+Standard Library for RustPython
+===============================
+
+This directory contains all of the Python files that make up the standard library for RustPython.
+
+Most of these files are copied over from the CPython repository(the 3.7 branch), with slight modifications to allow them 
+to work under RustPython. The current goal is to complete the standard library with as few modifications as possible. 
+Current modifications are just temporary workarounds for bugs/missing feature within the RustPython implementation.
+
+The first target is to run the ``unittest`` module, so we can leverage the CPython test suite.
