+The MicroPython project aims to put an implementation of Python 3.x on
+microcontrollers and small embedded systems.
+MicroPython implements the entire Python 3.4 syntax (including exceptions,
+with, yield from, etc., and additionally async/await keywords from Python 3.5).
+The following core datatypes are provided: str (including basic Unicode
+support), bytes, bytearray, tuple, list, dict, set, frozenset, array.array,
+collections.namedtuple, classes and instances. Builtin modules include sys,
+time, and struct, etc. Select ports have support for _thread module
+(multithreading). Note that only a subset of Python 3 functionality is
+implemented for the data types and modules.
+MicroPython can execute scripts in textual source form or from precompiled
+bytecode, in both cases either from an on-device filesystem or "frozen" into
+the MicroPython executable.
