|| When placed on an item, that item will have available slots into which other items, those with the Prop_ItemSlotFiller property, can be PUT using the PUT command. When this is done, the item with this property will gain the effect benefits of the other item in addition to its own.
The NUM parameter determines how many slots are available. The TYPE parameter must match the TYPE parameter from the Prop_ItemSlotFiller of the item being PUT. The REMOVEABLE property sets whether the items in the slots may be removed. See also Prop_ItemSlotFiller.
