Have a look at /usr/local/etc/rc.d
All scripts that are executable and end in ".sh" in that directory get=20
executed at boot-time. You could create your own scripts in that director=
y=20
that starts your application.

On boot the scripts are executed with the first agrument being "start". O=
n=20
shutdown the scripts are executed with "stop" as first argument. By check=
ing=20
the argument in your script you can determine if you should start the=20
application or not. (Don't start it at shutdown :)

A simple rc.d-script could look something like this :
--- cut here ---
#!/bin/sh
case "$1" in
start)
=09/some/dir/some-app && echo -n ' some-app'
        ;;
stop)
        ;;
*)
        echo "Usage: `basename $0` {start|stop}" >&2
        ;;
esac
exit 0
--- cut here ---

The "echo -n" line is the output you see when you boot your system after =
:
"Local package initialization :"
This only works on applications that daemonize (dissapear into the backgr=
ound=20
when you start them). If your program doesn't daemonize, you should start=
 it=20
with an "&" sign behind it...
