# Poor man's qingcloud single instance management script. You may find this script useful, if you:
# - are an individual qingcloud user. do not have a lot of instances (assuming only one)
# - do not need to run instance 7x24. instances are powered off most of the time
# - do not use advanced networks. no routers, no private networks. just an instance with default network and an eip attached
# - want to save money
# - use ssh to login, have following lines in ~/.ssh/config:

- sftp is configured easier to use than ssh (rsync or git)

This script is very simple and does not handle complex cases. Use rsync to:
- set up an initial mirror
