Configuration options
These options can be set in the configuration file,
~/.jupyter/jupyter_qtconsole_config.py
, or
at the command line when you start Qt console.
You may enter jupyter qtconsole --help-all
to get information
about all available configuration options.

- KernelManager.connection_fileUnicode
Default:
''
JSON file in which to store connection info [default: kernel-<pid>.json]
