How To Update Super Attributes In Magento?

Question

I am trying to figure out how to update a super attribute for a configurable product in Magento (specifically the upcharge price).

My initial investigation into this has lead me to believe that I will have to do something with the Configurable Type Instance of the product. Looking inside the Mage_Catalog_Model_Product_Type_Configurable class, I am not seeing anything that would have to do with price and it appears that this class does not have access to the debug function that most other objects in Magento have.

Can someone tell me how I would go about updating the upcharge prices of a super attribute?
