Running this test suite
-----------------------

 * follow any needed steps for test fixture set up; see FIXTURE.txt

 * run using a simple

   ./run.sh


Writing a test
--------------

 * Create a new test directory following the established naming pattern.

   * do not name the directory starting with a "_"

 * Add a script file called run.sh into that directory.

   * Invoke whatever you want from that file to run the test.

   * use "exit 1" to indicate a test FAILURE

   * use "exit 2" to indicate a test NO RESULT (when a missing precondition
     means its not possible to run the test)

   * use "exit 0" to indicate a test SUCCESS

 * the main run.sh will pick up the new test automatically.
