I guess "embedding" isn't the correct word for the first option, but I was just referring to the part under the **Qt and the QtConsole** heading: instead of embedding the QtConsole in the app, (I guess that) you can instead start the app from IPython, reusing the QCoreApplication started by passing `--matplotlib qt` to IPython.  In a sense you're then embedding your app inside IPython instead of IPython inside your app.

But I only added this option so that the **Qt and the QtConsole** section doesn't get completely disconnected from this section; perhaps we can completely do without it instead (I have never tried it, in fact).
