+"""
+A resurrection of some old functions from Python 2 for use in Python 3. These
+should be used sparingly, to help with porting efforts, since code using them
+is no longer standard Python 3 code.
+
+This module provides the following:
+
+1. Implementations of these builtin functions which have no equivalent on Py3:
+
+- apply
+- chr
+- cmp
+- execfile
+
+2. Aliases:
+
+- intern <- sys.intern
+- raw_input <- input
+- reduce <- functools.reduce
+- reload <- imp.reload
+- unichr <- chr
+- unicode <- str
+- xrange <- range
+
+3. List-producing versions of the corresponding Python 3 iterator-producing functions:
+
+- filter
+- map
+- range
+- zip
+
+4. Forward-ported Py2 types:
+
+- basestring
+- dict
+- str
+- long
+- unicode
+
