Event Handling Framework - What is a typical use case?

Hi community,

I just have seen this new blog article regarding the Event Handling Framework.

 Event Handling Framework Overview and Installation 

I think it´s a useful new feature, I just have one problem. Which task can I solve with this framework? What is a typical use case where I can use this feature?

Quote:
Every time the appropriate system event occurs, an EHF Item Event is generated and added to the publishing events queue.

So the framework is used to automatically publish PDFs (MPP/TechDocs/OC)? Or does it do something else?

Great feature, but I really don´t get it!Joy
