I have put a new version of my -markup package in http://www.oxytropis.plus.com/groff
I have added support for eqn, and included the documentation preformatted as pdf. The main features missing are now footnotes and bibliographies. I have added equations because I am still worried about the mystery dimension adjustments for the Standard Fonts. Are they still now required? I tried removing them when installing the URW clones, and frankly I could not see any difference. Does anyone know about this? Denis
