  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.
