# This IPython Notebook magic writes the content of the cell to a specified .py 
# file before executing it. An identifier can be used when writing to the file,
# thus making it possible to overwrite previous iterations of the same code block.
# The use case for this extension is to export selected code from a Notebook for 
# reuse through a .py file.
