% chi2001.sty
%
% Suspiciously similar to uist99.sty.
% Note that you need to manually make sure that the columns on the last
% page are the same length (described at the end of these comments).
%
% Originally developed by Stephane Chatty [chatty@dgac.fr].
% Modifications by Steve Feiner [feiner@cs.columbia.edu] noted with SKF.
% Modified by Dennis Chao for CHI 2001
%
% The style for UIST'99 submissions is that same as we've used in the
% past few years.
%
% chi2001.sty is to be used like this:
%
% \documentstyle[times,chi2002]{article}
% \begin{document}
% \title{Your Title}
% \author{Your name and address}
% \maketitle
% \abstract
% Your abstract goes here.
% \keywords Your, keywords, go, here, separated, by, commas
% \section{INTRODUCTION}
% Etc., etc. . . .
% \end{document}
%
% I was not able to redefine the output routine in order to
% make the two columns of the last page equal in length.
% To do that, add a \linebreak (to justify the current line)
% and \newpage (to start a new column)
% at the right place in the text on your last page.
