% Note:  To avoid compatibility issues between geometry and at least one
% class file, it may be better to set all the dimensions by hand.

%  20 Nov 2014  - use `pageBreakSection` instead of clobbering `section`
%               - increase longest page size to 575cm
%               - make top, right, and left margins something sensible and
%                 a bit more aesthetically pleasing
%  24 Jan 2012  Argument to \SetScreen is screen width
%  23 Jan 2012  Remove package showlayout
%  22 Jan 2012  Initial version, based on ideas in 
%               B. Veytsman amd M. Ware, Tugboat 32 (2011) 261.
