% Substyle to allow an ``alternative'' citation style that looks like
% author (date) and can be intermixed with the normal citation style.

%%% NOTE: This is a crock, adapted from LaTeX 2.09 code.
%%% If this stuff changes in later versions of LaTeX, this'll probably break.
%%% Also, the date must NOT start with a closed paren.  =)
