There are several sources that point to pages of the old pyjs.org website (included in e.g. https://www.google.com/search?q=link:pyjs.org). We should figure those out and provide clean redirects to the appropriate pages of our current website.
Links with hash-notation (e.g. http://pyjs.org#Overview) will be a challenge for the webserver. We should decide if we deal with those at all if that's tricky. Such links would land on pyjs.org's home page - we won't lose users -, so we could limit our acting on Error404s that are raised.
