DreamBot is an experimental IRC bot totally written in Perl. Its main features include a totally dynamic user and channel list (no need to deal with text files), a learning ability that's similiar to infobot, built-in seen and topten talkers support, notes/memos, pasting of Freshmeat and Slashdot news, and Babelfish (Altavista) translation. DreamBot doesn't require any extra Perl modules.
EPIC4 is a new direction in ircII development. It was originally built upon the ircII-2.6 client and has maintained faithfulness to remain current up to the 2.8.2 release. EPIC is somewhat larger than the stock client (24%), but that is mostly because of the multitude of new features, the dual ANSI/K&R compliant function headers, and the large amount of re-written code in an attempt to make ircii faster, more efficient, and more powerful.
