LunaScript is a fantastic Spanish script for BitchX. It has lots of interesting features, including 3 windows (main, status, and privates), a sound system, clones detection, MP3 reproduction, favourite channels, addons for different IRC networks (auto-identification), and lots more.
Ofnibot seeks to reimplement a subset of the functionality provided by the popular Infobot IRC information bot. It learns from chat conversations and answers questions from users based on its knowledge. Ofnibot is written in Perl and uses the POE IRC modules for IRC communication. Its database files are compatible with Infobot database files and Ofnibot supports a large subset of Infobot commands. On the other hand, Ofnibot was programmed from the ground up to be small and compact. Consequently, it does not include most of the "extras" provided by other IRC information bots.
