- Note : starting with Python 2.7 ConfigParser is able to take into

- account the order of occurrences of the options into a file (by

- using an OrderedDict). If you have two options changing some common

- state, like a 'disable-all-stuff' and a 'enable-some-stuff-a', their

- order of appearance will be significant : the last specified in the

- file wins. For earlier version of python and logilab.common newer
