% This file contains the LaTeX formatting parameters for a two-column 
% conference proceedings that is 8.5 inches wide by 11 inches high.  

% Marginally hacked by Terran Lane, May 2003, to add ``Appearing in''
% at bottom of the first page.  The mechanism uses the
% ``fancyheadings'' style file, so you might have to download that if
% this breaks in your LaTeX installation.

% TODO: Make the ``appearing in'' note conditional, set by an argument
% to the style file.  That way we can suppress it for draft versions
% of the paper.  -- TDRL
