    Instructions:
     (by default, autoblog creation is allowed: you can set this to "FALSE" in config.php)
     (by default, Cross-Site Autoblog Farming [XSAF] imports a few autoblogs from https://github.com/mitsukarenai/xsaf-bootstrap/blob/master/3.json you can uncomment and add xsafimports in xsaf3.php (jump at end of file) )
     (by default, database and media transfer via XSAF is allowed)

    - upload all files on your server (PHP 5.3+ required)
    - PROFIT!

Si l'article source est supprimé, et même si le site d'origine disparaît, les articles restent lisibles sur l'autoblog. L'objectif premier de ce projet est de lutter contre la censure et toute sorte de pression…</p>
