% ARTICLE DOCUMENT STYLE -- Released 16 March 1988

% Copyright (C) 1988 by Leslie Lamport

% To do:
%  - Possibly move the commands related to 9pt size to a file size9.clo
%    and write the stuff to unpack both acmconf.cls and size9.clo files
%    from a single distribution file.

%%% ACMCONF is a document class for producing two-column camera-ready pages for
%%% ACM conferences, according to ACM specifications.  The main features of
%%% this class are:
%%%
%%% 1)  Two columns.
%%% 2)  Side and top margins of 4.5pc, bottom margin of 7.5pc, column gutter of
%%%     2pc, hence columns are 20pc wide and 54pc tall.  (6pc = 1in, approx)
%%% 3)  First page has title information, and an extra 4.5pc of space at the
%%%     bottom of the first column for the ACM copyright notice. (You must
%%%     use one of the commands \copyrightspace or \toappear{} to obtain this
%%%     space.)
%%% 4)  Text is 9pt on 10pt baselines; titles are 9pt bold sans-serif.
%%%     (The acmconf.sty from which acmconf.cls was derived actually uses
%%%     9pt bold roman for section titles.  Functionally, I have left this
%%%     as is.  I have added a commented out alternate defination of
%%%     \acmtitlestyle that uses sans-serif)  --DAB
%%%
%%% This document class supports a [preprint] class option that allows you
%%% to run off a copy for a preprint -- with page numbers, "to appear"
%%% information, and so forth. This is documented below.

%%% There are a few restrictions you must observe:
%%%
%%% 1)  You cannot change the font size; ACM wants you to use 9pt.
%%% 3)  You must start your paper with the \maketitle command.  Prior to the
%%%     \maketitle you must have \title and \author commands.  If you have a
%%%     \date command it will be ignored; no date appears on the paper, since
%%%     the proceedings will have a date on the front cover.
%%%     Optionally, you may have an \affiliation command with text, such
%%%     as company or university name and address, that will be centered
%%%     just below the author(s).
%%% 4)  Marginal paragraphs, tables of contents, lists of figures and tables,
%%%     and page headings are all forbidden.
%%% 5)  The `figure' environment will produce a figure one column wide; if you
%%%     want one that is two columns wide, use `figure*'.  Ditto for the
%%%     `table' and `table*' environments.
%%%
%%% Page Headings:
%%% Normally, \pagestyle commands are ignored --- pages have no headings or
%%% numbers. ACM will number the pages for you when they are inserted into the
%%% proceedings (you should put page numbers on the BACK of each page, though,
%%% in case someone drops your paper on the floor).
%%%
%%% If the [preprint] option is present, then \pagestyle commands are obeyed,
%%% and the default is \pagestyle{plain}. The [twoside] option is also
%%% useful when using headers.
%%%
%%% The [draft] and [final] options as used in the article class are also
%%% supported.
%%%
%%%
%%% Copyright Space:
%%% You leave space at the bottom of page 1/column 1 one with the
%%% \copyrightspace command.  Alternatively, you can use the
%%% \toappear{...} command.  Normally, this turns into an unnumbered
%%% footnote 4.5pc high.  If [preprint] is on, then this space is
%%% filled with the {...} text; otherwise, it's blank. You must put
%%% one of these commands in the text of page 1/column 1 *after* all the
%%% other footnotes that go on page1/column 1, of course.
%%%
%%% A typical usage looks like this:
%%%     \toappear{To appear in the Ninth AES Conference on Midevil Lithuanian
%%%               Embalming Technique, June 1991, Alfaretta, Georgia.
%%%               Also available as Technical Report CMU-CS-91-119,
%%%               Cranberry Melon School of Cucumber Science.}
%%% This will be included in the preprint, and left out of the conference
%%% version.
%%%
%%% Acmconf defines two useful conditionals.
%%% - \ifacmconf{true-stuff}{false-stuff}
%%%   expands to true-stuff.
%%% - \ifpreprint true-stuff \else else-stuff \fi
%%%   expands to true-stuff if the [preprint] option is being used,
%%%   otherwise it expands to else-stuff.
%%% \ifacmconf is a latex command; \ifpreprint is a real latex conditional.
%%%
%%% WARNING:
%%% Some dvi-ps converters heuristically allow chars to drift from their
%%% true positions a few pixels. This loses noticeably with the 9pt sans-serif
%%% bold font used for section headers. You turn this hackery off in our
%%% dvi-ps converters with the -e option:
%%%     dvips -e 0 foo.dvi >foo.ps
