     15  * Macros to define the method of doing filename "globbing".
     16  * There are three possible mechanisms:
     17  *   1.	GLOB_LIST
     18  *	This defines a function that returns a list of matching filenames.
     19  *   2. GLOB_NAME
     20  *	This defines a function that steps thru the list of matching
     21  *	filenames, returning one name each time it is called.
     22  *   3. GLOB_STRING
     23  *	This defines a function that returns the complete list of
     24  *	matching filenames as a single space-separated string.
