madison-lite binary package in Ubuntu Focal amd64

 This program inspects a local Debian package archive and displays the
 versions of the given packages found in each suite (for example, stable,
 testing, or unstable) in a brief but easily human-readable form. It aims to
 be a drop-in replacement for the madison utility from the da-katie archive
 management suite that runs on the central Debian archive systems, but one
 which can run without access to the archive's SQL database.
 .
 For simple queries, you can use http://packages.debian.org/ instead, which
 does not require you to have access to a system with a local mirror.
