    // We handle languages using a hierarchy of translations.  The top of the hierarchy is default.  This includes a default translation for all items
    // (most likely using simple English).  The next level is the language: for instance, English, French, Chinese, etc.  This file should contain a
    // generic translation for all items which differ from default.  Finally there is the locale.  This is region-specific items which differ from the
    // language file.  These files must be name in the format <Language> (<LC>), where Language is the name of the language which it inherits from,
    // and LC is the local code.  Some examples of this would be English (US) (American English), French (FR) (France French), French (CA) (Canadian
    // French), etc.
    //
    // Each level will only contain the differences between itself and its parent translation.  For instance, English (UK) or English (CA) may
    // include the translation "HISTORY_MSG_34;Avoid Colour Clipping" where English would translate it as "HISTORY_MSG_34;Avoid Color Clipping" (note
    // the difference in the spelling of 'colour').
    //
    // It is important that when naming the translation files, that you stick to the format <Language> or <Language> (<LC>).  We depend on that to figure
    // out which are the parent translations.  Furthermore, there must be a file <Language> for each locale <Language> (<LC>) -- you cannot have
    // 'French (CA)' unless there is a file 'French'.
