Hey, wait, that's not enough! There are even more options since we (the 
PyPy Project) also have the LLInterpreter. This is an interpreter for 
low level flow graphs, the intermediate representation that our 
translator produces (very useful for debugging). Therefore you also have:

CPython interpreting the LLInterpreter interpreting PyPy interpreting 
pystone (verrrrrry slow, nobody ever waited for even the end of the 
parsing of pystone on the llinterpreted PyPy)

and

CPython interpreting LLInterpreter interpreting pystone  :-)
