	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 !

            <p>
            	Le Projet Autoblog a pour objectif de répliquer les articles d'un blog ou d'un site site web.<br/>
	            Si l'article source est supprimé, et même si le site d'origine disparaît, les articles restent lisibles sur l'autoblog. <br/>
	            L'objectif premier de ce projet est de lutter contre la censure et toute sorte de pression...
	        </p>
