12203559Skientzle * Macros to define the method of doing filename "globbing".
13248616Smm * There are three possible mechanisms:
14203559Skientzle *   1.	GLOB_LIST
15203559Skientzle *	This defines a function that returns a list of matching filenames.
16203559Skientzle *   2. GLOB_NAME
17203559Skientzle *	This defines a function that steps thru the list of matching
18224153Smm *	filenames, returning one name each time it is called.
19291620Sbdrewery *   3. GLOB_STRING
20224153Smm *	This defines a function that returns the complete list of
21299529Smm *	matching filenames as a single space-separated string.
