Seems awefully academic to me but if that's the standard, let's do it.
I now have a file called:
locales/LC_MESSAGES/sv/ryf.mo

Don't RTFM me! I've read that page and unless you have a PhD in
physics and indept experience of Zope 3 is really doesn't make a lot
of sense. Plus, I've got your cookbook at home :)

So, should I use PTS or not??
"The default behaviour for choosing languages in Five is the one of
Zope 3: analyze the Accept-Language HTTP header and nothing more."
This is not good enough. When I send out email alerts to people in my
app, that's a wget script that kicks if off, not a Mozilla browser.
Besides, what if an Englishman is using a Swedish
internetcafe-computer when on holiday; in that case I want to allow
him to manually configure his user profile on my site.

I have no idea what this does or what I'm supposed to do with:
<adapter
    for="zope.publisher.interfaces.http.IHTTPRequest"
    provides="zope.i18n.interfaces.IUserPreferredLanguages"
    factory="Products.Five.i18n.PTSLanguages"
    />

Please tell me there's a function or something that works like this::

  def index_html(self):
       uid = self._getLoggedinUID()
       wants_lang = self._getUserPreference(uid, default='en')
       setCurrentLanguage(wants_lang)
       return _("I wish it was easier")

 def manage_setUserPreference(self, uid, lang):
      if lang in getAvailableLanguages():
          self._setUserPreference(uid, lang)

Where _getUserPreference() and _setUserPreference() is something I'm
expected to write for my app.
