Hi Pierre, What I meant was that PDF features like hyperlinks and navigation menus can be achieved using a standard PostScript interpreter—you don't need a dedicated *roff-to-PDF converter if your Troff of choice already supports high-quality PostScript output.
Moreover, the PostScript code I gave was purely illustrative. If you're interested in learning more about the syntax, the definitive reference is here: https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/pdfmark_reference.pdf#G7.1500796 (Note that I've linked you directly to the relevant section using the feature in question).
