Multiple Rails apps on OS X without configuration pain

I recently stumbled upon Pow. It helps you running multiple Rails applications without you needing to change ports or the hosts file.

Just install, link applications and visit http://my_app.dev in the browser of your choice.

Restart as known from Passenger using touch tmp/restart.txt.

Only If you are using additional services, you have to start them in addition.
