%   \begin{sli}{<Title of slide>}
% 
%     <text of the slide>
%

% This environment creates a page like this:
% 
%
%
%     					 
%              <Title in bold>		 
%     					 
%     					 
%     	Text in sans-serif style	 
%     	with usual LaTeX commands	 
%     	NB. some fontsize commands are	 
%     	redefined			 
%     					 
%     	.......				 
%     					 
%     					 
%     					 
%     					 
%     					 
%     					 
%      <note>			  <num>  
% 
% The note is printed in very small fontsize and is default set
% to "\today". It can be redefined with:
% 
% \renewcommand{\slinote}{Lecture XXX, ...}
% 
% Each slide is numbered. Note that the "psfig.sty" file must be one of
% the optional parameters of the documentstyle.
