% ACMCONF DOCUMENT CLASS% adapted from ARTICLE document style by Ken Traub% Hacked for [preprint] option by Olin Shivers 4/91% Fixed up for LaTeX version 2e [compatibility mode] by Peter Lee 10/9% (with help from Simon Peyton Jones)% Converted to a LaTeX2e document class by David A. Berson 11/94%% ARTICLE DOCUMENT STYLE -- Released 16 March 1988% for LaTeX version 2.09% 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\NeedsTeXFormat{LaTeX2e}\ProvidesClass{acmconf}[1994/11/27 Alternative LaTeX document class]\typeout{Bugs to berson@cs.pitt.edu}%% Define the conditionals and command for the options.%\newif\if@acmconf\@acmconftrue\long\def\ifacmconf#1#2{\if@acmconf#1\else#2\fi}\newif\ifpreprint%% Declare and process the options%\DeclareOption{draft}{\PassOptionsToClass{draft}{article}}\DeclareOption{final}{\PassOptionsToClass{final}{article}}\DeclareOption{twocolumn}{\PassOptionsToClass{twocolumn}{article}}\DeclareOption{twoside}{\PassOptionsToClass{twoside}{article}}\DeclareOption{preprint}{\preprintfalse}%\DeclareOption{preprint}{\preprinttrue}%% Let them off with just a warning for any other option%\DeclareOption*{\ClassWarningNoLine{acmconf}{Unknown option `\CurrentOption'}}%\DeclareOption*{\ClassError{acmconf}% {The `\CurrentOption' option is not supported}% {Remove the `\CurrentOption' option from the% \protect\documentclass\space line.}}\ExecuteOptions{twocolumn}\ProcessOptions%% This class simply modifies a few behaviors of the article class,% so load it now%\LoadClass{article}%**********************************************************************%% The following commands would normally be in a file such as% size9.clo for the article class.
