-% ACMCONF DOCUMENT STYLE - Updated 17 August 1995.
-%
-% This is a patched version of the 5 April 1993 release.  No stylistic changes
-% have been made; it should produce output identical to the 1993 release if
-% that release worked properly on your system.  A LaTeX2e patch has been added
-% for systems having problems with the section header font.  There is also a
-% macro for producing an ACM copyright notice and a box with reprint info.
-%
-% If you get an error message similar to
-%
-% ! Undefined control sequence.
-% l.165 \font\ninsfb = cmssbx10\@ptscale
-%
-% then see the comments beginning on line 173 (look for "DIAGNOSTICS").
-%-----------------------------------------------------------------------
-%	Modification of Traub/Shivers version by Kevin Theobald, McGill
-%	University.  New version has automatic copyright space, option
-%	for box around "to appear" entry, and style option to indent
-%	first paragraph after subheadings.  Released 5 April 1993.
-%
-%	To use: install in reachable directory (one contained in TEXINPUTS
-%	environment variable); use \documentstyle[<options>]{acmconf}

-%    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 6pc, column gutter of
-%%%     2pc, hence columns are 20pc wide and 55.5pc tall.  (6pc = 1in, approx)
-%%% 3)  First page has title information, and an extra 6pc of space at the
-%%%     bottom of the first column for the ACM copyright notice.
-%%% 4)  Text is 9pt on 10pt baselines; titles (except main) are 9pt bold.
-%%%
-%%% 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.
-%%%
-%%% This document style also supports a [secindent] style option which
-%%% causes paragraphs following (sub)section heads to be indented like
-%%% the others.	 (Added by KBT)
-%%%
-%%% Finally, the macro \acmcopy{y} (y is year, e.g., 1995) prints the text of
-%%% an ACM copyright notice.  This is useful for making a copy of the paper on
-%%% the author's FTP site (ACM requires a copyright notice).  (Added by KBT)
-%%%
-%%% 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, in
-%%% light pencil, 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}.  All pages (including the first)
-%%% are numbered.  (This is useful if you want to make a reprint version
-%%% of your paper, with page numbering identical to the conference
-%%% proceedings.  In such a case, you may need to insert the command
-%%% \setcounter{page}{...} before \maketitle.) The [twoside] option is
-%%% also useful when using headers.
-%%%
-%%% Copyright Space:
-%%% This style automatically leaves 1" blank space at the bottom of page 1/
-%%% column 1.  This space can optionally be filled with some text using the
-%%% \toappear{...} command.  If used, this command must be BEFORE the \maketitle
-%%% command.  If this command is defined AND [preprint] is on, then the
-%%% space is filled with the {...} text (at the bottom); otherwise, it is
-%%% blank.  If you use \toappearbox{...} instead of \toappear{...} then a
-%%% box will be drawn around the text (if [preprint] is on).
-%%%
-%%% A typical usage looks like this:
-%%%     \toappear{To appear in the Ninth AES Conference on Medievil Lithuanian
-%%%               Embalming Technique, June 1991, Alfaretta, Georgia.}
-%%% 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
