Module Name:
tree.cxx
Abstract:
This module contains the implementation of the TREE class.
The TREE class implements a tree utility functionally compatible
with the DOS 5 tree utility.
This utility displays the directory structure of a path or drive.
Usage:
TREE [drive:][path] [/F] [/A] [/?]
/F Display the names of files in each directory.
/A Uses ASCII instead of extended characters.
/? Displays a help message.
