-    If Adobe Reader is installed as <command>acroread</command>, some

-    verify that Adobe Reader can open the files that qpdf creates.
-    They require version 8.0 or newer to pass.  However, in order to
-    avoid having qpdf depend on non-free (as in liberty) software, the
-    test suite will still pass without Adobe reader, and the test
