/**
 * SECTION: WebKitWebsiteDataManager
 * @Short_description: Website data manager
 * @Title: WebKitWebsiteDataManager
 * @See_also: #WebKitWebContext, #WebKitWebsiteData
 *
 * WebKitWebsiteDataManager allows you to manage the data that websites
 * can store in the client file system like databases or caches.
 * You can use WebKitWebsiteDataManager to configure the local directories
 * where the Website data will be stored, by creating a new manager with
 * webkit_website_data_manager_new() passing the values you want to set.
 * You can set all the possible configuration values or only some of them,
 * a default value will be used automatically for the configuration options
 * not provided. #WebKitWebsiteDataManager:base-data-directory and
 * #WebKitWebsiteDataManager:base-cache-directory are two special properties
 * that can be used to set a common base directory for all Website data and
 * caches. It's possible to provide both, a base directory and a specific value,
 * but in that case, the specific value takes precedence over the base directory.
 * The newly created WebKitWebsiteDataManager must be passed as a construct property
 * to a #WebKitWebContext, you can use webkit_web_context_new_with_website_data_manager()
 * to create a new #WebKitWebContext with a WebKitWebsiteDataManager.
 * In case you don't want to set any specific configuration, you don't need to create
 * a WebKitWebsiteDataManager, the #WebKitWebContext will create a WebKitWebsiteDataManager
 * with the default configuration. To get the WebKitWebsiteDataManager of a #WebKitWebContext
 * you can use webkit_web_context_get_website_data_manager().
 *
 * A WebKitWebsiteDataManager can also be ephemeral and then all the directories configuration
 * is not needed because website data will never persist. You can create an ephemeral WebKitWebsiteDataManager
 * with webkit_website_data_manager_new_ephemeral(). Then you can pass an ephemeral WebKitWebsiteDataManager to
 * a #WebKitWebContext to make it ephemeral or use webkit_web_context_new_ephemeral() and the WebKitWebsiteDataManager
 * will be automatically created by the #WebKitWebContext.
 *
 * WebKitWebsiteDataManager can also be used to fetch websites data, remove data
 * stored by particular websites, or clear data for all websites modified since a given
 * period of time.
 *
 * Since: 2.10
