 In the example above, the refresh is `0`. This means that the module *will never
 refresh on its own*; it will wait for the RTMIN+1 signal. You may also configure

 Unfortunately, to send the signal, you cant just `pkill easyconf-lemonbar`. You
 have to read the PID from eclb's pidfile. I would recommend creating an alias in
