 -- The script parameter can be used to configure the energy

--- key is a word and each value is non-negative integer.
+-- key is a word and each value is an negative integer between 0 and 4294967295.
 --
 -- Possible keys:
 --- initialenergy: Amount of energy that each team starts with (default: 550)
 --- energyperround: Amount of energy that each team gets per round (default: 50)
---- maxenergy: Maximum amount of energy each team can hold (default: 1000)
+--- maxenergy: Maximum amount of energy each team can hold (default: 1000).
 
 -- Example: “initialenergy=750, maxenergy=2000” starts thee game with 750 energy
 -- and sets the maximum energy to 2000
