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 speci-
       fies the  priority  of  the  value;  when  options  are  queried  using
       Tk_GetOption,  the value with the highest priority is returned.  Prior-
       ity 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 databases loaded into the X server, or
              user-specific startup files.

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