+ * All the communication with the IRC network is based on events. Generally

+ * or by the IRC server itself. "Someone sends you a message", "Someone
+ * has joined the channel", "Someone has quits IRC" - all these messages
+ * are events.
+ *
+ * Every event has its own event handler, which is called when the 
+ * appropriate event is received. You don't have to define all the event
+ * handlers; define only the handlers for the events you need to intercept.
+ * 
+ * Most event callbacks are the types of ::irc_event_callback_t. There are 
+ * also events, which generate ::irc_eventcode_callback_t, 
+ * ::irc_event_dcc_chat_t and ::irc_event_dcc_send_t callbacks.
