%% Changes by G. Alverson, Northeastern University, CMS Computing
% Addition of \checkoddpage as per bug list on sarovar.org
% Freeze original sarovar.org CVS info
%
% Note that \usepackage[draft]{pdfdraftcopy} with functioning left/right
% pages produced _two_ copies of the draft text string on each page, so I've
% commented out the ExecuteOptions{draft}
%
% Use of the outline format of the draft string (as in draftcopy using PS) is
% not available. Use instead the watermark option with your own pdf file.
