How to make atutor not check for user's browser language?

Question

as you know atutor checks for user's browser first to detect the language and if it cannot find it, it uses the default language set by the administrator. I searched and found the code, do you know how I can change it so that atutor directly uses the default language and not check for user's first?

    /**
* Tries to detect the user's current language preference/setting from (in order):
* _GET, _POST, _SESSION, HTTP_ACCEPT_LANGUAGE, HTTP_USER_AGENT. If no match can be made
* then it tries to detect a default setting (defined in config.inc.php) or a fallback
* setting, false if all else fails.
* @access   public
* @return   boolean|Language    Returns a Language Object matching the user's current session.
*                               Returns FALSE if a valid Language Object cannot be found
*                               to match the request
* @see      getLanguage()

You should just need to comment out this chunk:

if (!empty($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {

    // Language is not defined yet :
    // try to find out user's language by checking its HTTP_ACCEPT_LANGUAGE
    $accepted    = explode(',', $_SERVER['HTTP_ACCEPT_LANGUAGE']);
    $acceptedCnt = count($accepted);
    reset($accepted);
    for ($i = 0; $i < $acceptedCnt; $i++) {
        foreach ($this->availableLanguages as $codes) {
            foreach ($codes as $language) {
                if ($language->isMatchHttpAcceptLanguage($accepted[$i])) {
                    return $language;
                }
            }
        }
    }
}
