52 *
53 * Portability note: The utility depends upon the host for command-line
54 * wildcard support - it is not implemented locally. For example:
55 *
56 * Linux/Unix systems: Shell expands wildcards automatically.
57 *
58 * Windows: The setargv.obj module must be linked in to automatically
59 * expand wildcards.
