DESCRIPTION
       This procedure is invoked to add an option to the database associated with tkwin's main window.  Name
       contains the option being specified and consists of names and/or classes separated  by  asterisks  or
       dots,  in the usual X format.  Value contains the text string to associate with name; this value will
       be returned in calls to Tk_GetOption.  Priority specifies the priority of the value; when options are
       queried  using  Tk_GetOption,  the  value  with  the  highest priority is returned.  Priority must be
       between 0 and TK_MAX_PRIO.  Some common priority values are:

       20     Used for default values hard-coded into widgets.

       40     Used for options specified in application-specific startup files.

       60     Used for options specified in user-specific defaults files, such as .Xdefaults, resource data-bases databases
              bases loaded into the X server, or user-specific startup files.

       80     Used for options specified interactively after the application starts running.
