DESCRIPTION
       Tk_Init	is  the package initialization procedure for Tk.  It is normally invoked by the Tcl_AppInit procedure for an application or by the
       load command.  Tk_Init adds all of Tk's commands to interp and creates a new Tk application, including its main window.	If the initializa-
       tion  is  successful  Tk_Init returns TCL_OK;  if there is an error it returns TCL_ERROR.  Tk_Init also leaves a result or error message in
       interp->result.

       If there is a variable argv in interp, Tk_Init treats the contents of this variable as a list of options for the new Tk	application.   The
       options may have any of the forms documented for the wish application (in fact, wish uses Tk_Init to process its command-line arguments).

       Tk_SafeInit  is identical to Tk_Init except that it removes all Tk commands that are considered unsafe.	Those commands and the reasons for
       their exclusion are:

       bell   Continuous ringing of the bell is a nuisance.

       clipboard
	      A malicious script could replace the contents of the clipboard with the string "rm -r *" and lead to surprises when the contents	of
	      the clipboard are pasted.

       grab   Grab can be used to block the user from using any other applications.

       menu   Menus can be used to cover the entire screen and to steal input from the user.

       selection
	      See clipboard.

       send   Send can be used to cause unsafe interpreters to execute commands.

       tk     The tk command recreates the send command, which is unsafe.

       tkwait Tkwait can block the containing process forever

       toplevel
	      Toplevels can be used to cover the entire screen and to steal input from the user.

       wm     If toplevels are ever allowed, wm can be used to remove decorations, move windows around, etc.
