[Groff] pdfmark - section numbers

[Scott Moore]

I am wondering if it is possible to
create a pdf bookmark which does not
contain a section numbered entry ?

Page references are okay, I just do
not need section heading numbers.

Am I correct to say that the example provided
takes the .NH and passes the section level
through to the pdfmark macro ?

Is the pdfmark.tmac dependent on the ms macro
package ?  Is there a way to turn off section
numbering in the table of contents ?  I do not
need it in my document, nor do I require it in
TOC.

Also, has anyone put together a more
detailed / complete reference manual than
that provided with groff for pdfmark ?
The last few chapters seem to be as yet
incomplete.

Thanks
Scott
