[Tutor] Simple way for i18n ?

[francois schnell]

Hello Micheal,

I've  changed LANGUAGE in the shell , it worked at the beginning and then it
stopped working ...
Also os.environ.setdefault method still has no effect. I begin to wonder if
it's specific to my distro (Ubuntu Breezy).

Anyway I managed to use "translation" but if I give None for languages (or
nothing) he gives back an IOError.

I'm finaly using a mix of "install" and "translation" through an exception
handling and I can also change the language on the fly in the app.
It works but it's probably not very "academic"  :)

Thanks
francois
