% NELS 2003 LaTeX class

% For the Proceedings of the North Eastern Linguistics Society Based
% on the 2003 style sheet instructions.  Written by Uli Sauerland.  A
% few parts were taken from Alexis Dimitriadis's salt.cls.


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% REQUIREMENTS:
%
% TO USE THIS CLASS YOU MUST HAVE THE MEMOIR CLASS, AND THE NATBIB
% PACKAGE INSTALLED. BOTH ARE AVAILABLE FROM CTAN (memoir.cls AND
% natbib.sty).
% 
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 
% 
% USAGE:
% 
% Use this file INSTEAD of the `memoir' class:
% \documentclass{nels}
%
% This class definition does not provide an example environment.
% It does call natbib.
%
% TITLE BLOCK DIRECTIONS:
%
% To format your title and name, use the standard commands \title{...},
% \author{...}, the non-standard \affiliation{...}, and \maketitle.
%
% Use the standard command \thanks{...} if you want to provide an
% acknowledgement footnote in the title. 

% Most NELS proceedings papers use 14pt leading, which seems to be the
% default of Microsoft Word with Times Roman.  To my eyes, Latex's
% 14.5pt leading is more readable, so I left this unchanged.

% PAGE HEADERS: Author's name(s) and the title are automatically put
% in the headers.  However, if the authors' names or the title are
% longer than 50 characters, you should enter a shorter version below,
% and uncomment the line.
% 
% \markboth{SHORT NAMES}{SHORT TITLE}

% PAGE NUMBERS AND REFERENCE: NELS proceedings papers have a small
% reference on the title page.  Usually the editors add this and the
% page numbers themselves.  But, for electronic distribution, I at
% least want to put this in.  Therefore, I add reference and page
% number by default.  In the preamble, you must set the starting page
% number with the following command.
%
% \setcounter{page}{xxx}
% 
% For the submitted version, my experience has been in the past that
% the editors were happy to have me put in the page numbers.
% They did add the reference on their own though.  Here are preamble
% commands to get rid of the page numbers and the reference or just 
% the reference:
% - Neither page numbers nor the reference
%   \nopagenumbers
% - Page numbers, but no reference
%   \makeoddfoot{title}{}{}{}
%

% 8. EXAMPLES
% 
% Use your own example macros: Each example style must have its margins
% adjusted in a different way.  
%
% ``Example numbers should be at the left hand margin, not indented. Examples
% should start at the 0.5 inch position, i.e. in line with your indented
% paragraphs. In the case of several examples given under the same example
% number, we suggest indenting to 0.5 inches, giving the subexample letter
% (usually a., b., c., etc.), then indenting another 0.25 inches''

% 9. BIBLIOGRAPHY

% The following relies on the natbib-package.  You still need to 
% declare a bibliography style, e.g. \bibliographystyle{linquiry2.bst}.
