From [http://en.wikipedia.org/ Wikipedia] (under GFDL):

• Some travellers come to a village, carrying nothing more than an empty pot. Upon their arrival the villagers are unwilling to share any of their food stores with the hungry travellers. The travellers fill the pot with water, drop a large stone in it, and place it over a fire in the village square. One of the villagers becomes curious and asks what they are doing. The travellers answer that they are making "stone soup", which tastes wonderful, although it still needs a little bit of garnish to improve the flavor, which they are missing. The villager doesn't mind parting with just a little bit to help them out, so it gets added to the soup. Another villager walks by, inquiring about the pot, and the travellers again mention their stone soup which hasn't reached its full potential yet. The villager hands them a little bit of seasoning to help them out. More and more villagers walk by, all adding another ingredient. Finally, a delicious and nourishing pot of soup is enjoyed by all.

To come: Apply Stone Soup to HCOOP. (It rhymes!)
