+** File:        lazyinit.c
+** Description: Testing lazy initialization
+**
+**      Since you only get to initialize once, you have to rerun the test
+**      for each test case. The test cases are numbered. If you want to
+**      add more tests, take the next number and add it to the switch
+**      statement.
+**
+**      This test is problematic on systems that don't support the notion
+**      of console output. The workarounds to emulate that feature include
+**      initializations themselves, which defeats the purpose here.
