 Getting Started
 ===============
 This code will create a server that logs all requests, and provides two methods to clients:
 add and subtract:
 
 .. literalinclude:: ../../jsonrpc/example_server.py
    :language: python
    :linenos:
    :tab-width: 2
    :lines: 2,3,34-
 

 To use this server (which is included as jsonrpc.example_server), start it and the client in this way:

 .. code-block:: console

    % python -m jsonrpc.example_server &

    % python -i -m jsonrpc.__main__ http://localhost:8007

    
 .. code-block:: python
 
    >>> server.add(1,2)
    3
    >>> server.subtract(3,2)
    1
    >>> server.batch_call(dict(
    ...   add = ((3, 2), {} ),
    ...   subtract = ((), {'a': 3, 'b': 2})
    ... ))
    [(5, None), (1, None)]
