+
+    Adds necessary hooks to allow Python code to run on multiple major versions of Python at once
+    (currently 2.6 - 3.x)
+
+    Usage:
+        Anywhere you want to gain support for multiple versions of Python simply add the following two lines
+            from __future__ import absolute_import, division, print_function, unicode_literals
+            from pies.overrides import *
+
+        And for changed stdlibs:
+            from pies import [libname]
