% documentclass AISB2010 based on AISB2008 class
%
% AISB is using the ECAI format
%

% This file is an adaption of ecai98.cls. It provides the same style
% as ecai98.cls but removes any footer.
% ecai98.cls was created by merging the ECAI-96 document style with the
% latex2e article class. It has inherited most of the features (and bugs)
% of the ECAI-96 document style, but only promises to approximate that style.

% For users without access to latex2e, a style file for latex209
% is also available. This works with latex209 (but not with latex2e).

% Both these style files are available via
%   http://www.ai.univie.ac.at/ecai/latex
