Free openpkg software for linux

OpenPKG is a flexible and powerful software packaging facility that eases installation and administration of Unix software across several platforms.
Consolidating different vendor approaches into a unified architecture, it assists in administration of large networks previously complicated by nonconformant systems. It uses RPM to provide an additional system layer on top of the operating system.
It is fully self-contained (no RPM pre-installation is required), installs itself by means of a tricky bootstrapping procedure with minimal operating system intrusion, and supports multiple installation instances.
