1 % ACMCONF DOCUMENT STYLE - Updated 10 April 1995.
3 % This is a patched version of the 5 April 1993 release. No stylistic
4 % changes have been made; it should produce output identical to the 1993
5 % release if that release worked properly on your system. A LaTeX2e patch
6 % has been added for systems having problems with the section header font.
8 % If you get an error message similar to
10 % ! Undefined control sequence.

15 % Modification of Traub/Shivers version by Kevin Theobald, McGill
16 % University. New version has automatic copyright space, option
17 % for box around "to appear" entry, and style option to indent
18 % first paragraph after subheadings. Released 5 April 1993.
20 % To use: install in reachable directory (one contained in TEXINPUTS
21 % environment variable); use \documentstyle[<options>]{acmconf}

25 % ARTICLE DOCUMENT STYLE -- Released 16 March 1988
26 % for LaTeX version 2.09
27 % Copyright (C) 1988 by Leslie Lamport
29 %%% ACMCONF is a document style for producing two-column camera-ready pages for
30 %%% ACM conferences, according to ACM specifications. The main features of
34 %%% 2) Side and top margins of 4.5pc, bottom margin of 6pc, column gutter of
35 %%% 2pc, hence columns are 20pc wide and 55.5pc tall. (6pc = 1in, approx)
36 %%% 3) First page has title information, and an extra 6pc of space at the
37 %%% bottom of the first column for the ACM copyright notice.
38 %%% 4) Text is 9pt on 10pt baselines; titles (except main) are 9pt bold.
40 %%% This document style supports a [preprint] style option that allows
41 %%% you to run off a copy for a preprint -- with page numbers, "to
42 %%% appear" information, and so forth. This is documented below.
44 %%% This document style also supports a [secindent] style option which
45 %%% causes paragraphs following (sub)section heads to be indented like
46 %%% the others. (Added by KBT)
48 %%% There are a few restrictions you must observe:
50 %%% 1) You cannot change the font size; ACM wants you to use 9pt.
51 %%% 3) You must start your paper with the \maketitle command. Prior to the
52 %%% \maketitle you must have \title and \author commands. If you have a
53 %%% \date command it will be ignored; no date appears on the paper, since
54 %%% the proceedings will have a date on the front cover.
55 %%% 4) Marginal paragraphs, tables of contents, lists of figures and tables,
56 %%% and page headings are all forbidden.
57 %%% 5) The `figure' environment will produce a figure one column wide; if you
58 %%% want one that is two columns wide, use `figure*'.
61 %%% Normally, \pagestyle commands are ignored --- pages have no headings or
62 %%% numbers. ACM will number the pages for you when they are inserted into the
63 %%% proceedings (you should put page numbers on the BACK of each page, though,
64 %%% in case someone drops your paper on the floor).
66 %%% If the [preprint] option is present, then \pagestyle commands are obeyed,
67 %%% and the default is \pagestyle{plain}. All pages (including the first)
68 %%% are numbered. (This is useful if you want to make a reprint version
69 %%% of your paper, with page numbering identical to the conference
70 %%% proceedings. In such a case, you may need to insert the command
71 %%% \setcounter{page}{...} before \maketitle.) The [twoside] option is
72 %%% also useful when using headers.
75 %%% This style automatically leaves 1" blank space at the bottom of page 1/
76 %%% column 1. This space can optionally be filled with some text using the
77 %%% \toappear{...} command. If used, this command must be BEFORE the \maketitle
78 %%% command. If this command is defined AND [preprint] is on, then the
79 %%% space is filled with the {...} text (at the bottom); otherwise, it is
80 %%% blank. If you use \toappearbox{...} instead of \toappear{...} then a
81 %%% box will be drawn around the text (if [preprint] is on).
83 %%% A typical usage looks like this:
84 %%% \toappear{To appear in the Ninth AES Conference on Medievil Lithuanian
85 %%% Embalming Technique, June 1991, Alfaretta, Georgia.}
86 %%% This will be included in the preprint, and left out of the conference
89 %%% Acmconf defines two useful conditionals.
90 %%% - \ifacmconf{true-stuff}{false-stuff}
91 %%% expands to true-stuff.
92 %%% - \ifpreprint true-stuff \else else-stuff \fi
93 %%% expands to true-stuff if the [preprint] option is being used,
94 %%% otherwise it expands to else-stuff.
95 %%% \ifacmconf is a latex command; \ifpreprint is a real latex conditional.
98 %%% Some dvi-ps converters heuristically allow chars to drift from their
99 %%% true positions a few pixels. This loses noticeably with the 9pt sans-serif
100 %%% bold font used for section headers. You turn this hackery off in our
101 %%% dvi-ps converters with the -e option:
102 %%% dvips -e 0 foo.dvi >foo.ps
