% VLDB DOCUMENT STYLE

%
% SIG-ALTERNATE DOCUMENT STYLE
% G.K.M. Tobin August-October 1999
% adapted from ARTICLE document style by Ken Traub, Olin Shivers
% also using elements of esub2acm.cls
% HEAVILY MODIFIED, SUBSEQUENTLY, BY GERRY MURRAY 2000
% ARTICLE DOCUMENT STYLE -- Released 16 March 1988
% for LaTeX version 2.09
% Copyright (C) 1988 by Leslie Lamport
%
%
%%% sig-alternate.cls is an 'ALTERNATE' document style for producing
%%% two-column camera-ready pages for ACM conferences.
%%% THIS FILE DOES NOT STRICTLY ADHERE TO THE SIGS (BOARD-ENDORSED)
%%% PROCEEDINGS STYLE. It has been designed to produce a 'tighter'
%%% paper in response to concerns over page budgets.
%%% 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 =3D 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.
%%% 5) US letter paper size (since v1.8c)
%%%
%%%
%%% 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*'.
%%%
%
%%% Copyright Space:
%%% This style automatically reserves 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.
%%%
%%% WARNING:
%%% Some dvi-ps converters heuristically allow chars to drift from their
%%% true positions a few pixels. This may be noticeable with the 9pt sans-serif
%%% bold font used for section headers.
%%% You may turn this hackery off via the -e option:
%%% dvips -e 0 foo.dvi >foo.ps
