Hello:

I've looked around, but haven't dug up anything regarding my question.

I know how to localize a Cocoa application for various languages 
(English, Dutch, German, etc.).  But is there a way to create 
different dialects of a language?  Such as, is there a way to localize 
(or localise) an application so it is aware of say U.S. English versus 
British English?

I imagine something similar might even pertain to other variants, such 
as Swiss German, versus High German, or Western Spanish versus 
European Spanish, etc.

Regards,

Chad
