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.
