+Example: polling for journal events
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This example shows that journal events can be waited for (using
+e.g. `poll`). This makes it easy to integrate Reader in an external
+event loop:
+
+ >>> import select
+ >>> from systemd import journal
+ >>> j = journal.Reader()
+ >>> j.seek_tail()
+ >>> p = select.poll()
+ >>> p.register(j, select.POLLIN)
+ >>> p.poll()
+ [(3, 1)]
+ >>> j.get_next()
