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