eqname: Names for Equations
With the little package eqname it is possible to label
equations with arbitrary strings in addition to the automatic
numbers provided by LaTeX. Referencing these strings is also
possible.
This result can be achieved with the following input:
\begin{eqnarray}
1+1=2 \label{e1}\\
1+2=3 \eqname{bingo}\label{e2}\\
1+3=4 \label{e3}
\end{eqnarray}
