All of the project's documentations used etcdctl put command for examples like this https://github.com/coreos/etcd/blob/master/etcdctl/README.md. But when I used, I got an error. No help topic for 'put'. I can use set command correctly.

I want to know if the document is out of sync or I'm wrong ?

I found etcdctl/ctlv2 has set_command.go and etcdctl/ctlv3 has put_command.go in source code.
