Modify Existing PDF to Add Page N of NNN Footer

Question

How can I use pdftkeither from the command line (or preferably from Ruby) to add page numbers to the bottom of a pre-existing PDF?

I am looking for this format:

• Page 1 of 2

• Page 2 of 2

If you want to do this using pdftk, you can do this using either an operation multistampor multibackground. But first, you have to prepare a document (with software of your choice) that creates footers Page X of Yon blank pages (in PDF format).
