Swap landscape of postscript document

[Coen De Roover <cderoove@vub.ac.be>]

Hi,

I have several postscript documents that, when opened with gv, are upside
down until I select the swap landscape option in the menu.
However, when I try to print multiple pages on one sheet (using the psnup
-2 command from psutils), the pages are printed in the wrong order (higher
page numbers are at top of sheet).

Is there a way to swap landscape on the command line ?
(or is there an option of the psnup command to do just that ?)

(The files I'm trying to print are
http://www.cs.berkeley.edu/~russell/slides/chapter03.ps.gz
and
http://tinf2.vub.ac.be/cpp/transparencies.ps)

Thanks in advance,
Coen De Roover
