Don't use this option for the time being.

It depends on an OTP extension, namely the ability to specify types of 
callbacks, which has been sitting in 'pu' for more than 8 months now. 
It has not made it to 'dev', let alone in the release, yet. Once the 
behaviour modules of OTP will have the necessary information, this 
option will be safe to use.
