+PyPy is a fast, compliant alternative implementation of the Python language
+(2.7.18). It has several advantages and distinct features:
+
+ - Speed: thanks to its Just-in-Time compiler, 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.
+ - Sandboxing: PyPy provides the ability to run untrusted code in a fully
+               secure way.
+ - Stackless: PyPy can be configured to run in stackless mode, providing
+              micro-threads for massive concurrency.
+ - As well as other features.
