It depends entirely on whether the file you are working with is an
Encapsulated PostScript file with the appropriate %%Page comments.  If
so, it is a fairly simple matter to filter out the pages you don't want
by looking at the comments.  On the other hand, there are PostScript
programs that are unencapsulatable (?).  Consider the following
fragment:
      /tmpstr 10 string def
      /Times-Roman findfont 300 scalefont setfont
      0 1 9 {tmpstr cvs 100 100 moveto show showpage} for

The last line produces 9 pages of output, so to only output pages 4-6
you would actually have to modify the program.
