GetCVar for game build type?

[Halja]

I know this is probably a loaded question...

Is the global ["SETTING_TYPE_LANGUAGE"] just what language the client is running under? Can I detect the game build language/type? ["_VERSION"] is build number only right?

I'm getting reports for my add-on which make me think there is a build difference between US and EU. I see that the game has GetCVar. I'm at work at the moment and have not poked and/or peek with it yet. I was hoping some already know if the is a CVar for US or EU build in game memory.
