%
% ``acmsiggraph'' LaTeX class.
% - borrows *heavily* from Daniel Kartch's 'siggraph' class. 
% - also uses pieces of 'apalike.sty' and 'authordate1-4.cls'
% - modifications include adjustment of citation format to more closely
%   align with new (for SIGGRAPH 2002 conference and beyond) reference
%   and citation formatting requirements.
% - version 0.1 2001/06/01 Stephen Spencer (spencer@acm.org)
% - version 0.2 2001/10/15 Stephen Spencer
%   - the "\onlineid" variable works with the "review" mode, placing a
%     banner across the top of each page "Online Submission ID 'onlineid'
% - version 0.3 2002/01/11 Stephen Spencer
%   - disabled the cover page option.
% - version 0.4 2002/01/23 Stephen Spencer
%   - based on suggestions from James O'Brien, the following changes:
%     - correction if '\ifcamera' and '\ifcameraelse' commands
%     - page numbering in both review and preprint modes
%     have been made.
% - version 0.5 2005/01/22 Stephen Spencer
%   - removed the category markers
% - version 0.6 2006/12/15 Stephen Spencer
%   - tightened up space around section headings
% - version 0.7 2007/04/05 Stephen Spencer
