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