+Package nodes provides information and interaction with the Virtual IP API
+resource for the Rackspace Cloud Load Balancer service.
+
+A virtual IP (VIP) makes a load balancer accessible by clients. The load
+balancing service supports either a public VIP, routable on the public Internet,
+or a ServiceNet address, routable only within the region in which the load
+balancer resides.
+
+All load balancers must have at least one virtual IP associated with them at
+all times.
