+ * The root of wpa_supplicant configuration in registry is
+ * HKEY_LOCAL_MACHINE\SOFTWARE\wpa_supplicant. This level includes global
+ * parameters and a 'interfaces' subkey with all the interface configuration
+ * (adapter to confname mapping). Each such mapping is a subkey that has
+ * 'adapter' and 'config' values.
+ *
+ * This program can be run either as a normal command line application, e.g.,
+ * for debugging, with 'wpasvc.exe app' or as a Windows service. Service need
+ * to be registered with 'wpasvc.exe reg <full path to wpasvc.exe>'. After
+ * this, it can be started like any other Windows service (e.g., 'net start
+ * wpasvc') or it can be configured to start automatically through the Services
+ * tool in administrative tasks. The service can be unregistered with
+ * 'wpasvc.exe unreg'.
