%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 
% This LaTeX class is an extension to the slides class which 
% allows much nicer headers and footers which are customized
% to the International Computer Science Institute.
% 
% This is an adaptation from a LaTeX class from the
% University of Rhode Island.
% See following URL for examples:
% http://www.ele.uri.edu/Info/latex/slides/
% 
%
% All options from the class slides are allowed as well as:
%   bw: make the header bar, footer bar, and logo black and
%     white, instead of blue and gold.
%
%   portrait: landscape is the default orientation, this chooses
%     specifies portrait.
%
%   nofoot: no footer will be at the bottom, and the default
%     text of the slide will be one inch longer.  The page
%     numbers will be in the upper right.
%
% The additional functions available in this class are:
%   \slidetitle{title}: this sets the title of the current slide,
%     and must occur somewhere before the \end{slide}.
%
%   \tinycaption{caption}: this prints the caption in the lower
%     lefthand side of the slide.  It will affect all following
%     slides.
%
% Functions to change the header and footer (these all must
% appear before the \begin{document}):
%   \sitename{Site Name}: this sets the text in the lowerbar.
%     To have no name use \sitename{}.
%   
%   \sitenamecolor{color}: this specifies the color to use for
%     the site name in the lower bar.
%
%   \barcolor{color}: this is the bar color.
%
%   \newlogo{logo}[width]: this specifies the logo to use in 
%     the upper lefthand corner of the slide.  If the optional
%     width is not specified, it will default to 0.75in.  To have
%     no logo, use \newlogo{}.
