# description: wpa_supplicant is an implementation of the WPA Supplicant \
#	       component, i.e., the part that runs in the client stations. \
#	       It implements WPA key negotiation with a WPA Authenticator \
#	       and EAP authentication with Authentication Server. In \
#	       addition, it controls the roaming and IEEE 802.11 \
#	       authentication/association of the wlan driver.
