Cool LM317 with a parallel transistor for current?

Hi!
Iím looking for a circuit using LM317 and then you have a transistor parallel that take all the current.
LM317 sense changes in load, input or temperature and that mirrors in the transistor.

Have a small picture about it.

I need help with the circuit and components. I need about 15V and 5A., negative and positive supply. For the negative I use LM337.

Regard

Take note of the pass transistor dissipation though.
