%% ---------------------------------------------------------------------------
%% This version of arcs.sty was hacked up to work around an incompatibility
%% between arcs and relsize. See Michael Sharpe's August 2013 posting to
%% the XeTeX list (
http://tug.org/pipermail/xetex/2013-August/024674.html)
%% for details, but the patch is basically to replace \@gobbletwo with a
%% newly defined \@gobblethree.
