USAGE
-----

- Check out the appsconfig/ directory in the root of your Django tree.
- Create a "conf/" directory in the root of your Django tree.
- Under "conf/", create one directory per environment.  The default
  environment is "local".
- For each application, create a "(app).conf" configuration file.
- Default values for applications go in "conf/default/(app).conf"
- Each environment can create a settings.py file that will execute
  after the root settings.py
- You can load a different environment by running:
  ENV=production python manage.py runserver
- Variables that can be used in the configuration files:
  - environment: the directory of the environment being loaded
- In the root settings.py, load the config with:

# load configuration
from config import config
if config.settings():
    execfile(config.settings())
CONFIG = config.load()

- In an application, access the config with:
from settings import CONFIG
CONFIG.get('myapp', 'myvar')
