+pasteurize: automatic conversion of Python 3 code to clean 2/3 code
+===================================================================
+
+``pasteurize`` attempts to convert existing Python 3 code into source-compatible
+Python 2 and 3 code.
+
+Use it like this on Python 3 code:
+
+  $ pasteurize --verbose mypython3script.py
+
+This removes any Py3-only syntax (e.g. new metaclasses) and adds these
+import lines:
+
+    from __future__ import absolute_import
+    from __future__ import division
+    from __future__ import print_function
+    from __future__ import unicode_literals
+    from future import standard_library
+    standard_library.install_hooks()
+    from builtins import *
+
+To write changes to the files, use the -w flag.
+
+It also adds any other wrappers needed for Py2/3 compatibility.
+
+Note that separate stages are not available (or needed) when converting from
+Python 3 with ``pasteurize`` as they are when converting from Python 2 with
+``futurize``.
+
+The --all-imports option forces adding all ``__future__`` imports,
+``builtins`` imports, and standard library aliases, even if they don't
+seem necessary for the current state of each module. (This can simplify
+testing, and can reduce the need to think about Py2 compatibility when editing
+the code further.)
