ScrollZ

Enhanced ircII client that supports scripts, colors, and more

ScrollZ is an IRC client based on ircII with many enhancements (colors, userlists, enhanced scripting, and more). The main difference from other clients is that it implements many useful features that you would normally find in a script, thus making it faster than such scripts paired up with ircII. It also has many unique features, such as three-line status bars, CDCC (which has reget/resend ability), and its environment is highly customizable.
