hyperref-autonameref.tex

% LaTeX kernel provides
%    \ref and \pageref,
% hyperref (with nameref) adds
%    \autoref,      which acts like "<ref name>~\ref"
%    \autonameref,  which acts like "page~\pageref"
% and
%    \nameref,      which prints the sectioning title.
% This tiny tex file adds
%    \autonameref,  which acts like "<ref name>~\nameref"
% (originally developped for https://github.com/pgf-tikz/pgfplots/issues/367)
