% This demo file shows how to randomize the choices of a quiz created
% by the exerquiz package, where the choices have verbatim text.
%
% The questions themselves are not randomized, but they can be, see random_tst.tex
% to see how to do this.

% When using cross-referencing and \useLastAsSeed, the cross-references are never up to date.
% Once you randomize, read the auxiliary file (\jobname_rt.save), copy the first seed listed
% and paste in as the argument of \useThisSeed. Compile a few more times to bring cross-refereces
% up to date.
