package manager for RPM

 The RPM Package Manager (RPM) is a command-line driven package
 management system capable of installing, uninstalling, verifying,
 querying, and updating computer software packages.

 On Debian and derived systems it is recommended to use "alien" to
 convert RPM packages into .deb format instead of bypassing the Debian
 package management system by installing them directly with rpm.
