Rotation System
Set the xp_rotation "rotation.txt" variable to the file where your rotation is.
Server admins will find /rcon rotate useful. The syntax is also alot like the Configuration System.
The following example should be self explaining.

Example:

// this will be executed before each map
timelimit: 20
fraglimit: 25
g_gametype: 0

q3dm1 {
fraglimit: 50
}
q3dm2

// as you see additional settings like { ... } are optional
q3dm3

// lets have a ctf game with 'xp.cfg'
q3ctf1 {
g_gametype: 4
timelimit: 15
capturelimit: 10
/load conf/xp
}

// this will be ffa! remember the "g_gametype: 0"
q3ctf4

...i have diff way to set it : in server config.(including rotation)
