Options:
  --window <regexp>         A regular expression matching the window title
                            If you do not specify one, then the very first window
                            to appear will be taken - not recommended.
  --wid <int>               The window id of the target window
                            Specifies the id of the window to use. If the id starts with 0x
                            it is assumed to be in hex.
  --hidden                  Hide the window to the tray on startup
  --startonshow             Wait until we are told to show the window before
                            executing the command
  --tooltip <text>          Sets the initial tooltip for the tray icon
  --keeprunning             Keep the tray icon even if the client exits. This option
                            has no effect unless startonshow is specified.
  --ownicon                 Use ksystraycmd's icon instead of window's icon in systray
                            (should be used with --icon to specify ksystraycmd icon)
  --ontop                   Try to keep the window above other windows
  --quitonhide              Quit the client when we are told to hide the window.
                            This has no effect unless startonshow is specified and implies keeprunning.
