |equationarray| all these things have the same meaning like in an
+% |array|. The main difference is that by default each entry of an
+% |equationarray| is displayed with |\displaystyle| whereas |array|
+% uses |\textstyle|. One can avoid page breaks between two lines by
+% using the star version |\\*|. There is also the star version
+% |equationarray*| which has usually no line numbers. But if for a
+% particular line you still want a line number, you can use
+% |\yesnumber|. (I find this more convenient than having many lines
+% with |\nonumber|.) Inside the |equationarray| and |equationarray*|
+% environments, there is also the macro |\eqnnum| available. It takes
+% one argument that is used as the equation number for the current
+% line. The normal line number is always suppressed in such a line.
+%
+% The default is that without the |fleqn| option the equations are
+% centered. With the |fleqn| option they are left-justified, indented
+% by |\mathindent|.\footnote{Thanks to Piet van Oostrum
+% |<piet@cs.ruu.nl>| who added the code which is necessary for the
+% |fleqn| option.} With the optional argument |[l]| or |[r]| the
+% |equationarray| will appear flushleft or flushright, with the option
+% |[c]| the |equationarray| will be centered, e.g.\
+% |\begin{equationarray}[l]{rclll}|.
+%
+% \section{Bugs}
+%
+% Compared with |array| the |equationarray| uses slightly extended
+% versions of |\@classz| and |\multicolumn| because it must count the
+% columns. Each time you insert a |&| the counter |\@eqcnt| is
+% increased by one. |\multicolumn| increases |\@eqcnt| according to
+% the number of |\span|ed columns. Thus if you have an |array| within
+% the |equationarray| environment and in that line of the
+% |equationarray| you have less |&|'s than columns defined in the
+% preamble, then the line numbering will be not flushright but further
+% to the left.
+%
+% In that case you can either fill up the end of the line with extra
+% |&|'s (straightforward) or you can put the original definition of
+% |\@classz| and |\multicolumn| within the definition of the |array|
+% command.
