# This script will make a best-effort attempt at showing modifications
# to package-provided config files on a Debian system.

# It's subject to some pretty significant limitations: most notably,

# that most of the time, if maintainer scripts are managing files
# themselves, they're using ucf. So, DO NOT TRUST THIS SCRIPT to find
