+	  Kerberos is a system for authenticating users and services
+	  on a network. Kerberos is a trusted third-party service.
+	  That means that there is a third party (the Kerberos server)
+	  that is trusted by all the entities on the network (users
+	  and services, usually called "principals"). This is the MIT
+	  reference implementation of Kerberos V5.
