%%% This is onecw.sty, version of 29 june 1990, by Nico Verwer.
%%% Normally, LaTeX issues a warning every time it encounters an
%%% undefined citation. Thus you will get multiple warnings for the same
%%% citation. When you include this sty file, only one warning will be
%%% issued for every citation.
%%% Almost all of this code is directly taken from latex.tex.
%%% Please email suggestions (I'm still looking for a better name),
%%% comments, etc. to verwer@cs.ruu.nl .
