+ * network configuration fields is same as described in the sample
+ * configuration file, wpa_supplicant.conf.
+ *
+ * Configuration data is in 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.
