Dear Paddle-Lite developers and Project Managers:

1. Given that Caffe is a widely-used framework in industry (NNIE only supports Caffe, ncnn supports Caffe at a very early stage, etc). I am humbly requesting a potential feature: Paddle2Caffe, maybe Paddle2X as a counterpart of X2Paddle.
2. Also it is good to have an automatic model optimization tool which analyzes backend properties and choose the most appropriate kernel out of the implemented ones, it might not be a bad idea to offer a 100% manually overwritable kernel specification tool. Cause, the meaning of "the most appropriate kernel" truly depends on use cases.
3. And many thanks have already been given to this well-considered training framework (PaddlePaddle) and the super-fast inference framework (Paddle-Lite). Excellent works!
4. Apologize if this is not a good place for filing feature requests.
