% (Partially based on CITESIDX.STY by Frank Buchholz)
% (Contributions by Florian Werner Sauer)
% (Modifications by Bjoern Briel)
%
% Main purpose:
% 	Add reference-page-list to bibliography-items.
%
% Features:
%	- This is done WITHOUT using the index-facility.
% 	- Full transparency - no special \cite-replacement
% 	- Works with or without BibTeX
% 	- No extra LaTeX runs needed, neither external programs
% 	- Customizeable look of the back-references
%
% Caveats:
% 	- Does probably NOT work with other \cite-related style-options
% 	  which redefine the (internal) \@citex macro
%	- Citation tags may no longer contain a '=' char due to expansion
%	  issues.
%
% Usage:
% 	\usepackage{citeref}
% 	No Options declared
%
% 	Change Style of printed page references by redefining the macro
% 	'\bibitempages#1'. The parameter is a comma-separated list of 
% 	page references. The default macro puts it into brackets [...].
%
% 	Print comments in the bibliography: Use the macro
%	\bibintro{Blah...} before \thebibliography
%
% Revision History:
%	1999/01/05	Initial release
%	1999/27/05	Got sometimes wrong page numbers;
%	                Removed \immediate from \write of \citepageref-Macro
%	                in redefinition of \@citex to fix this
