+past: compatibility with Python 2 from Python 3
+===============================================
+
+``past`` is a package to aid with Python 2/3 compatibility. Whereas ``future``
+contains backports of Python 3 constructs to Python 2, ``past`` provides
+implementations of some Python 2 constructs in Python 3 and tools to import and
+run Python 2 code in Python 3. It is intended to be used sparingly, as a way of
+running old Python 2 code from Python 3 until the code is ported properly.
+
+Potential uses for libraries:
+
+- as a step in porting a Python 2 codebase to Python 3 (e.g. with the ``futurize`` script)
+- to provide Python 3 support for previously Python 2-only libraries with the
+ same APIs as on Python 2 -- particularly with regard to 8-bit strings (the
+ ``past.builtins.str`` type).
+- to aid in providing minimal-effort Python 3 support for applications using
+ libraries that do not yet wish to upgrade their code properly to Python 3, or
+ wish to upgrade it gradually to Python 3 style.
+
+
+Here are some code examples that run identically on Python 3 and 2::
+
+ >>> from past.builtins import str as oldstr
+
+ >>> philosopher = oldstr(u'\u5b54\u5b50'.encode('utf-8'))
+ >>> # This now behaves like a Py2 byte-string on both Py2 and Py3.
+ >>> # For example, indexing returns a Python 2-like string object, not
+ >>> # an integer:
+ >>> philosopher[0]
+ '\xe5'
+ >>> type(philosopher[0])
+ <past.builtins.oldstr>
+
+ >>> # List-producing versions of range, reduce, map, filter
+ >>> from past.builtins import range, reduce
+ >>> range(10)
+ [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
+ >>> reduce(lambda x, y: x+y, [1, 2, 3, 4, 5])
+ 15
+
+ >>> # Other functions removed in Python 3 are resurrected ...
+ >>> from past.builtins import execfile
+ >>> execfile('myfile.py')
+
+ >>> from past.builtins import raw_input
+ >>> name = raw_input('What is your name? ')
+ What is your name? [cursor]
+
+ >>> from past.builtins import reload
+ >>> reload(mymodule) # equivalent to imp.reload(mymodule) in Python 3
+
+ >>> from past.builtins import xrange
+ >>> for i in xrange(10):
+ ... pass
+
+
+It also provides import hooks so you can import and use Python 2 modules like
+this::
+
+ $ python3
+
+ >>> from past.translation import autotranslate
+ >>> authotranslate('mypy2module')
+ >>> import mypy2module
+
+until the authors of the Python 2 modules have upgraded their code. Then, for
+example::
+
+ >>> mypy2module.func_taking_py2_string(oldstr(b'abcd'))
