[2022/09/13 v0.4 hyperref PDF/A and PDF/X conformance]
% Usage: Load hyperpdfx before hyperref. If you load hyperref first, enable
% the pdfa and pdfusetitle options.
%
% You will need to populate metadata fields, at least \title{} and \author{}
% or alternatively \hypersetup{pdfauthor={},pdftitle={}}
%
% Use the cmyk option to attempt PDF/X conformance
%
% See package Readme.md for more info
