===============================================================
Some of the tests may take up to a couple of minutes to run.
Please be patient.

If you see that a test failed, please run it as follows:
   perl -w ta/failed_test_name.pl

That will show you details about failure. Send the output to
tech@xao.com along with your perl version and short description
of what you think might be the reason.
