+ * This file implements a configuration backend for Windows registry. All the
+ * configuration information is stored in the registry and the format for
+ * network configuration fields is same as described in the sample
+ * configuration file, wpa_supplicant.conf.
+ *
+ * Configuration data is in
+ * \a HKEY_LOCAL_MACHINE\\SOFTWARE\\%wpa_supplicant\\configs
+ * key. Each configuration profile has its own key under this. In terms of text
+ * files, each profile would map to a separate text file with possibly multiple
+ * networks. Under each profile, there is a networks key that lists all
+ * networks as a subkey. Each network has set of values in the same way as
+ * network block in the configuration file. In addition, blobs subkey has
+ * possible blobs as values.
+ *
+ * Example network configuration block:
+ * \verbatim
+HKEY_LOCAL_MACHINE\SOFTWARE\wpa_supplicant\configs\test\networks\0000
+ ssid="example"
+ key_mgmt=WPA-PSK
