The psys library provides a simple interface to the system package manager of a Linux system. It allows installation programs to notify the package manager of the installation, uninstallation, and update of third-party software packages, and to request these packages to be added to or removed from the system package database. The psys library interface is generic and not tied to a specific package management system or Linux distribution; it is meant to be a proposal for a future version of the LSB standard.
