/*
|
|
* 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.
