Epoch Books Class Names

[Thug]

Can someone tell me where to look for the class names of the Preformance books in Epoch. i.e.  ORP (off road preformance).. We have a Overpoch Origins Taviana and it uses the books to build the Origins houses. I need to add them to the traders.

	class ItemORP {type = "trade_items";buy[] = {1,"ItemGoldBar10oz"};sell[] = {5,"ItemGoldBar"};};
	class ItemTNK {type = "trade_items";buy[] = {1,"ItemGoldBar10oz"};sell[] = {5,"ItemGoldBar"};};
	class ItemLRK {type = "trade_items";buy[] = {1,"ItemGoldBar10oz"};sell[] = {5,"ItemGoldBar"};};
	class ItemAVE {type = "trade_items";buy[] = {1,"ItemGoldBar10oz"};sell[] = {5,"ItemGoldBar"};};
