+"""
+A plugin that helps you identify the times of a conversation.  For example
+if you disable the timestamps, and remove the join/quit notifications in a
+MUC, you can’t really distinguish when a conversation stopped and when a new
+one started, because you don’t have a visual separation between the two.
+
+This plugin displays a message in the conversation indicating the time that
+passed between two messages, if the time is bigger than X minutes
+(configurable, of course. Default is 15 minutes). This way you know how many time elapsed between
+them, letting you understand more easily what is going on without any visual
+clutter.
