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 most platforms, providing micro-threads for massive concurrency.

This package contains the PyPy interpreter.
