/** Introspecting and controlling the loading of GSettings schemas.
 *
 * The SettingsSchemaSource and SettingsSchema APIs provide a
 * mechanism for advanced control over the loading of schemas and a
 * mechanism for introspecting their content.
 *
 * Plugin loading systems that wish to provide plugins a way to access
 * settings face the problem of how to make the schemas for these
 * settings visible to GSettings.  Typically, a plugin will want to ship
 * the schema along with itself and it won't be installed into the
 * standard system directories for schemas.
 *
 * SettingsSchemaSource provides a mechanism for dealing with this by
 * allowing the creation of a new 'schema source' from which schemas can
 * be acquired.  This schema source can then become part of the metadata
 * associated with the plugin and queried whenever the plugin requires
 * access to some settings.
