57 /* TODO (tl): This Windows version of dbus-launch is curretly rather
58 * pointless as it doesn't take the same command-line options as the
59 * UNIX dbus-launch does. A main point of the dbus-launch command is
60 * to pass it for instance a --config-file option to make the started
61 * dbus-daemon use that config file.
63 * This version also doesn't print out any information, which is a
64 * main point of the UNIX one. It should at least support the
65 * --sh-syntax option, and maybe also a --cmd-syntax to print out the
66 * variable settings in cmd.exe syntax?
68 * NOTE (rh): The main task of dbus-launch is (from the man page) to start
69 * a session bus and this is archieved by the current implemention.
71 * Additional on windows the session bus starting in not integrated
72 * into the logon process, so there is no need for any --syntax option.
73 * In fact (at least for kde on windows) the session bus is autostarted
74 * with the first application requesting a session bus.
