%%% This file contains kludges and hacks to enable the bespoke
%%% cross-referencing system found in cms-notes-intro.pdf and
%%% cms-dates-intro.pdf.  It contains code adapted from several
%%% sources, especially from Ulrich Dirr's hyperendnotes.sty, found on
%%% comp.text.tex.  Please don't load it unless you really mean to, as
%%% it messes with the standard biblatex-chicago macros.

%%% These counters are for the slightly more informative endnote marks
%%% used in the notes intro.
