“IRC clients primarily for the Unix shell”. irchelp.org(2004年5月9日).2010年11月10日閲覧。“Note on the pronunciation of ircII: Some of us like to call it "eye-are-see-two". However, the other main variant, "irk-two" is probably historically more accurate. It's also commonly called "urk-ee" which is most definitely wrong. Feel free to disagree with us, we're not going to argue the point to death. What's pretty certain is that it is "two" and not "ee".”

Rollo, Troy.“A description of the DCC protocol”. irchelp.org.2010年11月10日閲覧。“The first comment I should make is that the DCC protocol was never designed to be portable to clients other than IRCII. As such I take no responsibility for it being difficult to implement for other clients.”
