As the names should suggest, the script _etc_init.d_assp should be moved
to /etc/init.d/assp, while the configuration file _etc_default_assp
should be moved to (guess...) /etc/default/assp

After configuring the file /etc/default/assp with the values correct for
your installation (I usually install it in /srv/assp as you can see) a
simple "update-rc.d assp defaults" completes the configuration.
