If you're running a mixed Debian system and wonder just how mixed your system is, this script is for you.
Preferably check the more up-to-date Github version.

#!/usr/bin/env bash

set -e

    cat << EOF
NAME
    $SCRIPTNAME - check how mixed (or unmixed) your system is

SYNOPSIS
    $SCRIPTNAME [OPTION]

DESCRIPTION
    The script uses apt-show-versions to gather information about
    package repositories (names, quantity and percent of the packages in system)
    used in the current Debian install.

    -m, --show-missing  Print package names that are not found in any
                        repository. These normally consist of obsolete packages
                        or packages installed outside APT.

    -h, --help          Show usage and exit.
    -V, --version       Show version info and exit.
