Daniel,

The _Erlang Programming_ book actually says **not** to implement callbacks
you don't need. (pp274)  I think that makes sense and is the advice I have
followed.  However, most people tend to implement all the callbacks even if
they don't use them for anything.  In fact, I think that's the recommended
way in _OTP in Action_.  So it seems not even the veterans can agree on this
topic.
