.SH DESCRIPTION
Emit csh compatible code to set up environment variables.
.TP
-.I \-\-exit\-with\-x11
-If this option is provided, a persistent "babysitter" process will be
-created, and will connect to the X server. If it cannot do so, launching
-fails. If the "babysitter" process loses its X connection,
-it kills the message bus daemon, disconnecting all of its clients (which
-should exit in response). This avoids having leftover daemon
-processes from a user X session, after the X session has ended.
-
-.TP
-.I \-\-exit\-with\-session
-If this option is provided, a persistent "babysitter" process will be
-created, as if for
-.BR \-\-exit\-with\-x11 .
-If it cannot connect to the X server, it will monitor the terminal from which
-.B dbus-launch
-was started instead, and if it gets a HUP on stdin, the message bus daemon
-will be killed. This option is not recommended, since it will consume input
-from the terminal where it was started; it is mainly provided for
-backwards compatibility.
+.I "\-\-exit\-with\-session"
+If this option is provided, a persistent "babysitter" process will be
+created that watches stdin for HUP and tries to connect to the X
+server. If this process gets a HUP on stdin or loses its X connection,
+it kills the message bus daemon.
