 wyebad is shared by clients, So even nowadays, browsers spawn procs for each windows,
 wyebad keeps single server proc that makes less memory and less cpu times.
-Don't worry, wyeb wills quit automatically when there is no client and 30 secs past.
 
 For exsample, while epiphay's webproc uses 240M RAM for
 [a page](http://simple-adblock.com/faq/testing-your-adblocker/), wyeb uses 160M for the same page.
 Of course the adblock uses 80M but not gain.

+If you want full control of wyebab as wyeb does, wyebab has api mode.
+Set string ";wyebabapi;" as the extensions_init's data.
+In api mode wyebab doesn't block URIs but keeps alive server proc and
+set the check function to the page object.
+So you can call the check func at where ever as below.
+
+	bool (*checkf)(const char *, const char *) =
+		g_object_get_data(G_OBJECT(webkitwebpage), "wyebcheck");
