%% eurosis.sty
%% A simple style package conforming (more or less) to EUROSIS guidelines 
%% for paper submission. The packsge should be used as shown in the
%% example.tex file that comes with this style.
%% Generaly, the style should be used in combination with article class
%% with a4paper and two column layout:
%%
%% \documentclass[a4paper,twocolumn]{article}
%% \usepackage{eurosis}
%%
%% It is the user's responsibility to capitalise section headings and
%% paper's title according to the EUROSIS guidelines:
%%
%% \title{TITLE IN ALLCAPS}
%%
%% \section{SECTION HEADINGS}
%% \subsection{Second level headings}
%% \subsubsection{Third level headings}
%%
%% This style has been put together by:

\setlength{\columnsep}{1cm}
\setlength{\textwidth}{18cm}
\setlength{\textheight}{24cm}
\setlength{\topmargin}{-1.5cm}
\setlength{\oddsidemargin}{-1cm}
\setlength{\evensidemargin}{-1cm}
\pagestyle{empty}

%% New simplified section, subsection, abstract and keywords
%% commands. I hope you don't refer to sections in paper, as they
%% don't use counters, so \label \ref would not work properly (but
%% sections are not numbered anyway, so that makes no sense).
