- * \brief
- * This module describes the encoder layers provided by libOggFLAC++.
- *
- * The libOggFLAC++ encoder classes are object wrappers around their
- * counterparts in libOggFLAC. Only the stream encoding layer in
- * libOggFLAC is 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.
