-### NOTE
-### it is far easier to extend the 'delete' method on the client side,
-### to know when the client is deleted, rather than listening to server
-### to get notified. However, 'generate_cli.py' cannot add extra stuff
-### in the generated client module. So, here a class with the same name
-### is created, and client module is patched.
