Options
=======
The options below are convenience aliases to configurable class-options,
as listed in the "Equivalent to" description-line of the aliases.
To see all configurable class-options for some <cmd>, use:
    <cmd> --help-all

--debug
    set log level to logging.DEBUG (maximize logging output)
    Equivalent to: [--Application.log_level=10]
--kernel=<Unicode>
    The name of a kernel type to start
    Default: 'python3'
    Equivalent to: [--KernelApp.kernel_name]
--ip=<Unicode>
    Set the kernel's IP address [default localhost]. If the IP address is
    something other than localhost, then Consoles on other machines will be able
    to connect to the Kernel, so be careful!
    Default: ''
    Equivalent to: [--KernelManager.ip]

To see all available configurables, use `--help-all`.
