Subject:   rc script for a program - detach from tty?

I am trying to find a way to run this program and make it detach from the
tty.
I can get it to start if I run it in the background, but maybe there is a
better way than this?
Also when it starts, it launches several children and I have to kill it
using this brutal way, which doesn't look quite dandy.

PS: I have also been able to run it with supervisor, but killing it still
requires this very brutal method :-)

I hope someone can help modify this script to handle the start|stop in a
much cleaner way.
