+The nospoof patch was adapted from the nospoof5 patch in use on Undernet
+servers.
+
+When a client connects to the server, they are sent a PING with a random
+number (please do not confuse this with a CTCP PING -- they're very
+different things). Until the client responds with a PONG and the correct
+random number, it is not registered with the server and cannot do
+anything.
+
+Please not that this _does_ break the RFC. However, it has been tested
+with most popular clients. The only client that appears to have problems
+is Homer.
+
+To cater for possibly broken clients, a message is also sent to clients
+on connect of the form:
+
+*** If your client freezes here, type /QUOTE PONG 12345678 or /PONG 12345678
+
+To cater for this, it is a good idea to increase the allowed timeout on
+connections since the user might have to manually PONG the server with
+the ugly number.
+
+If the client PONGs with the wrong number, another message is sent to
+the client directing the user what to type. In addition, if the
+connection does end up timing out due to no PONG, a message is sent to
+the user explainging the client may not be compatible, and lists where
+compatible clients for all the major platforms can be found.
+
+The random number sequence is based on an md5 series. I didn't write it.
+Someone else did. It's included because many have a dud random() in their
+libc (this applies to more people than you think). It is seeded on a
+#define value in config.h - YOU MUST CHANGE THIS FROM THE DEFAULT OR YOU
+CAN STILL BE SPOOFED. If you still find that you get spoofed, try
+changing this value again and recompiling.
