Function Documentation

string anyMealLanguage ( void   ) 

Wrapper for getting current language from KDE or using getenv. This method will first try to call 

    KGlobal::locale()->language()
If there is no KLocale object, 'en' will be returned.
Returns:
The two-letter language code (ISO 639-1 standard).
