[Scribus] Setting up PDF for newspaper press

[Frank Cox]

Is there a way to generate a PDF file from Scribus with a very specific layout.

I need each PDF page consist of four "actual" pages, to look something
like this:

1   4
2   3

with pages 1 and 4 being "upside down" to pages 2 and 3.  (These
aren't the right page numbers and I don't have the template in front
of me at the moment, but that's the general idea.)
