+ \page bot Bot example
+
+ The example presents a simple IRC bot that can handle half a dozen commands.
+ This article focuses on handling messages, and parsing and sending commands.
+ See the \ref minimal "Minimal example" for basics on setting up an IRC
+ connection.
+
+ \image html bot.png "The bot example in action"
+
+ The bot uses IrcCommandParser for parsing commands from messages received
+ from other clients. In order to take it in use, the desired commands must
+ be first introduced.
+
+ \snippet bot/ircbot.cpp commands
+
+ Some of the commands are context sensitive. Thus, the parser must know
+ the list of channels the bot is on. This is easily achieved with help of
+ IrcBufferModel.
+
+ \snippet bot/ircbot.cpp channels
+
+ Furthermore, the current target of the parser is later updated whenever
+ messages are received and parsed for commands.
+
+ In order for the bot to be able to process private and channel
+ messages, it connects to the \ref IrcConnection::messageReceived()
+ "IrcConnection::privateMessageReceived()" signal.
+
+ \snippet bot/ircbot.cpp messages
+
+ The current target of the parser, and command triggers are chosen depending
+ on whether the received message is a channel or private message. The next
+ snippet illustrates how the logic of the bot has been implemented using
+ IrcCommandParser.
+
+ \snippet bot/ircbot.cpp receive
+
+ Notice how the help command is implemented as a "custom" command. This is
+ because it does not correspond to any actual IRC command, but we want the
+ bot to reply with a help message instead of performing an actual command.
+
+ Finally, the last snippet shows the bot in action!
