title: Django: What's the purpose of the LANGUAGE_CODE setting?
body: <p>I've made a prototype site with working i18n text translations. But whatever I put in LANGUAGE_CODE setting in the settings.py, I see no effect on my pages. It seems to be always overridden by the locale finder middleware.
  The django's documentation does not give much explanations. What's the true purpose of this setting?</p>
