+    d) Performance Statistics
+    -------------------------
+    This utility can collect database performance information from either the AWR/ASH views, or from STATSPACK.
+    Use of the AWR/ASH views requires that you have a license from Oracle for the Diagnostics Pack.
+    Note that the AWR/ASH tables and views are installed and enabled by default on Enterprise versions of Oracle,
+    so their existance is not necessarily indicative of a license.  
+    If you are unsure of your license status, use STATSPACK for performance data collection.
