-DEXTENDED_NUMERICS This option configures the server to send
extended numerics as well as parse them. This option should only
be used on networks that run ircu2.10.07 and above only.
--DFERGUSON_FLUSHER If you have a server with a lot of resources
-available this option will cause the server to attempt to flush
+-DFERGUSON_FLUSHER This causes your server to attempt to flush
it's internal buffers before dropping clients during a netbreak.
-Don't define this if you don't know, if you're not careful this
-can end up rebooting FreeBSD boxes.
+This option *may* panic your server - especially if your running
+on a unconfigured FreeBSD box. If you can define this we recommend

-DWALLOPS_OPER_ONLY Setting this option removes the ability for
clients that are not opered to see wallops messages.
+-DNOOPER Disallow the /oper command.

+There are a few to be used for debugging or other networks. These

+-DNICKLEN=15 This allows you do override the default nick length
+to 15 characters. If this has different values on different servers

+-DNO_THROTTLE This disables the throttling code. This is used for
+debugging *only*. It lets you connect up to 255 clients from one
+host with no time conciderations. If this is enabled on a
+production server I will personally drive your server into the
+ground. You have been warned.
Operating System and Kernel Requirements:
If you plan allowing more than 1000 clients on your server, you
