+"""This module provides functions that will be builtins in Python 3.0,
+but that conflict with builtins that already exist in Python 2.x.
+
+Functions:
+
+hex(arg) -- Returns the hexadecimal representation of an integer
+oct(arg) -- Returns the octal representation of an integer
+ascii(arg) -- Same as repr(arg)
+map, filter, zip -- Same as itertools.imap, ifilter, izip
+
+The typical usage of this module is to replace existing builtins in a
+module's namespace:
+
+from future_builtins import hex, oct
+"""
