Lithium library that allows tracking of various in-app events with additional data.
Add a submodule to your li3 libraries:
git submodule add git@github.com:bruensicke/li3_activities.git libraries/li3_activities
and activate it in you app (config/bootstrap/libraries.php), of course:
Libraries::add('li3_activities');
Activity::track('sync_complete', $data);
