	# THIS IS PROOF-OF-CONCEPT CODE
	# ALL THE USUAL CAVEATS APPLY.
	# NO. REALLY.

	# This is a dumb sample script to fetch all the instagram photos
	# belonging to a user and then upload them to their flickr account.
	# It assumes that you are using Flamework (or a similar derivative).
	# Also that you've got valid auth tokens for both Flickr and Instagram
	# which are left out of this example and as an exercise to the user.
	# Really, it's just meant to be a reference implementation and not
	# anything you'd actually use. Note: There is no error checking, handling
	# or reporting. It might still have bugs. (20120227/straup)
