+ (description "MicroPython is a lean and efficient implementation of the
+Python 3 programming language that includes a small subset of the Python
+standard library and is optimised to run on microcontrollers and in constrained
+environments. MicroPython is packed full of advanced features such as an
+interactive prompt, arbitrary precision integers, closures, list comprehension,
+generators, exception handling and more. Still it is compact enough to fit and
+run within just 256k of code space and 16k of RAM. MicroPython aims to be as
+compatible with normal Python as possible to allow you to transfer code with
+ease from the desktop to a microcontroller or embedded system.")
