How to make piaware start ONLY manually?

Jessie image from main raspberry pi home page, I did the 3.1.0 repository as per:

flightaware.com/adsb/piaware/install

What I’m looking to have is manual control on when I start and stop piaware/dump1090/webserver (or whatever is answering on :8080), as I use this Pi on offline networks, I want to use the DVB dongle to receive FM radio, etc using GQRX, etc.

Thanks!
