%% This file contains a class definition, infposter, for the LaTeX2e
%% system which defines the layout of posters in the style of
%% University of Edinburgh.
%%
%% For information on this class, please refer to "texdoc infposter"
%%
%% The following LaTeX packages are required by this class:
%%    pstricks - to embed the background EU crests and border.
%%    graphics - to display all EPS figures
%%    multicol - to produce the 3 column text.
%%    sectsty  - to redefine the font and colour of the headers
%%    url      - to typeset urls properly
