+# IRC - Internet Relay Chat - RFC 1459
+# Pattern quality: good veryfast
+#
+# Usually runs on port 6666 or 6667
+# Note that chat traffic runs on these ports, but IRC-DCC traffic (which
+# can use much more bandwidth) uses a dynamically assigned port, so you 
+# must have the IRC connection tracking module in your kernel to classify
+# this.
+#
+# This pattern has been tested and is believed to work well.  If it does not
+# work for you, or you believe it could be improved, please post to

+# First thing that happens is that the client sends NICK and USER, in 
+# either order.  This allows MIRC color codes (\x02-\x0d instead of
+# \x09-\x0d).
