Empty values are not currently supported by ConfigObj. Are they standard 
in most other tools that use an 'ini style' format ?

I've never come across them before, but this is the second question 
about them in as many weeks.

ConfigObj supports ConfigParser style interpolation. Values to be 
interpolated *from* should be in the 'DEFAULT' section.

See the ConfigParser docs for the style of interpolation it uses :

    http://docs.python.org/lib/module-ConfigParser.html

And the ConfigObj docs for ConfigObj specific info :

    http://www.voidspace.org.uk/python/configobj.html#interpolation

Basically is uses '%(name)s', so the short answer would be no.

However, by using the ``walk`` method of ConfigObj and copying the 
interpolation code, it shouldn't be *that* hard to add yourself.

Lack of support for empty values may be a show stopper for you though.

All the best,
