Server Configuration Modes.

C      - Command Line Config 

         This option allows the ircd.conf file to be specified on 
         command line when the IRCd is started. 

d      - Do ID
         This option checks identd. If this is undefined, the IRCd will
         never check identd, regardless of @'s in I:lines. You must still use @'s
         in your I: lines to get the IRCd to do ident lookups.
D      - Debug Mode

         DEBUGMODE is used mostly for internal development. On a working server, 
         you probably won't ever see this.
H      - Hub

         This option enables server<-->server routing. If your server is running 
         as a HUB Server then define this. A HUB Server has many servers that connect 
         to it at the same time; a leaf just has one server (typically the uplink) 
         connected to it. 

i      - Show Invisible Lusers 
         This option shows invisible clients in /LUSERS. This will show the correct
         invisible count for anyone who does /LUSERS on your server. On a large net,
         this doesn't mean much, but on a small net it might be an advantage to undefine it.  
I      - No Default Invisible

         If this option is used, clients are not set +i by default. When defined, your
         users will not automatically be attributed with user mode "i" (invisible). 
         Invisibility means nicks don't show up in /WHO or /NAMES unless they are on 
         the same channel as you.
p      - Crypt Oper Password 

         This option allows the use of crypted oper passwords in the ircd.conf. 

u      - ircII Kludge 

         This option sends an extra NOTICE in the beginning of client connection to 
         keep ircII happy. 

Y      - Use Syslog 

         This option logs errors and such to the System Log. This sends "vital" messages 
         about server through syslog. Only system errors and events critical to the 
         server are logged. 


NOTE: These are the options to be found using the /VERSION server command.
