CFEngine 3 is a popular open source configuration management system.
Its primary function is to provide automated configuration and
maintenance of large-scale computer systems.

The repository is intended to provide a stable base policy for
installations and upgrades, and is used by CFEngine 3.6 and newer.
The port installs the repository as examples which should be copied by
the user to the masterfiles directory (usually /var/cfengine/masterfiles).
