% Some conferences (e.g. NIPS and UAI) state in their style guides that the
% references heading should be a subsubsection-level heading --- but using their
% style file with bibtex usually ends up with a section-level heading. This hack
% fixes that.
% 
% If you pass the small option then it \small's the references, which is
% explicitly allowed by at least NIPS.
% 
% If you pass the tight option then the package scrunches space between the
% references too. The allowability of this is somewhat more dubious.
% 
% Include this *after* natbib or any other packages that might over-ride this
% stuff. Using one of:
% 	\usepackage{bibhacks}
% 	\usepackage[small]{bibhacks}
% 	\usepackage[small,tight]{bibhacks}
