   4  * This module still needs a lot of work, but is functional today.
   5  * Please review this section if you upgrade because things will change.
   6  * If you have issues upgrading, remove facebook from the addon list,
   7  * view a page on your site, then add it back to the list. This will reset
   8  * all of the plugin 'hooks'.
   9  *
  10  * 1. register an API key for your site from developer.facebook.com
  11  *   a. We'd be very happy if you include "Friendika" in the application name
  12  *      to increase name recognition. The Friendika icons are also present
  13  *      in the images directory and may be uploaded as a Facebook app icon.
  14  *      Use images/ff-16.jpg for the Icon and images/ff-128.jpg for the Logo.
  15  *   b. The url should be your site URL with a trailing slash.
  16  *      You may use http://portal.friendika.com/privacy as the privacy policy
  17  *      URL unless your site has different requirements, and
  18  *      http://portal.friendika.com as the Terms of Service URL unless
  19  *      you have different requirements. (Friendika is a software application
  20  *      and does not require Terms of Service, though your installation of it might).
  21  *   c. Set the following values in your .htconfig.php file
  22  *         $a->config['facebook']['appid'] = 'xxxxxxxxxxx';
  23  *         $a->config['facebook']['appsecret'] = 'xxxxxxxxxxxxxxx';
  24  *      Replace with the settings Facebook gives you.
  25  * 2. Enable the facebook plugin by including it in .htconfig.php - e.g.
  26  *     $a->config['system']['addon'] = 'plugin1,plugin2,facebook';
  27  * 3. Visit the Facebook Settings from "Settings->Plugin Settings" page.
  28  *    and click 'Install Facebook Connector'.
  29  * 4. This will ask you to login to Facebook and grant permission to the
  30  *    plugin to do its stuff. Allow it to do so.
  31  * 5. You're done. To turn it off visit your site's /facebook page again and
  32  *    'Remove Facebook posting'.
  33  *
  34  * Turn logging on (see the github Friendika wiki page 'Settings') and
  35  * repeat these steps if you have trouble.
  36  * Vidoes and embeds will not be posted if there is no other content. Links
  37  * and images will be converted to text and long posts truncated - with a link
  38  * to view the full post. Posts with permission settings and comments will
  39  * not be posted to Facebook.
