3 * Name: Facebook Connector
5 * Author: Mike Macgirvin <http://macgirvin.com/profile/mike>
6 * Tobias Hößl <https://github.com/CatoTH/>
10 * Installing the Friendica/Facebook connector
12 * Detailed instructions how to use this plugin can be found at
13 * https://github.com/friendica/friendica/wiki/How-to:-Friendica%E2%80%99s-Facebook-connector
15 * Vidoes and embeds will not be posted if there is no other content. Links
16 * and images will be converted to a format suitable for the Facebook API and
17 * long posts truncated - with a link to view the full post.
19 * Facebook contacts will not be able to view private photos, as they are not able to
20 * authenticate to your site to establish identity. We will address this
21 * in a future release.
25 * - Implement a method for the administrator to delete all configuration data the plugin has created,
26 * e.g. the app_access_token
