[IPython-dev] notebook-like format for IPythonQt sessions.

Whatever the format for saving sessions is chosen, I think it would be a
great idea if one could execute a whole notebook from the terminal with
something like:

ipython -nb foo.inb (inb = ipython notebook)

or call it with the %run magic. This way you could write self-contained
programs with IpythonQt and use ipython as an interpreter to run them.

I'm very fond of literate
programming<http://en.wikipedia.org/wiki/Special%3ASearch/literate_programming>and
I think it would be very useful to write programs as text (with
sections, subsections, equations, figures, etc) but with the possibility to
run them as easily as possible.
