Some questions about openhd-router, ophd-micorservice, qopenhd, openhd-linux-pi

I notice the “fpm -d” cmd in the package.sh. I know openhd-router, ophd-micorservice, qopenhd, openhd-linux-pi, are dependecies of OpenHD. What are the functions of these four dependencies. Are these open source ?

They are all open and on github. You can look at them here
