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 for-
     mat.  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 (100).  Some common priority values are:

     TK_WIDGET_DEFAULT_PRIO
			 Used for default values hard-coded into widgets.

     TK_STARTUP_FILE_PRIO		     Used  for	options specified in ap-
					     plication-specific startup files.

								 server,      or
								 user-specific
