copy_evidence.sh

#! /bin/bash

# A stupid script so that files copied to an archive for 
# evidence are logged into the common inventory, along with
# inventory for the create_image.sh and review_drive.sh scripts
#
# -= Usage =-
# Usage: copy_evidence <source> <destination>
#
# NOTE:  Destination should be the root of your archive mount
#
# TODO: 
#   - more elegant failure of a match
#   - deletion of source material (make it an option?)
#   - not such an ugly multi-nested if statement?
