This namespace contains all classes, that are needed for extended use of an irc connection. The [IrcConnection] class can be used to create a fully managed irc connection with all features of the IrcSharp.Extended namespace. But you can use only parts of this namespace too. Then you only need an [IrcSharp.IrcClient] instance what is used as the underlying connection. So if you only want to know in what channels you are, this can be easily done by iniialising a connection to an irc server by the IrcSharp.IrcClient class and hand over this instance to the constructor of the [ChannelManager.ChannelManager] constructor, to get a ChannelManager instance, that tracks the channels on this connection. This allows you to take fully control of what should be done by the IrcSharp library, and what you wan't do your self.
