+    Starting in qpdf version 8.3.0, qpdf provides its own bash
+    completion support. You can enable bash completion with
+    <command>eval $(qpdf --completion-bash)</command>. If
+    <command>qpdf</command> is not in your path, you should invoke it
+    above with an absolute path. If you invoke it with a relative
+    path, it will warn you, and the completion won't work if you're in
+    a different directory.
