*
* Configuration:
* Add the following two lines to your .htconfig.php file:
*
* $a->config['piwik']['baseurl'] = 'www.example.com/piwik/';
* $a->config['piwik']['sideid'] = '1';
* $a->config['piwik']['optout'] = true; // set to false to disable
*
* Change the sideid to the ID that the Piwik tracker for your Friendika
* installation has. Alter the baseurl to fit your needs, don't care

* setting.
