How to merge two postscript files together?

Question

I am trying to merge two or more postscript files into one. I tried concatenation but it does not work as each postscript file may have different resource header.

FYI I've found that this does not work right in one case - if any file but the first file has links in it, they will not be correct in the final merged PDF. In particular, if say the second PDF has a link to its second page, it will end up being a link to the second page of the merged document, which is not right...

Note that pdftk (which can be downloaded free) will get the links right.
