```
$ etcdctl set /message Rob
Rob
$ curl -L http://127.0.0.1:4001/v2/keys/message
{"action":"get","node":{"key":"/message","value":"Rob","modifiedIndex":20,"createdIndex":20}}core@localhost ~ $ $ etcdctl set /message Rob2
Rob2
$ curl -L http://127.0.0.1:4001/v2/keys/message
{"action":"get","node":{"key":"/message","value":"Rob2","modifiedIndex":21,"createdIndex":21}}
$ ./etcd-v0.3.0-linux-amd64/etcd --version
