/**

 * @short_description: Describes Proxy Url, Script and other related properties
 *
 * The #NMSettingProxy object is a #NMSetting subclass that describes properties
 * related to Proxy settings like Pac Url, Pac Script etc.
 *
 * NetworkManager support 3 values for the #NMSettingProxy:method property for
 * proxy. If "auto" is specified then WPAD takes places and the appropriate details
 * are pushed into PacRunner or user can override this URL with a new PAC url or a
 * PAC Script. If "manual" is selected then users can specify different proxy servers
 * for different protocols. If "none" is selected then no proxy configuration is given
 * to PacRunner to fulfill client queries.
