+/*  This piece of PostScript code (initial idea 2001 by Michael
+    Allerhand (michael.allerhand at ed dot ac dot uk, vastly
+    improved by Till Kamppeter in 2002) lets Ghostscript output
+    the page accounting information which CUPS needs on standard
+    error.
+    Redesign by Helge Blischke (2004-11-17):
+    - As the PostScript job itself may define BeginPage and/or EndPage
+    procedures, or the alternate pstops filter may have inserted
+    such procedures, we make sure that the accounting routine
+    will safely coexist with those. To achieve this, we force
+    - the accountint stuff to be inserted at the very end of the
+        PostScript job's setup section,
+    - the accounting stuff just using the return value of the
+        existing EndPage procedure, if any (and providing a default one
+        if not).
+    - As PostScript jobs may contain calls to setpagedevice "between"
+    pages, e.g. to change media type, do in-job stapling, etc.,
+    we cannot rely on the "showpage count since last pagedevice
+    activation" but instead count the physical pages by ourselves
+    (in a global dictionary).
