+%description
+This library provides a number of PDF::Reader[0] based tools for use in
+testing PDF output.  Presently, the primary purpose of this tool is to
+support the tests found in Prawn[1], a pure Ruby PDF generation library.
+However, it may be useful to others, so we have made it available as
+a gem in its own right.
