I'm interested to see how your bridging works.

Using the config module I released, access to environment variables is
very easy. Here's how:

1. Add the line

os : `os`

to your configuration (say, test.cfg).

2. Access it like this:

>>> from config import Config
>>> cfg = Config(file('test.cfg'))
>>> cfg.os.environ['OS']
'Windows_NT'

The point, of course, is that you can refer to environment variables
from elsewhere in your configuration, e.g.

temp_path: `os.environ['TEMP']`
work_file_prefix: $temp_path + `os.sep`
