      '' GNU Shishi is an implementation of the Kerberos 5 network
	 authentication system, as specified in RFC 4120.  Shishi can be
	 used to authenticate users in distributed systems.

	 Shishi contains a library (`libshishi') that can be used by
	 application developers to add support for Kerberos 5.  Shishi
	 contains a command line utility (1shishi') that is used by
	 users to acquire and manage tickets (and more).  The server
	 side, a Key Distribution Center, is implemented by `shishid'.
