% latex2e by nr 7/3/96
% acmtrans.cls revised 4/19/96
% revised again 31-JAN-1996 (see end of file)
% revised 5-14-1997 :
% Don't use sans-serif font in categories and descriptors
% include latexsym by default
% Define longpage and shortpage
% Adjusted from the acmtrans2e.cls file to the needs of ACM TOCL by
% Marco Aiello on June 14, 2000.
% Further changes made by Frederic Goualard on Sep. 27, 2000
% to take care of the indentation problem in the bibliography
% arising without the use of the hyperref package.
% Modularization to adapt to the needs of JACM, TOCL,
% TODAES, TODS, TOGS, TOMS, AND TOPLAS, by Marco Aiello on
% June 2001.
% Here is the basic framework that is needed to convert your paper
% into ACM Transactions format and bibliographic format. For a tutorial
% introduction, see ``instructions.tex'' (compile it with LaTeX) that
% accompanies the distribution of this style file.
%
% -> \documentclass{acmtrans2m}
% -> \markboth{}{}
% takes 2 arguments and it is for the left- and right-page headers:
% the first set of braces is assigned for author's name(s)
% and
% the second set of braces is assigned for the title
% (if the title is too long, contraction may be needed
% -> \title{}
% if the title is too long, it can be separated by \\
% -> \author{}
% author1 \\ author1 affiliation
% \and
% author2 \\ author2 affiliation
% -> \begin{abstract}
% -> \end{abstract}
%
% -> \category{}{}{}
% takes 3 arguments for the Computing Reviews Classification Scheme.
% ex: \category{D.3.3}{Programming Languages}{Language Constructs and
% Features}[data types and structures]
% the last argument, in square brackets, is optional.
% -> \terms{} (ex: \terms{Human Factors, Languages})
% -> \keywords{} (in alphabetical order \keywords{document processing, sequences,
% string searching, subsequences, substrings})
% -> \begin{document}
%
% -> \begin{bottomstuff}
% similar to \thanks
% for authors' addresses; research/grant statements
% -> \end{bottomstuff}
% -> \maketitle
%
% Now you can start the body of the paper; your figures, tables and
% use all the latex constructs.
%
% -> \begin{acks}
% acknowledgements
% -> \end{acks}
%
% -> \bibliographystyle{acmtrans}
% -> \bibliography{mybib_file}
%
% ****
% If your paper has been accepted with a separate (electronic only)
% appendix, you need to add the following control sequence:
%
%
% body of appendix
%!!!!!! \appendixhead has be cut into two: \appendixhead and \elecappendix
%!!!!!! See end of file. (jtb)
%
% -> \end{document}
%
% Do not worry about the other definitions in this style file
% Remember to compile: latex, bibtex, latex latex
%
% Bibliographic cite forms needed:
%
% \cite{key}
% which produces citations with author list and year.
% eg. [Brown 1978; Jarke, et al. 1985]
% \citeA{key}
% which produces citations with only the author list.
% eg. [Brown; Jarke, et al.]
% \citeN{key}
% which produces citations with the author list and year, but
% can be used as nouns in a sentence; no brackets appear around
% the author names, but only around the year.
% eg. Shneiderman [1978] states that......
% \citeN should only be used for a single citation.
% \citeNN{refkey1,refkey2} for author [ref1year; ref2year]
% \citeyear{key}
% which produces the year information only, within brackets.
%
% Abbreviated author lists use the ``et al.'' construct.
%
% The above are examples of required ACM bibliographic cite formats needed.
% *******************
% Here is the complete list of cite forms from the chicago bibliographic style
%
% \cite{key}
% which produces citations with abbreviated author list and year.
% \citeNP{key}
% which produces citations with abbreviated author list and year.
% \citeA{key}
% which produces only the abbreviated author list.
% \citeANP{key}
% which produces only the abbreviated author list.
% \citeN{key}
% which produces the abbreviated author list and year, with only the
% year in parentheses. Use with only one citation.
% \citeyear{key}
% which produces the year information only, within parentheses.
% \citeyearNP{key}
% which produces the year information only.
%
% Abbreviated author lists use the ``et al.'' construct.
%
% `NP' means `no parentheses'

%
% this file: Modification of chicago.sty for new ACM bibliography
% style, which is similar (but not identical) to the ``Chicago'' style.
%
% chicago.sty: Style file for use with bibtex style chicago.bst, for
% bibliographies formatted according to the 13th Edition of the Chicago
% Manual of Style.
%
% 'newapa.bst' was made from 'plain.bst', 'named.bst', and 'apalike.bst',
% with lots of tweaking to make it look like APA style, along with tips
% from Young Ryu and Brian Reiser's modifications of 'apalike.bst'.
% newapa.sty formed the basis of this style, chicago.sty. Author-date
% references in newapa.bst formed the basis for chicago.bst. Chicagoa.bst
% supports annotations.
%
% Version 4 (August, 1992):
% - fixed chicago.bst and chicagoa.bst to handle long author lists in
% sorting
% - fixed chicago.bst and chicagoa.bst so that missing page numbers in
% ``article'' entries are handled correctly
% - modified chicago.sty to format entries with 2nd and subsequent lines
% indented.
%
% Citation format: (author-last-name year)
% (author-last-name and author-last-name year)
% (author-last-name et al. year)
% (author-last-name)
% author-last-name
% author-last-name (year)
% (author-last-name and author-last-name)
% (author-last-name et al.)
% (year) or (year,year)
% year or year,year
%
% Reference list ordering: alphabetical by author or whatever passes
% for author in the absence of one.
%
% This BibTeX style has support for abbreviated author lists and for
% year-only citations. This is done by having the citations
% actually look like
%
% \citeauthoryear{full-author-info}{abbrev-author-info}{year}
%
% The LaTeX style has to have the following (or similar)
%
% \let\@internalcite\cite
% \def\fullcite{\def\citeauthoryear##1##2##3{##1, ##3}\@internalcite}
% \def\fullciteA{\def\citeauthoryear##1##2##3{##1}\@internalcite}
