- * restriction applied to their modification, redistribution, using and so on.
- * You can study them, modify them, use them in your own program - either
- * completely or partially. By using it you may give me some credits in your
- * program, but you don't have to.
- *
- *
- * This example 'guards' the channel against using abusive language. When
- * someone says a bad word, it takes some action against him/her, taking
- * in account the number of times the person uses it. The first time, it just
- * warns the person through a private message, the second time it warns him
- * publically in channel, and after the second time it will kicks the insolent
- * out of the channel.
- *
- * To keep it simple, this example reacts only on 'fuck' word, however
- * is is easy to add more.
- *
- * Features used:
- * - nickname parsing;
- * - handling 'channel' event to track the messages;
- * - handling 'nick' event to track nickname changes;
- * - generating channel and private messages, and kicking.
