+This package provides two environments: \texttt{equ} for single-line equations
+and \texttt{equs} for multi-line equations. They behave similarly to the built-in
+\texttt{equation} and \texttt{amsmath}'s \texttt{align} environments and can essentially
+be used as drop-in replacements. The main difference is that equation numbers are
+handled differently: equations are numbered if and only if they have a \verb|\label|,
+so there is no need for starred versions. This also applies to individual lines in
+a multiline equation. Also, the \texttt{equs} environment supports blocks of equation
+with more
+
+Since \texttt{mhequ} redefines the \verb|\tag| and \verb|\intertext| commands, it should
+always be loaded \textit{after} the \texttt{amsmath} package. However, these
+two commands should still behave correctly inside the \texttt{amsmath} environments.
+The rest of this document demonstrates the usage of the \texttt{mhequ} package,
+it is easiest to just read the source code of this document to see how it works.
+See also the description given at the start of the file \texttt{mhequ.sty}.
+
Here is a simple labelled equation:
\begin{equ}[onelab]
- \sum_{i=1}^5 X_i^j X^j_i = y^j \;.
+ e^{i\pi} + 1 = 0 \;.
\end{equ}
Removing or adding the label does not require a change of environment:
\begin{equ}
- \sum_{i=1}^5 X_i^j X^j_i = y^j \;.
+ e^{i\pi} + 1 = 0 \;.
\end{equ}
However, if the option \texttt{numberall} is set, then every single
equation is numbered.
A simple list of equations can be displayed either with one number
per equation
+\begin{align}
+ f(x) &= \sin(x) + 1\;, \label{e:equ1}\\
+ h(x) &= f(x) + g(x) -3\;, \label{e:equ3}
