You can call it anything you want but if you want the standard tools for
constructing tokens to work with your cell, you will call it

	afs/cellname@REALM

as in

	afs/athena.mit.edu@ATHENA.MIT.EDU

or

	afs/secure-endpoints.com@WINDOWS.SECURE-ENDPOINTS.COM

or

	afs/this.is.my.cell@THIS.IS.YOUR.REALM.COM
