Can I remove the page breaks (or re-flow postscript documents) in PDF files?
Alternatively, if there's a program that can convert a PostScript file into a single-page PDF by calculating the necessary page size, that would work for me too.


Any PostScript to PDF converter would convert a valid one-page postscript file into a one-page PDF file. You can for example use OS X’s own pstopdf or Ghostscript’s ps2pdf script. If you need to tighten the bounding box, pdfcrop will do the trick.
