How to add page numbers to Postscript/PDF

Question

If you\'ve got a large document (500 pages+) in Postscript and want to add page numbers, does anyone know how to do this?

Answer 1

Oh, it's a long time since I used postscript, but a quick dip into the blue book will tell you :) www-cdf.fnal.gov/offline/PostScript/BLUEBOOK.PDF

On the other hand, Adobe Acrobat and a bit of javascript would also do wonders ;)

Alternatively, I did find this: http://www.ghostscript.com/pipermail/gs-devel/2005-May/006956.html, which seems to fit the bill (I didn't try it)
