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