17% To produce Type 1 fonts in the document plus allow for 'normal LaTeX accenting' in the critical areas;
18% title, author block, section-heads, confname, etc. etc.
19% i.e. the whole purpose of this version update is to NOT resort to 'inelegant accent patches'.
20% After much research, three extra .sty packages were added to the the tail (ae, aecompl, aeguill) to solve,
21% in particular, the accenting problem(s). We _could_ ask authors (via instructions/sample file) to 'include' these in
22% the source .tex file - in the preamble - but if everything is already provided ('behind the scenes' - embedded IN the .cls)
23% then this is less work for authors and also makes everything appear 'vanilla'.
24% NOTE: all 'patchwork accenting" has been commented out (here) and is no longer 'used' in the sample .tex file (either).

71%%% sig-alternate.cls is an 'ALTERNATE' document style for producing
72%%% two-column camera-ready pages for ACM conferences.
73%%% THIS FILE DOES NOT STRICTLY ADHERE TO THE SIGS (BOARD-ENDORSED)
74%%% PROCEEDINGS STYLE. It has been designed to produce a 'tighter'
75%%% paper in response to concerns over page budgets.
76%%% The main features of this style are:
77%%%
78%%% 1) Two columns.
79%%% 2) Side and top margins of 4.5pc, bottom margin of 6pc, column gutter of
80%%% 2pc, hence columns are 20pc wide and 55.5pc tall. (6pc =3D 1in, approx)
81%%% 3) First page has title information, and an extra 6pc of space at the
82%%% bottom of the first column for the ACM copyright notice.
83%%% 4) Text is 9pt on 10pt baselines; titles (except main) are 9pt bold.
84%%%
85%%%
86%%% There are a few restrictions you must observe:
87%%%
88%%% 1) You cannot change the font size; ACM wants you to use 9pt.
89%%% 3) You must start your paper with the \maketitle command. Prior to the
90%%% \maketitle you must have \title and \author commands. If you have a
91%%% \date command it will be ignored; no date appears on the paper, since
92%%% the proceedings will have a date on the front cover.
93%%% 4) Marginal paragraphs, tables of contents, lists of figures and tables,
94%%% and page headings are all forbidden.
95%%% 5) The `figure' environment will produce a figure one column wide; if you
96%%% want one that is two columns wide, use `figure*'.
97%%%
98%
99%%% Copyright Space:
100%%% This style automatically reserves 1" blank space at the bottom of page 1/
101%%% column 1. This space can optionally be filled with some text using the
102%%% \toappear{...} command. If used, this command must be BEFORE the \maketitle
103%%% command. If this command is defined AND [preprint] is on, then the
104%%% space is filled with the {...} text (at the bottom); otherwise, it is
105%%% blank. If you use \toappearbox{...} instead of \toappear{...} then a
106%%% box will be drawn around the text (if [preprint] is on).
107%%%
108%%% A typical usage looks like this:
109%%% \toappear{To appear in the Ninth AES Conference on Medievil Lithuanian
110%%% Embalming Technique, June 1991, Alfaretta, Georgia.}
111%%% This will be included in the preprint, and left out of the conference
112%%% version.
113%%%
114%%% WARNING:
115%%% Some dvi-ps converters heuristically allow chars to drift from their
116%%% true positions a few pixels. This may be noticeable with the 9pt sans-serif
117%%% bold font used for section headers.
118%%% You may turn this hackery off via the -e option:
119%%% dvips -e 0 foo.dvi >foo.ps

1532%
1533% The following section (i.e. 3 .sty inclusions) was added in May 2007 so as to fix the problems that many
1534% authors were having with accents. Sometimes accents would occur, but the letter-character would be of a different
1535% font. Conversely the letter-character font would be correct but, e.g. a 'bar' would appear superimposed on the
1536% character instead of, say, an unlaut/diaresis. Sometimes the letter-character would NOT appear at all.
1537% Using [T1]{fontenc} outright was not an option as this caused 99% of the authors to 'produce' a Type-3 (bitmapped)
1538% PDF file - useless for production.
1539%
1540% For proper (font) accenting we NEED these packages to be part of the .cls file i.e. 'ae', 'aecompl' and 'aeguil'

1593%% This is file `aeguill.sty'
1594% This file gives french guillemets (and not guillemots!)
1595% built with the Polish CMR fonts (default), WNCYR fonts, the LASY fonts
1596% or with the EC fonts.
1597% This is useful in conjunction with the ae package
1598% (this package loads the ae package in case it has not been loaded)
1599% and with or without the french(le) package.
1600%
1601% In order to get the guillemets, it is necessary to either type
1602% \guillemotleft and \guillemotright, or to use an 8 bit encoding
1603% (such as ISO-Latin1) which selects these two commands,
1604% or, if you use the french package (but not the frenchle package),
1605% to type << or >>.
1606%
1607% By default, you get the Polish CMR guillemets; if this package is loaded
1608% with the `cm' option, you get the LASY guillemets; with `ec,' you
1609% get the EC guillemets, and with `cyr,' you get the cyrillic guillemets.
1610%
1611% In verbatim mode, you always get the EC/TT guillemets.
1612%
1613% The default option is interesting in conjunction with PDF,
1614% because there is a Type 1 version of the Polish CMR fonts
1615% and these guillemets are very close in shape to the EC guillemets.
1616% There are no free Type 1 versions of the EC fonts.
1617%
1618% Support for Polish CMR guillemets was kindly provided by
1619% Rolf Niepraschk <niepraschk@ptb.de> in version 0.99 (2000/05/22).
1620% Bernd Raichle provided extensive simplifications to the code
1621% for version 1.00.
