-/**
- * Name: Facebook Connector
- * Version: 1.0
- * Author: Mike Macgirvin <http://macgirvin.com/profile/mike>

-/**
- * Installing the Friendika/Facebook connector
- *
- * 1. register an API key for your site from developer.facebook.com
- *   a. We'd be very happy if you include "Friendika" in the application name
- *      to increase name recognition. The Friendika icons are also present
- *      in the images directory and may be uploaded as a Facebook app icon.
- *      Use images/friendika-16.jpg for the Icon and images/friendika-128.jpg for the Logo.
- *   b. The url should be your site URL with a trailing slash.
- *      You may use http://portal.friendika.com/privacy as the privacy policy
- *      URL unless your site has different requirements, and 
- *      http://portal.friendika.com as the Terms of Service URL unless
- *      you have different requirements. (Friendika is a software application
- *      and does not require Terms of Service, though your installation of it might).
- *   c. Set the following values in your .htconfig.php file
- *         $a->config['facebook']['appid'] = 'xxxxxxxxxxx';
- *         $a->config['facebook']['appsecret'] = 'xxxxxxxxxxxxxxx';
- *      Replace with the settings Facebook gives you.
- *   d. Navigate to Set Web->Site URL & Domain -> Website Settings.  Set 
- *      Site URL to yoursubdomain.yourdomain.com. Set Site Domain to your 
- *      yourdomain.com.
- * 2. Enable the facebook plugin by including it in .htconfig.php - e.g. 
- *     $a->config['system']['addon'] = 'plugin1,plugin2,facebook';
- * 3. Visit the Facebook Settings section of the "Settings->Plugin Settings" page.
- *    and click 'Install Facebook Connector'.
- * 4. This will ask you to login to Facebook and grant permission to the 
- *    plugin to do its stuff. Allow it to do so. 
- * 5. You're done. To turn it off visit the Plugin Settings page again and
- *    'Remove Facebook posting'.
- *
- * Vidoes and embeds will not be posted if there is no other content. Links 
- * and images will be converted to a format suitable for the Facebook API and 
- * long posts truncated - with a link to view the full post. 
- *
- * Facebook contacts will not be able to view private photos, as they are not able to
- * authenticate to your site to establish identity. We will address this 
- * in a future release.
