I want to operate on a saved PostScript listing using UNIX tools,
with the aim of producing a new file that will print multiple
copies of each page without re-imaging the page for each copy.

We have a utility called "ditorder" that is supposed to do this
(part of the Elan "eroff" package) but it barfs on PostScript files
produced by Frame 2.0d on the NeXT.  We have the Transcript package
from Adobe (it is distributed with the NeXT software package) but
it doesn't seem to contain a utility to do this.  All it has is
"psrev" which will select pages but not print them in multiples.

Attached below find a fragment from the end of one page and the
start of the next.  Surely there is some simple thing I can do
in this area of a .ps file so that the just-imaged page will
display <n> times without having to be re-drawn entirely! Like,
just repeat the "showpage" line <n> times?

Thanks for any help.
