The libraries in this directory aim to provide compatible implementations of standard libraries to allow existing Python code to run un-modified on MicroPython.

Many libraries are implemented in pure Python, often based on the original CPython implementation. (e.g. collections.defaultdict)

Some libraries are based on or extend from the built-in "micro" modules in the MicroPython firmware, providing additional functionality that didn't need to be written in C (e.g. collections, socket, struct).

• Add README.md to each library explaining compatibility and limitations.
