Description:
header files for PyPy (an alternative Python interpreter)
Header files for compiling cpython C extension modules for use with PyPy. Note that pure Python modules will probably perform better. . PyPy supports a subset of cpython's C API through its CPyExt subsystem. . Also included is PyPy.h, for embedding the PyPy interpreter. . PyPy is a fast, compliant alternative implementation of the Python language (2.7).
