n@1118: % To produce Type 1 fonts in the document plus allow for 'normal LaTeX accenting' in the critical areas;
n@1118: % title, author block, section-heads, confname, etc. etc. 
n@1118: % i.e. the whole purpose of this version update is to NOT resort to 'inelegant accent patches'.
n@1118: % After much research, three extra .sty packages were added to the the tail (ae, aecompl, aeguill) to solve,
n@1118: % in particular, the accenting problem(s). We _could_ ask authors (via instructions/sample file) to 'include' these in
n@1118: % the source .tex file - in the preamble - but if everything is already provided ('behind the scenes' - embedded IN the .cls)
n@1118: % then this is less work for authors and also makes everything appear 'vanilla'.
n@1118: % NOTE: all 'patchwork accenting" has been commented out (here) and is no longer 'used' in the sample .tex file (either).

n@1118: %    adapted from ARTICLE document style by Ken Traub, Olin Shivers
n@1118: %    also using elements of esub2acm.cls
n@1118: % HEAVILY MODIFIED, SUBSEQUENTLY, BY GERRY MURRAY 2000
n@1118: % ARTICLE DOCUMENT STYLE -- Released 16 March 1988
n@1118: %    for LaTeX version 2.09
n@1118: % Copyright (C) 1988 by Leslie Lamport
n@1118: %
n@1118: %
n@1118: %%% sig-alternate.cls is an 'ALTERNATE' document style for producing
n@1118: %%% two-column camera-ready pages for ACM conferences.
n@1118: %%% THIS FILE DOES NOT STRICTLY ADHERE TO THE SIGS (BOARD-ENDORSED)
n@1118: %%% PROCEEDINGS STYLE. It has been designed to produce a 'tighter'
n@1118: %%% paper in response to concerns over page budgets.
n@1118: %%% The main features of this style are:
n@1118: %%%
n@1118: %%% 1)  Two columns.
n@1118: %%% 2)  Side and top margins of 4.5pc, bottom margin of 6pc, column gutter of
n@1118: %%%     2pc, hence columns are 20pc wide and 55.5pc tall.  (6pc =3D 1in, approx)
n@1118: %%% 3)  First page has title information, and an extra 6pc of space at the
n@1118: %%%     bottom of the first column for the ACM copyright notice.
n@1118: %%% 4)  Text is 9pt on 10pt baselines; titles (except main) are 9pt bold.
n@1118: %%%
n@1118: %%%
n@1118: %%% There are a few restrictions you must observe:
n@1118: %%%
n@1118: %%% 1)  You cannot change the font size; ACM wants you to use 9pt.
n@1118: %%% 3)  You must start your paper with the \maketitle command.  Prior to the
n@1118: %%%     \maketitle you must have \title and \author commands.  If you have a
n@1118: %%%     \date command it will be ignored; no date appears on the paper, since
n@1118: %%%     the proceedings will have a date on the front cover.
n@1118: %%% 4)  Marginal paragraphs, tables of contents, lists of figures and tables,
n@1118: %%%     and page headings are all forbidden.
n@1118: %%% 5)  The `figure' environment will produce a figure one column wide; if you
n@1118: %%%     want one that is two columns wide, use `figure*'.
n@1118: %%%
n@1118: %
n@1118: %%% Copyright Space:
n@1118: %%% This style automatically reserves 1" blank space at the bottom of page 1/
n@1118: %%% column 1.  This space can optionally be filled with some text using the
n@1118: %%% \toappear{...} command.  If used, this command must be BEFORE the \maketitle
n@1118: %%% command.  If this command is defined AND [preprint] is on, then the
n@1118: %%% space is filled with the {...} text (at the bottom); otherwise, it is
n@1118: %%% blank.  If you use \toappearbox{...} instead of \toappear{...} then a
n@1118: %%% box will be drawn around the text (if [preprint] is on).
n@1118: %%%
n@1118: %%% A typical usage looks like this:
n@1118: %%%     \toappear{To appear in the Ninth AES Conference on Medievil Lithuanian
n@1118: %%%               Embalming Technique, June 1991, Alfaretta, Georgia.}
n@1118: %%% This will be included in the preprint, and left out of the conference
n@1118: %%% version.
n@1118: %%%
n@1118: %%% WARNING:
n@1118: %%% Some dvi-ps converters heuristically allow chars to drift from their
n@1118: %%% true positions a few pixels. This may be noticeable with the 9pt sans-serif
n@1118: %%% bold font used for section headers.
n@1118: %%% You may turn this hackery off via the -e option:
n@1118: %%%     dvips -e 0 foo.dvi >foo.ps

n@1118: % The following section (i.e. 3 .sty inclusions) was added in May 2007 so as to fix the problems that many
n@1118: % authors were having with accents. Sometimes accents would occur, but the letter-character would be of a different
n@1118: % font. Conversely the letter-character font would be correct but, e.g. a 'bar' would appear superimposed on the
n@1118: % character instead of, say, an unlaut/diaresis. Sometimes the letter-character would NOT appear at all.
n@1118: % Using [T1]{fontenc} outright was not an option as this caused 99% of the authors to 'produce' a Type-3 (bitmapped)
n@1118: % PDF file - useless for production. 
n@1118: %
n@1118: % For proper (font) accenting we NEED these packages to be part of the .cls file i.e. 'ae', 'aecompl' and 'aeguil'

n@1118: % built with the Polish CMR fonts (default), WNCYR fonts, the LASY fonts 
n@1118: % or with the EC fonts. 
n@1118: % This is useful in conjunction with the ae package
n@1118: % (this package loads the ae package in case it has not been loaded)
n@1118: %  and with or without the french(le) package.
n@1118: %
n@1118: % In order to get the guillemets, it is necessary to either type
n@1118: % \guillemotleft and \guillemotright, or to use an 8 bit encoding
n@1118: % (such as ISO-Latin1) which selects these two commands, 
n@1118: % or, if you use the french package (but not the frenchle package), 
n@1118: % to type << or >>.
n@1118: %
n@1118: % By default, you get the Polish CMR guillemets; if this package is loaded
n@1118: % with the `cm' option, you get the LASY guillemets; with `ec,' you
n@1118: % get the EC guillemets, and with `cyr,' you get the cyrillic guillemets.
n@1118: %
n@1118: % In verbatim mode, you always get the EC/TT guillemets.
n@1118: %
n@1118: % The default option is interesting in conjunction with PDF,
n@1118: % because there is a Type 1 version of the Polish CMR fonts
n@1118: % and these guillemets are very close in shape to the EC guillemets.
n@1118: % There are no free Type 1 versions of the EC fonts.
n@1118: %
n@1118: % Support for Polish CMR guillemets was kindly provided by
