Cfengine, or the configuration engine is an agent/software robot and a very high level language for building expert systems to administrate and configure large computer networks. Cfengine uses the idea of classes and a primitive form of intelligence to define and automate the configuration and maintenance of system state, for small to huge configurations. Cfengine is designed to be a part of a computer immune system. WWW: http://www.iu.hioslo.no/cfengine/
