What's 'modules package'?

This work has not been started yet. It would be extremely cool if you
could flesh out something on that cookbook page. We could throw it
into the IPython manual.

There is a syntax for this:

o = !some_command foo bar

Command output is not by default captured to _, because it would
require us to change the execution model; now the terminal commands
are executed in a fully interactive fashion (os.system()), and I
wouldn't really like to change that, at least as default.

However, it would be very easy to implement a system where system
command output was available in Out array, but the commands would not
be executed "naturally" then.

What does $! do? If there in no equivalent yes, we can do it ;-)
