+# CONTACTS.CFG - SAMPLE CONTACT/CONTACTGROUP DEFINITIONS
+#
+#
+# NOTES: This config file provides you with some example contact and contact
+#        group definitions that you can reference in host and service
+#        definitions.
+#
+#        You don't need to keep these definitions in a separate file from your
+#        other object definitions.  This has been done just to make things
+#        easier to understand.
