* You can study them, modify them, use them in your own program - either

*
*
* This example tests most features of libirc. It can join the specific
* channel, welcoming all the people there, and react on some messages -
* 'help', 'quit', 'dcc chat', 'dcc send', 'ctcp'. Also it can reply to
* CTCP requests, receive DCC files and accept DCC chats.
*
* Features used:
* - nickname parsing;
* - handling 'channel' event to track the messages;
* - handling dcc and ctcp events;
* - using internal ctcp rely procedure;
* - generating channel messages;
* - handling dcc send and dcc chat events;
* - initiating dcc send and dcc chat.
