===aifill - Limited number of AI players===
If set to a positive value, then AI players will be automatically
created or removed to keep the total number of players at this amount.
As more players join, these AI players will be replaced. When set to
zero, all AI players will be removed.
Level: Vital.Category: Internal.
Minimum: 0, Default: 5, Maximum: 500
Value set to 6
----
===airliftingstyle - Airlifting style===
This setting affects airlifting units between cities. It can be a set
of the following values:
- "Allows units to be airlifted from allied cities" (FROM_ALLIES).
- "Allows units to be airlifted to allied cities" (TO_ALLIES).
- "Unlimited units from source city" (SRC_UNLIMITED): airlifting from
a city doesn't reduce the airlifted counter. It depends on the ruleset
whether this is possible even with zero airlift capacity.
- "Unlimited units to destination city" (DEST_UNLIMITED): airlifting
to a city doesn't reduce the airlifted counter. It depends on the
ruleset whether this is possible even with zero airlift capacity.

----
===allowtake - Players that users are allowed to take===
This should be a string of characters, each of which specifies a type
or status of a civilization (player).
Clients will only be permitted to take or observe those players which
match one of the specified letters. This only affects future uses of
the "take" or "observe" commands; it is not retroactive. The
characters and their meanings are:
 o,O = Global observer
 b = Barbarian players
 d = Dead players
 a,A = AI players
 h,H = Human players
The first description on this list which matches a player is the one
which applies. Thus 'd' does not include dead barbarians, 'a' does not
include dead AI players, and so on. Upper case letters apply before
the game has started, lower case letters afterwards.
Each character above may be followed by one of the following numbers
to allow or restrict the manner of connection:
(none) = Controller allowed, observers allowed, can displace
connections. (Displacing a connection means that you may take over a
player, even when another user already controls that player.)
 1 = Controller allowed, observers allowed, can't displace
connections;
 2 = Controller allowed, no observers allowed, can displace
connections;
 3 = Controller allowed, no observers allowed, can't displace
connections;
 4 = No controller allowed, observers allowed

===mgr_distance - Maximum distance citizens may migrate===
This setting controls how far citizens may look for a suitable
migration destination when deciding which city to migrate to. The
value is added to the candidate target city's radius and compared to
the distance between the two cities. If the distance is lower or
equal, migration is possible. (So with a setting of 0, citizens will

===migration - Whether to enable citizen migration===
This is the master setting that controls whether citizen migration is
active in the game. If enabled, citizens may automatically move from
less desirable cities to more desirable ones. The "desirability" of a
given city is calculated from a number of factors. In general larger
cities with more income and improvements will be preferred. Citizens

disbanding a city. A number of other settings control how migration
behaves:
 'mgr_turninterval' - How often citizens try to migrate.

individual players in order from a list defined by the ruleset.
- "Per-player, random" (PLR_RANDOM): colors are assigned to individual
players randomly from the set defined by the ruleset.

Default: "freeciv"
----
===savepalace - Rebuild palace whenever capital is conquered===
If this is turned on, when the capital is conquered the palace is

===startpos - Method used to choose start positions===
The method used to choose where each player's initial units start on
the map. (For scenarios which include pre-set start positions, this
setting is ignored.)

depend on the map generator chosen. See the 'generator' setting.
- "One player per continent" (SINGLE): one player is placed on each of
a set of continents of approximately equivalent value (if possible).

except that two players will be placed on each continent, with three
on the 'best' continent if there is an odd number of players.
- "All players on a single continent" (ALL): all players will start on
the 'best' available continent.
- "Depending on size of continents" (VARIABLE): players will be placed
on the 'best' available continents such that, as far as possible, the
number of players on each continent is proportional to its value.
If the server cannot satisfy the requested setting due to there being
too many players for continents, it may fall back to one of the
others. (However, map generators try to create the right number of
continents for the choice of this 'startpos' setting and the number of
players, so this is unlikely to occur.)
