ircII (IRC Client, Second Edition) ircII is a full screen, curses-based interface to Internet Relay Chat. It gives full access to all of the normal IRC functions, plus a variety of additional options. ircII is the oldest IRC client still maintained. By default, this SlackBuild sets the default IRC server to "SSLIRC/chat.freenode.org:6697". This only applies with ircII is run without a server argument on the command line. You can change the default server by setting the DEFSRV environment variable to the host:port (with optional SSLIRC/ prefix for a secure connection), or compile without a default server with DEFSRV=none.
