+Here is a simple labelled equation:
+\begin{equ}[onelab]
+ \sum_{i=1}^5 X_i^j X^j_i = y^j \;.
+\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 \;.
+\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{equs}
+ f(x) &= \sin(x) + 1\;, \label{e:equ1}\\
+ h(x) &= f(x) + g(x) -3\;, \label{e:equ3}
+\end{equs}
+or with one number for the whole list
+\begin{equs}[e:block]
+ f(x) &= \sin(x) + 1\;, \\
+ h(x) &= f(x) + g(x) -3\;,
+\end{equs}
+using only a very small modification in the syntax. Of course, it can also have no number at all:
+\begin{equs}
+ f(x) &= \sin(x) + 1\;, \\
+ h(x) &= f(x) + g(x) -3\;.
+\end{equs}
+Let us make a first group:
+\minilab{otherlabel}
+\begin{equs}
+ f(x) &= \sin(x) + 1\;, \label{e:f}\\
+ g(x) &= \cos(x) - x^2 + 4\;,\label{e:g}\\[3mm]
+ h(x) &= f(x) + g(x) -3\;. \label{e:h}
+\end{equs}
+One can refer to the whole block \eref{otherlabel} or to one
+line, like \eref{e:f} for example.
+It is possible to use any tag one likes with the \texttt{\string\tag}
+command
+\begin{equ}[mylabel]
+ x = y\;. \tag{$\star$}
+\end{equ}
+Such an equation can be referred to as usual: \eref{mylabel}.
+Of course, \texttt{mhequ} can be used in conjunction with the usual \texttt{equation} environment,
+but \texttt{mhequ} is great, so why would you want to do this?
+\begin{equation}
+ x=y+z
+\end{equation}
+Typesetting several columns of equations is quite easy and doesn't require 10 different environments
+with awkward names:
+\begin{equs}
+ x&=y+z &\qquad a&= b+c &\qquad x&= v \label{laba}\\
+ x&=y+z &\qquad a&= b+c &\qquad x&= u+1\tag{\ref{laba}'}\label{labtag}\\
+ \multicol{4}{\text{(multicol)}} &\qquad x&=y \\
+ a&= b &\multicol{4}{\qquad\text{(multicol)}} \\
+ x&=y+z &\qquad a^2&= (b-c)^3 +y \\
+\intertext{and also (this is some \texttt{\string\intertext})}
+ x&=y+z &\qquad a&= (b+c)^2 - 5 &\qquad \ell&= m\label{labb}
+\end{equs}
+We can even extend the block \eref{otherlabel} much later like
+\minilab{otherlabel}
+\begin{equs}
+ x&=y+z &\quad x&=y+z &\quad f(x)&= b\label{e:x1}\\
+ x&=y+z & x&=y+z &\quad g(x)&= b\label{e:x2} \\
+ \multicol{6}{\sin^2 x + \cos^2 x = 1} \label{e:x3}
+\end{equs}
+It is possible to change the type of subnumbering and to use the
+\texttt{\string\text} command without having to load \texttt{amstext}, like so
+\setlabtype{Alph}
+\minilab{alab}
+\begin{equs}
+ I_1 &= \int_a^b g(x)\,dx\;,&\quad&\text{(First equation)} \label{e:1}\\
+ I_2 &= \int_a^b g(x^2-1)\,dx\;.&\quad&\text{(Second equation)} \label{e:2}
+\end{equs}
