Shortly after we released this code, another module showed up http://drupal.org/project/piwik that does very similar things. We approached and agreed with hass that we will merge these two projects to combine our efforts and not end up with multiple modules. Please use http://drupal.org/project/piwik as this is where active development will be done.
Basically the module provides two functions,
- It allows you to track visitors to your site in the same way as you do with Google Analytics Module.
- It gives you access to the Piwik reports from within Drupal.
Not ready for production use.
