The ``translate_pypy`` script itself takes a number of options controlling
what to translate and how. See ``translate_pypy.py -h``. Some of the more
interesting options are:
+ * ``-text``: don't show the flowgraph after the translation is done. This
+ is useful if you don't have pygame installed.
* ``-llvm``: produce code for LLVM_ instead of for C. One of the biggest
things not working there is threading.
