Analysis of information sources in references of the Wikipedia article "IrcII" in English language version.
The irc program is sometimes called ircII (IRC client, second edition) [...]
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".
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.
