-=============================================================================
-
-CHANGE HISTORY:
-
-v1.1.1		Changed copyright space to 1.5 inches.
-
-v1.1.0		Added \keywords and \estpages commands.
-		Disabled \passport command.
-		Changed \acmcategory/\acmformat commands to \category/\format.
-
-v1.0.0		Added preprint option.
-		Changed \acmpassport command to \passport.
-
-v0.9.0		Added \teaser command to allow pictures placed between the
-		title block and the start of the text.
-		Added \titlespace and \teaserspace to control spacing
-		between title block, teaser, and text.
-
-v0.8.3		Added \sectionfont command.
-		Added singlespace and doublespace options
-		Lots of internal changes in implementation
-
-v0.8.1		Made copyright space 1 inch
-
-v0.8.0		I really hated having to use the \acmopening command to
-		instead of \maketitle and the abstract environment in order
-		to get the abstract to appear on both the cover page and
-		in the paper.  I finally figured out how to modify the
-		abstract environment to store its contents for use on
-		the cover page, so the \acmopening command has now
-		been eliminated.
-
-v0.7.0		Added `widereview' option for one-column, double-spaced,
-		  12-point review papers
-
-v0.6.3		Fixed one-column mode
-		Put page numbers back in for review papers
-
-v0.6.2		Fixed missing affiliation in title block
-
-v0.6.1		Made titles bold
-		Minor corrections in user's guide

-% \section{Introduction}
-%
-% This document describes the |siggraph| document class, for use with \LaTeXe{}.
-% It is intended as a replacement for the various versions of the old
-% |siggraph.sty| file that have been floating around for years.
-% It loads in the |article| class and modifies several parameters
-% to comply with the layout specifications for a paper submitted to
-% the ACM Siggraph conference.
-% Currently, these specifications are:
-% \begin{mylist}
-%   \label{layoutlist}
-%   \item $\frac{3}{4}$ inch margins on top and sides, 1 inch margin on bottom
-%   \item two column mode with 2 pica column separation
-%   \item space for copyright is 1.5 inch
-% \changes{v0.8.1}{1995/03/22}{Made copyright space 1 inch}
-% \changes{v1.1.1}{1996/01/17}{Made copyright space 1.5 inch}
-%   \item 9 point type on 10 point baselines
-%   \item no page numbers
-% \changes{v0.6.3}{1995/01/06}{Put page numbers back in for review option}
-% \end{mylist}
-% Also set by the class but not part of the siggraph specifications are:
-% \begin{mylist}
-% \changes{v0.6.1}{1994/12/26}{Made titles bold}
-%   \item titles and section headings are bold sans serif
-%   \item 1 em paragraph indentation
-%   \item |flushbottom| mode
-% \end{mylist}
-%
-% The class also allows the user to specify whether the paper is being
-% submitted for blind review or as a final, camera-ready document.
-% When review mode is specified, it will automatically generate a
-% cover sheet for the paper, modify the title block on the first page
-% to protect anonymity, and (optionally) switch to a more widely spaced
-% layout.
-% Mechanisms are also provided to allow the user to introduce text conditional
-% on the chosen submission mode.
-%
-% \section{Usage}
-%
-% To use this class, specify
-% \begin{verbatim} \documentclass{siggraph} \end{verbatim}
-% at the beginning of your document.
-% The following options may be included in the |\documentclass| command:
-%
-% \begin{mylist}
-%  \item \DescribeMacro{cameraready}|cameraready|,
-%	 \DescribeMacro{preprint}|preprint|,
-%	 \DescribeMacro{review}|review|, or
-%	 \DescribeMacro{widereview}|widereview|
-% \changes{v0.7.0}{1995/01/23}{Added widereview option}
-% \changes{v1.0.0}{1995/12/18}{Added preprint option}
-%	\newline These specify the submission mode for the paper.
-%	|cameraready|, the default, sets the layout parameters as
-%	described in section~\ref{layoutlist}.
-%	The |preprint| option adds page numbers and prints the message
-%	``To appear in the SIGGRAPH conference proceedings'' in the top
-%	margin.  This message can be changed with the
-%	\DescribeMacro{\preprinttext}|\preprinttext{|\meta{message}|}|
-%	command.
-%	The |review| option uses the same layout as |cameraready| but
-%	adds page numbers and modifies the title block as described
-%	in the next section.
-%	The |widereview| option is for people who prefer review papers
-%	that have a more widely spaced layout.
-%	It uses one-column mode with 12 point, double-spaced type.
-%	Other effects of these options will be described later.
-%
-%  \item \DescribeMacro{onecolumn}|onecolumn| or
-%	 \DescribeMacro{twocolumn}|twocolumn|
-% \changes{v0.6.3}{1995/01/09}{Fixed onecolumn option}
-%  \item \DescribeMacro{singlespace}|singlespace| or
-%	 \DescribeMacro{doublespace}|doublespace|
-% \changes{v0.8.3}{1995/03/27}{Added singlespace and doublespace options}
-%  \item \DescribeMacro{9pt}|9pt|,
-%	 \DescribeMacro{10pt}|10pt|,
-%	 \DescribeMacro{11pt}|11pt|, or
-%	 \DescribeMacro{12pt}|12pt|
-%	\newline These three sets of options will override the default
-%	settings for the number of columns, line spacing, and point size
-%	determined by the submission mode.
-%	Overriding the settings when in camera-ready mode, while allowed,
-%	is a violation of the submission specifications and will produce
-%	a warning message.
-%
-%  \item \DescribeMacro{version1996}|version1996| or
-%        \DescribeMacro{version1994}|version1994|
-%	\newline The submission specifications can change from year to
-%         year, and I will try to keep this class updated to match them.
-%         However, since many papers are painstakingly typeset to fit
-%         the allotted pages exactly, small changes in the format can
-%         radically change their appearance.  This class therefore includes
-%         a specification date to allow old documents to maintain their
-%         appearance even if the specs change.  Although the most recent
-%         version is always the default, I recommend including it in the
-%         options list anyways, so that you won't have to think about
-%         it several years down the road.
-%         (The only difference between the 94 and 96 versions is that
-%         the space for the copyright is now a half inch larger.)
-%
-%  \item Additionally, any other options supported by the |article| class
-%	may be used, except for |landscape| and |titlepage|, which are
-%	disabled.
-% \end{mylist}
-%	
-%
-% \section{Title Block, Abstract, and Cover Page}
-%
-% \subsection{Data fields}
-%
-% In addition to the |\title| and |\author| commands provided by the |article|
-% class, several other pieces of information can be set.
-% Each of these commands takes a single argument, the value to which the
-% corresponding field should be set.
-% \begin{mylist}
-%   \item \DescribeMacro{\affiliation}|\affiliation|
-%
-%       If all the authors share an affiliation, it can be set with this
-%       command rather than individually within the author command.
-%       The affiliation will appear centered below the author list.
-%
-%   \item \DescribeMacro{\category}|\category| and
-%	  \DescribeMacro{\format}|\format|
-% \changes{v1.1.0}{1996/01/08}{Replaced acmcategory/acmformat with
-%				category/format. Old versions still enabled.}
-%
-%	The paper category (research, systems, ...) and format (print, video).
-%
-%   \item \DescribeMacro{\contactname}|\contactname|,
-%	  \DescribeMacro{\contactaddress}|\contactaddress|,
-%	  \DescribeMacro{\contactphone}|\contactphone|,
-%	  \DescribeMacro{\contactfax}|\contactfax|,
-%	  \DescribeMacro{\contactemail}|\contactemail|
-%
-%	These should be used to set the information about the person to
-%	be contacted about the paper.
-%
-%   \item \DescribeMacro{\passport}|\passport|
-% \changes{v1.0.0}{1995/12/18}{Replaced acmpassport with passport.
-%				Old version still enabled.}
-% \changes{v1.1.0}{1996/01/08}{Disabled passport command; no longer required.}
-%
-%	The author who will receive compensation if the paper is accepted.
-%	\emph{As of 1996, this is no longer requested when submitting papers
-%	for review and the command has been disabled.}
-%
-%   \item \DescribeMacro{\keywords}|\keywords|
-% \changes{v1.1.0}{1996/01/08}{Added keywords command}
-%
-%	A list of keywords to be printed on the cover page
-%
-%   \item \DescribeMacro{\estpages}|\estpages|
-% \changes{v1.1.0}{1996/01/08}{Added estpages command}
-%
-%	The estimated number of pages that the paper would require in the
-%	conference proceedings.
-%
-% \end{mylist}
-%
-% \subsection{Title block}
-%
-% The title block is generated with the normal \LaTeX{}
-% \DescribeMacro{\maketitle}|\maketitle| command.
-% For a camera ready document it will contain:
-% \begin{mylist}
-%   \item Title
-%   \item Authors
-%   \item Affiliation (if any)
-% \changes{v0.6.2}{1995/01/05}{Fixed missing affiliation in title block}
-% \end{mylist}
-%
-% For a review paper it will instead contain:
-% \begin{mylist}
-%   \item Title
-%   \item Paper category
-% \end{mylist}
-% \changes{v1.1.0}{1996/01/08}{Removed paper format from first page of paper.}
-% The review options will also suppress printing of any information
-% specified with the |\thanks| command.
-%
-% \changes{v0.9.0}{1994/04/20}{Added teaser}
-% Some authors like to include a pretty picture of their results between
-% the title block and the start of the text to act as a teaser.
-% Because of the way \LaTeX's float placement scheme works, this seemingly
-% simple task is apparently impossible to do in a two column document
-% without making the picture part of the |\maketitle| command.
-% Therefore, that's exactly what I've done.
-% The class provides a \DescribeMacro{\teaser}|\teaser{|\meta{figure}|}|
-% command, whose contents will appear as a figure centered below the
-% title block.
-% Theoretically, anything that can appear in a |figure| environment can
-% appear here.
-% However, the current implementation is a bit of a kludge, so some things
-% might not work.
-% I've already been told that it isn't compatible with the |float| package.
-% I'll see what I can do to improve it when I get the chance.
-%
-% \changes{v0.9.0}{1994/04/20}{Added \cmd{\titlespace} and \cmd{\teaserspace}}
-% The space between the title block text and the rest of the document, and
-% between the teaser (if any) and the start of the main text are controlled
-% by the length parameters \DescribeMacro{\titlespace}|\titlespace| and
-% \DescribeMacro{\teaserspace}|\teaserspace|.
-% They both default to $\frac{1}{4}$ inch, but can be changed with the
-% normal \LaTeX{} length setting commands.
-%
-% \subsection{Abstract}
-%
-% The abstract should be specified with the |abstract| environment.
-% In addition to appearing in the paper itself, its contents will stored
-% and will appear on the cover page (in review mode).
-%
-% \subsection{Cover page}
-%
-% When the |review| or |widereview| option is specified,
-% a cover sheet will automatically be generated at the end of the document.
-% Placing the \DescribeMacro{\suppresscover}|\suppresscover| command
-% in the preamble will prevent this.
-% The cover sheet will contain:
-% \begin{mylist}
-%   \item Title
-%   \item Authors
-%   \item Affiliation (if any)
-%   \item Paper category
-%   \item Contact information
-%   \item A copy of the abstract
-%   \item List of keywords
-%   \item Estimated number of pages
-% \end{mylist}
-%
-% \subsection{Obsolete command}
-%
-% In previous versions of this class, it was necessary to use a command
-% called \DescribeMacro{\acmopening}|\acmopening| in place of the
-% |\maketitle| command and
-% \changes{v0.8.0}{1995/03/07}{Eliminated \cmd{\acmopening} command}
-% |abstract| environment in order to get the abstract to appear on the
-% cover page as well as in the text.
-% This is no longer necessary, and users should switch back to
-% the normal commands.
-%
-%
-% \section{Other Features}
-%
-% \subsection{Copyright notice}
-%
-% As with the old |siggraph.sty|, this class provides a 
-% \DescribeMacro{\copyrightspace}|\copyrightspace|
-% command to leave space at the bottom of the first column for the copyright
-% notice.
-% This command should be placed after the last footnote that will appear in
-% the first column.
-% As of yet, there is no way to have this done automatically, but I am looking
-% into it.
-%
-% \subsection{Title and section heading font}
-%
-% By default, this class uses bold sans-serif for the title and
-% section heading font.
-% This behavior can be altered with the
-% \DescribeMacro{\sectionfont}|\sectionfont{|\meta{fontcommands}|}| command.
-% \changes{v0.8.3}{1995/03/27}{Added \cmd{\sectionfont} command}
-% \meta{fontcommands} should be one or more font changing commands,
-% for instance ``|\rmfamily\scshape|'' or ``|\fontfamily{pcr}\selectfont|''.
-%
-% \subsection{Conditional text}
-%
-% \DescribeMacro{\ifcamera}\DescribeMacro{\ifreview}
-% \DescribeMacro{\ifcameraelse}\DescribeMacro{\ifreviewelse}
-% The class also provides the following four commands for writing text
-% conditional on whether camera-ready or review mode has been
-% chosen:
-% \begin{quote}
-%	|\ifcamera{|\meta{thenclause}|}|
-%
-%	|\ifreview{|\meta{thenclause}|}|
-%
-%	|\ifcameraelse{|\meta{thenclause}|}{|\meta{elseclause}|}|
-%
-%	|\ifreviewelse{|\meta{thenclause}|}{|\meta{elseclause}|}|
-% \end{quote}
-% The first two will generate the \meta{thenclause} if camera-ready
-% (resp. review) mode is chosen, otherwise they resolve to a null string.
-% The second two are the same as the first two but generate the
-% \meta{elseclause} instead of a null string if the condition is not met.
-%
-% These can be used for writing the paper so as to protect anonymity for
-% a submission for review, without having to worry about going back over it
-% months later to put the identifying information back in if the paper
-% is accepted.  For example:
-% \begin{quote}^^A
-%   |In \cite{FooBar1994}, \ifcameraelse{we}{Foo and Bar} showed that ...|
-% \end{quote}
-% or
-% \begin{quote}^^A
-%   |as illustrated in the following \ifcameraelse{three}{two} images:|
-%
-%   [include generic image]
-%
-%   |\ifcamera{| [include our logo] |}|
-%
-%   [include another generic image]
-% \end{quote}
-%
-% \subsection{Configuration file}
-%
-% Individual users or sites may wish to modify the behavior of this
-% class (for instance, to use a particular set of fonts.)
-% Rather than having people hack the |.cls| file, which can lead to
-% various incompatible versions at different sites, the class provides
-% for a configuration file.
-% After the class has finished loading, it will check to see if a
-% |siggraph.cfg| file exists in the \TeX{} search path.
-% If so, it will be input.
-% Any user-- or site--specific modifications should be placed in this file.
-% \textit{(See the copyright notice in the |siggraph.dtx| source file for
-% information on distribution of configuration files.)}
