'''
To generate the serialized JSON representation for a Bokeh application
from a single Python script, pass the script name to ``bokeh json`` on the
command line:

.. code-block:: sh

    bokeh json app_script.py

The generated JSON will be saved in the current working directory with
the name ``app_script.json``.

Applications can also be created from directories. The directory should
contain a ``main.py`` (and any other helper modules that are required) as
well as any additional assets (e.g., theme files). Pass the directory name
to ``bokeh json`` to generate the JSON:

.. code-block:: sh

    bokeh json app_dir

By default, the generated JSON is output as one line, with no indentation.
To generate "pretty printed" JSON on multiple lines, you can specify an
indentation level with the ``--indent`` argument:

.. code-block:: sh

    bokeh json app_script.py --indent=2
