     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.
