     1.4 +Cython is an optimising static compiler for both the Python programming
     1.5 +language and the extended Cython programming language (based on Pyrex).
     1.6 +It makes writing C extensions for Python as easy as Python itself.
     1.7 +
     1.8 +Cython gives you the combined power of Python and C to let you
     1.9 +
    1.10 +- write Python code that calls back and forth from and to C or C++ code
    1.11 +  natively at any point.
    1.12 +- easily tune readable Python code into plain C performance by adding
    1.13 +  static type declarations, also in Python syntax.
    1.14 +- use combined source code level debugging to find bugs in your Python,
    1.15 +  Cython and C code.
    1.16 +- interact efficiently with large data sets, e.g. using multi-dimensional
    1.17 +  NumPy arrays.
    1.18 +- quickly build your applications within the large, mature and widely
    1.19 +  used CPython ecosystem.
    1.20 +- integrate natively with existing code and data from legacy, low-level
    1.21 +  or high-performance libraries and applications.
    1.22 +
    1.23 +The Cython language is a superset of the Python language that additionally
    1.24 +supports calling C functions and declaring C types on variables and class
    1.25 +attributes. This allows the compiler to generate very efficient C code
    1.26 +from Cython code.
    1.27 +The C code is generated once and then compiles with all major C/C++
    1.28 +compilers in CPython 2.6, 2.7 (2.4+ with Cython 0.20.x) as well as 3.3
    1.29 +and all later versions.
    1.30 +We regularly run integration tests against all supported CPython versions
    1.31 +and their latest in-development branches to make sure that the generated
    1.32 +code stays widely compatible and well adapted to each version.
    1.33 +PyPy support is work in progress (on both sides) and is considered mostly
    1.34 +usable since Cython 0.17. The latest PyPy version is always recommended here.
    1.35 +
    1.36 +All of this makes Cython the ideal language for wrapping external C libraries,
    1.37 +embedding CPython into existing applications, and for fast C modules that
    1.38 +speed up the execution of Python code.
