+Launchd[1,2] replaces init, inetd and cron on Mac OS X since 10.4 "Tiger".
+dbus uses this service to provide a common session bus address for each user
+and so deprecates the X11 enabled dbus-launcher.
+
+[1] http://developer.apple.com/MacOsX/launchd.html
+[2] http://launchd.macosforge.org/
+
+
+Setup
+===
+
+Configure with --enable-launchd and --without-x (X11 should not harm but it's
+simply not necessary any more)
+After installation, to prevent a reboot, load the dbus session starter into
+launchd by executing:
+$ launchctl load /Library/LaunchAgents/org.freedesktop.dbus-session.plist
+
+You can change the launch agent dir via configure, but it's not recommended.
+Make sure to execute the above line as the actual user for which you want to
+use a session bus since launchd manages its agents on a per user basis.
+
+
+How it works
+===
+
+Launchd allocates a socket and provides the unix path to it via the variable
+DBUS_LAUNCHD_SESSION_BUS_SOCKET in launchd's environment. Every process
+spawned by launchd (or dbus-daemon, if stared by launchd) can access it through
+its own environment. Other processes can query launchd for it by executing:
+$ launchctl getenv DBUS_LAUNCHD_SESSION_BUS_SOCKET
+However, this is normally done by the dbus client lib for you.
+
+If launchd start dbus-daemon with a config file containing a "launchd:env=FOO"
+address, as the default session config does with env=DBUS_LAUNCHD_SESSION_BUS_SOCKET,
+the daemon will get the file descriptor from launchd and start listening on it.
+The environment variable is used to get the actual socket path which is passed
+to every service spawned by dbus-daemon as a result from autolaunch messages.
+Please note that it's not possible to start dbus-daemon manually when using a
+"launchd:" address. Only child processes of launchd can access the above
+mentioned file descriptor!
+
+To create custom buses just set up an other launch agent. As a quick start copy
+/Library/LaunchAgents/org.freedesktop.dbus-session.plist, change the label
+to i.e. "org.freedesktop.dbus-foo" and change the SecureSocketWithKey value,
+i.e. to "DBUS_LAUNCHD_FOO_BUS_SOCKET". This environment variable has to be set
+in the config file for your new bus in the <listen> element (see session.config).
+Then edit your /Library/LaunchAgents/org.freedesktop.dbus-foo.plist to start
+dbus-daemon with "--config-file=/opt/local/etc/dbus-1/foo.conf" instead of
+"--session". Now load the new plist onto launchd as described in the setup
+section of this document.
+Executing "launchctl export" should now give you two sockets, one in
+DBUS_LAUNCHD_SESSION_BUS_SOCKET and the new DBUS_LAUNCHD_FOO_BUS_SOCKET.
+To connect to this new bus use "launchd:env=DBUS_LAUNCHD_FOO_BUS_SOCKET".
+
+Since Mac OS X 10.5 "Leopard" you can also configure launchd to start
+dbus-daemon on demand as soon as some process connects to the socket. Since
+it's broken on 10.4 this feature is disabled per default. Look at
+/Library/LaunchAgents/org.freedesktop.dbus-session.plist to change it.
+
+On the client side, the envvar DBUS_SESSION_BUS_ADDRESS can be normally used
+but if it's not set, launchd is queried for the session bus socket.
