It is a shell wrapper around the functionalities of standard command-line tools, including "ip", "dhclient", "wpa_cli", etc., and can be used to configure network connections via Ethernet/Wi-Fi interfaces. Both Static and DHCP-based IP configuration are supported. At the moment, only WPA-PSK and open (no key) Wi-Fi connections are available.
