% Modified for european a4 paper size and font size requirements for LT2K++
%
% TEMPLATE for Usenix papers, specifically to meet requirements of
%  TCL97 committee.
% originally a template for producing IEEE-format articles using LaTeX.
%   written by Matthew Ward, CS Department, Worcester Polytechnic Institute.
% adapted by David Beazley for his excellent SWIG paper in Proceedings,
%   Tcl 96
% turned into a smartass generic template by De Clarke, with thanks to
%   both the above pioneers
% use at your own risk.  Complaints to /dev/null.
% make it two column with no page numbering, default is 10 point

% include following in document.
%\documentclass[a4paper,10pt]{article}
%\usepackage{twocolumn,times}
%\pagestyle{empty}

% force european A4 paper format
\setlength{\textwidth}{16.6cm}     % width of main text
\setlength{\textheight}{25cm}    % height of main text
\setlength{\topmargin}{-1in}     % Subtract default offset
\addtolength{\topmargin}{2.2cm}    % Topmargin 
\setlength{\topskip}{0pt}        % between header and text
\setlength{\headheight}{0.0in}   % no header
\setlength{\headsep}{0.0in}      %
\setlength{\oddsidemargin}{-1in}   % Subtract default offset
\addtolength{\oddsidemargin}{2.2cm}  % odd page left margin
\setlength{\evensidemargin}{-1in}  % Subtract default offset
\addtolength{\evensidemargin}{2.2cm} % odd page left margin

% set dimensions of columns, gap between columns, and space between paragraphs
\setlength{\columnsep}{0.25in}
\setlength{\parindent}{0pt}
\setlength{\parskip}{\baselineskip}

% started out with art10.sty and modified params to conform to IEEE format
% further mods to conform to Usenix standard
