9To load all entities in this library load the events_loader.lgt utility
10file:

14The objects event_registry, before_event_registry, and after_event_registry
15implement convenient predicates for registering before and after events.
16
17The protocol event_handlersp declares the two basic event handler predicates
18(before/3 and after/3). You will need to refer this protocol in your objects
19if you want to use the super control structure (^^/1) with these predicates.
20
21The monitor object implements more sophisticated event handling predicates.
22
23Some of the objects assume that the chosen Prolog compiler defines the
24usual sort/2 built-in predicate.
