"""Node Example

To use this example run it interactively through the Python interactive
shell using the -i option as per the shebang line above.

i.e: python -i hello_node.py host port

At the python prompt:

    >>> x = app.fire(hello())
    >>> <Hello[*.hello] ( )>

    >>> x
    <Value ('Hello World! (16030)') result=True; errors=False; for <Hello[*.hello] ( )>
    >>> y = app.fire(remote(hello(), "test"))
    .
    .
    .
    >>> y
    <Value (u'Hello World! (16035)') result=True; errors=False; for <Remote[*.remote] (<Hello[.hello] ( )>, 'app2' channel=None)>
