$self checks the MD5 sums of installed debian packages.

Usage: $self [OPTIONS] [PACKAGE|DEB] ...

Options:
 -a, --all                    check configuration files (normally excluded)
 -e, --config                 check only configuration files
 -c, --changed                report changed files (implies -s)
 -l, --list-missing           list packages which don't have an md5sums file
 -s, --silent                 only report errors
 -m, --md5sums=FILE           read list of deb checksums from FILE
 -x, --report-mismatches      report errors and print the md5sums mismatch
 -r, --root=DIR               root directory to check (default /)
 -d, --admindir=DIR           dpkg admin directory (default /var/lib/dpkg)
 -p, --deb-path=DIR[:DIR...]  search path for debs
 -g, --generate=[all][,keep[,nocheck]]
                              generate md5sums from deb contents
     --no-locale-purge        report missing locale files even if localepurge
                              is configured
     --no-prelink             report changed ELF files even if prelink is
                              configured
     --ignore-obsolete        ignore obsolete conffiles.
     --help                   print this help, then exit
     --version                print version number, then exit
