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