pygettext ?

[cantabile]

Hi, I'm trying to write an internationalized app. I'm learning python 
and read that pygettext would help me, but I found elsewhere it was 
obsolete (??)
So, what's the correct and up to date tool to i18n python ?
Is there a tutorial somewhere (python docs has nothing really usable : 
I'd like at least an example!)

Do you have links to pages or documents about that ?

Thanks :)
