+ * @short_description: Access to the WebKit Inspector
+ *
+ * The WebKit Inspector is a graphical tool to inspect and change
+ * the content of a #WebKitWebView. It also includes an interactive
+ * JavaScriptDebugger. Using this class one can get a GtkWidget which
+ * can be embedded into an application to show the inspector.
+ *
+ * The inspector is available when the #WebKitWebSettings of the
+ * #WebKitWebView has set the #WebKitWebSettings:enable-developer-extras
+ * to true otherwise no inspector is available.
+ *
+ * <informalexample><programlisting>
+ * /<!-- -->* Enable the developer extras *<!-- -->/
+ * WebKitWebSettings *setting = webkit_web_view_get_settings (WEBKIT_WEB_VIEW(my_webview));
+ * g_object_set (G_OBJECT(settings), "enable-developer-extras", TRUE, NULL);
