KildClient is a powerful MUD client with a built-in Perl interpreter
KildClient is a mud client using the GTK toolkit. Its main feature is the support of Perl scripting. Other standard features of mud clients (triggers, gags, macros, etc.) are also supported.
KiTTY++ is an even more feature-rich fork of PuTTY, the free Windows SSH/Telnet client. This branch is a forward-port of old KiTTY features and a lote more onto current PuTTY 0.85 — so you get old and new KiTTY's extras on top of a modern, security-patched PuTTY core.
