Description: musette
        =======
        
        ``musette`` enables application configuration by providing a proxy to
        ``os.environ`` which allows:
        
        + type-casting of environment values
        + updating the environment via plaintext key-value properties files
        + shell-style interpolation
        
        ``musette`` is a direct fork of `django-environ`_ with significant changes.
        Although it is intended for Django settings configuration it does not actually
        require Django itself.
        
        The original module (`django-environ`_) was a merge of:
        
        + `envparse`_
        + `honcho`_
        + `dj-database-url`_
        + `dj-search-url`_
        + `dj-config-url`_
        + `django-cache-url`_
        
        Basic usage
        -----------
        
        ::
        
            from musette import environ
        
            environ.read('env.properties')
        
            DEBUG = environ.bool("DEBUG")
        
        
        Django Settings
        ---------------
        
        This is your `settings.py` file before you have installed **musette**::
        
            DEBUG = True
            TEMPLATE_DEBUG = DEBUG
        
            DATABASES = {
                'default': {
                    'ENGINE': 'django.db.backends.postgresql_psycopg2',
                    'NAME': 'database',
                    'USER': 'user',
                    'PASSWORD': 'githubbedpassword',
                    'HOST': '127.0.0.1',
                    'PORT': '8458',
                }
                'extra': {
                    'ENGINE': 'django.db.backends.sqlite3',
                    'NAME': 'database.sqlite'
                }
            }
        
            SECRET_KEY = 'notsecret'
        
            CACHES = {
                'default': {
                    'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
                    'LOCATION': [
                        '127.0.0.1:11211', '127.0.0.1:11212', '127.0.0.1:11213',
                    ]
                },
                'redis': {
                    'BACKEND': 'redis_cache.cache.RedisCache',
                    'LOCATION': '127.0.0.1:6379:1',
                    'OPTIONS': {
                        'CLIENT_CLASS': 'redis_cache.client.DefaultClient',
                        'PASSWORD': 'redis-githubbed-password',
                    }
                }
            }
        
        After::
        
            from musette import Environment
        
            env = Environment(DEBUG=(bool, False),)
            env.read('env.properties')
        
            DEBUG = env('DEBUG') # False if not in os.environ
            TEMPLATE_DEBUG = DEBUG
        
            DATABASES = {
                'default': env.db(),
                'extra': env.db('SQLITE_URL', default='sqlite:////tmp/my-tmp-sqlite.db')
            }
        
            SECRET_KEY = env('SECRET_KEY')
        
            CACHES = {
                'default': env.cache(),
                'redis': env.cache('REDIS_URL')
            }
        
        Properties Files
        ----------------
        
        A properties or "env" file is plain text file containing one or more
        **key := value** or **key = value** lines, where values may optionally
        refer to other environment values via shell-style variables::
        
            that := something
            this := ${that}
        
        
        How to install
        --------------
        
        ::
        
            $ pip install musette
        
        
        How to use
        ----------
        
        There is an ``Environment`` class and a convenient instance of that class
        called ``environ``.
        
        ::
        
            >>> from musette import Environment
            >>> env = Environment(
                    DEBUG=(bool, False),
                )
            >>> env('DEBUG')
            False
            >>> env('DEBUG', default=True)
            True
        
            >>> open('.myenv', 'a').write('DEBUG=on\n')
            >>> env.read('.myenv')
            >>> env('DEBUG')
            True
        
            >>> open('.myenv', 'a').write('INT_VAR=1010\n')
            >>> env.read('.myenv')
            >>> env.int('INT_VAR'), env.str('INT_VAR')
            1010, '1010'
        
            >>> open('.myenv', 'a').write('DATABASE_URL=sqlite:///my-local-sqlite.db\n')
            >>> env.read('.myenv')
            >>> env.db()
            {'ENGINE': 'django.db.backends.sqlite3', 'NAME': 'my-local-sqlite.db', 'HOST': '', 'USER': '', 'PASSWORD': '', 'PORT': ''}
        
        ``Environment`` by default provides an effective proxy to the ``os.environ``
        data dictionary, but you can pass in any other dict instead::
        
            >>> from musette import Environment
            >>> _environ = {}
            >>> env = Environment(_environ, DEBUG=True)
            >>> _environ['DEBUG']
            True
        
        If you are neither passing in a configuration dict or any schema values then
        you can just use the ``environ`` instance::
        
            >>> import os
            >>> from musette import environ
            >>> set(os.environ.keys()) == set(environ.keys())
            True
