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