I am working on a book that will have a section referencing page numbers and page lines, for example: see p. 27, line 35. My staff and I are comfortable using page cross references for this sort of task, but we've never had a reason to reference page lines. Would this script be able to work in conjunction with something like that? I am otherwise stumped.
Please note that if we were to use the line number script, the lines would either have to be in the slug or on a non-printing layer (neither of which do I have much experience with).
