As a side issue, it looks like the .pdfinfo macro mentioned in this thread is un(der)documented.
It's documented in the pdfmark documentation (contrib/pdfmark/pdfmark.ms), but it seems to apply to any document rendered with groff's -Tpdf option, not just ones using the pdfmark package, as the macro itself is defined in pdf.tmac. Comments in this tmac file give a usage statement and examples for .pdfinfo, but this is not where users are likeliest to find it. It isn't documented in the current gropdf man page, which is where I'd first think to look. This man page documents a number of PDF-specific commands recognized by the \X escape, but no macros, although pdf.tmac defines several that appear intended to be user-facing. Am I overlooking something, or is this a documentation shortfall?
