It was mentioned before: it is cleaner if you put the changed stuff in Botpack.cze and change
[Engine.Engine]
....
Language=cze
in UnrealTournament.ini.

Makes the variable localizable. The default value of the variable is read from a localization file when the class is loaded. Each subclass can have its own localized versions of the variable value. In Unreal Engine 1 and 2 and if the class is declared as PerObjectLocalized in Unreal Engine 3, each instance of the class can have its own set of localized variable values. This is useful for actors placed in a map.
