Here is a more in-depth explanation into some of the features
that can change the server. 

1) config/config.h defines :

	AUTOMOTD - Use this if you're not going to run the update daemon.
		This will check you .motd and rebuild it every once in a 
		while. Don't use both AUTOMOTD and the update daemon.

	CHAIN_REACTION - This will not give credit for chain-reaction and
		will also report how a player died.

	CHECKMESG - log god or all messages. You should use LOGALL and
		LOGGOD parameters in .sysdef with these.

	ERIKPLAGUE - Eric Mehlhaff's planet plague code that was used for
		SINL 93.

	FEATURES - This is for client/server communication. You can specify
		options in the .features file that some servers may have.

	INL_POP - This is the planet pop code used in SINL 93.

	NEED_EXIT - Some systems need exit to be defined in socket.c

	NO_PLANET_PLAGUE - Don't allow planet plaguing. Don't use this with
		ERIKPLAGUE.

	PING - Allow ping stats support. This may increase the network load a
		little.

	RSA - Use RSA verification. Some method of verification is recommended.
		RSA is the most accepted method now.

	SHOW_RSA - Display some messages like failed RSA verification message
		and type of client on entry of player.

	RESETGALAXY - Every time a conquer occurs reset the galaxy.

	SELF_RESET - galaxy will reset if daemon dies.

	SHORT_PACKETS - Use short packets code. This may increase the load on
		the server but will decrease the network load by up to %50.

	SHORT_THRESHOLD - More support for Short packets. If you define
		SHORT_PACKETS it's a good idea to use this also.

	SURRENDER_SHORT - Cut the surrender time in half when the genocide
		counter starts.

	SPEEDUP - Some misc. improvements to make the daemon faster.

	TWO_RACE - Conquer only a 1/4 of the galaxy for the galaxy to reset.

	SENDFLAGS - Print flags used in the compile on the MOTD.

	CHECK_ENV - Check the environment variable NTSERV_PATH for the
		location of system files.

	GPPRINT - Print the path that is being used to find the system files.

	ONCHECK - trekon (xbiff) support for checking if the logins.

	NEWMASK - Use a newer tournament mask function that is less rigid
		than older version. Doesn't take preferences into account.

	RCD - Support Receiver variable distresses. (Saves on a lot of network
		traffic).

	FLAT_BONUS - 5x bonus for killing last army on a planet 

	BASEPRACTICE - Base training server. (Need special robots, see 
		README.basep).

	NEW_CREDIT - give 1 planet for destroying, two planets for taking.

	SBFUEL_FIX - fix starbase re-fueling 

	NEW_ETEMP - Wreck's etemp fix 

	DOGFIGHT - .sysdef interface for dogfight robot 

	VOTING - allow voting mode

        ALLOW_EJECT     - define to allow players to eject others (only when
			  VOTING is defined).

        NO_BRUTALITY    - disallow fighting between waiting players in the 
			  dogfighting mode (only when DOGFIGHT is defined).

	ROBOT_OBSERVER_OFFSET	- define to ensure that the moderation robot
			  is always in slot g.

	SB_RAPID_COOLDOWN	- allows for twice the normal rate of weapon
				  cool down; useful on base-practice.

	ALLOW_PRACTICE_ROBOT_SB	- allows practice robots to be refit into
				  starbases if defined.

	In addition ship characteristics can be changed. The list of
	characteristics that can be changed are:         
          TURNS, ACCS, TORPDAMAGE, PHASERDAMAGE, PHASERFUSE, PLASMADAMAGE, 
          TORPSPEED, TORPFUSE, TORPTURNS, PLASMASPEED, PLASMAFUSE, PLAMSATURNS, 
          MAXSPEED, REPAIR, MAXFUEL, TORPCOST, PLASMACOST, PHASERCOST, 
          DETCOST, WARPCOST, CLOAKCOST, RECHARGE, ACCINT, DECINT, MAXSHIELD, 
          MAXDAMAGE, MAXEGNTEMP, MAXWPNTEMP, EGNCOOLRATE, WPNCOOLRATE, 
          MAXARMIES, WIDTH, HEIGHT, TYPE, MASS, TRACTSTR, TRACTRNG.

	  To set ship characteristics you need to do something like the
	  following: 

		SHIP=1
		BB PHASERCOST 945
		AS TORPCOST 210
		!       MaxWpnTemp should ONLY be defined when non-chaos mode.
		SB MAXWPNTEMP 1500
		END

	  Unless SHIP is 1 the stats between SHIP and END will not be read in.
	  This example sets the NEWSHIP defines found at some servers. A '!'
	  is a comment.




3) .time file.

	The time file is an array field that is 7 by 24. Each line is for the
	days of the week and each character in the line is for the hours.
	Line 0 is Sun. Line 6 is Sat. Char. 0 is 12am and char 23 is 11pm.

	Allowable characters are:

		X - Non-playable hours. The server is down.

		C - Clue hour. The server is up and checking for clue.

		Anything else is interpreted as playable.

4) .features file.

	The .features file specifies the features specific to a client that
	are allowed at a server. There are two formats for a line in the
	features file. The client type is gotten from the RSA client type
	field.

		1) <Client Type>: <Features>
		   EX:
			BerkRick Moo: SMARTMACRO NEWMACRO

		   This method doesn't check for the version of the client.
		   It is assumed that every version of this client will have
		   these features.

		2) <Client Type>*confirm:<Version>: <Features>
		   EX:
			BerkRick Moo*confirm:2.00.15: WHY_DEAD

		   This method checks the version sent by the client to see if
		   the client is new enough to have this feature. The client
		   has to have a version >= to the version specified to have
		   the server send the message to the client. The Version field
		   in is in the format of: Version:PatchLevel.

5) .banned file, clue-bypass file.

	These both use a similar format. The .banned file lists players that are
	banned from the server. The .clue-bypass lists players that don't need
	to go through clue checking.

	Each line in these files should follow the format:

		<login>@<domain>
	The domain field can contain the total domain such as 
	guzzler.ecst.csuchico.edu or can contain "*"s for all names such as
	*.ecst.csuchico.edu would include all machines in the .ecst.csuchico.edu
	domain.

Under Solaris 2.5.1 the wildcard "*" does not work. If wish to ban
all login attempts from rpi.edu, I must have something like this in my
.banned file:

leemy@rpi.edu

If I do a leemy@*.rpi.edu the ban does not work. If the "*" wildcard
method does not work try this way.

6) Robot configuration

	The newbie and pre-t robots accept commands from players by
	default.  To prevent potential abuse this feature may be
	deactivated by editing robotd/defs.h and changing the line:

	#undef BOTS_IGNORE_COMMANDS

	to

	#define BOTS_IGNORE_COMMANDS

	This change will require the bots to be re-compiled and
	reinstalled.
