+ * Syntax: WEBIRC password client hostname ip
+ * Where password is a shared key, client is the name of the "client" and version (e.g. cgiirc), hostname
+ * is the resolved host of the client issuing the command and IP is the real IP of the client.
+ *
+ * How it works:
+ * To tie in with the rest of cgiirc module, and to avoid race conditions, /webirc is only processed locally
+ * and simply sets metadata on the user, which is later decoded on full connect to give something meaningful.
