Meh just ok for POC. Take the time to build a proper cli which tells you all the parameters and args it would take.
$ ./example.py
Type: Example
String form: <__main__.Example object at 0x10674d890>
File: ~/tmp/example.py
Usage: ./example.py
./example.py hello
$ ./example.py hello
Hello world!
$ ./example.py hello adsf
Hello adsf!
