+setnet.sh is a simple state-less tool to manage and configure network
+interfaces. 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.
