\typeout{Conference Style for SIGCSE for LaTeX 2e -- version of 14 June 1999}
% Place this in a file called sigcse.sty in the TeX search path.  (Placing
% it in the same directory as the paper should also work.)

% Prepared by  Susan Haller using  the AAAI style file 
% by Peter F. Patel-Schneider who liberally used the ideas of
% other style hackers, including Barbara Beeton.
% This style is NOT guaranteed to work.  It is provided in the hope
% that it will make the preparation of papers easier.
%
% There are undoubtably bugs in this style.  If you make bug fixes,
% improvements, etc.  please let me know.  My e-mail address is:
%       haller@cs.uwp.edu

% The preparation of the original AAAI style file was supported by 
% Schlumberger Palo Alto Research, AT\&T Bell Laboratories, AAAI, and
% Morgan Kaufmann Publishers.

% \pubnote added by J. Scott Penberthy

% These instructions can be modified and used in other conferences as long
% as credit to the authors and supporting agencies is retained, this notice
% is not changed, and further modification or reuse is not restricted.


% This style is NOT guaranteed to work.  It is provided in the hope
% that it will make the preparation of papers easier.
%
% NOTE: \and and \And seem to work, but \AND DOES NOT work! Don't use it. 
% I have downloaded all sorts of  LaTeX conference style files and \AND
% doesn't work properly in any of them. I have deleted the \AND definition
% from this style file.
% Susan Haller 6/16/99
%
% Papers are to be prepared as follows:
%
%       \documentstyle[sigcse]{article}
%       \title{Title}
%       \author{Author 1 \and Author 2 \\ Address line \\ Address line \And
%               Author 3 \\ Address line \\ Address line}
%       \begin{document}
%	\maketitle
%       ...
%       \bibliography{Bibliography-File}
%       \bibliographystyle{sigcse}
%       \end{document}
%
% submitted versions!!!!

% 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{Author 1 \\ {\bf Author 2} \\ ... \\ {\bf Author n} \\
%         Address line \\ ... \\ Address line}
% 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 the \documentstyle line
% where <new height> is something like 2.5in

% 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.
