+#    MODE: Ad-Hoc, Managed, etc.
+#    ESSID: Name of the wireless network
+#    NWID: Name of this machine on the network.  Hostname is default
+#    FREQ: Frequency to operate on.  See CHANNEL
+#    CHANNEL: Numbered frequency to operate on.  See FREQ
+#    SENS: Sensitivity threshold for packet rejection.
+#    RATE: Transfer rate.  Usually one of Auto, 11, 5, 2, or 1.
+#    KEY: Encryption key for WEP.
+#    RTS: Explicit RTS handshake.  Usually not specified (auto)
+#    FRAG: Fragmentation threshold to split packets.  Usually not specified.
+#    SPYIPS: List of IP addresses to "spy" on for link performance stats.
+#    IWCONFIG: Extra parameters to pass directly to IWCONFIG
+#    IWPRIV: Extra parameters to pass directly to IWPRIV
