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 user-specific startup files.

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