% \titlerule % A nice centered \hrule
% \author{I. Newton, {\rm Department of Cyberethics}}

% }
% All items (except \title) are optional.
% Any of them can be used inside either
% \columntitlestuff{} or \pagetitlestuff{}. The first option will
% typeset those items left-justified on top of the first column.
% The second option will center them on top of the first page,
% spanning both columns.
% Note that \columntitlestuff and \pagetitlestuff must occur before
% any contribution to the first page of the paper.
