+// Package networks contains functionality for working with Neutron network
+// resources. A network is an isolated virtual layer-2 broadcast domain that is
+// typically reserved for the tenant who created it (unless you configure the
+// network to be shared). Tenants can create multiple networks until the
+// thresholds per-tenant quota is reached.
+//
+// In the v2.0 Networking API, the network is the main entity. Ports and subnets
+// are always associated with a network.
