10 /* StatusNet Plugin for Friendica
12 * Author: Tobias Diekershoff
13 * tobias.diekershoff@gmx.net
15 * License:3-clause BSD license
18 * To activate the plugin itself add it to the $a->config['system']['addon']
19 * setting. After this, your user can configure their Twitter account settings
20 * from "Settings -> Plugin Settings".
22 * Requirements: PHP5, curl [Slinky library]
24 * Documentation: http://diekershoff.homeunix.net/redmine/wiki/friendikaplugin/StatusNet_Plugin
28 * We have to alter the TwitterOAuth class a little bit to work with any StatusNet
29 * installation abroad. Basically it's only make the API path variable and be happy.
31 * Thank you guys for the Twitter compatible API!
