% This is PUBREF.STY Version 1.2 as of 20 June 2001
%    by Brian Gerkey (gerkey@usc.edu)
%
% Inserts postcript to place a publication reference at the top of a
% document.  The (default) result looks something like:
%
%     In Proceedings of the Intl. Conf. on Unsustainable Living
%        pages 1-4, Los Angeles, California, May 15-16, 2001
%
% (the string "Proceedings of..." will be in italics)
%
% NOTE: These lines will NOT appear in your DVI viewer.  They will only
%       appear in the resultant postscript after you run dvips.
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% To use this package:
%
% Put this line near the top of your file
%
%    \usepackage[<options>]{pubref}
%
% Then call \pubref somewhere in your preamble (i.e. BEFORE \begin{document}):
%
%    \pubref{<booktitle>}{<address>}
%
% For example:
%
%    \pubref{Proceedings of the Intl. Conf. on Unsustainable Living}
%           {pages 1-4, Los Angeles, California, May 15-16, 2001}
%
% You can leave the <address> field empty; e.g:
%
%    \pubref{Proceedings of the Intl. Conf. on Unsustainable Living}{}
%
%
% Options are follows (some are logically exclusive):
%
%    in        - Print the string "In" before the <booktitle> (default)
%
%    submit    - Print the string "Submitted to" before the <booktitle>
%
%    toappear  - Print the string "To appear in" before the <booktitle>
%
%    noprefix  - Don't print any prefix string before the <booktitle>
%
%    firstpage - Print the reference only on the first page (default)
%
%    everypage - Print the reference on every page
%
