#! /bin/bash
#
# Tool to produce lists of MD5 sums for files in subdirectories.
#
# Assumption is that $rootdir contains directories.  Each directory
# is a virtual host, or some other set of files for a domain.
# A report is produced for each directory.  The report is stored
# in a parallel directory structure.  By conventions we have
# directories like reports/www/domain.com, reports/mail/domain.com
# and the reports are named $hostname.md5
#
# The comparison script, backup-compare-sums.sh compares between
# two of these reports.  See that script for more info.
