/* Twitter Plugin for Hubzilla
*
* Author: Tobias Diekershoff
* tobias.diekershoff@gmx.net
*
* License:3-clause BSD license
*
* 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 Hubzilla 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.
*
* Activate the plugin from the plugins section of your admin panel. When you have
* done so, add your consumer key and consumer secret in the Plugin Features section
* of the admin page. A link to this section will appear on the sidebar of the admin page
* called 'twitter'.
*
* Alternatively: (old way - may not work any more)
* Add this key pair to your global .htconfig.php or use the admin panel.
*
* $a->config['twitter']['consumerkey'] = 'your consumer_key here';
* $a->config['twitter']['consumersecret'] = 'your consumer_secret here';
*
* Requirements: PHP5, curl [Slinky library]
