OK, thanks.

In the long run, what do you suggest I implement for mayavi2, an object
oriented interface (pure TConfig) or an dictionnary-like interface
(your RcParamsWrapper)?

I am not too exited about your RcParamsWrapper because it is not
generated from the configuration object, and thus the info is duplicated,
but I guess you did this for backward compatibility reasons, and I could
use a canonical mapping from one to the other and do this automatically.

I would like to proivde an interface that feels familiar to the user,
this is why I am looking closely at what MPL and ipython are doing.

Cheers,
