+"""This is the implementation of the Google News engine.
+
+Google News has a different region handling compared to Google WEB.
+
+- the ``ceid`` argument has to be set (:py:obj:`ceid_list`)
+- the hl_ argument has to be set correctly (and different to Google WEB)
+- the gl_ argument is mandatory
+
+If one of this argument is not set correctly, the request is redirected to
+CONSENT dialog::
+
+  https://consent.google.com/m?continue=
+
+The google news API ignores some parameters from the common :ref:`google API`:
+
+- num_ : the number of search results is ignored / there is no paging all
+  results for a query term are in the first response.
+- save_ : is ignored / Google-News results are always *SafeSearch*
