+# Purpose: Test of SLURM functionality
+#          Test if we can trick SLURM into using the wrong user ID
+#          through an LD_PRELOAD option.
+#
+# 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.
