Headers pushed to PDF doc properties

[Javier Ruiz-Alma]

Some (but not all) entries from the \header block are pushed as PDF properties, and either appear in the "Description", or in the "Custom" fields tab of the PDF document "Properties" dialog box:

• title
• composer (shown in the "Author" field, as well as in a custom "Composer" field).
• keywords
• arranger (custom)
• subtitle (custom)
• poet (custom)
• copyright (custom)

Is there a way to add an arbitrary header field and have LilyPond add it to the list of 'custom' properties for the PDF?

 

 

Thx, Javier
