Thanks for your work on the Eventful plugin. I've been starting to use it pretty heavily on an internal application at IBM. I've made a few fixes and updates including to the readme. Hope this helps keep the code up to date and useful for others.
Fixes the App:import for the app_****_events.php files. Adds support for
importing the app_shell_events.php file.
Fix to the "Class 'Empty' not found" problem.
Move shell task code into its proper location under the vendors folder
so that CakePHP will recognize and find the task. Added usage
Add the dispatch method, which aliases dispatchEvent method, to the
model behavior for consistency and to correct a problem in the readme.
Updating readme with additional examples and explanations about usage.
