pypy 2.3.1+dfsg-1 (i386 binary) in ubuntu utopic

 PyPy is a fast, compliant alternative implementation of the Python language
 (2.7). It has several advantages and distinct features:
  * Speed: thanks to its Just-in-Time compiler (on x86), Python programs often
    run faster on PyPy.
  * Memory usage: large, memory-hungry Python programs might end up taking less
    space than they do in CPython.
  * Compatibility: PyPy is highly compatible with existing Python code.
    It supports ctypes and can run popular Python libraries like twisted and
    django.
  * Stackless: PyPy supports stackless mode on x86, providing
    micro-threads for massive concurrency.

 This package contains the PyPy interpreter.
