Dear Customer,

this package does no provide any files any more, but triggers the
installation of both, IKEv1 (pluto) and IKEv2 (charon) daemons and
the traditional starter scripts inclusive of the /etc/init.d/ipsec
init script and /etc/ipsec.conf file.

There is a new strongswan-nm package with a NetworkManager plugin
to control the charon IKEv2 daemon through D-Bus, designed to work
using the NetworkManager-strongswan graphical user interface.
It does not depend on the traditional starter scripts, but on the
IKEv2 charon daemon and plugins only. 

Have a lot of fun...
