<?php
+/* Twitter Plugin for Friendika
+ *
+ * Author: Tobias Diekershoff
+ * tobias.diekershoff@gmx.net
+ *
+ * License:3-clause BSD license (same as Friendika)
+ *
+ * Configuration:
+ * To use this plugin you need a OAuth Consumer key pair (key & secret)
+ * you can get it from Twitter at https://twitter.com/apps
+ *
+ * Register your Friendika site as "Client" application with "Read & Write" access
+ * we do not need "Twitter as login". When you've registered the app you get the
+ * OAuth Consumer key and secret pair for your application/site.
+ *
+ * Add this key pair to your global .htconfig.php
+ *
+ * $a->config['twitter']['consumerkey'] = 'your consumer_key here';
+ * $a->config['twitter']['consumersecret'] = 'your consumer_secret here';
+ *
+ * To activate the plugin itself add it to the $a->config['system']['addon']
+ * setting. After this, your user can configure their Twitter account settings
+ * from "Settings -> Plugin Settings".
+ *
+ * Documentation: http://diekershoff.homeunix.net/redmine/wiki/friendikaplugin/Twitter_Plugin
+ */
+
+/* __TODO__
+ *
+ * - deletion of the OAuth credentials does not work
+ * - include short links to the original posting if possible
+ * - what about multimedia content?
+ * so far we just strip HTML tags from the message
+ * - after entering the PIN reload page propperly
