gaetk/configuration.py
This module provides a generic configuration object.
The two functions get_config and set_config are used
to get or set the configuration object.
>>> from gaetk import configuration
>>> configuration.get_config('MY-KEY-NAME')
None
>>> configuration.get_config('MY-KEY-NAME', default=55555)
55555
>>> configuration.set_config('MY-KEY-NAME', u'5711')
>>> configuration.get_config('MY-KEY-NAME')
u'5711'
