     8 % Adjusted from the acmtrans2e.cls file to the needs of ACM TOCL by

     9 % Marco Aiello on June 14, 2000.

    10 % Further changes made by Frederic Goualard on Sep. 27, 2000

    11 % to take care of the indentation problem in the bibliography 

    12 % arising without the use of the hyperref package.

    13 % Modularization to adapt to the needs of ALL Transactions of the ACM, 

    14 % and the Journal of the ACM, by Marco Aiello on June and October 2001.

    15 % Here is the basic framework that is needed to convert your paper 

    16 % into ACM Transactions format and bibliographic format.  For a tutorial

    17 % introduction, see ``instructions.tex'' (compile it with LaTeX) that

    18 % accompanies the distribution of this style file.

    19 %

    20 %  -> \documentclass{acmtrans2m}

    21 %  -> \markboth{}{}

    22 %         takes 2 arguments and it is for the left- and right-page headers:

    23 %         the first set of braces is assigned for author's name(s) 

    24 %         and

    25 %         the second set of braces is assigned for the title 

    26 %             (if the title is too long, contraction may be needed

    27 %  -> \title{}

    28 %         if the title is too long, it can be separated by \\

    29 %  -> \author{}

    30 %         author1 \\ author1 affiliation

    31 %         \and

    32 %         author2 \\ author2 affiliation

    33 %  -> \begin{abstract}

    34 %  -> \end{abstract}

    35 %

    36 %  -> \category{}{}{}

    37 %         takes 3 arguments for the Computing Reviews Classification Scheme.

    38 %         ex: \category{D.3.3}{Programming Languages}{Language Constructs and 

    39 %                   Features}[data types and structures]

    40 %                   the last argument, in square brackets, is optional.

    41 %  -> \terms{} (ex: \terms{Human Factors, Languages})

    42 %  -> \keywords{} (in alphabetical order \keywords{document processing, sequences, 

    43 %                      string searching, subsequences, substrings})

    44 %  -> \begin{document}

    45 %

    46 %  -> \begin{bottomstuff}

    47 %          similar to \thanks     

    48 %          for authors' addresses; research/grant statements

    49 %  -> \end{bottomstuff}

    50 %  -> \maketitle

    51 %

    52 %     Now you can start the body of the paper; your figures, tables and 

    53 %          use all the latex constructs.

    54 %

    55 %  -> \begin{acks}

    56 %          acknowledgements

    57 %  -> \end{acks}

    60 %  -> \bibliography{mybib_file}

    62 %     ****

    63 %     If your paper has been accepted with a separate (electronic only)

    64 %        appendix, you need to add the following control sequence:

    65 %

    66 %

    67 %       body of appendix 

    68 %!!!!!! \appendixhead has be cut into two: \appendixhead and \elecappendix

    69 %!!!!!! See end of file. (jtb)

    70 %

    71 %  -> \end{document}

    72 %

    73 % Do not worry about the other definitions in this style file

    74 % Remember to compile: latex, bibtex, latex latex

    75 %

    76 % Bibliographic cite forms needed:

    77 %

    78 %  \cite{key}

    79 %    which produces citations with author list and year.

    80 %    eg. [Brown 1978; Jarke, et al. 1985]

    81 %  \citeA{key}

    82 %    which produces citations with only the author list.

    83 %    eg. [Brown; Jarke, et al.]

    84 %  \citeN{key}

    85 %    which produces citations with the author list and year, but

    86 %    can be used as nouns in a sentence; no brackets appear around

    87 %    the author names, but only around the year.

    88 %      eg. Shneiderman [1978] states that......

    89 %    \citeN should only be used for a single citation.

    90 %    \citeNN{refkey1,refkey2} for author [ref1year; ref2year]

    91 %    \citeyear{key}

    92 %        which produces the year information only, within brackets.

    93 %

    94 % Abbreviated author lists use the ``et al.'' construct.

    95 %

    96 % The above are examples of required ACM bibliographic cite formats needed.

    97 % *******************

    98 % Here is the complete list of cite forms from the chicago bibliographic style

    99 %

   100 %  \cite{key}

   101 %    which produces citations with abbreviated author list and year.

   102 %  \citeNP{key}

   103 %    which produces citations with abbreviated author list and year.

   104 %  \citeA{key}

   105 %    which produces only the abbreviated author list.

   106 %  \citeANP{key}

   107 %    which produces only the abbreviated author list.

   108 %  \citeN{key}

   109 %    which produces the abbreviated author list and year, with only the

   110 %    year in parentheses. Use with only one citation.

   111 %  \citeyear{key}

   112 %    which produces the year information only, within parentheses.

   113 %  \citeyearNP{key}

   114 %    which produces the year information only.

   115 %

   116 % Abbreviated author lists use the ``et al.'' construct.

   118 % `NP' means `no parentheses'
