Some PostScript printers place their output face-down in the collector
bin, and some place it face-up.  Some producers of PostScript
documents arrange "page 1" at the beginning of the file, and some put
it at the end.  The selection is really pretty arbitrary, because
there's no way to know what sort of printer (face-up or face-down) the
recipient will have.  So it's often decided by what sort of printer
the author uses.  About half the time, this leads to wasting the
recipient's secretary's time recollating the document.  It's
mind-numbingly dull work and they have better things to do.

Adobe's TranScript package includes a program called "psrev" that can
take any format-conformant PostScript document and (re-)reverse it, or
even select page ranges for printing.  I've looked through the sources
of psroff, psf, a2ps, and groff and found nothing that looks
promising.  It's probably a quick hack (likely a Perl one-liner :-)
and one of those wheels that shouldn't be reinvented.

Has anyone written a freely available PostScript page reverser?
