More PDF metadata

[Henning Hraban Ramm]

Is it possible to insert PDF metadata (pdfmarks) into LilyPond's  
PostScript output?

I'd like to use existing LilyPond header information to fill the PDF  
header, say

[       /Title (header:title)
        /Author (header:poet / header:composer)
        /Subject (perhaps header:instrument, header:lastupdated)
        /Keywords (from other fields, e.g. Mutopia's header:maintainerWeb)
/DOCINFO pdfmark

Further it would be good to put structural information as bookmarks  
into the PDF, esp. for bigger works.

I'd suggest to include that into LilyPond proper, otherwise I'd like  
to know how I can do it.
I guess I could write an EPS containing the PostScript commands and  
include that, but LilyPond should be able to do it somehow internally...

The same already was asked in 2007:

(Seems the poster got no answer.)

There also was a thread on adding pdfmarks for each bar number:

(Seems nothing came out of that?)
