| Running ${PKGSTEM} on OpenBSD
+-----------------------------------------------------------------------

To enable ConsoleKit in a graphical session, prepend ck-launch-session
to the session script (note: gdm(1) does this automatically). e.g.
    ${PREFIX}/bin/ck-launch-session ${PREFIX}/bin/openbox-session

Note that you need a system-wide DBus daemon running.
