===================================== PyPy: Python in Python Implementation ===================================== Welcome to PyPy! PyPy is both an implementation of the Python programming language, and an extensive compiler framework for dynamic language implementations. You can build self-contained Python implementations which execute independently from CPython. The home page is: If you want to help developing PyPy, this document might help you: It will also point you to the rest of the documentation which is generated from files in the pypy/doc directory within the source repositories. Enjoy and send us feedback! the pypy-dev team <> Building ======== build with:: rpython/bin/rpython -Ojit pypy/goal/ This ends up with ``pypy-c`` binary in the main pypy directory. We suggest to use virtualenv with the resulting pypy-c as the interpreter, you can find more details about various installation schemes here:
