r"""jc - JSON Convert `ifconfig` command output parser

No `ifconfig` options are supported.

Consider using the `ip` command instead of `ifconfig` as it supports native
JSON output.

Usage (cli):

    $ ifconfig | jc --ifconfig

or

    $ jc ifconfig

Usage (module):

    import jc
    result = jc.parse('ifconfig', ifconfig_command_output)

    [0] these fields only pick up the last IP address in the interface
        output and are here for backwards compatibility. For information on
        all IP addresses, use the `ipv4` and `ipv6` objects which contain an
        array of IP address objects.
