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 databases
              loaded into the X server, or user-specific startup files.

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