% The \copyrightspace command is used to produce a blank space in the first
% column where a copyright notice belongs.  It works by producing a
% blank footnote of the appropriate size.  Note that it should appear
% after any \footnote commands that produce footnotes for the first
% column, so it is invoked in maketitle.
