+and de-serializing Python objects to the majority of the built-in Python
+types.  Dill provides the user the same interface as the @code{pickle} module,
+and also includes some additional features.  In addition to pickling Python
+objects, @code{dill} provides the ability to save the state of an interpreter
+session in a single command.  Hence, it would be feasable to save a
+interpreter session, close the interpreter, ship the pickled file to another
+computer, open a new interpreter, unpickle the session and thus continue from
+the saved state of the original interpreter session.")
