It is a small wrap-up script (or bin?) around the control file (e.g. /var/run/xl2tpd/l2tp-control). Originally, xl2tpd is controlled by writing commands into the control file, the way kernel often uses in /proc/ and /sys/. Some distributions provide this handy tool, but others not.
If we echo strings to the control file directly, we can remove the dependency on xl2tpd-control.
