Dear list users,
How can one go about implementing a ruler around the page/text area (such
as a background) like the one provided by the latex package fgruler?
https://www.ctan.org/tex-archive/macros/latex/contrib/fgruler or koma
script's \layercontentsmeasure?

Hans,
Thanks a lot. I'm still trying to apply this to the top/bottom; I suppose
it should be simple after I have a firmer grasp of language.
