+# setnet.sh #
+
+This is a simple bash+dialog script to configure and manage network
+interfaces. At the moment, it is only able to bring up ethernet and
+wi-fi networks (WPA/WPA2/ESS), using either static or dhcp-based IP
+configuration.
+
+## Dependencies ##
+
+setnet.sh depends on the following packages:
+
+- bash (maybe dash/sh could be enough...)
+- dialog
+- wpa_supplicant
+- dhclient
+- iproute2
+

+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.
