[O] How to reuse page keywords for LaTeX with pdfkeywords and hyperref package?

[Mikhail Titov]

Hello all!

I would like to be able to have same keywords for both HTML and PDF output. I 
was a bit surprised that it is not there yet. I’m not a lisp user:( Could 
someone suggest what needs to be done to use org-export-page-keywords to set 
the value of pdfkeywords option of hyperref LaTeX package?
