  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

  65 %
  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 %%%

1441 % The following section (i.e. 3 .sty inclusions) was added in May 2007 so as to fix the problems that many
1442 % authors were having with accents. Sometimes accents would occur, but the letter-character would be of a different
1443 % font. Conversely the letter-character font would be correct but, e.g. a 'bar' would appear superimposed on the
1444 % character instead of, say, an unlaut/diaresis. Sometimes the letter-character would NOT appear at all.
1445 % Using [T1]{fontenc} outright was not an option as this caused 99% of the authors to 'produce' a Type-3 (bitmapped)
1446 % PDF file - useless for production.
1447 %
1448 % For proper (font) accenting we NEED these packages to be part of the .cls file i.e. 'ae', 'aecompl' and 'aeguil'

1500 %% This is file `aeguill.sty'
1501 % This file gives french guillemets (and not guillemots!)
1502 % built with the Polish CMR fonts (default), WNCYR fonts, the LASY fonts
1503 % or with the EC fonts.
1504 % This is useful in conjunction with the ae package
1505 % (this package loads the ae package in case it has not been loaded)
1506 %  and with or without the french(le) package.
1507 %
1508 % In order to get the guillemets, it is necessary to either type
1509 % \guillemotleft and \guillemotright, or to use an 8 bit encoding
1510 % (such as ISO-Latin1) which selects these two commands,
1511 % or, if you use the french package (but not the frenchle package),
1512 % to type << or >>.
1513 %
1514 % By default, you get the Polish CMR guillemets; if this package is loaded
1515 % with the `cm' option, you get the LASY guillemets; with `ec,' you
1516 % get the EC guillemets, and with `cyr,' you get the cyrillic guillemets.
1517 %
1518 % In verbatim mode, you always get the EC/TT guillemets.
1519 %
1520 % The default option is interesting in conjunction with PDF,
1521 % because there is a Type 1 version of the Polish CMR fonts
1522 % and these guillemets are very close in shape to the EC guillemets.
1523 % There are no free Type 1 versions of the EC fonts.
1524 %
1525 % Support for Polish CMR guillemets was kindly provided by
1526 % Rolf Niepraschk <niepraschk@ptb.de> in version 0.99 (2000/05/22).
1527 % Bernd Raichle provided extensive simplifications to the code
