% umcite.tex based on rlcite and rlxcite
% Adds to LaTeX four macros to make it possible to cite as follows:
% \citec renders `Van den Bosch {\em et~al}. (1989)'
% \cited renders `(Van den Bosch {\em et~al}., 1989)'
% \citee renders `Van den Bosch {\em et~al}., 1989'
% \citef renders `(1989)'
% \citeg renders `1989'
