+% which produces a double-spaced single column manuscript. The

-% The \opt{maxauthors} and \opt{usetitle} options change the output
-% of the \BibTeX\ style files.  \opt{maxauthors} is the number of
-% authors allowed before truncation to ``et~al.'' occurs.  The
-% default is 15, but can be increased (for example for supplementary
-% information).  Using the value $0$ means that all authors will be
-% added to the list.  The \opt{usetitle} option is a Boolean, and
-% sets whether the title of a paper referenced appears in the
-% bibliography.  The default is \opt{usetitle=false}.
+% Many journals require that long lists of authors are shortened using
+% `et al.' in the references section. The behaviour of the \BibTeX\ 
+% styles in this regard is controlled by two options, \opt{etalmode}
+% and \opt{maxauthors}. There are two possible ways to shorten a long
+% list of authors. Some journals require that only the first author
+% is given, followed by `et al.': for this behaviour, set
+% \opt{etalmode=firstonly}:
+%\begin{verbatim}
+%  Jones, A.N. et al.
+%\end{verbatim}
+% On the other hand, some journals request that the list of authors 
+% is truncated after $n$ authors. This is set up by the 
+% \opt{etalmode=truncate} option:
+%\begin{verbatim}
+%  Jones, A.N.; Bloggs, F.; Nobacon, D. et al.
+%\end{verbatim}
+% In both cases, the maximum number of authors permitted before 
+% introducing `et al.' is governed by the \opt{maxauthors} option.
+% This option recognises the sentinal value $0$, which indicates that
+% no shortening should occur at all.
