usage:
$SCRIPT -d directory [-n]
-d directory directory to be created.
-n never prompt when removing existing directory.
Attempts to safely create an empty directory. If -n is not
specified, the script will prompt before deleting any files
or directories. If -n is specified, it will not prompt.
The safety measures include refusing to run if run by user
root and by refusing to create directories unless there are
a subdirectory of /tmp or have at least two ancestor
directories... /grandparent/parent/child.
******************** WARNING ********************
This script will destroy existing directories and
their contents. It can potentially wipe out your
disk. Use with caution.
