I have some question about this:
1) I am reading how .mo files work and i see that the folder of my locale need to be:
/locale/de_DE/LC_MESSAGES/domainname.mo
Wordpress and others have different path as: /locale/de_DE.mo /locale/it_IT.mo etc.
How can I set the second strategy?
2) in setlocale() can O use something else other than it_IT, de_DE? I want use this. Is it possible?
