-// Windows Vista uses the Native Wifi (WLAN) API for accessing WiFi cards. See
-// http://msdn.microsoft.com/en-us/library/ms705945(VS.85).aspx. Windows XP
-// Service Pack 3 (and Windows XP Service Pack 2, if upgraded with a hot fix)
-// also support a limited version of the WLAN API. See
-// http://msdn.microsoft.com/en-us/library/bb204766.aspx. The WLAN API uses
-// wlanapi.h, which is not part of the SDK used by Gears, so is replicated
-// locally using data from the MSDN.
-//\
-// Windows XP from Service Pack 2 onwards supports the Wireless Zero
-// Configuration (WZC) programming interface. See
-// http://msdn.microsoft.com/en-us/library/ms706587(VS.85).aspx.
-//
-// The MSDN recommends that one use the WLAN API where available, and WZC
-// otherwise.
-//
-// However, it seems that WZC fails for some wireless cards. Also, WLAN seems
-// not to work on XP SP3. So we use WLAN on Vista, and use NDIS directly
-// otherwise.
