:   '''[wm] client''' ''window'' ?''name''?

If ''name'' is specified, this command stores ''name'' (which should be the name of the host on which the application is executing) in ''window'' 's '''WM_CLIENT_MACHINE''' property for use by the window manager or session manager. The command returns an empty string in this case. If ''name'' isn't specified, the command returns the last name set in a '''wm client''' command for ''window''. If ''name'' is specified as an empty string, the command deletes the '''WM_CLIENT_MACHINE''' property from ''window''.

----
The '''wm client''' command is used to provide some level of compliance with the [ICCCM]. In order for the session manager to be able to restore an application, it must know on which host the application is running. The best way to do this is:
======
   wm client . [info hostname]
======
You should also use the [wm command] command to set the application command, the most basic way being:
======
   wm command . [linsert $argv 0 $argv0]
======
