Summary description:  Embed XMP metadata within a LaTeX document

Announcement text:
 XMP (eXtensible Metadata Platform) is a mechanism proposed by Adobe
 for embedding document metadata within the document itself.
 The metadata are designed to be easy to extract, even by programs
 that are oblivious to the document's file format.
 Most of Adobe's applications store XMP metadata when saving files.
 Now, with the hyperxmp package, it is trivial for LaTeX document
 authors to store XMP metadata in their documents as well.

 hyperxmp integrates seamlessly with hyperref and requires virtually
 no modifications to documents that already exploit hyperref's mechanisms
 for specifying PDF metadata.  hyperxmp can embed a wide variety of metadata
 as XMP, including the list of authors, document title, contact information
 (telephone number, postal address, email address, etc.), copyright statement,
 keywords, natural language, and much more.  hyperxmp is compatible with
 pdflatex, lualatex, xelatex, latex+dvipdfm, and latex+dvips+Distiller.

 Version 5.8 includes a new add_byteCount Perl script that postprocesses
 a PDF file to specify the true file size in the XMP packet
 (property: <prism:byteCount>).
 The documentation describes how to configure the latexmk build tool
 to invoke add_byteCount automatically.
 Thanks to John Collins for both the script and the configuration code.
