+% pdfread.ps - A procset for interpreting an ordered PDF 1.3 file.
+
+% This module defines routines for interpreting a PDF file with
+% a Postscript interpreter. To convert a PDF file into Postscript
+% just pre-contcatenate this file. The PDF file must satisfy
+% few constraints :
+%
+% 1. It must contain only Postscript level 2 objects encoded with
+% the PDF 1.3 language. Higher PDF levels must be re-distilled
+% with CompatibilityLevel=1.3 .
+%
+% 2. Objects must be ordered so that any resource be defined before
+% its usage.
+%
+% 3. The PDF file must not include other PDF files.
+% Consequently we have a single instance of the PDF reader.
+% We use this fact to simplify binding of the routines.
+%
+% 4. The PDF root object must always have the object id 1.
+%
+% 5. Generations besides 0 are not allowed.
+%
+% 6. xref must appear after all objects.
+%
+% Assuming the currentfile isn't positionable.
+% As a consequence, the reader fully ignores xref.
