\NeedsTeXFormat{LaTeX2e}[1995/12/01]
\ProvidesClass{sigplan-proc}
[2002/06/21 v1.4
Document Class]
% This file has a long and troubled history:
% The original (LaTeX 2.09) document style for this purpose was by
% Olin Shivers (1991).
% Ken Traub and Kevin Theobald added some new features in 1993.
% Back then, it was called acmconf.sty.
% Mike Sperber converted it to an LaTeX2e document class called
% acmconf.cls in 1994.
% From 1999 on, G.K.M. Tobin and Gerry Murray took Traub's style,
% and modified it extensively.
% This version was called acm_proc_article-sp.cls, V2.01SP
% In 2002, Mike Sperber <sperber@informatik.uni-tuebingen.de>
% wrote this file, intended to be compatible with
% acm_proc_article-sp.cls V2.01SP, but with layout parameters
% matching ACM's guidelines at
% http://www.acm.org/sig_volunteer_info/conference_manual/6-5PROC.HTM
% It contains code from all previous versions, but is much shortened
% to avoid redundancies with the standard LaTeX2e styles.
% Here are the main changes to acm_proc_article-sp.cls, as far as the
% interface is concerned:
% It doesn't load any of the utility packages, specifically, it
% doesn't load epsfig, amssymb, amsmath, and amsfont.
% It depends on David Carlisle's pslatex package, found on any CTAN
% host, say at
% ftp://ftp.dante.de/tex-archive/macros/latex/contrib/supported/pslatex/
% There's once again a preprint document-class option. (Just like in
% Olin's original style file.) Unlike Olin's style, it has no
% influence whether the \toappear information is printed. It only
% switches off explicitly doing \pagestyle{empty}, allowing you to
% have page numbers, for example.
% There's also a nocopyrightspace document-class option which prevents
% the reservation of space at the bottom left of the title page for
% the copyright notice.
% It conforms to LaTeX2e's NFSS2, so there aren't any silly
% font-changing commands specific to section headers, like \secit{}
% etc.
