% adapted from ARTICLE document style by Ken Traub
% Hacked for [preprint] option by Olin Shivers 4/91

% ARTICLE DOCUMENT STYLE -- Released 16 March 1988
% for LaTeX version 2.09
% Copyright (C) 1988 by Leslie Lamport
%%% ACMCONF is a document style for producing two-column camera-ready pages for
%%% ACM conferences, according to ACM specifications. The main features of
%%% this style 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.
%%% 4) Text is 9pt on 10pt baselines; titles are 9pt bold sans-serif.
%%%
%%% This document style supports a [preprint] style 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.
%%% 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*'.
%%%
%%% 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.
%%%
%%%
%%% Copyright Space:
%%% You leave space at the bottom of page 1/column 1 one with 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
%%% this command 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
