'''
To display information about Bokeh and Bokeh server configuration,
type ``bokeh info`` on the command line.
.. code-block:: sh
bokeh info
This will print general information to standard output, such as Python and Bokeh versions:
.. code-block:: none
Python version : 3.6.5
IPython version : 6.3.1
Bokeh version : 0.12.15
BokehJS static path : /opt/anaconda/lib/python3.6/site-packages/bokeh/server/static
node.js version : v8.11.1
npm version : 5.8.0
Sometimes it can be useful to get just paths to the BokehJS static files in order
to configure other servers or processes. To do this, use the ``--static`` option
.. code-block:: sh
bokeh info --static
This will produce output like what is shown below
.. code-block:: none
/opt/anaconda/lib/python3.6/site-packages/bokeh/server/static
