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.
