+"""A sample application for integrating cmd2 with external event loops.
+
+This is an example of how to use cmd2 in a way so that cmd2 doesn't own the inner event loop of your application.
+
+This opens up the possibility of registering cmd2 input with event loops, like asyncio, without occupying the main loop.
