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.
