XChat is an IRC client that operates on X11 windowing system requiring full X11 environment like XDarwin. It is built on GTK+ and enables chatting on IRC channels seamlessly.
If you have XDarwin installed or a similar full X11 windowing environment, then XChat will function just as smoothly as you'd expect. But without it, you'll need to install it first in order to use the software effectively.
Overall, XChat is a great option for anyone in need of a powerful IRC client, as long as you're already using an X11 windowing system. Its interface is simple yet effective, allowing you to focus on the important aspects of your work without getting bogged down by unnecessary details.
