     7 % Changed $5 fee to $10 - Gerry

     8 % April 22nd. 2009 - Fixed 'Natbib' incompatibility problem - Gerry

     9 % April 22nd. 2009 - Fixed 'Babel' incompatibility problem - Gerry

    10 % April 22nd. 2009 - Inserted various bug-fixes and improvements - Gerry

    12 % To produce Type 1 fonts in the document plus allow for 'normal LaTeX accenting' in the critical areas;

    13 % title, author block, section-heads, confname, etc. etc. 

    14 % i.e. the whole purpose of this version update is to NOT resort to 'inelegant accent patches'.

    15 % After much research, three extra .sty packages were added to the the tail (ae, aecompl, aeguill) to solve,

    16 % in particular, the accenting problem(s). We _could_ ask authors (via instructions/sample file) to 'include' these in

    17 % the source .tex file - in the preamble - but if everything is already provided ('behind the scenes' - embedded IN the .cls)

    18 % then this is less work for authors and also makes everything appear 'vanilla'.

    19 % NOTE: all 'patchwork accenting" has been commented out (here) and is no longer 'used' in the sample .tex file (either).

    20 % Gerry June 2007

    21 %

    22 % Patch for accenting in conference name/location. Gerry May 3rd. 2007

    23 % Rule widths changed to .5, author count (>6) fixed, roll-back for Type 3 problem. Gerry March 20th. 2007

    24 % Changes made to 'modernize' the fontnames but esp. for MikTeX users V2.4/2.5 - Nov. 30th. 2006

    25 % Updated the \email definition to allow for its use inside of 'shared affiliations' - Nov. 30th. 2006

    26 % Fixed the 'section number depth value' - Nov. 30th. 2006

    27 %

    28 % Footnotes inside table cells using \minipage (Oct. 2002)

    29 % Georgia fixed bug in sub-sub-section numbering in paragraphs (July 29th. 2002)

    30 % JS/GM fix to vertical spacing before Proofs (July 30th. 2002)

    31 %

    32 % Made the Permission Statement / Conference Info / Copyright Info

    33 % 'user definable' in the source .tex file OR automatic if

    34 % not specified.

    35 %

    36 % Allowance made to switch default fonts between those systems using

    63 % Copyright (C) 1988 by Leslie Lamport

    66 %%% sig-alternate.cls is an 'ALTERNATE' document style for producing

    67 %%% two-column camera-ready pages for ACM conferences.

    68 %%% THIS FILE DOES NOT STRICTLY ADHERE TO THE SIGS (BOARD-ENDORSED)

    69 %%% PROCEEDINGS STYLE. It has been designed to produce a 'tighter'

    70 %%% paper in response to concerns over page budgets.

    71 %%% The main features of this style are:

    72 %%%

    73 %%% 1)  Two columns.

    74 %%% 2)  Side and top margins of 4.5pc, bottom margin of 6pc, column gutter of

    75 %%%     2pc, hence columns are 20pc wide and 55.5pc tall.  (6pc =3D 1in, approx)

    76 %%% 3)  First page has title information, and an extra 6pc of space at the

    77 %%%     bottom of the first column for the ACM copyright notice.

    78 %%% 4)  Text is 9pt on 10pt baselines; titles (except main) are 9pt bold.

    79 %%%

    80 %%%

    81 %%% There are a few restrictions you must observe:

    82 %%%

    83 %%% 1)  You cannot change the font size; ACM wants you to use 9pt.

    84 %%% 3)  You must start your paper with the \maketitle command.  Prior to the

    85 %%%     \maketitle you must have \title and \author commands.  If you have a

    86 %%%     \date command it will be ignored; no date appears on the paper, since

    87 %%%     the proceedings will have a date on the front cover.

    88 %%% 4)  Marginal paragraphs, tables of contents, lists of figures and tables,

    89 %%%     and page headings are all forbidden.

    90 %%% 5)  The `figure' environment will produce a figure one column wide; if you

    91 %%%     want one that is two columns wide, use `figure*'.

    92 %%%

    93 %

    94 %%% Copyright Space:

    95 %%% This style automatically reserves 1" blank space at the bottom of page 1/

    96 %%% column 1.  This space can optionally be filled with some text using the

    97 %%% \toappear{...} command.  If used, this command must be BEFORE the \maketitle

    98 %%% command.  If this command is defined AND [preprint] is on, then the

    99 %%% space is filled with the {...} text (at the bottom); otherwise, it is

   100 %%% blank.  If you use \toappearbox{...} instead of \toappear{...} then a

   101 %%% box will be drawn around the text (if [preprint] is on).

   102 %%%

   103 %%% A typical usage looks like this:

   104 %%%     \toappear{To appear in the Ninth AES Conference on Medievil Lithuanian

   105 %%%               Embalming Technique, June 1991, Alfaretta, Georgia.}

   106 %%% This will be included in the preprint, and left out of the conference

   107 %%% version.

   108 %%%

   109 %%% WARNING:

   110 %%% Some dvi-ps converters heuristically allow chars to drift from their

   111 %%% true positions a few pixels. This may be noticeable with the 9pt sans-serif

   112 %%% bold font used for section headers.

   113 %%% You may turn this hackery off via the -e option:

   114 %%%     dvips -e 0 foo.dvi >foo.ps

   115 %%%
