Cfengine is an automated suite of programs for configuring and 
maintaining Unix-like computers. It has been used on computing arrays 
of between 1 and 20,000 computers since 1993 by a wide range of 
organizations. Cfengine is supported by active research and was the 
first autonomic, hands-free management system for Unix-like operating
systems. Cfengine is an autonomic maintenance system not merely a
change management roll-out tool. Cfengine has a history of security
and adaptability.
