+#  Do
+#    ln -s /path/to/openweather_ openweather_<type>_<id>
+#  where <type> is currently ignored (formerly one of
+#  [station, weather]) and <id> is a suitable
+#  city id from http://openweathermap.org/
+#  These parameters translate directly into a URL formed like this:
+#    http://openweathermap.org/data/<api>/weather?id=<id>
+#
+# Example config:
+#  [openweather_*]
+#
