This module implements an event handler that CT uses to +%%% handle status and progress notifications during test runs. +%%% The notifications are handled locally (per node) and passed +%%% on to ct_master when CT runs in distributed mode. This +%%% module may be used as a template for other event handlers +%%% that can be plugged in to handle local logging and reporting.
