 ## Description :
-##    Configure /etc/hosts for a list of nodes.
+##    Generate ip-host binding list for a list of nodes, when internal DNS is missing.
 ##    1. Given a list of ip.
 ##    2. Get the ip-hostname list for each node by ssh
 ##    3. Update /etc/hosts for each node, thus every node to talk with others by hostname
 ## Sample:
-##    python ./bind_hosts_file.py --ip_list_file /tmp/bind_hosts --ssh_username root
+##    python ./generate_extra_hosts_file.py --ip_list_file /tmp/bind_hosts --ssh_username root
 ##                \ --ssh_port 22 --ssh_key_file ~/.ssh/id_rsa
 ## Requirements:
 ##     1. pip install paramiko
