Passwords on OS X via security

[Lucien Pullen]

The `keyring' package is installed with either pip or easy_install.  It
is not distributed with Python.

This will not work, unless I'm trying to use anonymous functions
incorrectly.  Calling "import foo" from a lambda will result in an
error (Python 2.7):

--8<---------------cut here---------------start------------->8---
>>> lambda: import keyring
  File "<stdin>", line 1
    lambda: import keyring
                 ^
SyntaxError: invalid syntax
--8<---------------cut here---------------end--------------->8---

You will need to perform any imports in a .py file.  You mentioned that
an auxiliary file was unwanted, but you may need one.

That or a config option for loading dependent libraries needs to be
added (very specific change for a very specific problem, but that's the
only reason I use a .py file, so maybe an ok one if enough people do
that).
