+#          Test of --checkpoint option. This does not validate the 
+#           checkpoint file itself.
+#
+# Output:  "TEST: #.#" followed by "SUCCESS" if test was successful, OR
+#          "FAILURE: ..." otherwise with an explanation of the failure, OR
+#          anything else indicates a failure mode that must be investigated.
