How do I use the bulkloader to upload keys? 
I have to upload an entity into the GAE datastore with its original key. In the documentation, and in some questions here, I see how to [create a key][1], [upload a keyname based on a string][2], and [create a foreign key][3], but not just do a 1:1 upload. 

How is this possible?
