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.
