Security-enhanced Linux is a patch of the Linux kernel and a number of
utilities with enhanced security functionality designed to add
mandatory access controls to Linux. The Security-enhanced Linux kernel
contains new architectural components originally developed to improve
the security of the Flask operating system. These architectural
components provide general support for the enforcement of many kinds of
mandatory access control policies, including those based on the
concepts of Type Enforcement, Role-based Access Control, and
Multi-level Security.

This package contains checkpolicy, the SELinux policy compiler. Only
required for building policies.
