bindings = ExtensionPoint(

This extension point allows you to contribute name/value pairs that
will be bound when the interactive Python shell is started.
e.g. Each item in the list is a dictionary of name/value pairs::
{'x' : 10, 'y' : ['a', 'b', 'c']}
"""
)
commands = ExtensionPoint(
List(Str), id=COMMANDS, desc="""
This extension point allows you to contribute commands that are
executed when the interactive Python shell is started.
e.g. Each item in the list is a string of arbitrary Python code::
'import os, sys'
'from enthought.traits.api import *'
Yes, I know this is insecure but it follows the usual Python rule of
'we are all consenting adults'.
