Description:
KDE-based next generation IRC client with module support
A highly configurable graphical IRC client with an MDI interface, built-in scripting language, support for IRC DCC, drag & drop file browsing, and much more. KVIrc uses the KDE widget set, can be extended using its own scripting language, integrates with KDE, and supports custom plugins. . If you're looking for a simple and plain IRC client, KVIrc is probably the wrong choice as it is rather big. But if you want a highly customizable client you won't regret the installation.
