+setnet.sh is a simple state-less tool to manage and configure network
+interfaces. It is a shell wrapper around the functionalities of "ip",
+"dhclient", "wpa_cli", and can be used to configure network
+connections via Ethernet/Wi-Fi interfaces.
+
+Both Static and DHCP-based IP configuration is supported.
+
+At the moment, only WPA-PSK and open (no key) Wi-Fi connections are
+available.
