+past.translation
+==================
+
+The ``past.translation`` package provides an import hook for Python 3 which
+transparently runs ``futurize`` fixers over Python 2 code on import to convert
+print statements into functions, etc.
+
+It is intended to assist users in migrating to Python 3.x even if some
+dependencies still only support Python 2.x.
+
+Usage
+-----
+
+Once your Py2 package is installed in the usual module search path, the import
+hook is invoked as follows:
+
+    >>> from past.translation import autotranslate
+    >>> autotranslate('mypackagename')
+
+Or:
+
+    >>> autotranslate(['mypackage1', 'mypackage2'])
+
+You can unregister the hook using::
+
+    >>> from past.translation import remove_hooks
+    >>> remove_hooks()
+
+Author: Ed Schofield.
+Inspired by and based on ``uprefix`` by Vinay M. Sajip.
