%
% \section{Introduction}
% %%%%%%%%%%%%%%%%%%%%%%%
%
% The purpose of this class is to make the proceedings of the ACM
% to look more similar.
% The 'acmconf' class is an extension (or restriction as one sees) of the
% standard 'article' class.
% The text is typeset within two columns, the page bounds (width and height)
% are predefined and should not be modified.
% You may use all stuff of the 'article' class in the 'acmconf' class.
% (E.g.~'\title', '\author', '\maketitle', '\section', '\tabular', etc.
% Please have a look to the examples shipped with this class).
%
% The layout produced by the 'acmconf' class is based on the description
% contained in \texttt{www.acm.org/sigs/pubs/proceed/pubform.doc}\footnote{It
% follows this document concerning fonts and sizes, etc., but some
% distances (e.g.\ before and after section heads), are taken unchanged form
% the 'article' class, which results in differences to the file
% \texttt{pubform.doc}.}. For the specification of the layout, have a look into
% the file \texttt{pubform.tex} (with is the \LaTeX2e-variant of
% \texttt{pubform.doc}).
%
% The page \texttt{www.acm.org/sigs/pubs/proceed/template.html} contains
% the \emph{ACM SIG Proceedings Templates} for some other word processors.
%
% Besides the layout, this class offers some support in managing the
% process of preparing, submitting, and publishing the paper.
% The basic idea is that a paper is in one of the following five "states":
% \begin{enumerate}
% \item First the paper is in \emph{preparation}, then it will be
% \item \emph{submitted} to the conference chair.
% \item It may be \emph{accepted}, but is not yet published in the proceedings,
% \item then it must be typeset for the \emph{publication} in the proceedings,
%       and sometimes you need a
% \item \emph{printout} of the published paper.
% \end{enumerate}
%
% These states are indicated by the options passed to the class.
% Changing the option from one state to the next should not modify the
% printed result except for foot- and head lines (i.e.~each page should
% contain the same material on the same position on the page).
% The options are 'prepare', 'submit', 'accept', 'publish' and 'print'.
% In the text we speak of the \emph{prepared}, \emph{submitted},
% \emph{accepted}, \emph{published} or \emph{printed} text, as an
% abbreviation, that text was processed by \LaTeX\ with the corresponding
% option.
%
% Depending on the state, the head- and foot line of a page are filled
% with various informations (see below). Except for 'publish'  the foot line
% contains the page number, starting with one.
%
% Depending on the state, some macros must be used to define important
% informations (e.g.~the conference name must be given always, while
% the copyright notice must be given only when the 'publish' or 'print'
% option is used. Warnings will be emitted, if they are missing.
%
% You may give conditional text depending on the option, using the
% '\If...' commands shown below. Using them may cause different results when
% printing the text.
%
% \section{Thanks}
% %%%%%%%%%%%%%%%%
%
% The initial layout of this class was based on the former \LaTeX-style file,
% which states:\\
%    \emph{Adapted from ARTICLE document style by Ken Traub.
%          Hacked for [preprint] option by Olin Shivers 4/91.
%          Fixed up for LaTeX version 2e by Peter Lee 10/94 (with
%          help from Simon Peyton Jones).}
%
% The 'flushend'-package of  Sigitas Tolu\v sis \texttt{sigitas@vtex.lt} is
% used to balance the columns on the last page of the paper. It is
% \emph{Copyright 1997 Sigitas Tolu\v sis, VTeX Ltd., Akademijos 4,
% Vilnius, Lithuania}. Its ``home'' is
% \texttt{www.vtex.lt/tex/download/macros/flushend.sty}.
%
% The 'flushend'-package is distributed with the permisssion of
% Sigitas Tolu\v sis together with the 'acmconf' class. It is stored
% in the separate file \texttt{flushend.sty}.
%

% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% The 'flushend' package of Sigitas Tolu\v sis \texttt{sigitas@vtex.lt} is
% used to balance the columns on the last page of the paper.
% It is loaded automatically by the 'acmconf' class.
% It offers the following commands:
% \begin{itemize}\setlength{\itemsep}{0cm}
% \item \DescribeMacro{\flushend}
%        '\flushend'\\
%        Switches on column balancing at last. This is the default.
% \item \DescribeMacro{\raggedend}
%        '\raggedend'\\
%        Switches off column balancing at last page.
% \item \DescribeMacro{\atColsBreak}
%       '\atColsBreak'\Meta{text}\\
%        Adds \meta{text} in place of original column break
%        (without balancing). Example: '\atColsBreak{\vskip-2pt}'.
%\item \DescribeMacro{\showcolsendrule}
%      '\showcolsendrule'\\
%      Adds rule to the bottom of columns (just for debugging).
% \end{itemize}

% \subsection{Predefined Stuff}
% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% 'acmconf' defines the following things, which should not be overwritten
% by the user:
% \begin{itemize}\setlength{\itemsep}{0cm}
% \item The paper is set in twocolumn-mode. The columns on  the last page
%       are balanced.
% \item The '\normalfont' size is 9pt with a '\baselineskip' of 9pt and a
%       '\baselinestretch' of 1.2.
% \item The page size and some distances.
% \item The layout of '\section', '\subsection', '\subsubsection',
%       '\paragraph', and '\subparagraph'.
% \end{itemize}

\begin{abstract}
  This document demonstrates how to use the \LaTeX2e \verb|acmconf|
  class by exhibiting itself as an example.  You are expected to be
  familiar with~\cite{Lam94}.  The best way to use this file is to use
  it as a template, i.e., replace the prose in it by your
  own\footnote{And may use footnotes.}.
\end{abstract}

\begin{keywords}
\LaTeX2e-class, ACM proceedings
\end{keywords}

\section{Introduction}
To understand this file read the \emph{source} and not the typeset
version.  If you are reading this in the typeset version you might as
well stop --- it is not supposed to make sense.

\section{The Story Begins\ldots}
A real article is supposed to have some deep results and good
explanations.  That, however, is your job and not mine so you should
replace this text with something more appropriate\footnote{Another a
  footnote}..

\section{Some often used \LaTeX\ commands}

\section{Introduction}

The proceedings are the records of the conference. ACM hopes to
give these conference by-products a single, high-quality appearance.
To do this, we ask that authors follow some simple guidelines. In
essence, we ask you to make your paper look exactly like this
document. The easiest way to do this is simply to down-load a
template from \cite{template.1999}, and replace the content with
your own material.

\section{Page Size}

All material on each page should fit within a rectangle of
18 x 23.5 cm (6" x 9.25"), centered on the page, beginning
2.54 cm (1") from the top of the page and ending with
2.54 cm (1") from the bottom.  The right and left margins
should be 1.9 cm (.75'').  The text should be in two
8.45 cm (3.33") columns with a .83 cm (.33") gutter.

\section{Typeset Text}

Prepare your submissions on a typesetter or word processor.

\subsection{Normal or Body Text}

Please use a 9-point Times Roman font, or other Roman font with
serifs, as close as possible in appearance to Times Roman in
which these guidelines have been set. The goal is to have a
9-point text, as you see here. Please use sans-serif or
non-proportional fonts only for special purposes, such as
distinguishing source code text. The Press 9-point font available
to users of Script is a good substitute for Times Roman. If
Times Roman is not available, try the font named Computer
Modern Roman. On a Macintosh, use the font named Times.
Right margins should be justified, not ragged.

\subsection{Title and Authors}

The title (Helvetica 18-point bold), authors' names (Helvetica
12-point) and affiliations (Helvetica 10-point) run across the full
width of the page - one column wide. We also recommend phone number
(Helvetica 10-point) and e-mail address (Helvetica 12-point). See the
top of this page for three addresses. If only one address is needed,
center all address text. For two addresses, use two centered tabs, and
so on. For more than three authors, you may have to
improvise\footnote{If necessary, you may place some address
information in a foortone, or in a named section at the end of your
paper.}

\subsection{First Page Copyright Notice}

Leave 3.81 cm (1.5") of blank space at the bottom of the left
column of the first page for the copyright notice.

\subsection{Subsequent Pages}

For pages other than the first page, start at the top of the page, and
continue in double-column format.  The two columns on the last page
should be of equal length.

\subsection{References and Citations}

Footnotes should be Times New Roman 9-point.

Use the standard Communications of the ACM format for references -
that is, a numbered list at the end of the article, ordered
alphabetically by first author, and referenced by numbers in
brackets \cite{anderson.1992}. See the examples of citations at
the end of this document
\cite{conger.1995,mackay.1995,schwartz.1995}. Within this template
file, use the style named references for the text of your citation.

References should be published materials accessible to the public.
Internal technical reports may be cited only if they are easily
accessible (i.e. you can give the address to obtain the report within
your citation) and may be obtained by any reader. Proprietary
information may not be cited. Private communications should be
acknowledged, not referenced  (e.g., ``[Robertson, personal
communication]'').

\subsection{Page Numbering, Headers and Footers}

Do not include headers, footers or page numbers in your submission.
These will be added when the publications are assembled.

\section{Sections}

The heading of a section should be in Times New Roman 12-point bold in
all-capitals flush left.  Sections and subsequent subsections should
be numbered and flush left.

\subsection{Subsections}

The heading of subsections should be in Times New Roman 12-point bold
with only the initial letters capitalized. (Note: For subsections and
subsubsections, a word like the or a is not capitalized unless it is
the first word of the header.)

\subsubsection{Subsubsections}

The heading for subsubsections should be in Times New Roman 11-point
italic with initial letters capitalized.

\subsubsubsection{Subsubsubsection}

The heading for subsubsubsections should be in
Times New Roman 11-point italic with initial letters capitalized.

\subsubsubsubsection{Subsubsubsubsection}

The heading for subsubsubsubsections should be in
Times New Roman 11-point italic with initial letters capitalized.

\section{Figures/Captions}

Place Tables/Figures/Images in text as close to the reference as
possible.  It may extend across both columns to a maximum width of
17.78 cm (7'').

Captions should be Times New Roman 9-point bold.  They should be
numbered (e.g., ``Table 1'' or ``Figure 2'') and be centered beneath
each table, figure or image.

%% PURPOSE:   Balanced columns on last page in twocolumn mode.
%%
%% SHORT DESCRIPTION:
%%
%% \flushend (loaded by default)
%% ---------
%%   Switches on column balancing at last page
%%
%% \raggedend
%% ----------
%%   Switches off column balancing at last page
%%
%% \atColsBreak={#1}
%% ------------------
%%   Adds #1 in place of original column break (without balancing)
%%   Example: \atColsBreak{\vskip-2pt}
%%
%% \showcolsendrule
%% ----------------
%%   Adds rule to the bottom of columns (just for debugging)
%%
%% P.S. To stretch right column by #1 add command \vskip-#1 just before
%%      command \end{document}.
%%      TO shrink right column by #1 add command \vskip#1 just before
%%      command \end{document}.
%%      Example: \vskip-10pt
