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

Supports the following `bluetoothctl` subcommands:
- `bluetoothctl list`
- `bluetoothctl show`
- `bluetoothctl show <ctrl>`
- `bluetoothctl devices`
- `bluetoothctl info <dev>`

Usage (cli):

    $ bluetoothctl info <dev> | jc --bluetoothctl
or

    $ jc bluetoothctl info <dev>

Usage (module):

    import jc
    result = jc.parse('bluetoothctl', bluetoothctl_command_output)

Schema:

Because bluetoothctl is handling two main entities, controllers and devices,
the schema is shared between them. Most of the fields are common between
a controller and a device but there might be fields corresponding to one entity.

    Controller:
    [
        {
            "manufacturer":         string,
            "version":              string,
            "name":                 string,
            "is_default":           boolean,
            "is_public":            boolean,
            "is_random":            boolean,
            "address":              string,

            "class":                string,

            "uuids":                array
        }
    ]

    Device:
    [
        {
            "name":                 string,
            "is_public":            boolean,

            "appearance":           string,
            "class":                string,
            "icon":                 string,
            "paired":               string,
            "bonded":               string,
            "trusted":              string,
            "blocked":              string,
            "connected":            string,
            "legacy_pairing":       string,
            "rssi":                 int,
