A package manager is a collection of tools which automates the process of
installing, upgrading,
configuring, and removing software or settings in a consistent manner.
A package manager deals with packages, distributions of software and data in archive files.
Packages contain metadata, such as copyright/license, vendor, checksum,
description, version, requirements
and a list of dependencies for chained
automatic installation which is nessesary for this software to run correctly.
