If I want something (e.g., a logo) to appear on each page of a document
then I could either write the code once for each page, or write a
procedure (which goes into the document's prolog) which does the
necessary and then invoke this procedure for every page. One benefit of
this latter solution is a reduction in the size of the PS file.

But what if the thing I want to appear on each page is an EPS file? Is
it legal to have code like the following:

	/foo
	{
		"some housekeeping before including EPS file"
		... included EPS file here
		"some housekeeping after including EPS file"
	} def

and then invoke foo multiple times in the document? I looked in the Red
Book (the new one for PS Level 2) at the sections which deal with EPS
files and couldn't find any discussion of this.

What I think would prevent the above from working is if the EPS file
contained an image whose data was read directly from "currentfile" (as
is often the case with images).

Comments, anyone?
