%
% ----------------------------------------------------------------------
%
% This is the LaTeX style file for ACL-COLING 1998.  It is based on
% a series of similar files prepared for previous conferences by
% Fernando Pereira, Paul Jacobs, Stuart Shieber, Peter F. 
% Patel-Schneider and others.  Various changes have been made, chiefly
% to save space in the final output or remove redundant definitions. 
%
% colacl.sty is designed for use as a package or option with the
% standard LaTeX article class, and the BibTeX style acl.bst.
%
% Author/title and citation formatting differs slightly from standard
% LaTeX; see AUTHOR FORMATS and CITATION FORMATS below for more
% information.
% 
% This file is supplied as a hopefully convenient implementation of 
% some of the "instructions for authors" repeated below.  It is not
% guaranteed to work in any given LaTeX installation or in conjunction
% with any given class, package or style, and it is not intended as
% a LaTeX tutorial.
%
% ----------------------------------------------------------------------
% Instructions for authors
% 
%   (i) Maximum length of full papers: 7 pages.  An eighth page may be
%       used for one or more abstracts in languages which differ from
%       that used for the body of the paper.  For project notes, 5
%       pages, with an optional sixth for abstract(s).
%
%  (ii) Paper size: A4 or US Letter.
%
% (iii) Margins: set so that text lies within a rectangle 9in (23cm)
%       high and 6.5in (16.5cm) wide.
%
%  (iv) Body of text to be set in two columns.  Full-width figures
%       (i.e. using \begin{figure*}) and tables may be used if
%       necessary. 
%
%   (v) Use standard fonts, e.g. Computer Modern Roman, Times Roman, no
%       smaller than 10pt.
%
%  (vi) No page numbering (pages should be numbered in pencil, on the
%       reverse side).
% 
% Items (iii), (iv) and (vi) are handled by this file, and should
% therefore not be overridden by resetting \textwidth, \textheight,
% \pagestyle etc. in your document, or by using styles or packages
% which have the same effect.
%
% ----------------------------------------------------------------------
% To convert papers prepared with colaclsub.sty to the final format
% for use with colacl.sty:  
%
% (1) Remove commands specific to the original submission format 
%     (\type, \subject, \contact, \conference, \makeidpage).
% 
% (2) Replace \summary{...} with an abstract, using the normal
%     abstract environment, placed after \maketitle.
%
% A simple document template:
%
%   \documentclass[11pt]{article}
%   \usepackage{colacl}
%   \title{...}
%   \author{...}             % see below for possible formats
%   \begin{document}
%   \maketitle
%   \begin{abstract}
%   ...                      % contents of abstract
%   \end{abstract}
%   ...                      % contents of article
%   \bibliographystyle{acl}  % use acl.bst
%   \bibliography{...}
%   \end{document}
%
% Users of obsolete LaTeX versions can try:
%
%   \documentstyle[colacl]{article}	% or [11pt,colacl]
%   \title{...}
%   ...
%
%
% ----------------------------------------------------------------------
% AUTHOR FORMATS
%
% Author information can be set in various styles.
%
% For several authors from the same institution:
% \author{Author 1 \and ... \and Author n \\
%	  Address line \\ ... \\ Address line}
% if the names do not fit well on one line use
%         Author 1 \\ {\bf Author 2} \\ ... \\ {\bf Author n} \\
%
% For authors from different institutions:
% \author{Author 1 \\ Address line \\  ... \\ Address line
%	  \And  ... \And
%	  Author n \\ Address line \\ ... \\ Address line}
%
% To start a separate "row" of authors use \AND, as in
% \author{Author 1 \\ Address line \\  ... \\ Address line
%	  \AND
%	  Author 2 \\ Address line \\ ... \\ Address line \And
%	  Author 3 \\ Address line \\ ... \\ Address line}
%
% If the title and author information does not fit in the area allocated,
% place \setlength\titlebox{<new height>} after \usepackage{colacl},
% where <new height> can be something larger than 2.0in
%
% ----------------------------------------------------------------------
% CITATION FORMATS
% 
% Three possible citation formats:
% "\cite{...}"      produces a citation like "(Author, 1999)"
% "\shortcite{...}" produces a citation like "(1999)"
% "\newcite{...}"   produces a citation like "Author (1999)"
%
% All three take an optional argument which can be used to add page
% references, etc.:
% "\newcite[1--6]{...}" produces a citation like "Author (1999, 1--6)"
%
% ----------------------------------------------------------------------
% IF IT DOESN'T WORK
%
% The error message "File `colacl.sty' not found." indicates that this
% file has not been installed in a location which is visible to your 
% LaTeX.  Try putting it in the same directory as your paper, and
% running LaTeX there.  Consult your `Local Guide' documentation or
% your system administrator to find out how LaTeX searches for input
% files.
%
% "\documentclass..." is a LaTeX2e declaration.  An error message
% "Undefined control sequence." followed by a line ending in
% "\documentclass" indicates that you have used this with an obsolete
% LaTeX installation.  Use the "\documentstyle" variant shown above.
%
% As a last resort, forget about colacl.sty and simply copy the
% following lines (uncommented, obviously) into your document before
% the "\begin{document}":
%
% \setlength\topmargin{0.0in}
% \setlength\oddsidemargin{-0.0in}
% \setlength\textheight{9.0in}
% \setlength\textwidth{6.5in}
% \setlength\columnsep{0.25in}
% \setlength\headheight{0pt}
% \setlength\headsep{0pt}
% \thispagestyle{empty}
% \pagestyle{empty}
% \flushbottom
% \twocolumn
% \sloppy
%
% Some interactions with other packages may still occur.  In order to
% remove the page number from the first page, you may have to place the
% "\thispagestyle{empty}" command immediately after "\maketitle".
%
% ----------------------------------------------------------------------
% NOTE:  Some laser printers have a serious problem printing TeX output.
% These printing devices, commonly known as "write-white" laser
% printers, tend to make characters too light.  To get around this
% problem, a darker set of fonts must be created for these devices.

% Floats (figures, tables etc.)
%
% Allow a larger proportion of the column/page to be taken up with
% floats than the standard classes.  Also discourage the creation of
% columns/pages containing only floats.

% Maximum fraction of the page that can be occupied by floats:
%
\renewcommand\topfraction{.9}
\renewcommand\bottomfraction{.5}
\renewcommand\dbltopfraction{.9}	% 2-column floats

% Minimum fraction of page that can be occupied by text:
%
\renewcommand\textfraction{.1}

% Maximum fraction of a page that can be occupied by floats before a
% separate float page is produced:
%
\renewcommand\floatpagefraction{0.9}
\renewcommand\dblfloatpagefraction{.9}	% 2-column floats

% ----------------------------------------------------------------------
%
% Since we're using two columns, lines are short and we can get away
% with less vertical space between lines, within lists and around
% various kinds of display.
%
% Normally, these parameters are set in the size option to the class
% file (standard definitions are in classes.dtx).  Here we want to
% accommodate 10pt, 11pt and 12pt, so we wrap the definitions in
% \ifcase.
