+# This test confirms that CORBA::is_nil works
+
+TAO implements `CORBA::is_nil` as a function template, which merely
+checks the argument for zero. The template is specialized for
+`CORBA::Object_ptr`, and this specialization additionally checks
+whether a non-NULL argument might be an unevaluated nil object
+reference.
+
+Because template specialization is used and not an ordinary overloaded
+function, the specialized variant is *not* called for pointers to
+derived classes. This will work only if TAO ensures that all nil
+object references that have been narrowed to a derived class are
+converted to null pointers, i.e., to ensure that the generic template
+produces the correct result.
+
+This test has the server return a nil object reference and the client
+uses lazy resource usage, to confirm that CORBA::is_nil correctly
+identifies the nil object reference. See issue #1203, which pointed
+out that only CORBA::Object_ptr has a template specialization for
+CORBA::is_nil, but not derived interfaces.

+# TAO GIOP Fragmentation Bug
+## Reproduces a bug when GIOP fragmentation is used 
+
+The server returns a string sequence with two elements, the first is a
+long 4kB string with repeating character 'A', the second element is
+the string "Hello World". If one removes the command line parameters
+`-ORBMaxMessageSize 1024` from `run_test.pl` everything
+works as expected, but with these settings, which cause GIOP
+fragmentation, the client receives an empty string as the second
+element of the sequence.

+portspan Test
+-------------
+
+The portspan test verifies that the portspan option to the ORB_init() call
+behaves correctly. This option allows you to restrict the port that a
+server-side ORB will use to listen for requests, from a given range of port
+numbers, starting at a given initial port.
+
+The test works by starting a simple ORB on an endpoint with a portspan of 2.
+server -ORBEndpoint iiop://:5555/portspan=2. The test script does this
+three times and reports an error if the first two don't succeed or if the
+third call doesn't fail.
+
+The test accepts the following mutually-exclusive protocol arguments to
+determine which protocol gets tested for portspan support. You must supply
+exactly one of these arguments:
+
+• -iiop
+• -diop
