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.
