\begin{document}
\maketitle
\begin{abstract}
  This document contains special instructions for preparing papers for
  inclusion in the proceedings of the ACL 2005 Workshop on Software.
\end{abstract}

\section{Obligatory}

Important: \emph{Follow the formatting guidelines for the Main Session,
  unless otherwise noted.}

However, the workshop proceedings differ in several important aspects.
First, there are no page limitations.  However, I would strongly
advise you to keep your papers under 20 pages total.  Please format
papers according to standard procedure: floating figures and tables
should occur close to where they are referenced (not in an appendix).
If you want to include source code for software that you've written,
please submit additional files -- don't include complete source code
in the paper's appendices.

A second difference is page size.  Papers should be formatted for a
page size of $595$ by $792$ PostScript points (``big points'' in \TeX\
terminology).  This is the size of the largest rectangle that will fit
in both US Letter paper and ISO A4 paper.  (This does not seem to work
if you work in a traditional DVI $\to$ PostScript $\to$ PDF chain; in
this case, please use US Letter paper).

Third, please use the \verb|mathptmx| package instead of the obsolete
\verb|times| package.  See the source code of this file for an
example.

Fourth, feel free to use color in figures.  To include figures, please
use \verb|\includegraphics| from the standard \LaTeX\ package
\verb|graphicx|.

You will need to submit high-quality PDF files.  This almost
invariable means using a recent version of pdf\LaTeX\ to prepare PDF
files.  I recommend the \href{http://tug.org/tetex/}{te\TeX\
  distribution} version 3.0 or higher.  Make sure that all fonts
(except for possibly the PDF ``Base 14'' fonts) are embedded as Type~1
or TrueType fonts in the PDF file.  You can check which fonts are
included using Acrobat or the \verb|pdffonts| utility that comes with
xpdf.

\section{Optional}

\begin{table}[t]
  \capstart
  \centering
  \begin{tabular}{cc}
    systolic (mm Hg) & income (kUSD) \\
    \hline
    120 & 80 \\
    200 & 160 \\
  \end{tabular}
  \caption{A floating table}
  \label{tab:example}
\end{table}

You may consider using the \verb|hyperref| package if you want to use
internal or external links (this is completely optional).  See the
source code of this file for an example.  It allows you to use links
to sections and tables, like this one: \TabRef{example}.

If you do use \verb|hyperref| you cannot use ACL's \verb|acl.bst|
Bib\TeX\ style.  Instead, use the \verb|natbib| package together with
the \verb|aclnat.bst| style file provided by me.  This allows you to create
automatically hyperlinked references like this: ``It has been claimed
\citep{kay1979syntactic}\dots'' or ``\citet{kay1979syntactic} claims\dots''
