\begin{document}
\maketitle

\begin{abstract}
This meta-paper describes the style to be used in articles and short
papers for SBC conferences. For papers in English, you should add just
an abstract and for the papers in Portuguese, we also ask for an
abstract in Portuguese (``resumo''). In both cases, abstracts should not
have more than 10~lines and must be in the first page of the paper.
\end{abstract}

\begin{resumo}
\begin{otherlanguage}{brazilian}
Este meta-artigo descreve o estilo a ser usado na confecção de artigos
e resumos de artigos para publicação nos anais das conferências
organizadas pela SBC. É solicitada a escrita de resumo e abstract apenas
para os artigos escritos em português. Artigos em inglês, deverão
possuir apenas abstract. Nos dois casos, o autor deve tomar cuidado para
que o resumo (e o abstract) não ultrapassem 10~linhas cada, sendo que
ambos devem estar na primeira página do artigo.
\end{otherlanguage}
\end{resumo}

\section{General Information}
All submitted paper to some SBC conference, including any supporting
documents, should be written in English or in Portuguese. The format
paper should be A4 with single column, 3.5~cm for upper margin, 2.5~cm
for bottom margin and 3.0~cm for lateral margins, without headers or
footers. The main font must be Times, 12~point nominal size, with
6~points of space before each paragraph. Page numbers must be
suppressed in the final version.

Full papers must respect the page limits defined by the conference.
Conferences that publish just abstracts ask for \textbf{one}-page
texts.

\section{First Page}
The first page must display the paper title, the name and address of
the authors, the abstract in English and ``resumo'' in Portuguese (for
papers written in Portuguese). The title must be justified at the
left, in 20~point boldface font. Author names must be justified in the
same way, as shown in this example.

\section{CD-ROMs and Printed Proceedings}
In some conferences, the papers are published on CD-ROM while only the
abstract is published in the Proceedings. In this case, authors are
invited to prepare two final versions of the paper. One, complete, to
be published on the CD and the other, containing only the first page,
with abstract and ``resumo'' (for papers in Portuguese).

\section{Sections and Paragraphs}
Section titles must be in boldface, 13pt, flush left. There should be
an extra 12~pt of space before each title. The first paragraph of each
section should not be indented; the first lines of subsequent
paragraphs should be indented by 1.27~cm.

\subsection{Subsections}
The subsection titles must be in boldface, 12pt, flush left.

\section{Figures and Captions}
\label{sec:captionmargins}
Figures and tables captions should be centered if less than one line
(Figure~\ref{figone}), otherwise justified and indented by 0.8cm on
both margins, as shown in Figure~\ref{figtwo}. The font must be
Helvetica, 10~point, boldface, with 6~points of space before and after
each caption.

\begin{figure}[h!]
	\centerline{\includegraphics{fig1}}
	\caption{A typical figure}
	\label{figone}
\end{figure}

In tables, do not use colored or shaded backgrounds, and avoid thick,
doubled, or unnecessary framing lines. When reporting empirical data,
do not use more decimal digits than warranted by their precision and
reproducibility. Table caption must be placed before the table (see
Table~\ref{tabone}) and the font used must also be Helvetica,
10~point, boldface, with 6~points of space before and after each
caption.

Figure and table references must be composed by the chapter number and
a sequence number beginning in one (see the examples of
Figure~\ref{figone}, Figure~\ref{figtwo} and Table~\ref{tabone}).

\begin{figure}[h!]
	\centerline{\includegraphics{fig2}}
	\caption{This figure is an example of a figure caption taking
		more than one line and justified considering margins
		mentioned in Section~\ref{sec:captionmargins}}
	\label{figtwo}
\end{figure}

\section{Images}
All images and illustrations should be in black-and-white, or gray
tones. The image resolution on paper should be about 600~dpi for
black-and-white images, and 150-200~dpi for grayscale images.  Do not
include images with excessive resolution, as they may take hours to
print, without any visible difference in the result.

\section{References}
Bibliographic references must be unambiguous and uniform.  We
recommend giving the author names references in brackets,
e.g.~[Knuth~1984], [Kernighan and Ritchie~1990]; or dates in
parentheses, e.g.~Knuth (1984), Sederberg and Zundel (1989,1990).
