A refinement:  use os.path.join(), rather than just join().  It's 
smarter about adding the right kind of slash between the nodes, if 
needed.  Currently, if you leave off the trailing slash (from 
"directory"), you'll end up with the files being one level up, and the 
individual files having a string prepended.
