# DESCRIPTION:
#
# Directory structure of snapshots reflects filesystem structure.
#
# STRATEGY:
#
# This test makes sure that the directory structure of snapshots is
# a proper reflection of the filesystem the snapshot was taken of.
#
# 1. Create a simple directory structure of files and directories
# 2. Take a snapshot of the filesystem
# 3. Modify original filesystem
# 4. Walk down the snapshot directory structure verifying it
# checking with both absolute and relative paths
#
