+ [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
