The SELinux Reference Policy project (refpolicy) is a complete SELinux policy
that can be used as the system policy for a variety of systems and used as the
basis for creating other policies. Reference Policy was originally based on
the NSA example policy, but aims to accomplish many additional goals:
+ Strong Modularity
+ Security Goals
+ Documentation
+ Development Tool Support
+ Forward Looking
+ Configurability
+ Flexible Base Policy
+ Application Policy Variations
+ Multi-Level Security
