* License: 3-clause BSD license
*
* Configuration:
* Use the administration panel to configure the Piwik tracking addon, or
* in case you don't use this add the following lines to your .htconfig.php
* file:
*
* $a->config['piwik']['baseurl'] = 'www.example.com/piwik/';
* $a->config['piwik']['siteid'] = '1';
* $a->config['piwik']['optout'] = true; // set to false to disable
* $a->config['piwik']['async'] = false; // set to true to enable
*
* Change the siteid to the ID that the Piwik tracker for your Friendica
* installation has. Alter the baseurl to fit your needs, don't care
* about http/https but beware to put the trailing / at the end of your
* setting.
