* Description: This program tests the OWSTL test fixtures. This is to check
*              that the code used to conduct the other tests is working. The
*              strange name for this file ensures that it will appear first
*              in the test sequence (according to our usual convention of
*              ordering tests alphabetically). If this test fails, any later
*              failures have a good chance of being spurious.
