* This module describes the three encoder layers provided by libOggFLAC++.
*
* The libOggFLAC++ encoder classes are object wrappers around their
* counterparts in libOggFLAC. All three encoding layers available in
* libOggFLAC are also provided here. The interface is very similar;
* make sure to read the \link oggflac_encoder libOggFLAC encoder module \endlink.
*
* The only real difference here is that instead of passing in C function
* pointers for callbacks, you inherit from the encoder class and provide
* implementations for the callbacks in the derived class; because of this
* there is no need for a 'client_data' property.
