+// Package naming provides an etcd-backed gRPC resolver for discovering gRPC services.
+//
+// To use, first import the packages:
+//
+// import (
+// "github.com/coreos/etcd/clientv3"
+// etcdnaming "github.com/coreos/etcd/clientv3/naming"
+//
+// "google.golang.org/grpc"
+// "google.golang.org/grpc/naming"
+// )
+//
+// First, register new endpoint addresses for a service:
+//
+// func etcdAdd(c *clientv3.Client, service, addr string) error {
+// r := &etcdnaming.GRPCResolver{Client: c}
+// return r.Update(c.Ctx(), service, naming.Update{Op: naming.Add, Addr: addr})
+// }
+//
+// Dial an RPC service using the etcd gRPC resolver and a gRPC Balancer:
+//
+// func etcdDial(c *clientv3.Client, service string) (*grpc.ClientConn, error) {
+// r := &etcdnaming.GRPCResolver{Client: c}
+// b := grpc.RoundRobin(r)
+// return grpc.Dial(service, grpc.WithBalancer(b))
+// }
+//
+// Optionally, force delete an endpoint:
+//
+// func etcdDelete(c *clientv3, service, addr string) error {
+// r := &etcdnaming.GRPCResolver{Client: c}
+// return r.Update(c.Ctx(), "my-service", naming.Update{Op: naming.Delete, Addr: "1.2.3.4"})
+// }
+//
+// Or register an expiring endpoint with a lease:
+//
+// func etcdLeaseAdd(c *clientv3.Client, lid clientv3.LeaseID, service, addr string) error {
+// r := &etcdnaming.GRPCResolver{Client: c}
+// return r.Update(c.Ctx(), service, naming.Update{Op: naming.Add, Addr: addr}, clientv3.WithLease(lid))
+// }
+//
