        # in the currency of the company owning the product. OpenERP
        # read the average price from price_get method, which
        # convert the price to company currency.
        # So, in case you have:
        #   Rate from CHF to EUR 1.2
        #   Company in CHF
        #   Price type in EUR
        #   Product AVG price = 10.-
        #   Reception new product with cost 15.- (in CHF in price_unit
        #   of moves)
        #   The price_get will return the current average price in CHF of 12.-
        #   The price computed will be =(12 * qty + 15 * qty') / (qty + qty')
        #   in CHF. The new cost will be store as is in the procuct
        #   standard_price instead of converting the result in EUR
