 Motivation
 ===========
+
 * PyPy grew out of a desire to modify/extend
   the implementation of Python, for example to:
 * increase performance (psyco-style JIT
   compilation, better garbage collectors)
 * add expressiveness (stackless-style

 * ease porting (to new platforms like the
   JVM or CLI or to low memory situations)
