Events (and event subscriptions) are a major concept for loose
integration of independent components.

Zope3 supports events and event subscriptions. However, its
subscriptions are global. Many (local) services are interested in
events generated in a specific subsite. A prominent example are
catalogs that catalog objects in a subsite.

"localevent" is a Zope2 product. It provides a (persistent and local)
local_event_subscription tool (in the sense of CMF tools). Other tools
can use it to subscribe for (Zope3) events originating in the subsite
rooted in the parent of the local_event_subscription instance.
