44 | <para>This package has a test suite available which can perform a number of
|
---|
45 | checks to ensure it built correctly. However, the Expect test suite here in
|
---|
46 | Chapter 5 is known to experience failures under certain host conditions that
|
---|
47 | are not fully understood. Therefore, test suite failures here are not
|
---|
48 | surprising, but are not considered critical. Should you choose to run the test
|
---|
49 | suite, the following command will do so:</para>
