A file-like object is an object that is not a file object, but behaves
like a file object. Instead of keeping the data on disk, it will use
Python objects (e.g. str or maybe array.array) or malloc its own
memory. Have a look at the StringIO module (pure Python) and the
similar but faster cStringIO module.
